The development of science and technology has led people to consider using alternative fuels to generate electricity. There are many alternative fuels that can produce electricity, such as natural gas, nuclear power, wind power, hydropower, etc. (fossil fuels used to generate electricity in North American power plant emissions). According to 2009 U.S. Energy Information Administration statistics, the use of coal remains the primary energy source for generating electricity. The sources of electricity in the United States were produced by 44.9% coal, 20.3% nuclear, 23.4% natural gas, 1% oil, 6.9% conventional hydroelectric power plant and 3, 6% others (Electric Power Monthly with data from February 2014). ). Coal is the primary source of electricity in many parts of the world, including the United States. One of the reasons why most countries prefer to use coal to generate electricity is that the cost of using coal is cheaper than other but powerful sources. Coal-fired power plants are much easier to install than other power plants. Producing electricity from coal has many advantages. Coal as a source of electricity is economical, safe, efficient, and it is easy to eliminate secondary pollution, etc. Consequently, the use of coal must remain a status and cannot be replaced by other fuels. The use of coal is one of the most historic ways of generating electricity in the world. According to the book Your World in Motion: The Story of Energy by George Barrow, the author stated that the first time people used coal-fired thermal power was at the Gare du Nord in Paris in 1875. Generator technology, steam turbine manufacturing and power transmissions were improved step... middle of paper......earthquake revised to 8.0.
