Coal is primarily used as fuel to generate electric power in the United States. In coal-fired 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 high-pressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...

In 1846, Canadian geologist Abraham Pineo Gesner refined a liquid from coal, oil shale and bitumen that was cheaper and burned more cleanly than other oils. He dubbed this liquid 'kerosene' and founded the Kerosene Gaslight Company in 1850, using the oil to light the streets of Halifax and later the US. The first modern wells

Coal deposits occur in the Pacific Northwest, so there is a potential for coal fires to occur. Although Washington and Oregon coals have a history of spontaneous combustion, the scarcity of coal fires appears to be due to the temperate rainforest climate in these states. The Green River underground coal fire is the only known burning-coal fire.

In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements. When this material decays under water, in the absence of oxygen, the carbon content increases. The initial product of this decomposition process is known as peat.
