Coal-fired Power Plants
Coal fired power plants play a huge role in the United State's production of electricity.
Coal is crushed into a very fine powder. The powder is burned and the heat is piped at high pressure over a turbine, causing it to rotate, producing electricity. Coal can not be reproduced after it is burned therefore it can not be considered a renewable energy source. Coal costs less than any of the other fossil fuels. Coal’s share of total world energy use climbed from 25 percent in 2003 to 26 percent in 2004 and is expected to increase to 28 percent by 2030. The world’s largest producers and consumers of coal are China, Poland, Russia, India and the United States.
In 2006 the U.S Department of Energy started an improvement project for the coal plants. in 2006 coal plants produced 36 percent of the United States Carbon dioxide emissions, so something needed to be done. Carbon Capture Technology is the newest development in making coal plants cleaner.
United State's Consumption
57% of electricity in the United States comes from Coal Fired Power Plants. The following table presents the amount of coal that is used for electricity in each state.
