Fossil fuel, hydrocarbon-containing material of biological origin that can be burned for energy. Fossil fuels, which include coal, petroleum, and natural gas, supply the majority of all energy consumed in industrially developed countries. Learn about the types of fossil fuels, their formation, and uses.
Burning coal releases toxins. Coal contains sulfur and other elements, including dangerous metals such as mercury, lead, and arsenic, that escape into the air when coal is burned. Burning coal also produces particulates that increase air pollution and health dangers. Burning coal emits large amounts of carbon dioxide into the atmosphere.
Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine. In 2012, about 39 percent of all electricity in the United States was generated by coal-fired power plants, according to the U.S. Energy Information Administration.
