250-megawatt nuclear facility produces an estimated 250‚000 tons of carbon dioxide during its lifetime. In contrast‚ coal-fired plants produce close to 2 billion tons of carbon dioxide every year in the U.S. alone while also emitting lots of other pollution: soot that causes lung diseases; sulphur dioxide and nitrogen oxides that cause smog and acid rain; and mercury that contaminates fish. In fact‚ coal kills 4000 times as many people as nuclear power‚ according to one analysis. 2) It is possible to generate

Also if we use less fossil fuels that means that all the digging and mining for coal‚ oil and gas can be stop and the environmet ‚the north and south pole will not be destroyed. Plus the turobines only take up a small amount of land unlike the coal powerd thermal power stations. Another reason is that the people can get jobs by making the turobines. There a lot of unemployed people in Britian and they could get

rock layers to intersect the coal seem that contains coal bed methane‚ CBM. Next‚ fractures are created or existing fractures are enlarged in the coal seem so that the CBM can be drawn from the well and pumped to the surface. These fractures are created or enlarged by using a thick water-based fluid which is gradually increased by rate and pressure. Then‚ over time the coal seam is unable to keep up with the fracturing fluid which results in high pressure causing the coal to fracture along the weaknesses

been retreating to a record extent. Coal-fired power plants are a major contributor of greenhouse gases and‚ as the U.S. Supreme Court has already affirmed‚ the EPA has the authority to regulate those emissions as pollutants. For the agency to have ignored what is so obviously the most pressing environmental issue of our times would have been the real outrage. But easily lost in the rule-making are two critical points. First‚ the EPA has not banned coal-fired power plants but has set stricter

Not only are nuclear plants dangerous but coal power plants have also caused several deaths in the past few years from accidents‚ and the byproducts of coal power plants have been linked to acid rain. To improve the safety concerns of nuclear power plants we can develope a more advanced technology and design to help with this concern. Turning the
