Definition Of Energy Crisis Importance Of Energy Environmental Sciences Essay

Definition Of Energy Crisis Importance Of Energy Environmental Sciences Essay An energy crisis is any great blockage in supply of energy resources to an economy. It often refers to a decrease in the supply of electricity as compared to its demand. None can deny the importance of energy in todays world. Energy drives mans domestic life, industry, agriculture, and his automobiles, etc. Whenever there is a storage of energy all walks of life are affected. Pakistan face a severe energy crisis these days. Present energy crisis has passed all the previous ones. Pakistan has installed capacity of about 19500MW. The major contributors of this figure are WAPDA, KESC, IPPs and PAEC. WAPDA generates 11327MW and minority shares in the total population of energy in the country. KESC contributes 1756MW, PAEC 427MW and IPPs 5500MW. The country takes this amount of energy from three main sources: HYDREL, THERMAL, and NUCLEAR. HYDREL power is 6444MW, from which Tarbela power plant, Mangla power plant and Ghazi Barotha power plant. The main contribution towards the country tota l power is from thermal source. This type of energy is produced by Rental power plant(RPPS) and Independent power plant(IPPs) under authority of private power board. Pakistan atomic energy commission (PAEC) is generating electricity from nuclear fuel sources. Karachi nuclear plant and chashma nuclear power plant are producing 472MW of electricity. Pakistan has capacity to generate 50,000MW energy from hydrel source only but it produced only 6444MW out of this figure. The country has total coal reserve is 185 billion tones which can serve the country energy situation for centuries. The coastal belt of Sindh separate 1046 Km has wind energy potential of 50,000 MW according to some estimates. Pakistan has sunlight duration of about sixteen hours a day and twelve months a year and this sunlight can generate about 100,000 MW of electricity for Pakistan, almost free of cost. The current power production of country from all sources is about 13000 MW, Whereas demand is about 17500 MW. Thus this significant equality between the demand and supply of power and this disparity has pushed the country in crisis. It has been estimated that total energy requirements of the country in 2030 will be around 160,000 MW, Whereas present generation capacity of the system is only 19,000MW. Fortunately Pakistan is capable of this meeting target with the potential at its disposal. For example, its hydrel potential is close to 40,000MW, Gas can produced 50,000MW, coal can produced more then 50,000MW, and the balance of 1000MW can be produced by nuclear power plants. Only the need of time is better policy making. Energy crisis has its far reaching ravages from economic to social life. The factors which had led to this situation would be discussed in the pervious paragraphs. Industrial growth accordingly the demand of electricity has been multiplied in the past few year but, the government and concerned authorities have failed to keep pace with the growing demands of industrial sector and agriculture sector. Agriculture sector has grown over the years with its own strain over the power distribution equation but not anticipated by the policy. Agriculture consumption of electricity was about 11% in 2005-2006 which rose upto 14%, according to FBS. The rate of increase in demand is many times greater than the rate of generation of power. So, the result is energy shortage. Another factor responsible for energy crisis is corrupt practices of the masses in collaboration with the concerned authorities. Electricity theft is contained particularly in far flung areas. The employees of wapda and kesc are involved in this power theft by providing illegal connections to the people. People also enjoy more than one meter in the same home to evade tariff, It has divided the collection of revenue and also causes loss of power. Line losses of electricity during its distribution from the site of production to the ultimate consumer are high in Pakistan owing to its factors. The distribution lines are in Pakistan either outdated and damaged, there is no proper maintenance of these lines. Line losses from 20% of the total power transmitted through the lines. It means 20 units of every 100 units is wasted and not paid by the consumer. The roots of the energy crisis can be found to almost two decades back with advert of highly generous 1994 policy for independent power producer (IPPs). With this policy a dramatic shift occurred in the generation source and it made the country hostage of an irregular rising and falling in number or amount in international oil and gas prices. The present cause of energy crisis is over reliance on expensive imported fuel mix. Before the implementation of 1994 policy the country electricity generation was trusted on fuel mix approximately 70 or 30 in support of hydro thermal. This changed dramatically over the next decade and fuel mix become 30percent hydro an 70percent thermal by the end of 2010. The cost of this policy could be understood with the following comparison. Wapda is generating electricity from hydro source at Rs.1.03 kwh, While in public sector thermal power plant provided the same at Rs.8.5 kwh. However the (IPPs), provided the same at Rs.9.58 kwh. This cost increased fo r the consumer due to line losses and theft in the transmission and distribution systems. Not only single megawatt of electricity has been added to Pakistan national grid stations since 2000 record breaking economic growth and population expansion. In this land, blessed with fast flowing rivers, there is no reason for us to not increase our hydel capacity to lower electricity cost, Inter central trust shortage, regarding the location of dams is a major cause of this low hydel production. More importantly, those down rivers dont want to see their share of sources of water reduced. The project of kala bagh dam was conceived(responsible) almost half century ago. Had it been constructed on time Pakistan would not faced the energy problem that it is challenged today. Similarly gavader maga project has been built by china and balochistan is its biggest beneficiary but its own provincial leadership is raising all kinds of serious objections to make it controversial. World over coal based power is cheap and largest source of power generation. The abundance of this cheap power in the power mix of a country pulls down the average price of power and more electricity cheap and affordable. Coal based power is not rocket science. It is intermediated technology and takes an average of 36 months for a coal power plant project to come on stream. The demand for power is ever increasing but no maga project has been started since the start of energy crisis. According to some estimates the demand of power is increasing at a rate of 9% while the production rate has increased by 7% only. It has contributed to energy crisis. Not only the new generation capacity was added to the system but also the transmission and distribution network was upgrade. Pakistan has witnessed a population explosion over the years. It had population of about 84,254,000 in 1981 with 28.8% people living in cities. Current population of the country is estimated to be 17,800,0000 with 32.2% people living in urban areas. But the generation of power and population increase have remained out of this phase with one another leading energy shortage.

Ghosts in The Women Warrior Essay -- Literary Analysis

Envision yourself as encircled by strange, yet terrifying and evil spirits that trouble you in your worst nightmares. The spirits could desire something from you. In fact, they could aid you in locale of frightening you. Should you attend to them? What do you contemplate they are trying to notify you? In one of the inquiries above, notice the ironical use of the word â€Å"fact† that endeavors to obscure the fictitious nature of ghosts. It displays that the meaning of the word â€Å"ghost† is equivocal. In supplementary words, the word â€Å"ghost† is multivalued, that way that ghosts can purpose in extra than one way. The word â€Å"ghost† originates from the Aged English word â€Å"gast,† and its synonyms are â€Å"soul, spirit [good or bad spirit], existence, breath,† and â€Å"demon† (etymonline.com). In the book, The Woman Warrior, that is, ironically, subtitled as Memoirs of a Girlhood Amid Ghosts, the author, Maxine Hong Kingston, uses the word â€Å"ghost† as a metaphor to typify her confusion concerning discovering a difference amid reality and unreality – the difference that divides her American present that prefers and her Chinese past that her mother, Valiant Orchid, filters into her mind across talk-stories that steadily daunt her to cross her established bounds. Ghosts, in the book, change reliant on point of view. Anybody whose deeds deviates from what is satisfactory in one area is a ghost according to the associates of that society. To Chinese people, like Valiant Orchid, Americans are ghosts. On the supplementary hand, Chinese are ghos ts according to Chinese-Americans (including Kingston, who finds her past loaded alongside frightening Chinese ghosts). For Kingston, Ghosts, however, are not always scary; in fact, a little of them enthuse... ...Memoirs of a Girlhood Among Ghosts. Random House, Inc, 1976. Print Bucci, Diane Todd.

Engineering Ethics Essay

The responsibility of an engineer is to counter to a need through creating or building something according to the stipulated set of guidelines which performs a particular a given purpose. the creation ,plan or device should perform its stipulated functions without fail. However everything must eventually fail in some way to do its given functions in terms f the level of performance. Therefore engineers must always struggle to design their works in such a way that they avoid failure and more so a catastrophic failure which can lead to loss of property, loss of life or possible injury and damage towards the environmental user of that technology through the study and analysis of engineering disasters modern designers in engineering can how to create with little or no chances of failure and what no to do or what is referred to as engineering ethics. This essay is going to focus on the application of engineering ethics and the differences between a good engineer and a poor engineer. It is not a good argument to say that engineers should emulate the public in taking risks because the engineering failure is considered to be an engineering disaster through the public perception of risks. For example almost the same number of people die from airplanes, bicycles and trains but the public perception of the risks associated with air travel is always relatively higher than that of for bicycles and also trains. This is facilitated by the fact that there is much news reporting on airplane accidents and mishaps compared to the rail and road accidents also think it is not a good argument because most of the engineering disasters are considered to be human factors which include ethical failure. Design flaw is also another cause because they mainly result from unethical practices. I don’t think the argument is good because the deficiency in engineering ethics is perceived to be one of the derivation causes of engineering failure. This is because n engineer as a professional bears a responsibility to both the client, the employer, to the general public and to their profession. This means that they should perform their responsibilities in a very conscientious manner. This will not include only acting in the bound of the law but as a n ethical engineer he will try to always avoid conflicts of interest. To avoid this conflicts of interest the ethical engineer will avoid misrepresenting his knowledge by not accepting those jobs which are outside his area of expertise, by acting in the best ever interest of the environment and society, by fulfilling the terms of his contract or agreements explicitly and also by promoting the education of the young engineers in the his field. Many failures reported in engineering ethics usually have many legal consequences (Matscieng. sunysb. edu, 2003). There is a relationship between risk and safety in terms of management and assessment. For example risk management is perceived to be a process that is used to evaluate the probability of harm occurring and also the severity of that harm the results of this risk assessment can then be used to determine how work can be performed safely. If the risk is not acceptable decisions must be made on how supplementary protective measures that will assist in keeping the porkers safe. Safety audit on the other hand is a process that is used to determine whether or not the risk reduction strategy is reliable with the results of the results made during the risk reduction portion of the risk assessment process. Each risk reduction measure should be validated to ensure that is being in accordance with the decisions which are made during the risk assessment. Risk management includes the systematic use of the results of risk decisions when making decisions regarding the best practicable strategy that will be used inn protecting the workers form harm. On the other hand safety management is the system used in ensuring that the risk levels acquired during the risk management are maintained (Industrialsafetyintegration. com, 2008). When accidents occur investigations should be thoroughly done to ensure that the cause is detected. If the cause of the accidents found to have emanated from the designing or creation of the thing then the engineer who designed the thing will be responsible for the accident. One of the dues of diligence to be undertaken in this case include physical assessment test (PCA). PCAs assess the possible costs which will be acquired during the life of a loan. Major electrical, structural, site improvements, HVAC components, and plumbing of each structure are cautiously and totally examined for condition, completion status, general code conformance, sufficiency for their intended use, life cycle costs and extent of depreciation and defection. The other due diligence to be applied is the Probable Maximum Loss (PML). It evaluates the financial loss of a construction on firm soil owing to the vibratory shift from the maximum probable earthquake. PML can be customized to integrate effects of the site state and the value or quality of the building construction. The maximum feasible earthquake used to analyze this loss is defined as the event that has a 10% chance of exceedance in a 50-year disclosure or exposure period, commonly identified as the â€Å"475-year event. † The PML is calculated as a damage proportion that equals the estimated repair charge divided by the substitution cost of the building. The final standard of due diligence to be applied is The Physical Needs Assessment Report (PNA) refers to the actual structural and mechanical requirements necessary for proper building maintenance. The PNA can be a crucial tool in influencing the subject site value and estimated cost in possible repairs or investment in the property. PNA reports can be customized according to a client’s specific inquiry. Upon conclusion of the physical evaluation of the property, AEI provides a synopsis report outlining the costs to correct the deficiencies which have been noted. AEI also devises and presents commendations together with a budget to increase the physical and artistic condition of the property to make best use of its position in the market place. There are various qualities of a good and a bad engineer. For example a good engineer possess a strong analytical attitude for he possesses excellent analytical skill and continuously examines thing he continually thinks of the ways of making work better through his inquisitive attitude. This is unlike poor engineers for they always continue on dwelling on the early knowledge and are lazy because they do not always take time to analyze things. They always lack perception and that is why many up them give out shoddy performances. A good engineer pay attention to all details for he or she knows the consequences of omitting any details. A bad engineer is most likely to be less attentive to all the details and that is why some of the work may have some errors. A good engineer has excellent communication skills for they can translate complex technical lingo into English and also communicates well verbally with clients. A bad engineer has no fluent communication skills and he might also cause miscommunication with his client. a good engineer takes part in continuing education . this is because he always wishes to stay on top of the developments in the engineering industry.. changes in technology happens so rapidly and a good engineer will tend to keep abreast of the new ideas and research a bad engineer rarely notices the changes happening in his job industry and he is also lazy in taking part in the developments taking place is always innovative by developing new systems and also finding new ways of making the existing thing work more efficiently. A bad engineer rarely brings any new ideas at work and he may also lack the motivation when it comes to the actualization of new ideas. A competent engineer shows the ability of thinking logically because he always possesses top- notch logical skills. he has the ability to make sense out of complex systems and always understands how things work and also how problems come about. Incompetent engineers usually have hard time in foreseeing problems and do not apply his ideas logically to ensure that thing flow smoothly in the organization. a good engineer is mathematically inclined. This is because he possesses excellent skills in mathematics for we all know that engineering is an intricate science that usually involves complex calculations of varying difficult. Incompetent engineers are not very sharp mathematically and therefore they are brought down by complex calculations thus giving miscalculated estimates at work. A good engineer possesses very excellent problem solving skills. This is because he detects any causes of the arising issues and solves them immediately to ensure that all things go smoothly. A poor or incompetent engineer rarely solves the problems accordingly. There might be a discontent in his problem solution ideas which may make work operations inefficient. A good engineer is a team player. This is because he understands they are part of a larger together to ensure the success of the project. A bad engineer rarely cooperates in team work for he believes he is the only one excellently qualified or capable. A great engineer has excellent technical knowledge for they tend understand a variety of computer programs and other systems that are commonly used during an engneeriong project (Engineeringschools. com, 2006). There is a very strong relationship between a good engineer and a good person. A good person has a lot of integrity because he is trustworthy and honest. A good engineer also has a strong integrity for he ensures that he is trusted by the people he comes into contact with. A good person is compassionate for he cares about all people in general. A good engineer is also compassionate for he does his work excellently to ensure that no one is hurt through poorly designed structures. A good person happens to be very reasonable and courage because he stands up for what is fair and also points at the right direction always. A good engineer is also courageous for he doesn’t follow the perception of risks according to the public and acts on his ethical standards. A good engineer is also very reasonable because he plans for his actions so that he may not take a wrong step which might be accompanied by a lot of negative consequences. A moral competent person possesses the ability to promote and even desire to secure well being and to diminish human suffering. This is because he or she responds with the appropriate sensitivity and moral feelings when he comes across human suffering. A moral competence person also distinguishes moral and natural harm, right and wrong a moral competent person also shows the willingness to take initiative for appropriate action. He also has moral imagination for he has the ability to come up with alternative courses of action (Cua, 2010). A morally competent person also bears moral persuasion for he has the ability to persuade and also to be rationally persuaded by others. It is very hard for people to make evaluations of moral competence because we know that human beings are always characterized by pretence especially when they want to achieve something. Again moral competence in people is mainly driven by intrinsic and extrinsic motivations which may be personal that the public can not identify. Moral competence evaluations are necessary because if dealing with people who lack moral values can really be frustrating because a person who lacks moral competence rarely acts accordingly (Wilson, 2003).

John F Kennedy vs Lynden B Johnson essays

John F Kennedy vs Lynden B Johnson essays The question I am about to answer can not be answered in brief. To fully comprehend the similarities and differences between John F. Kennedys New Frontier and Lyndon B. Johnsons Great Society you must understand their intentions first. John F. Kennedy was not an ordinary President. He was one with a certain charisma, as some put it. He was very blunt and knew how to get what he wanted. During his rain as President, he created the reform program know as the New Frontier. The New Frontier was developed to assure Americans of the upcoming sixties challenges. This was a program that affected all. Under the influence of the New Frontier Kennedy promised to defend freedom around the world. He stated: Let every nation know, whether it wish us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend or oppose any foe in order to assure the survival and success of liberty. This we pledge and more. Soon Kennedys speech would be put to the test. The debate over communism or democracy was still going on. The Cold War had not yet ended. During his presidency Kennedy was determined to lower unemployment by creating more jobs. He expanded the space program and stimulated military spending. He also cut taxes to give Americans a little more money to spend. This tax cut lead to a period of prosperity. He proposed a medical care program for the elderly. It was rejected by congress. Kennedy appointed black officials to higher government positions to support a Civil Rights Law he was delaying to propose. Kennedys program was a big hit. A national poll indicated that at least 60% of Americans approved his presidential stature. However, Kennedy was soon going to learn that all of his good will and future plans would be evaporated. On November 22, 1963 John Fitzgerald Kennedy was assassinated....

The Use of the Modifier More in English

The Use of the Modifier More in English The modifier more is commonly used in English in a wide variety of situations. You are probably familiar with the use of more in the comparative form, but there are other uses as well. Below you will find explanations of each of the different ways more is used to modify nouns, as well as in the comparative form and as an adverb. More is different than (the) most which you can learn about on this page dedicated to the uses of most in English. Comparative Form The most common use of more is in the comparative form. More is used with adjectives of more than one syllable - with the exception of adjectives ending in y - to express that there is more of a particular quality. Notice that the opposite less is also used in a similar manner to indicate that there is less of a particular quality (This hike is less dangerous than the one we took last week.) Examples: My history class is more interesting than my math class.New York is more expensive than Seattle to visit. More Noun Determiner More is placed before a noun as a determiner to state that there is more of something. However, it is important to note that the preposition of is not used when speaking in general. Remember that the plural form is used when speaking in general about countable items or people (There are more students this year). When speaking about uncountable objects, use the singular form (We need more rice). Examples: Its important to eat more fruit in your diet during the summer.There are more books to read in the next room. More of Determiner Noun More of is used with articles and other determiners when speaking about a particular thing or group. This is true for people as well as for objects. Remember that the is used to indicate a specific object that both the listener and the speaker understand, whereas a is used to speak about something listeners do not which specific instance is referred to. Examples: He is more of a thinker than you might realize.Ill have to use more of this class to explain the present perfect. More Alone In some instances, its clear which noun more modifies. For example, in a restaurant, a waitperson might ask you if you would like more referring to coffee, water, etc. If the context is clear the noun may be dropped. Examples: Would you like more? - Sure, Id love more. (Mom talking to a child concerning cake)I wish I had more, but the economy is tough these days. (Friend talking about money) Number More Noun Infinitive A number used with more followed by a noun and an infinitive expresses that how many/much more there are/is to do of a certain task. One more ... to do can be substituted with another ... to do. Examples: There are three more tests to correct today.Jennifer needs two more credits to graduate. More as Adverb More can also be used as an adverb to indicate an increase in an action or feeling. The opposite of this form is less (i.e. I like him more every day. OR I like him less every day.) Examples: I like him more each time I see him.She wants more every time I talk to her. More and More The comparative phrase more and more before an adjective is used to state that something or someone is increasingly becoming a certain way. In other words, when stating that there is a growing tendency towards something use the phrase more and more before an adjective. The opposite of this phrase is less and less to indicate that something is decreasing (i.e. Its getting less and less expensive to buy a computer.) Examples: Its becoming more and more difficult to find a job.Peter is getting more and more nervous about his final exam.

Freedom of Speech Essay Example | Topics and Well Written Essays - 750 words - 2

Freedom of Speech - Essay Example You may ask what war am I talking about and I will answer with gratitude that this war is the war for the rights, freedoms and liberty to speak and act as an individual. Very significant for our little research is the existence of the person named Edward Snowden. A lot of people heard about him and about things that he has done. Nevertheless I will briefly remind about this massive international espionage scandal. Snowden worked for the government (CIA and National Security Agency) and stole secret documents of strategic value. He then has been convicted by absence on the matter of stealing government property and espionage after which he escaped from country and now is hiding in Russia. The most interesting in this are the files that he stole. Secret documents that became public property after The Guardian and The Washington Post received them from Mr. Snowden consisted mainly from the cases of violation of the human rights on the matters of freedom of speech and private space. These documents included facts about surveillance and using wiretaps in order to spy on the people and not only in the USA but all across the world. This once again made peo ple rethink what illusory â€Å"free† and â€Å"democratic† world they live. Such pieces are only known facts and there are most probably a lot more than that. Where is the line between national security and security of an average citizen and his private life? Do we live in utopia or dystopia and therefore should look out for the cameras like the main heroes in George Orwell’s 1984? I will only add on this point that most recently (May 7th) court of the USA stated that mass surveillance on the people was illegal. That became possible only thanks to the â€Å"crime† of Mr. Snowden and the documents he provided. DOS attacks nowadays are the best way to confront government. Internet and computers are the only sphere where government can be exposed and unmasked. People nowadays live in a

TV shows Essay Example | Topics and Well Written Essays - 500 words

TV shows - Essay Example Though the movies have their aspects that set them apart from each other, making them two distinct tales, they share many similarities. They cover similar disasters, which involves a large object heading for Earth, how they decide to destroy the objects before they hit Earth, and men die for the sake of the people still living on Earth. In Deep Impact, a teenage stargazer, with the help of a professional astronomer, discovers that a seven-mile-wide comet is headed straight for Earth. In Armageddon, the National Aeronautics and Space Administration learns that an asteroid the size of Texas, which is what remains of a meteor shower, is on a direct path for the planet. Both of these objects are large enough to completely destroy all life on Earth. Events such as these are referred to in these movies, as well as in real life, as ELEs, or Extinction Level Events. If plans are not formed and implemented in a timely manner to prevent the comet and asteroid from striking Earth, humanity will cease to exist as we know it. Both movies take a similar approach to solving their dilemma. In Deep Impact, it is determined that the only way to destroy the comet is for astronauts and scientists to plant many nuclear bombs beneath its surface and have them detonated. Armageddon refers to a similar method and decides that scientists and a drill operator should drill a single nuclear device towards the asteroid’s core. The goals are to completely destroy the comet and split the asteroid into separate pieces, which will bring about less destruction and even offer the possibility that the remaining pieces will completely miss the Earth or else burn up in the atmosphere. In both cases, the teams and their methods are only partially successful. Instead of being entirely destroyed, the comet is split into two pieces, with each piece still heading for Earth and just as dangerous when they were a whole. In Armageddon, the asteroid does break into two
