easily distributed all over the world; • Comparatively inexpensive due to large reserves and easy accessibility • Good availability • Inexpensive • Very large amounts of electricity can be generated in one place using coal, fairly cheaply. • A fossil-fuelled power station can be built almost anywhere, so long as you can get large quantities of fuel to it. Most coal fired power stations have dedicated rail links to supply the coal. Sounds good, huh! Think again! The important issue as of

What happens when soda is poured into a glass to quickly before it has time to settle? It spills over the edge and out of the glass, damaging anything in its path. This is what happens to the atmosphere when greenhouse gases are being pumped into it faster than it can be absorbed. Many people believe that global warming is a problem that can only be solved by big companies and the government. What happens when the government is handing out millions of dollars in tax breaks to big oil companies that

Heat-trapping greenhouse gases that contribute to global warming include carbon dioxide, methane and nitrous oxide. According to the U.S. Climate Action Report 2010, carbon dioxide emissions rose 21.8 percent from 1990 to 2007, largely due to increased generation of electricity and an uptick in transportation activities. In that same 17-year period, methane emissions declined by 5 percent and nitrous oxide emissions dropped 1 percent. Better technology and management of natural gas plants as well

Alternative Energy Sources Geology Many people believe that we must depend on fossil fuels for energy, where as the reality of it is the earth provides an abundance of renewable energy sources. These energy sources can produce enough energy that we would never have to use fossil fuels again. Alternative energy is the use of other energy sources instead of the use of fossil fuels or nuclear energy. Solar power can be used to operate cars and provide electricity to homes and businesses. Hydropower

Working Outline Thesis: The use of hydraulic fracturing or “Fracking” to provide natural gas is immoral because the risks far outweigh the advantages on an environmental and ethical scale. I. What is Fracking? A. Used to release oil or gas from underground formations of shale beds that are too hard to mine. 1. It can pollute local water systems * Toxins from the fracking leak into water systems and poison them * The toxins can get into the drinkable water supply and ruin them

Objective: To determine the importance of the different type of fuel cells, the advantages and disadvantages of consuming fuel cells and appropriate applications to each type of the fuel cells. Statement of the problem: Billions of people in advance, developing and poor countries are dependent in fuels for their living. Millions of people or even billions are travelling each day by boarding a bus, car, ship, rail transport, airplane or riding on a motorcycle powered by internal combustion

whole faced with a huge threat to its survival. Oil accounted for 95% of global energy used for transportation (Energy Bulletin, 2007), also other factors including energy security, concerns over carbon emissions from burning fossil fuels and increasing demands for fossil fuels (and cars) in emerging economies is pushing, and will continue to push, up the price of oil. As a result of these factors, the cost of petrol, used to power Toyota’s cars, was predicted to rise significantly, making Toyota’s

Climate change is attributable to both natural and anthropogenic factors. Anthropogenic climate change, which are also known as human induced climate change, is a result of increase in greenhouse gases, including carbon dioxide, methane, nitrous oxide and chlorofluorocarbons in the atmosphere, increase in atmospheric aerosols, and changes in land use, for instance, through cutting down of forests to create farms. The increase in greenhouse gases in the atmosphere causes an increase in the amount

Rise of Carbon Pacing global economy and industrialization pressurized world to increase its fossil fuel consumption from 4.9 TW in 1965 to 13.62 TW in 2006. The immense increased in HC based Fuels has resulted in large amount of Carbon Dioxide emission. This Green House gas (GHG) attributed to the environmental warming and resulted in an increase of 0.74 degree for past 100 years. Rising global temperatures will cause sea level to rise and alter local climate conditions, affecting forests, crop

文勇的新托福精选阅读（原黄金29篇）真题[2010年4月3日 5.8版本] 俺常常收到同学们的邮件，要我推荐各种各样阅读材料,问我iBT的复习资料中 Barron, Longman, Delta等等哪个更好。我其实很无奈---因为尽管这些机构很大牌,但大牌丝毫都不意味着文章“质量高”(比如你可以想想三鹿奶粉)---说这些机构的文章质量不高,并不是说文字写得不好,而是说这些文章的句子结构, 论述方式, 出题思路与ETS的并不一致(有时候甚至大相径庭)：用这样的材料训练，实在是 事倍功半。 于是，我们实在应该去找找由ETS出的iBT文章来做：（我们能够找到的|由ETS编纂的标准iBT文章有） 1. OG[1]之中的13篇文章[2]；（其中3篇为第三版OG之中的文章） 2. 13次（套）TPO[3]之中的3*13=39篇文章[4]； 3. 早期[5]报名之时ETS赠送的3篇在线测试题 4. ETS官方给出的模考软件之中抽出的1篇文章； 于是这个文档在我的一时兴起之下，出现了： OG拿在手上，可以一个个字的敲成电子版；TPO的所有考试都是在自己的计算机进行，于是可以一边花钱参加考试
