Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...

The generation of electricity begins at the power plant— where fuel sources such as coal, natural gas or hydro are used to transform water to steam by a heating process. For example, in most coal fired power plants, chunks of coal are crushed into fine powder and are fed into a combustion unit where it is burned.
