Problems of the Country an Example by

Problems of the Country by Expert Marvellous | 22 Dec 2016 1. One of the problems facing the US today is that of illegal migration. According to the estimates of the INS (currently CIS), in January 2000, the total population of illegal migrants in the US comprised 7 million people (CIS 2003). Out of those, 32% lived in California, and largest increases in the numbers of illegal aliens were also posted in Texas, Arizona, Illinois, Georgia, and North Carolina (CIS 2003). Need essay sample on "Problems of the Country" topic? We will write a custom essay sample specifically for you Proceed The estimates of the Census Bureau show an even higher number, 8 million illegal aliens living in the US as of 2000. The Center for Immigration Studies finds that the two "magnets" which attract illegal aliens are jobs and family connections. Discrepancy in salaries between American workers and those in developing nations drive people across the border. The result is illegal networks that help channel new entrants across the border. Despite measures taken to combat the problem, the flow does not abate. Angela Kelley, deputy director of the National Immigration Forum, states that the continued growth of that population simply shows that current immigration policy "is broken" (Moreno 2005:A02). One way to combat illegal migration is to supply all legal entrants as well as citizens with some sort of ID that will be required in virtually all establishments: banks, supermarkets, stores etc. The lack of such identification will become instant proof of illegal status or indication of need to perform a background check for the police or other law enforcement bodies. Another serious problem that emerged only recently is the incumbent Administrations crackdown on free exchange of information. Especially worrisome is White House's directive that allows the NSA to monitor the calls and e-mails of Americans without court approval (Arlen Specter to Dick Cheney: Butt Out on Wiretap Probe). The initiative is assumed to violate the constitutional rights of Americans. Yet it is presented as an important tool in combating terrorism and was labelled by the President as a terrorist surveillance program (Bush Defends). It seems necessary in this respect to introduce additional legislation that will protect civil liberties in the face of the stepped up efforts in the fight against terrorism. The new acts have to outlaw any indiscriminate tapping of phones or e-mails, subjecting them to the court approval. 2. One of the future problems that have attracted a lot of debate is the projected shortfall in Social Security. Washington Posts editorial No Social Security 'Crisis' cites the projections of a gap of $3.7 trillion in the next 75 years. The solutions are delayed because politicians do not risk voting for unpopular measures that may alienate voters. Some politicians even question the very existence of the crisis. Thus, R-Calif. Bill Thomas insisted that lawmakers have to reach a consensus on the level of urgency and the magnitude of the problem (Lawrence 2005). However, independent analysts arrived at the conclusion that the Trustees' projections for productivity, labor force growth, and longevity show the projections to be reasonable and perhaps even optimistic (Biggs 2000). Slow growth of the economy combined with aging of the population is bound to result in shortfall in Social Security. While it is clear that seniors may have to work longer in order to provide for themselves, it makes sense to start a program creating special senior jobs. These jobs can be offered to people over 65 who are still willing to put in a few hours a day. Either corporations or special entities can find ways to utilize the expertise and experience accumulated by seniors without straining their fragile health. Another problem that will surface in the nearest future is the need to accommodate soldiers returning from Iraq. Many soldiers discovered that homecoming proved a far more complicated, even conflicted, experience than it seemed it would be back in Iraq when they thought of little else (Myers 2003). The soldiers often encounter the so-called Vietnam syndrome manifested in alienation, depression and a range of psychological disorders (Satel 2004). Even if they feel more or less sound psychologically, there is a new problem: many veterans are struggling with finding work as their long absence from the workforce and psychological problems make them less attractive to employers (Reserve soldiers at a loss for jobs). The solution for soldiers problems can come from soldiers unions, but should be facilitated by the government. Thus, the federal government can offer an incentive plan to businesses that want to hire soldiers returning from the war. Incentives can be offered in the form of tax breaks or additional guarantees for loans taken out by businesses that hire 3 or more Iraqi veterans. 3. I do hope that the US can address its problems with due effort. Throughout the centuries, this nation faced a variety of challenges, yet each time emerged vigorous and able to protect itself from future challenges. The strong civil institutions including non-governmental organizations and independent press are a powerful means of identifying problems. The mechanisms for their resolution do not always prove effective, but they reflect ultimately the evils of society that is not always capable of adequate action. Our country does not face the serious challenges that confront developing nations such as access to fresh water, basic sanitation etc. However, the problem of the US is that it is already a great power with much to lose. It takes effective and imminent action to remedy the problems in order to continue as a great power. References Bush Defends NSA Electronic Surveillance Program.

Dont Wish Your Life Away †Theology Essay

Dont Wish Your Life Away – Theology Essay Free Online Research Papers Don’t Wish Your Life Away Theology Essay If you were given three personal wishes that would be certain to come true, what would they be? Some people are big on wishing. They throw coins in a fountain or wishing well, vie for the wishbone of the turkey, regularly thumb through their favorite wish book, religiously blow out all the candles of their birthday cake, and some dreamily wish upon a star. Sadly, most people’s wishes end in disappointment, regret, or resignation. The New Oxford American Dictionary defines â€Å"wish† as â€Å"feel or express strong desire or hope for something that is not easily attainable; want something that cannot or probably will not happen . . . silently invoke such a hope or desire†. Perhaps you have heard phrases such as: â€Å"If wishes were horses, beggars would ride†. For many a wish is a desire that they don’t’ really expect to be filled. Some want a magic wand to bring about their wish without any effort or change on their part. My friend, Bill, got my attention the other day. While talking with some friends, Jenny mentioned that it seemed like Friday to her, even though it was only Tuesday. I remarked, â€Å"I wish it was Friday!† Bill quickly responded, â€Å"Don’t wish your life away, time goes fast enough!† I believe he was right. We miss so much because we don’t live or utilize the present. Simply wishing will waste energy and opportunities we have now. Wishing alone will not take us to our goals or desires. Someone has said, â€Å"It takes as much energy to wish as it does to change.† Some people never reach their goals because they wish their life away or sleep it away. How can we turn our wishes into passionate wants and passionate wants into winning ways? First – PRAY, DELIGHTING IN THE LORD. When you make God your utmost delight, your disorder becomes ordered, your confusion will become peacefully clear, and discord – harmony. When one is out of sync with God, they tend to wander in circles. After deliverance from Egypt, it took 40 years for the Israelites to get to the Promised Land. What was the problem? They were out of â€Å"sync† with God. (See I Corinthians 10:1-13.) David tells us, â€Å"Delight yourself in the Lord, and He will give you the desires of your heart. Commit your way to the Lord; trust also in Him, and He will do it† (Psalm 37:4). Gordon McDonald in his book Ordering Your Private World directs us to this priority. Pray for God’s will and purpose for your life. (See Jeremiah 29:11-12 and Matthew 6:33.) Second – PASSIONATE DREAMS will motivate you to make needed changes and take the necessary risks to move out of your comfort zone. Study the dreams and life of Abraham. It moved him out into the unknown, totally trusting God. (See Genesis 12 – 15 and Hebrews 11.) What passion are you embracing? Third – PROCEED DELIBERATELY. Wishing is not enough. We must take deliberate steps. Perhaps baby steps at first. â€Å"By faith . . . Abraham went out† (Hebrews 11:8-12). Abraham believed his challenges were opportunities. He looked to the new and exciting opportunities God put before him. Like Abraham, we must take positive action to develop discipline, motivation, perseverance, and obedience to God, to reach our goals and dreams. Fourth – YOUR PAST MUST BE DEEPLY BURIED. Forget any mistakes or failures of yesterday. We should learn from them, but don’t dwell on them. Move ahead. God forgives and forgets, so why don’t you? (See Psalms 103:3, 4, 10, 11 and Philippians 3:13.) John F. Kennedy said, â€Å"Change is the law of life and those who look only to the past or present are certain to miss the future.† Fifth – PART WITH DEAD WEIGHT. Anything that doesn’t support your dream, that which is most important to you, needs to be laid aside. Anything that interferes with your goal must be abandoned. Why spend energy, resources, time, and give space to activities or things that do not help advance your goals and dreams? Are there habits, attitudes, things, or sins that hold you back? Part with them. (See Hebrews 12:1-2.) Sixth – GOD’S PROMISES DEVELOP FAITH. There are three enduring qualities that will propel you toward your dreams: faith, hope, and love. (See I Corinthians 13.) Believing and embracing the promises of God will release His presence and power into your life. God’s Word reveals that the Israelites had the promises of God, but it didn’t profit them because they were not mixed with faith. (See Hebrews 4:2 and 11:6.) Problems can’t be ignored, but as we focus on the promises and power of God, they can be turned into opportunities to bring God glory and reach our God given dreams. Seventh – PUT ON THE DIFFERENT, NEW MAN. â€Å"And that you put on the new man, which after God is created in righteousness and true holiness† (Ephesians 4:24). Many wish they were a different person, a different father, mother, or spouse. In Christ, you can become a new creation. â€Å"Therefore, if any man be in Christ, he is a new creature; old things are past away; behold, all things are become new† ( II Corinthians 5:17). Abraham became a new man. â€Å"Abraham believed God and it was counted unto him for righteousness† (Romans 4:3). Don’t wish your life away, believe God. â€Å"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in Him, should not perish, but have everlasting life† (John 3:16) Research Papers on Don’t Wish Your Life Away - Theology EssayThe Hockey GameHarry Potter and the Deathly Hallows EssayCanaanite Influence on the Early Israelite Religion19 Century Society: A Deeply Divided EraNever Been Kicked Out of a Place This NiceHip-Hop is ArtWhere Wild and West MeetCapital PunishmentEffects of Television Violence on ChildrenHonest Iagos Truth through Deception

English - Essay Example To be precise, the character of Crenshaw plays a very important role in giving a realistic touch to Messina town and the influence of football on its people. The following narration given by the author gives a clear note on Crenshaw’s character as well as the main reason, which has stick him to Messina. "†¦he vowed to return more often. Messina was the only hometown he knew. The best years of his life were there. He’d come back and watch the Spartans on Friday night, sit with his friends and when the name of Eddie Rake was mentioned, he would smile and maybe laugh and tell a story of his own. One with a happy ending." â€Å"The math had never worked. However, they piled in from the county, from out in the sticks where there was nothing else to do on Friday night. in every window of every store around the Messina square there was a large green football schedule, as if the customers and townsfolk needed help in remembering that the Spartans played every Friday."The setting of the novel is completely written over Messina with specific attention given to football matches and its strong influence on the people of Messina. Most of the recollections of Crenshaw cover up the football matches in which majority of Messina’s people would come to see. The conflict between innocence and maturity, reason and reality keeps the story of Montana 1948 move with suspense and interest. David’s expedition to the frequent deaths happening within their living atmosphere, and the rivalry of power, which takes place between his grandfather and his own father, enhances the curiosity of David. The difference between the visions of a 12-year-old boy and a grown up boy holds the essence of the plot. The reasons which he [David] would like to explore with the events that happens after the death of their maid woman, and the understandings which he associates with his own realisation as well as his father’s helps a lot to understand the

Leadership Development Dissertation Example | Topics and Well Written Essays - 10500 words

Leadership Development - Dissertation Example Chapter 1 Introduction 1.1. Purpose of the study "Leadership development needs organization managers," Whilst in the past, as our research shows, most observers and experts had tended to view Leadership, and leadership development, as an independent area of consideration within the corporate structure, over the past two decades it has been increasingly seen to be an integral part of the total organization management system itself. Consequently, research often links the two areas together. There are an abundance of studies and research documents confirming this fact. These include that of Zaleznick (1977), who defined the leader as the person who brings about change, with the manager being the controller of those changes. Kotter (1990, p. 103) projected the view that "management is about coping with complexity. Leadership, by contrast is about coping with change". The purpose of this report is to examine the validity of the hypothesis. 1.2. Specific Objective This central objective of this report is to examine the opening hypothesis in order to arrive at a conclusion as to its validity and importance. 1.3. Delimitations For the purpose of this report, we have limited our study to the subject as it relates to a commercial organization, in preference to organizations in the public or charitable sector, although in reality the same principles would form the basis for measuring the successful future growth pattern for all of these structures. 1.4. Significance Our study covers the current thinking and research in respect of the leadership developments and its application in the corporate environment, including an analysis its importance and relevance. At the same time, we have reviewed and studied the research available regarding the... The literature will reveal how changes have occurred between these three elements, with the initial concept of management, which has been around since the early part of last century, is seen as the driving force behind the business. Later management was to lose its significance, giving way to the relatively new concept of leadership, with this taking a prominence in the thoughts of corporations and researchers alike. We will see how the views of business analysts and researchers for a period separated leadership and leadership development from management and conducted studies of these in these areas as almost diverse entities, emphasizing the differences between the two. For example, the School of Engineering and Electronics at the University of Edinburgh (1997), in their study on the subject, concluded that – â€Å"Managing and leading are two different ways of organizing people. The manager uses a formal, rational method whilst the leader uses passion and stirs emotions.† Dr. Paul Harborne (2001) and Stormy Friday (2002) within their respective papers also emphasized differences that exist between these conceptions, stressing the importance that this represented in business terms. However, more research has moved away from these theories, suggesting now that in fact, there is an interrelationship between the leadership and management, and that a competitive and successful business is best achieved in an environment where leadership development and the organization's managers work in partnership.

Behavioural and Cognitive Counselling Theory Essay

Behavioural and Cognitive Counselling Theory - Essay Example He developed his approach because he did not agree with the widely popular psychoanalytic approach to therapy (NACBT, 2008). Before the 18th century studies and conceptualizations in mental and psychiatric health was still interpreted in terms of the supernatural and the moral notions of human ills (McGuire, n.d). The Rationalist theory, introduced in the 18th century, was later able to establish patterns of thinking; conceptualizations of the social contrast; and other concepts of criminal behaviour, motivation, and morality. Other more scientific rationalizations soon followed. Cognitive psychology was very much rooted in the rationalist theory through Wudt and his colleagues’ studies on sensation and perception (McGuire, n.d). In this instance, the understanding of psychology was very much a cognitive one – later to be known as structuralism because it focused on sensory and perceptual events related to it (McGuire, n.d). More introspections and innovations among psychologists led to behaviourism. Behaviourism was founded through the writings of John Watson who collected data on behaviour itself and how the organism acted. According to Watson, it is not enough to observe the mind (McGuire, n.d). It is important however to see human behaviour as a result of learning and he points out the teachings and the lessons learned by Ivan Pavlov in his experimentations. More studies on the infra-human species and the concepts of stimulus, response reinforcement, and extinction were also developed. This saw the introduction of BF Skinner’s work on operant conditioning (McGuire, n.d). The introduction of the behaviourist patterns of therapy did not stop the work of the cognitive therapists. Moreover, their work also focused on memory, perception, and related areas. Their analysis was not in any way related to behaviourists; and their research progressed well in relation to children.

Design Of A PV-Diesel Hybrid System

Design Of A PV-Diesel Hybrid System Design Of A PV-Diesel Hybrid System And Its Comparison With Grid Connected System In Pakistan 1. Project Background And Introduction Introduction The project with respect to this thesis is to design a PV Diesel hybrid system and to compare it with already existed grid connected system. This system is designed for a Jamia Masjid (Islamic center) in Pakpattan, Pakistan. The exact site of the project is a colony of Pakpattan which is in the south-west of the city Pakpattan. The Pakpattan city is situated around 161 Km south west to Lahore. The climate and weather data is almost same for Lahore and Pakpattan. Furthermore it will be first project of its own nature in this area and it will help to design the systems for the residential areas by which a common person can get benefits and get rid of power failures. Pakistan is located between latitude 24 and 37 degrees North and longitude 62 and 75 degrees East. Pakistan has Afghanistan in the north-west, Iran on west boarder, India is on the east, China in the north and the Arabian Sea is on the south. Pakistan is ageographical centre of the Asian Continent because it builds a type of bridge between Far East and Middle East; also it has a continental type of climate which can be characterized by extreme variations of temperature. Generally the climate of Pakistan is arid, means very high temperature in summer and low temperatures in winter. High altitudes change the climate in the freezing northern mountains which are covered with snow. There is little rainfall. There are some differences exist distinctly in various locations, e.g. the coastal line along Arabian Sea is usually under warm conditions, whereas the Karakoram mountain range and some other mountains of far north are so cold, completely frozen and covered with snow that these are only visible and accessible by some international world-class climbers for a couple of months of May and June of each year. The variation of daily temperature could be 11 0C to 17 0C but in winters the minimum mean temperature is about 4 0C in January. Pakistan has tremendous recourses of energy but unfortunately due to mismanagement out of 170 million population just 65-70% has access to electricity. Demand is more than supply of energy to residential and industrial sector. Currently Pakistan is facing 3000 MW of power storage and it is expected that in year 2010 the demand will exceed supply by 5500 MW. The current power and electricity demand and supply gap shows that there is a big need to increases the current power generation capacity in Pakistan. Aim Of The Thesis The main aim of the project is to explain the design phase of a single home PV system. The procedures and details of the design are presented with step by step. There are main following aims which are supposed to be fulfilled by this thesis. a) To go through and grab the core knowledge of the designing process. b) To get familiar with different tools used for designing and make selection between them. c) Beyond from bookish knowledge, get to know some real and practical aspects of different PV systems and projects. The body and structure of the thesis is mainly divided into four phases. a) Calculation of the primary load for this specific project with the help of PVSYST version 4 b) Division of the load to PV and Diesel Generator according to boundary conditions and design parameters. c) Economical and technical look on already existed grid connected system. d) Comparative study between this newly design system and already existed grid connected system in terms of economics, availability and life time World Energy Situation There are different factors which effect and play an important role in the consumption, demand and availability of energy, for example the consumption by individual user and business is being increased, everyday growing population and new government policies are some of these factors. But the fossil fuels are exhaustible. There are two aspects of the fossil fuels, 1st is their availability and 2nd is those harmful environmental impacts which appear after using and burning of these fossil fuels. It is equally harmful for the present generations as well as for future generations. But with the passage of time more and more people and governments are getting awareness about these impacts. The current energy demand projections can be seen from the facts and figures provided by World Energy Administration (EIA) â€Å"The total world energy consumption increases from 472 quadrillion Btu in 2006 to 552 quadrillion Btu in 2015 and 678 quadrillion Btu in 2030—a total increase of 44 percent over the projection period† Renewable Energy Situation Of The World When the first Renewable Global Status Report was published in 2004, many indicators have shown dramatic gains. In the last four years from the end of 2004 to the end of 2008, solar photovoltaic capacity increased six times which is more than 16 gigawatts (GW). Wind power capacity has been increased 250 percent to 121 GW; the total power capacity from new renewable recourses has been increased 75 percent to 280 GW which includes significant gains in small geothermal, hydro, and biomass power generation. During the same period of time, solar heating capacity become double to 145 gigawatts-thermal, while the biodiesel production has been also increased six times to 12 billion liters per year and ethanol production doubled to 67 billion liters per year. The annual percentage gain for the year 2008 was also very amazing and more dramatic. The growth in Wind energy was 29% and grid connected solar PV by 70%. The capacity of utility scale PV plants also increased during this period. Solar hot water systems also grew by 15%. All around the world the governments are changing the policies about the future energy crises and energy markets and policy. In this race the United States of America became the leader and invested $24 billion for new capacity which is 20% of the total global investment. The United States is also leading in adding the total wind energy capacity and also surpassed Germany who was a wind power leader for a long time. Spain has added around 2.6 GW of solar PV, which is a full half of grid connected installations all around the global and five times increase over Spains 2007 additions. China has doubled its capacity to produce wind energy and now ranked at fourth place all around the world. Another significant and important milestone was that the European Union and the USA added more capacity to produce power from renewable recourses than from conventional energy sources (as gas, oil, coal and nuclear) and it happened for the first time. The industries of Renewable energy boomed mostly during 2008. Global solar PV production was increased by 90% to 6.9 GW in 2008. Energy Profile Of Pakistan The energy profile of Pakistan is inadequate and there are always short falls of energy (electricity) especially during summer. Pakistan needs around 14,000 to 15,000 MW electricity everyday to meet all residential and industrial demands. But Pakistan can produce around 11,500 MW, so it means there is around 3000 MW to 4000 MW short fall. This shortfall was experienced extensively and on its peak this year and affecting industry, commerce and daily life. During this year the shortfall for electricity in rural areas was around 12 to 16 hours and in urban areas it was about 8 to 12 hours. The reasons for this deficiency are limited fossil fuel resources, weak economy and mismanagement of the available energy sources. There are some commercial sources of energy available in Pakistan, they are: Hydro energy; Nuclear energy; Oil and gas; Conventional fuels like agricultural wastes, animal dung and wood fuel. Here, it is an overview of primary energy supplies in Pakistan in MTOE (TOE: ton of oil equivalent. It is an energy unit which is equal to the energy of burning of 1 ton of crude oil which is about 42 GJ) From fig 1.3 it is clear that energy supply of Pakistan is highly dependent on Oil and Gas. Both Oil and Gas contribute more than 79% of total primary energy supplied. The other sources of energy like hydro- electricity, coal, nuclear electricity and imported electricity contribute about 21% of the total share. As energy is essential for all types of production processes. Pakistan has been growing in agricultural and industrial sector during last decade and thats why energy demand is being increased. As population and industry is growing, the daily demand will increase up to 20,000 MW in 2010. Pakistan meets around 75% of its energy needs by oil, gas and hydro electricity production. Natural gas has played an important role to meet the energy needs in recent years. But Pakistan needs to expand its energy resource on permanent bases. In order to overcome this energy shortage, Pakistan needs to expand and develop its indigenous energy resources such as hydropower, wind and solar energy. Pakistan is one of the highest solar insulation areas of the world. Now we will briefly discuss the main energy sources in Pakistan. Natural Gas After the independence of Pakistan in 1952 Sui natural gas field resources in Baluchistan were discovered first time. The production at Sui started in 1955 and was on its peak in 1985. It was the most productive gas field of Pakistan in early 1990s. In FY 1993 it was accounting 46% of production. After that the second largest gas field was discovered which is also located in Baluchistan at Mari, which was contributing 20% of all production. Total 25 gas fields were fully operational in FY 1993. The estimation of recoverable natural gas reserves were estimated around 662.0 billion cubic meters, with an extraction rate around 14.0 billion cubic meters. In order to meet the increasing demand of energy and for future planning, efforts from government are being made to increase the production of gas in the country. To do this exploration activities are the first step. The estimation of recoverable reserves of natural gas was 29.671 trillion cubic feet in January 2009. During July-March 2008-2009 the average production of natural gas was 3986.5 mmcfd (million cubic feet per day) but during the corresponding period of last year it was around 3965.9 mmcfd which shows an increase of around 0.52%. At the moment 26 public and private sector companies are engaged in exploration and production activities of oil and gas in Pakistan. LPG The contribution of LPG (Liquefied Petroleum Gas) is about 0.7% to the total energy supply of Pakistan. LPG is being supplied to many remote areas where the supply of natural gas is not technically suitable. To do this government has changed policies for energy supply and management and as a result of this modification the supply of LPG in 2007-2008 was 601,592 Metric Ton and in last few years the annual cumulative growth rate was 18.2%.years. Around 32,621 MT of LPG was imported during July-March, 2009. CNG The main reason of encouragement of Compressed Natural Gas (CNG) use is to improve environment and to decrease the dependency on other fuels. The price difference between petrol and CNG is about 60.0 percent, thats why vehicles are being converted to CNG day by day and around 2.0 Million vehicles are using CNG. The numbers of CNG stations are also increasing day by day and there are around 2,700 established CNG stations in Pakistan which covers an investment of Rs.70 billion. At present Pakistan is the largest CNG user country. Oil The estimation of recoverable reserves of crude oil in total in Pakistan were around 313 million barrels in January 2009. The average production of crude oil during July-March 2008-09 was 66532 barrels per day. The average production of crude oil during last year was 70166 barrels per day which shows a negative growth of 5.2 percent. The average production of oil in Pakistan remained 67,438 BOPD in 2006-2007. Oil and gas development company and limited (OGDCL) was the biggest oil producing company in Pakistan with a production of around 13.261 million barrels which contribute around 54% of the total oil production per year of Pakistan with an average rate of 36,332 BOPD. After that British Petroleum (BP) is the second largest oil producing company with total contribution of 16% of total oil production in Pakistan. BP produces around 4.025 million barrels averagely with 11,029 BOPD. Pakistan oil fields limited (POL) produced around 3.231 million barrels. There are other small oil production companies as well in Pakistan. Coal The total estimation of coal recourses of Pakistan is more than 185 billion tones. Thar coalfield (Sindh province) is the biggest coal source which worth more than 175 billion tones. Pakistans coal is generally ranked from lignite to sub bituminous. The production of coal was decreased in during July-March 2008-09 by 28.8%. About 60.4% of the total coal production is being consumed by the brick kilns industry. Cement industry is also using a large fraction of coal which is around 37.4% and almost all cement industry is being switched on coal from furnace oil. As energy demand is increasing day by day and government is reshaping the energy policies. Due to high prices of imported energy government of Pakistan has decided to increase the share of coal from 05 to 19% in the overall energy mix up to 2030. In view of expected shortfall of energy resources and electricity during the next 10 years the maximum utilization of coal would be needed for power generation and gasification. Accordi ng to government energy security plan, a target has been set which is to generate about 20,000 MW power from coal by 2030 and 50% by 2050. Nuclear Energy: Pakistan is the 7th nuclear power of the world. In 2009, the nuclear power plants contribute up to 2.4% share to the total electricity production in Pakistan. Pakistan has two working nuclear reactors which produce about 425 MW power for the generation of electricity. The third nuclear reactor will be operational in spring of 2010. In Pakistan nuclear power contributes very small to the electricity production. The total generating capacity is around 20 GWe while in 2006; 98 billion kWh gross was generated. First nuclear power reactor was started in 1971 in KANUPP near Karachi and it has small capacity of 125 MWe and it is pressurized heavy water reactor (PHWR). The second unit was started in May 2000 and is known as Chashma-1 in Punjab. It has capacity of 325 MWe. It is pressurized water reactor (PWR) and was supplied by Chinas CNNC under safeguards. It is also known as CHASNUPP-1. In December 2005 construction of its twin Chashma-2 was started. It is reported that it cost PKR 51.46 billion (US$ 860 million, $350 million were financed by China). But these sources are not sufficient to overcome this energy crises and Pakistan needs to develop renewable energy sources. Renewable Energy Sources In Pakistan Pakistan is situated in such a special geographic location that it is blessed with abundant and inexhaustible Renewable Energy (RE) resources. These resources can play an effective and considerable role for the contribution towards energy security of Pakistan. When we look into current world energy scenario in general and energy scenario of Pakistan in particular, the development and adoption of RE technologies makes better sense. Government policies and objectives to develop RE technology are also matching with this sense so that the share of RE in overall energy mix should be at least 5% by the year 2030. Wind potential: 0. 346 Million MW Solar potential: 2.9 Million MW Mini Small Hydel: 2,000 MW [9] There is a significant potential of wind energy in Pakistan especially in the coastal belt of Baluchistan and Sindh, and also in the desert areas of Punjab and Sindh. However this renewable energy source has not been utilized. AEDB collected the wind data of all Pakistan from Pakistan Metrological Department and was analyzed. On the basis of this collected data and analysis, it was stated that the coastal belt of Pakistan has a God gifted 60 km wide (Gharo-Keti Bandar) and 180 km long (up to Hyderabad) wind corridor. This wind corridor has the potential to generate 50,000 MW of electricity. AEDB has done other different surveys in Gharo and Jhimpir regions and some coastal area of Baluchistan. After these surveys it is concluded that in the south region most of the remote villages can be easily electrified through micro wind turbines. Furthermore it is estimated that in Baluchistan Sindh and Northern areas more than 5000 villages can be electrified through wind energy. Sincere efforts and aggressive lobbying has been done by AEDB with national and international investors to invest and to make them realize the tremendous potentials of RE. AEBD is in negotiations with international companies to set up their business in Pakistan. However large wind mills have not been installed yet but 30 wind mills for water pumping have been installed on experimental basis in different parts of Baluchistan and Sindh. In southern coastal areas of Pakistan remote villages are currently electrified with energy and so far more than 17 villages have been electrified using micro wind turbines. Around 95% of total electricity generation is from hydropower in Pakistan. But during summer in hottest and driest months of the year it becomes less productive and cannot meet the energy demands. Also, around 70% of the population lives in 50,000 villages. Many of these villages are very far from the main transmission lines and also it is not economically viable to connect these small villages to the main grid due to their small population. On the other hand solar energy has excellent and significant potential. Pakistan is one of those countries which receive solar radiations at high level throughout the year. Every day it receives an average of about 19 MJ/m2 of solar energy. Studies have been already done and solar systems have been developed and tested. There is a list of different projects which are completed by Pakistan council of Renewable energy technology. Potential Of PV In Pakistan The location of Pakistan is very ideal to take advantage of solar energy as a source of energy because Pakistan is in the Sun Belt region. Solar energy is available abundantly and widely distributed all around the country. Following figure shows solar insolation map for Pakistan. The map shows around 200-250 W/m2 per day. The Baluchistan province is very rich in solar energy. It receives around 19-20 MJ/m2 per day averagely which is equal to 1.93-2.03 MWh/ m2 per day with annual 8-8.5 mean annual sunshine hours. These conditions are ideal for PV and solar energy applications. Solar energy is very good option for off-grid villages. There are around 75,000 off-grid villages which contains 4 million homes and every home accommodates around 4-5 people. These off-grid villages are situated in the Baluchistan and Frontier Province. AEDB has set a target to electrify a thousand villages via solar technology by the year 2010. In this respect the first contract has been given to the Sehgal electronics group (Pakistan). Each home which is electrified with PV will have around 400 W power supply and lead acid batteries for overnight storage. There are also other plans to have local production using PV modules with and estimation of this production is around 3MW/year. Possible Routes For Solar PV In Pakistan The global demand of PV equipment is increasing day by day and due to this fact the prices for PV systems, equipment and electricity has gone down remarkably. PV could be exploited in Pakistan through following two routes. Off-grid Or Stand-Alone Sector Stand-alone systems generate electricity independently of the utility grid. Stand alone systems can be a very good option for the remote areas and very deep located villages, where the extension of power transmission lines would be more costly. Also it could be implemented in environmentally sensitive areas as parks, remote homes and cabins. In rural areas, it could be used for solar water pumps and farm lighting. [12] Grid-Connected Sector Grid-connected PV systems supply extra power when the home systems power supply is not sufficient to fulfill the load. These systems remove the need of battery bank. In some situation, utilities allow net metering, by which the owner can sell extra power back to the utility. Current Solar Energy Applications In Pakistan Both PV and solar thermal have a wide range of applications in Pakistan. Although the scale of utilization and adoption has been very small but it has been utilized for last 25 years in Pakistan. Different applications mainly PV and solar thermal applications are summarized as. Photovoltaics Eighteen PV stations were built by the government in the early 1980s to electrify different villages the country. The installed capacity was nearly 440 kW but due to the lack of technical knowledge and follow up, these systems could not perform as required. Currently in Pakistan solar energy is being used for telephone exchanges stand alone rural electrification, cathodic protection, highway emergency telephones and vaccine refrigeration in hospitals. In different parts of Baluchistan, about 20 solar water pumps have been installed for drinking purposes by The Public Health Department. The northern and western area of Pakistan are mostly hilly and mountain areas (Hindu Kush-Himalayas, HKH region), which are blessed with a lot of sunshine with 4-6 kWh/m2 daily average solar radiation. Seven solar stations were installed in this region in the late 1980s for lighting by different companies. The total capacity of these systems was 234 kW. They are not in operation now due maintenance pro blems. SIEMENS Pakistan has installed many stand alone solar systems in Pakistan. On the Lahore-Islamabad Motorway, it has installed power supply systems for many microwave-link repeater stations and more than 350 emergency call boxes. Solar Thermal Applications There are many applications which utilize solar energy directly by utilizing its heat characteristics. Such applications are much simple, low cost and easy to adopt. The applications include heating and cooling of homes and buildings, cooking, water heating for domestic and industrial use and drying agricultural products. A brief description of such applications in Pakistan is given here. Solar Water Heaters This technology is quite mature in Pakistan but very limited because of its higher capital cost as compared to conventional water heaters which operate on natural gas. But in last couple of years it has started to gain popularity because a number of public sector organizations are working to develop low cost solar water heaters. The prices of natural gas and electricity are increasing day by day, so people are adopting solar water heaters and also private sector has already started the production of such heaters. Solar Cooker Different public sector organizations have been working to develop low cost and efficient design solar cookers. In HKH region of Pakistan, more than 2000 solar cookers are in use. This number is very small. It needs to be more popularized. Pakistan needs to reduce the use of precious forest resources as fuel wood and to replace it with solar cookers. Solar Dryers Solar energy can be very good option for drying agriculture products. By this, we can get very good quality products at much less cost. Northern mountainous areas like Gilgit and Sakardu are very rich in fruit production like apricots which used to be wasted by tons every year. But now solar dryers are being used to dry large quantities of fruit, which is leaving a positive effect on the economy of this area. Different NGOs are working for the popularizing and the use of such dryers. Solar Desalination Drinkable water is unavailable in many parts of Sindh, Baluchistan and southern Punjab and it is very critical issue. Underground water is available but it is highly saline. This saline water is not fit for drinking at all and causes many dangerous diseases such as hypertension. Solar energy can be utilized to convert this available saline water into drinkable water. Solar desalination is very simple, low cost and easy to use. Also it is very easy to adopt. A successful solar desalination project is in operation and it is working very fine and helping to change the life style of the population of Gawader in the Baluchistan province. It consists of 240 stills and each can clean 6000 gallons of seawater per day. 2. Basics And Components Of A PV System Basics Of A PV System Photovoltaic is the technology which converts solar energy directly into electricity and this process is carried out though solar cells. Solar cell is a device which converts sun energy into electricity. We can say solar cell as photovoltaic cell as well but solar cell term will be used when the source of light is defined as â€Å"sun† but if it is not defined than we can say it as photovoltaic cell. Now days when entire world is looking for a neat and clean environment and want to meet huge energy requirements without disturbing and populating the environment, sustainable energy sources seems to play their important role. Researchers and scientists from all around the world are looking for these types of renewable sources. They are trying to get the energy needs from these renewable energy sources. The main advantages of using renewable energy sources are 1. Neat and clean environment 2. Yield of energy is higher 3. Safer for electricity production as compared to convention methods (low voltage) 4. Long life times 5. Low maintenance cost 6. Use of natural sources which are being wasted with time. These are the reason, why people prefer renewable energy sources. There are different types of renewable energy sources as 1. Solar energy 2. Wind energy 3. Tidal energy 4. Geothermal energy 5. Wave power 6. Hydropower 7. Bio energy We will discuss solar energy in detail and its related topics in this report. There are different units in a PV system and all these units combine to make a full working PV system. These are PV System Components 1. PV Panels 2. Trackers and tracking system 3. Array DC Disconnect 4. Blocking diodes 5. Charge Controller 6. Battery Bank 7. System Meter 8. Main DC Disconnect 9. Inverter 10. Kilowatt-Hour Meter 11. Backup Generator PV Panels PV panels are the defining components of a PV system, which uses sunlight to make direct current (DC) electricity. Wafers of semiconductor material are used for this purpose. They use light (photons) to produce electricity (photovoltaic effect). When the electricity is generated than it powers our electric loads such as lights, computers, and refrigerators. PV panels differ from each other on the basis of power rating in watts which is based on their maximum power generation capacity. Solar cell is the fundamental and basic building block in a PV system which acts as power conversion unit of this system. There are different types of solar cells now days available having different power about 1 or 2 watts. Usually solar cells are made of single crystal silicon and they are limited to about 25% efficiency. The reason is that they are most sensitive to IRL (infrared light), and the radiations in this region of electromagnetic spectrum are relatively low in energy. Another type of solar cells is Polycrystalline solar cells. They are made by a special casting process. In this process molten silicon is being poured into a mould, allowed to cool down and then it is sliced into wafers. By this process we can make relatively cheaper cells as compared to single crystal cells, but their efficiency is less than 20%. The reason is that there is internal resistance on the boundaries of silicon crystals which affects the efficiency. The third type of solar cells is amorphous cells and they are made by a special process in which silicon is deposited onto a glass substrate from a reactive gas such as silane (SiH4). These types of solar cells are used in solar powered watches and calculators, but now days bigger modules are also manufactured. They are also rather cheap and their efficiency is only up to 10%. The reason is, since amorphous silicon cell has no crystal structure and there are much internal energy losses. Solar cells are not just restricted to semiconductor materials; solar cells are available now days which convert sun light into electricity by organic molecules. Their efficiency is up to 10%. Apart from various types of silicon, other materials can also be used to make solar cells like cadmium telluride and gallium arsenide. There are different types of cell packings. The most common are raw cells, and they are often with cover sheet. Now we have discussed solar cells. These solar are combined together to make a module to get boosted power for practical purposes. Than these modules are combined together to make a panel, these panels are joined together to form a big array. Trackers And Tracking System Solar tracker is a device on which solar panels are fitted and the motion of the sun is tracked through this device. It ensures that the maximum amount of sunlight will strike to the panel throughout the whole day. Actually it is a mounting rack which follows the sun constantly. By using trackers, we can utilize maximum sunlight and thus can produce more electricity. In the morning time, it is low on eastern horizon while at the sunset it is low at western horizon. But at noon the position of sun is very high in the sky. This motion is due to the rotation of earth. Trackers keep PV modules perpendicular to incoming sun radiations and maximize the energy production. The increment in the energy production using trackers depends on the site and the type of tracker. Usually energy production increases 25 to 40% annually, which is shown in more detail in the following figure. To get maximum efficiency tracker must be placed in a suitable location. A good tracker site is that on which sun can be seen very early in the morning time and receive sunlight until sunset. There should be no solar obstructions like trees and buildings on the site or near the site in order to work perfectly. Before considering the tracker into system design, an evaluation of the site is done using Solar Pathfinder. Trackers are usually mounted on ground and use a heavy steel pole which is sunk into a concrete foundation. There are some systems where the trackers are mounted on the roofs, but it can create structural problems. There are two basic types of trackers. 1. Electrically operated 2. Thermally operated Thermally Operated Trackers These trackers are based on mass transfer from one side to the other side of the tracker to track the sun. This transfer of mass causes the tracker to turn from east to west by following the sun. Actually two tubes filled with Freon (which vaporizes and become gas) are mounted on east and west sides of the tracker. With the sunlight, the temperature of Freon becomes higher on one side of tracker, it starts to become vapors. These vapors take more space than as compared to the liquid Freon, which pushes Freon (liquid) to the other side. This transfer of mass from the one side to the other side of the tracker causes the change in the balance of tracker which eventually rotates it to the west. Usually they are slow Design Of A PV-Diesel Hybrid System Design Of A PV-Diesel Hybrid System Design Of A PV-Diesel Hybrid System And Its Comparison With Grid Connected System In Pakistan 1. Project Background And Introduction Introduction The project with respect to this thesis is to design a PV Diesel hybrid system and to compare it with already existed grid connected system. This system is designed for a Jamia Masjid (Islamic center) in Pakpattan, Pakistan. The exact site of the project is a colony of Pakpattan which is in the south-west of the city Pakpattan. The Pakpattan city is situated around 161 Km south west to Lahore. The climate and weather data is almost same for Lahore and Pakpattan. Furthermore it will be first project of its own nature in this area and it will help to design the systems for the residential areas by which a common person can get benefits and get rid of power failures. Pakistan is located between latitude 24 and 37 degrees North and longitude 62 and 75 degrees East. Pakistan has Afghanistan in the north-west, Iran on west boarder, India is on the east, China in the north and the Arabian Sea is on the south. Pakistan is ageographical centre of the Asian Continent because it builds a type of bridge between Far East and Middle East; also it has a continental type of climate which can be characterized by extreme variations of temperature. Generally the climate of Pakistan is arid, means very high temperature in summer and low temperatures in winter. High altitudes change the climate in the freezing northern mountains which are covered with snow. There is little rainfall. There are some differences exist distinctly in various locations, e.g. the coastal line along Arabian Sea is usually under warm conditions, whereas the Karakoram mountain range and some other mountains of far north are so cold, completely frozen and covered with snow that these are only visible and accessible by some international world-class climbers for a couple of months of May and June of each year. The variation of daily temperature could be 11 0C to 17 0C but in winters the minimum mean temperature is about 4 0C in January. Pakistan has tremendous recourses of energy but unfortunately due to mismanagement out of 170 million population just 65-70% has access to electricity. Demand is more than supply of energy to residential and industrial sector. Currently Pakistan is facing 3000 MW of power storage and it is expected that in year 2010 the demand will exceed supply by 5500 MW. The current power and electricity demand and supply gap shows that there is a big need to increases the current power generation capacity in Pakistan. Aim Of The Thesis The main aim of the project is to explain the design phase of a single home PV system. The procedures and details of the design are presented with step by step. There are main following aims which are supposed to be fulfilled by this thesis. a) To go through and grab the core knowledge of the designing process. b) To get familiar with different tools used for designing and make selection between them. c) Beyond from bookish knowledge, get to know some real and practical aspects of different PV systems and projects. The body and structure of the thesis is mainly divided into four phases. a) Calculation of the primary load for this specific project with the help of PVSYST version 4 b) Division of the load to PV and Diesel Generator according to boundary conditions and design parameters. c) Economical and technical look on already existed grid connected system. d) Comparative study between this newly design system and already existed grid connected system in terms of economics, availability and life time World Energy Situation There are different factors which effect and play an important role in the consumption, demand and availability of energy, for example the consumption by individual user and business is being increased, everyday growing population and new government policies are some of these factors. But the fossil fuels are exhaustible. There are two aspects of the fossil fuels, 1st is their availability and 2nd is those harmful environmental impacts which appear after using and burning of these fossil fuels. It is equally harmful for the present generations as well as for future generations. But with the passage of time more and more people and governments are getting awareness about these impacts. The current energy demand projections can be seen from the facts and figures provided by World Energy Administration (EIA) â€Å"The total world energy consumption increases from 472 quadrillion Btu in 2006 to 552 quadrillion Btu in 2015 and 678 quadrillion Btu in 2030—a total increase of 44 percent over the projection period† Renewable Energy Situation Of The World When the first Renewable Global Status Report was published in 2004, many indicators have shown dramatic gains. In the last four years from the end of 2004 to the end of 2008, solar photovoltaic capacity increased six times which is more than 16 gigawatts (GW). Wind power capacity has been increased 250 percent to 121 GW; the total power capacity from new renewable recourses has been increased 75 percent to 280 GW which includes significant gains in small geothermal, hydro, and biomass power generation. During the same period of time, solar heating capacity become double to 145 gigawatts-thermal, while the biodiesel production has been also increased six times to 12 billion liters per year and ethanol production doubled to 67 billion liters per year. The annual percentage gain for the year 2008 was also very amazing and more dramatic. The growth in Wind energy was 29% and grid connected solar PV by 70%. The capacity of utility scale PV plants also increased during this period. Solar hot water systems also grew by 15%. All around the world the governments are changing the policies about the future energy crises and energy markets and policy. In this race the United States of America became the leader and invested $24 billion for new capacity which is 20% of the total global investment. The United States is also leading in adding the total wind energy capacity and also surpassed Germany who was a wind power leader for a long time. Spain has added around 2.6 GW of solar PV, which is a full half of grid connected installations all around the global and five times increase over Spains 2007 additions. China has doubled its capacity to produce wind energy and now ranked at fourth place all around the world. Another significant and important milestone was that the European Union and the USA added more capacity to produce power from renewable recourses than from conventional energy sources (as gas, oil, coal and nuclear) and it happened for the first time. The industries of Renewable energy boomed mostly during 2008. Global solar PV production was increased by 90% to 6.9 GW in 2008. Energy Profile Of Pakistan The energy profile of Pakistan is inadequate and there are always short falls of energy (electricity) especially during summer. Pakistan needs around 14,000 to 15,000 MW electricity everyday to meet all residential and industrial demands. But Pakistan can produce around 11,500 MW, so it means there is around 3000 MW to 4000 MW short fall. This shortfall was experienced extensively and on its peak this year and affecting industry, commerce and daily life. During this year the shortfall for electricity in rural areas was around 12 to 16 hours and in urban areas it was about 8 to 12 hours. The reasons for this deficiency are limited fossil fuel resources, weak economy and mismanagement of the available energy sources. There are some commercial sources of energy available in Pakistan, they are: Hydro energy; Nuclear energy; Oil and gas; Conventional fuels like agricultural wastes, animal dung and wood fuel. Here, it is an overview of primary energy supplies in Pakistan in MTOE (TOE: ton of oil equivalent. It is an energy unit which is equal to the energy of burning of 1 ton of crude oil which is about 42 GJ) From fig 1.3 it is clear that energy supply of Pakistan is highly dependent on Oil and Gas. Both Oil and Gas contribute more than 79% of total primary energy supplied. The other sources of energy like hydro- electricity, coal, nuclear electricity and imported electricity contribute about 21% of the total share. As energy is essential for all types of production processes. Pakistan has been growing in agricultural and industrial sector during last decade and thats why energy demand is being increased. As population and industry is growing, the daily demand will increase up to 20,000 MW in 2010. Pakistan meets around 75% of its energy needs by oil, gas and hydro electricity production. Natural gas has played an important role to meet the energy needs in recent years. But Pakistan needs to expand its energy resource on permanent bases. In order to overcome this energy shortage, Pakistan needs to expand and develop its indigenous energy resources such as hydropower, wind and solar energy. Pakistan is one of the highest solar insulation areas of the world. Now we will briefly discuss the main energy sources in Pakistan. Natural Gas After the independence of Pakistan in 1952 Sui natural gas field resources in Baluchistan were discovered first time. The production at Sui started in 1955 and was on its peak in 1985. It was the most productive gas field of Pakistan in early 1990s. In FY 1993 it was accounting 46% of production. After that the second largest gas field was discovered which is also located in Baluchistan at Mari, which was contributing 20% of all production. Total 25 gas fields were fully operational in FY 1993. The estimation of recoverable natural gas reserves were estimated around 662.0 billion cubic meters, with an extraction rate around 14.0 billion cubic meters. In order to meet the increasing demand of energy and for future planning, efforts from government are being made to increase the production of gas in the country. To do this exploration activities are the first step. The estimation of recoverable reserves of natural gas was 29.671 trillion cubic feet in January 2009. During July-March 2008-2009 the average production of natural gas was 3986.5 mmcfd (million cubic feet per day) but during the corresponding period of last year it was around 3965.9 mmcfd which shows an increase of around 0.52%. At the moment 26 public and private sector companies are engaged in exploration and production activities of oil and gas in Pakistan. LPG The contribution of LPG (Liquefied Petroleum Gas) is about 0.7% to the total energy supply of Pakistan. LPG is being supplied to many remote areas where the supply of natural gas is not technically suitable. To do this government has changed policies for energy supply and management and as a result of this modification the supply of LPG in 2007-2008 was 601,592 Metric Ton and in last few years the annual cumulative growth rate was 18.2%.years. Around 32,621 MT of LPG was imported during July-March, 2009. CNG The main reason of encouragement of Compressed Natural Gas (CNG) use is to improve environment and to decrease the dependency on other fuels. The price difference between petrol and CNG is about 60.0 percent, thats why vehicles are being converted to CNG day by day and around 2.0 Million vehicles are using CNG. The numbers of CNG stations are also increasing day by day and there are around 2,700 established CNG stations in Pakistan which covers an investment of Rs.70 billion. At present Pakistan is the largest CNG user country. Oil The estimation of recoverable reserves of crude oil in total in Pakistan were around 313 million barrels in January 2009. The average production of crude oil during July-March 2008-09 was 66532 barrels per day. The average production of crude oil during last year was 70166 barrels per day which shows a negative growth of 5.2 percent. The average production of oil in Pakistan remained 67,438 BOPD in 2006-2007. Oil and gas development company and limited (OGDCL) was the biggest oil producing company in Pakistan with a production of around 13.261 million barrels which contribute around 54% of the total oil production per year of Pakistan with an average rate of 36,332 BOPD. After that British Petroleum (BP) is the second largest oil producing company with total contribution of 16% of total oil production in Pakistan. BP produces around 4.025 million barrels averagely with 11,029 BOPD. Pakistan oil fields limited (POL) produced around 3.231 million barrels. There are other small oil production companies as well in Pakistan. Coal The total estimation of coal recourses of Pakistan is more than 185 billion tones. Thar coalfield (Sindh province) is the biggest coal source which worth more than 175 billion tones. Pakistans coal is generally ranked from lignite to sub bituminous. The production of coal was decreased in during July-March 2008-09 by 28.8%. About 60.4% of the total coal production is being consumed by the brick kilns industry. Cement industry is also using a large fraction of coal which is around 37.4% and almost all cement industry is being switched on coal from furnace oil. As energy demand is increasing day by day and government is reshaping the energy policies. Due to high prices of imported energy government of Pakistan has decided to increase the share of coal from 05 to 19% in the overall energy mix up to 2030. In view of expected shortfall of energy resources and electricity during the next 10 years the maximum utilization of coal would be needed for power generation and gasification. Accordi ng to government energy security plan, a target has been set which is to generate about 20,000 MW power from coal by 2030 and 50% by 2050. Nuclear Energy: Pakistan is the 7th nuclear power of the world. In 2009, the nuclear power plants contribute up to 2.4% share to the total electricity production in Pakistan. Pakistan has two working nuclear reactors which produce about 425 MW power for the generation of electricity. The third nuclear reactor will be operational in spring of 2010. In Pakistan nuclear power contributes very small to the electricity production. The total generating capacity is around 20 GWe while in 2006; 98 billion kWh gross was generated. First nuclear power reactor was started in 1971 in KANUPP near Karachi and it has small capacity of 125 MWe and it is pressurized heavy water reactor (PHWR). The second unit was started in May 2000 and is known as Chashma-1 in Punjab. It has capacity of 325 MWe. It is pressurized water reactor (PWR) and was supplied by Chinas CNNC under safeguards. It is also known as CHASNUPP-1. In December 2005 construction of its twin Chashma-2 was started. It is reported that it cost PKR 51.46 billion (US$ 860 million, $350 million were financed by China). But these sources are not sufficient to overcome this energy crises and Pakistan needs to develop renewable energy sources. Renewable Energy Sources In Pakistan Pakistan is situated in such a special geographic location that it is blessed with abundant and inexhaustible Renewable Energy (RE) resources. These resources can play an effective and considerable role for the contribution towards energy security of Pakistan. When we look into current world energy scenario in general and energy scenario of Pakistan in particular, the development and adoption of RE technologies makes better sense. Government policies and objectives to develop RE technology are also matching with this sense so that the share of RE in overall energy mix should be at least 5% by the year 2030. Wind potential: 0. 346 Million MW Solar potential: 2.9 Million MW Mini Small Hydel: 2,000 MW [9] There is a significant potential of wind energy in Pakistan especially in the coastal belt of Baluchistan and Sindh, and also in the desert areas of Punjab and Sindh. However this renewable energy source has not been utilized. AEDB collected the wind data of all Pakistan from Pakistan Metrological Department and was analyzed. On the basis of this collected data and analysis, it was stated that the coastal belt of Pakistan has a God gifted 60 km wide (Gharo-Keti Bandar) and 180 km long (up to Hyderabad) wind corridor. This wind corridor has the potential to generate 50,000 MW of electricity. AEDB has done other different surveys in Gharo and Jhimpir regions and some coastal area of Baluchistan. After these surveys it is concluded that in the south region most of the remote villages can be easily electrified through micro wind turbines. Furthermore it is estimated that in Baluchistan Sindh and Northern areas more than 5000 villages can be electrified through wind energy. Sincere efforts and aggressive lobbying has been done by AEDB with national and international investors to invest and to make them realize the tremendous potentials of RE. AEBD is in negotiations with international companies to set up their business in Pakistan. However large wind mills have not been installed yet but 30 wind mills for water pumping have been installed on experimental basis in different parts of Baluchistan and Sindh. In southern coastal areas of Pakistan remote villages are currently electrified with energy and so far more than 17 villages have been electrified using micro wind turbines. Around 95% of total electricity generation is from hydropower in Pakistan. But during summer in hottest and driest months of the year it becomes less productive and cannot meet the energy demands. Also, around 70% of the population lives in 50,000 villages. Many of these villages are very far from the main transmission lines and also it is not economically viable to connect these small villages to the main grid due to their small population. On the other hand solar energy has excellent and significant potential. Pakistan is one of those countries which receive solar radiations at high level throughout the year. Every day it receives an average of about 19 MJ/m2 of solar energy. Studies have been already done and solar systems have been developed and tested. There is a list of different projects which are completed by Pakistan council of Renewable energy technology. Potential Of PV In Pakistan The location of Pakistan is very ideal to take advantage of solar energy as a source of energy because Pakistan is in the Sun Belt region. Solar energy is available abundantly and widely distributed all around the country. Following figure shows solar insolation map for Pakistan. The map shows around 200-250 W/m2 per day. The Baluchistan province is very rich in solar energy. It receives around 19-20 MJ/m2 per day averagely which is equal to 1.93-2.03 MWh/ m2 per day with annual 8-8.5 mean annual sunshine hours. These conditions are ideal for PV and solar energy applications. Solar energy is very good option for off-grid villages. There are around 75,000 off-grid villages which contains 4 million homes and every home accommodates around 4-5 people. These off-grid villages are situated in the Baluchistan and Frontier Province. AEDB has set a target to electrify a thousand villages via solar technology by the year 2010. In this respect the first contract has been given to the Sehgal electronics group (Pakistan). Each home which is electrified with PV will have around 400 W power supply and lead acid batteries for overnight storage. There are also other plans to have local production using PV modules with and estimation of this production is around 3MW/year. Possible Routes For Solar PV In Pakistan The global demand of PV equipment is increasing day by day and due to this fact the prices for PV systems, equipment and electricity has gone down remarkably. PV could be exploited in Pakistan through following two routes. Off-grid Or Stand-Alone Sector Stand-alone systems generate electricity independently of the utility grid. Stand alone systems can be a very good option for the remote areas and very deep located villages, where the extension of power transmission lines would be more costly. Also it could be implemented in environmentally sensitive areas as parks, remote homes and cabins. In rural areas, it could be used for solar water pumps and farm lighting. [12] Grid-Connected Sector Grid-connected PV systems supply extra power when the home systems power supply is not sufficient to fulfill the load. These systems remove the need of battery bank. In some situation, utilities allow net metering, by which the owner can sell extra power back to the utility. Current Solar Energy Applications In Pakistan Both PV and solar thermal have a wide range of applications in Pakistan. Although the scale of utilization and adoption has been very small but it has been utilized for last 25 years in Pakistan. Different applications mainly PV and solar thermal applications are summarized as. Photovoltaics Eighteen PV stations were built by the government in the early 1980s to electrify different villages the country. The installed capacity was nearly 440 kW but due to the lack of technical knowledge and follow up, these systems could not perform as required. Currently in Pakistan solar energy is being used for telephone exchanges stand alone rural electrification, cathodic protection, highway emergency telephones and vaccine refrigeration in hospitals. In different parts of Baluchistan, about 20 solar water pumps have been installed for drinking purposes by The Public Health Department. The northern and western area of Pakistan are mostly hilly and mountain areas (Hindu Kush-Himalayas, HKH region), which are blessed with a lot of sunshine with 4-6 kWh/m2 daily average solar radiation. Seven solar stations were installed in this region in the late 1980s for lighting by different companies. The total capacity of these systems was 234 kW. They are not in operation now due maintenance pro blems. SIEMENS Pakistan has installed many stand alone solar systems in Pakistan. On the Lahore-Islamabad Motorway, it has installed power supply systems for many microwave-link repeater stations and more than 350 emergency call boxes. Solar Thermal Applications There are many applications which utilize solar energy directly by utilizing its heat characteristics. Such applications are much simple, low cost and easy to adopt. The applications include heating and cooling of homes and buildings, cooking, water heating for domestic and industrial use and drying agricultural products. A brief description of such applications in Pakistan is given here. Solar Water Heaters This technology is quite mature in Pakistan but very limited because of its higher capital cost as compared to conventional water heaters which operate on natural gas. But in last couple of years it has started to gain popularity because a number of public sector organizations are working to develop low cost solar water heaters. The prices of natural gas and electricity are increasing day by day, so people are adopting solar water heaters and also private sector has already started the production of such heaters. Solar Cooker Different public sector organizations have been working to develop low cost and efficient design solar cookers. In HKH region of Pakistan, more than 2000 solar cookers are in use. This number is very small. It needs to be more popularized. Pakistan needs to reduce the use of precious forest resources as fuel wood and to replace it with solar cookers. Solar Dryers Solar energy can be very good option for drying agriculture products. By this, we can get very good quality products at much less cost. Northern mountainous areas like Gilgit and Sakardu are very rich in fruit production like apricots which used to be wasted by tons every year. But now solar dryers are being used to dry large quantities of fruit, which is leaving a positive effect on the economy of this area. Different NGOs are working for the popularizing and the use of such dryers. Solar Desalination Drinkable water is unavailable in many parts of Sindh, Baluchistan and southern Punjab and it is very critical issue. Underground water is available but it is highly saline. This saline water is not fit for drinking at all and causes many dangerous diseases such as hypertension. Solar energy can be utilized to convert this available saline water into drinkable water. Solar desalination is very simple, low cost and easy to use. Also it is very easy to adopt. A successful solar desalination project is in operation and it is working very fine and helping to change the life style of the population of Gawader in the Baluchistan province. It consists of 240 stills and each can clean 6000 gallons of seawater per day. 2. Basics And Components Of A PV System Basics Of A PV System Photovoltaic is the technology which converts solar energy directly into electricity and this process is carried out though solar cells. Solar cell is a device which converts sun energy into electricity. We can say solar cell as photovoltaic cell as well but solar cell term will be used when the source of light is defined as â€Å"sun† but if it is not defined than we can say it as photovoltaic cell. Now days when entire world is looking for a neat and clean environment and want to meet huge energy requirements without disturbing and populating the environment, sustainable energy sources seems to play their important role. Researchers and scientists from all around the world are looking for these types of renewable sources. They are trying to get the energy needs from these renewable energy sources. The main advantages of using renewable energy sources are 1. Neat and clean environment 2. Yield of energy is higher 3. Safer for electricity production as compared to convention methods (low voltage) 4. Long life times 5. Low maintenance cost 6. Use of natural sources which are being wasted with time. These are the reason, why people prefer renewable energy sources. There are different types of renewable energy sources as 1. Solar energy 2. Wind energy 3. Tidal energy 4. Geothermal energy 5. Wave power 6. Hydropower 7. Bio energy We will discuss solar energy in detail and its related topics in this report. There are different units in a PV system and all these units combine to make a full working PV system. These are PV System Components 1. PV Panels 2. Trackers and tracking system 3. Array DC Disconnect 4. Blocking diodes 5. Charge Controller 6. Battery Bank 7. System Meter 8. Main DC Disconnect 9. Inverter 10. Kilowatt-Hour Meter 11. Backup Generator PV Panels PV panels are the defining components of a PV system, which uses sunlight to make direct current (DC) electricity. Wafers of semiconductor material are used for this purpose. They use light (photons) to produce electricity (photovoltaic effect). When the electricity is generated than it powers our electric loads such as lights, computers, and refrigerators. PV panels differ from each other on the basis of power rating in watts which is based on their maximum power generation capacity. Solar cell is the fundamental and basic building block in a PV system which acts as power conversion unit of this system. There are different types of solar cells now days available having different power about 1 or 2 watts. Usually solar cells are made of single crystal silicon and they are limited to about 25% efficiency. The reason is that they are most sensitive to IRL (infrared light), and the radiations in this region of electromagnetic spectrum are relatively low in energy. Another type of solar cells is Polycrystalline solar cells. They are made by a special casting process. In this process molten silicon is being poured into a mould, allowed to cool down and then it is sliced into wafers. By this process we can make relatively cheaper cells as compared to single crystal cells, but their efficiency is less than 20%. The reason is that there is internal resistance on the boundaries of silicon crystals which affects the efficiency. The third type of solar cells is amorphous cells and they are made by a special process in which silicon is deposited onto a glass substrate from a reactive gas such as silane (SiH4). These types of solar cells are used in solar powered watches and calculators, but now days bigger modules are also manufactured. They are also rather cheap and their efficiency is only up to 10%. The reason is, since amorphous silicon cell has no crystal structure and there are much internal energy losses. Solar cells are not just restricted to semiconductor materials; solar cells are available now days which convert sun light into electricity by organic molecules. Their efficiency is up to 10%. Apart from various types of silicon, other materials can also be used to make solar cells like cadmium telluride and gallium arsenide. There are different types of cell packings. The most common are raw cells, and they are often with cover sheet. Now we have discussed solar cells. These solar are combined together to make a module to get boosted power for practical purposes. Than these modules are combined together to make a panel, these panels are joined together to form a big array. Trackers And Tracking System Solar tracker is a device on which solar panels are fitted and the motion of the sun is tracked through this device. It ensures that the maximum amount of sunlight will strike to the panel throughout the whole day. Actually it is a mounting rack which follows the sun constantly. By using trackers, we can utilize maximum sunlight and thus can produce more electricity. In the morning time, it is low on eastern horizon while at the sunset it is low at western horizon. But at noon the position of sun is very high in the sky. This motion is due to the rotation of earth. Trackers keep PV modules perpendicular to incoming sun radiations and maximize the energy production. The increment in the energy production using trackers depends on the site and the type of tracker. Usually energy production increases 25 to 40% annually, which is shown in more detail in the following figure. To get maximum efficiency tracker must be placed in a suitable location. A good tracker site is that on which sun can be seen very early in the morning time and receive sunlight until sunset. There should be no solar obstructions like trees and buildings on the site or near the site in order to work perfectly. Before considering the tracker into system design, an evaluation of the site is done using Solar Pathfinder. Trackers are usually mounted on ground and use a heavy steel pole which is sunk into a concrete foundation. There are some systems where the trackers are mounted on the roofs, but it can create structural problems. There are two basic types of trackers. 1. Electrically operated 2. Thermally operated Thermally Operated Trackers These trackers are based on mass transfer from one side to the other side of the tracker to track the sun. This transfer of mass causes the tracker to turn from east to west by following the sun. Actually two tubes filled with Freon (which vaporizes and become gas) are mounted on east and west sides of the tracker. With the sunlight, the temperature of Freon becomes higher on one side of tracker, it starts to become vapors. These vapors take more space than as compared to the liquid Freon, which pushes Freon (liquid) to the other side. This transfer of mass from the one side to the other side of the tracker causes the change in the balance of tracker which eventually rotates it to the west. Usually they are slow

freedol Noras Freedom in Ibsens A Dolls House Essay -- Dolls House

Nora's Freedom in A Doll's House        Ã‚  Ã‚   Perhaps we have all felt the urge to "escape" to some tropical paradise. However, as individuals we have responsibilities and obligations to school, friends and family. These responsibilities and obligations usually keep us from "escaping". It is difficult to balance our personal need for freedom with our responsibility to others.   In Henrik Ibsen's play, A Doll's House, the character of Nora Helmer had suffered greatly to achieve her personal freedom.    A woman of the Victorian period, Nora Helmer was both a prisoner of her time as well as a pioneer. In her society women were viewed as a inferior to men and were not provided full legal rights. Women of that era were expected to stay at home and attend to the needs of their spouse and children. Nora was a free spirit just waiting to spread her wings; her husband Torvald would constantly disallow the slightest pleasures that she aspired to have, such as macaroons. (TEACHER COMMENT: THIS STATEMENT WOULD HAVE A BETTER EFFECT IF IT WERE DIRECTLY QUOTED FROM THE PLAY.)    Nora lived a life of lies in order to hold her marriage together. She kept herself pleased with little things such as telling Dr. Rank and Mrs. Linde, "I have such a huge desire to say-to hell and be damned" (Ibsen 59)! She did this just so she could release some tension that was probably building inside her due to all the restrictions that Torvald had set up, such as forbidding macaroons. The need for her to consume these macaroons behind her controlling husband's back was a way for her to satisfy her sense of needing to be an independent woman.    Upon the arrival of her old friend Kristine Linde, Nora took it upon herself to find her friend a job... ...ority says, or what's written in books. I have to think over these things myself and try to understand them (Ibsen 111).         In her leaving and the abandoning of her family and the memories that coincide with them, Nora was able to gain her freedom as an individual and was now in search for new responsibilities. We all have wanted to go out on our own and fulfill our responsibility to ourselves. However our need to find our individuality can lead to our downfall, or our success. In Ibsen's play, A Doll's House, an estranged wife, Nora Helmer; suffered to become an individual in her own right and took accountability for her actions to achieve her freedom.    Work Cited: Ibsen, Henrik.

Genetically- Modified Foods and Ingredients Essay

Visiting a supermarket has become a usual experience of each one of us. We have to read all the labels that warn us against genetically-modified ingredients and its expiry date. I, try myself to calm down that epidemic services take control over dangerous products. Yet, I have my doubts in eating my favorite snack, French fries that is done in a fast food. The cumulative effect of genetically-modified foods is particularly dangerous for sensitive populations, including kids, elderly people and people who have indigestion people and even us, whose normal healthy living people. I have studies literature on genetically-modified ingredients, trying to be objective in my judgment. Genetically-modified ingredients advance the modern biology achievements. These products and ingredients strengthen the resistance to herbicides and improve nutritional food contents. Genetically-modified (GM) foods production lessens time-consuming than conventional breeding. Molecular Biologists have not discovered yet how harmful GM products and ingredients are but they claim that GM foods may be environmentally hazardous. Only allergy was recognized as negative effect of GM foods. We, cannot break out from the GM products, since two-thirds of genetically modified crops are corn, cotton, soybeans, potatoes even the fruits we eat. This is just a sign that we should be well inform on what is going in our world especially in our foods that can affect our living. We cannot escape from this advancement in our modern world but we, people, can prevent this to have real healthy living life style.

Charles Lawrence on Racist Speech essays

Charles Lawrence on Racist Speech essays The voice of writers and authors are the key components to their inner thoughts. It is a way of actually portraying what a person is trying to say. However the case is that their words silenced and put in period of exile away from the eyes of the public. Author Charles Lawrence goes on to state that racist speech is wrong simply because of the drastic agony it puts on a victims perspective. In the article On Racist Speech, the author, Charles R Lawrence III, effectively establishes credibility, logic and emotional themes to supports his argument which infers that the use of harmful language should not be protected by the First Amendment Law in order to stop racism. Lawrence sheds light upon the very turbulent issue of the First Amendment right to the Freedom of speech in contrast to the inequality caused by its misuse through racially bias speech. The author states that the University officials should endorse some sort policy that will protect the rights of those who are victimized by this racial nuisance, while at the same time not censoring our constitutional right of free speech, I am troubled by the way the debates has been framed in response to the recent surge of racist incidents on college and university campuses and in response universities attempts to regulate harassing speech (51). Continually, Lawrence defines the set of ideals that the First Amendment was based on, particularly; equality. He goes on to show the audience that this very balance is in danger if the speech in question is stated in a deliberately hurtful manner. Lawrence brings up factual evidence from the Brown vs. Board of education that supports his claim that prejudice can also be viewed as a form of racist speech. Lawrence argues just as Brown did, that segregation in schools causes disparity and unfair conditions to the victims of racist speech. Brown deemed the idea of segregation as a symbo ...

What Caused the Defeat of the essays

What Caused the Defeat of the essays When looking at the Battle of the Little Big Horn there are many reasons why General Custer lost the battle. Many will say that he made bad choices and others will say that his luck just happened to run out that day. I think the reason why Custer lost the battle was a combination of both but it was his choices in the end that cost him his life and the battle. The events that went on around him that are considered his bad luck could have been looked at when they happened and fixed. There was a lot going on around Custer that could have made his mind not focused at the time of the battle such as running for president and also his ego along with overconfidence. From what Steven Ambrose put forth in his opinion of the battle I agree with most of the mistakes that he says Custer made. The first one and I think second most important mistake that Custer made was not taking the 2nd Cavalry when it was offered to him. This would have given him around a 1,100 men and that would have definitely been enough to defeat the Sioux. This can be countered by that Custer had too much pride with the 7th Cavalry and that he didnt want to share it with anyone else. Custer also knew that he was going to face the largest amount of warriors ever so having more men wouldnt hurt him at all and of course increase his chances of winning the battle. The next mistake that Custer made was underestimating the enemy that he was about to face. He figured that there would be about 1,500 warriors at max where there were actually almost double that. Custer probably didnt think that there would be any Cheyenne either. It was also known that at around that time of year the entire Sioux nation comes together for a big get together. This all stems back to others in the army not doing good reconnaissance of the area where they believed the Sioux were. The area that the army believed to be around at first stretched for 125 miles and was about 50 miles...

Paraphrasing Essay Example | Topics and Well Written Essays - 1000 words - 6

Paraphrasing - Essay Example This discovery is according to Ryan and Deci’s (2000), the assimilation of the organization’s demands with personal values and needs. Gaertner and Gaertner’s finding suggests that extrinsic rewards in combination to staff training or feedback to employees on their work have a greater impact on performance other than extrinsic rewards alone. The findings of Gaertner and Gaertner (1985), Dowling and Richardson (1997), Redman et al. (2000) and O’Donnell and Shields (2002) are supported by Frey’s (1997) contention that, once the wages and salaries go past a subsistence level, intrinsic factors are better motivators than extrinsic rewards. It also shows that using extrinsic rewards alone is difficult and motivation of staff will require intrinsic rewards such as recognition and satisfaction of a job well done and a sense of amazing work. Williams (1998) describes how different people have different values, drives and perceptions to things and that not all people are passive recipients who automatically conforms to working systems as the management would want. Etzioni (1988) and Larson (1977), values are a necessity and are crucial to an employee’s development and commitment to a particular organization in achieving required goals and objectives. Berry, Broadbent and Otley (1995) describe the control of an organization which includes elements such as, goal setting, performance measurement and rewards. Organizational control is generalized and employees in the caring services may consider remunerative motivation less effective in comparison to the normative reward of doing a job that can satisfy them As reported above in the results a null hypothesis is rejected. The Employees of this organization occur to be motivated by intrinsic rewards. The results debate with the conclusions of Gupta and Mitra (1998) that extrinsic

Research paper on a problem pertinent to my academic major

On a problem pertinent to my academic major (chemistry). Discuss and the problem and danger of being exp - Research Paper Example These accidents notwithstanding, Chemistry remains a fulfilling career and is, indeed, one of the best in today’s labor market as well as in the future. Introduction Though Chemistry is a mature and risk-laden discipline, it is an exciting, interesting and intellectually stimulating as well as financially rewarding career. Chemistry as a science deals with the investigation of the properties, composition and structure of matter, the transformation matter undergoes, and the energy changes associated with the transformation (Encyclop?dia Britannica, 2011). Chemistry has played and is playing a crucial role in conquering diseases, solving energy problems, addressing environmental problems, providing the discoveries that lead to new industries, and developing new materials and technologies for defense and global security. These represent some of the major issues that confront our society today and chemistry occupies a central position in resolving these issues. Thus the chemist re mains a relevant member of today society and will occupy that position as long as life exists on our planet. Apart from the reputation of being a chemist, is the fact that with a median annual salary of $90,000, the chemistry profession remains one of the best in the labor market (Peter, 2010). Furthermore, the interdisciplinary nature of today’s chemistry, offers the chemist the opportunity to connect with other members of the scientific community such as biologist, physicists, environmental scientist, geologist, geneticists, and even government policy makers. Thus the chemist is not an isolated individual rather a well-connected personality collaborating with others to make life on our planet exciting and interesting. The nature of current research in chemistry is another plus to the profession; indeed, today’s chemistry is interesting as well as intellectually stimulating. As chemist work in collaboration with biologist and physicist and other scientist to unveil na ture’ secrets, surprising yet interesting facts are gathered. Each answer creates more problems that need to be solved. This makes Chemistry the ideal science for anyone with creativity, intelligence, and persistence. As promising and fulfilling as Chemistry is as a profession, the profession has its other side. Chemistry has killed a lot of chemists even the most careful ones. Working in a chemistry laboratory is laden with risks. Exposure to chemicals has immediate as well as chronic effects. Injuries have been reported from implosion as well as explosion in the chemistry laboratory. Chemists have caught fire in the laboratory while some have died gradually without knowing due to exposure to ionizing radiation and toxic chemicals. It is worth mentioning that most of these accidents in laboratory are preventable if precautionary measures are followed. Given these risks associated with Chemistry, one cannot help but ask if Chemistry is worth practicing. This article seeks to answer that question. Discussion The benefits of being of chemist Key among the factors that influence career choices is economic & personal satisfaction, personal esteem, and society recognition (Bolles, 2008). With a median salary of $90,000, which is higher than the national $29,000 median salary, chemistry is a paying profession (Peter, 2010). According to the
