Coal is one of the main sources of energy in the United States, accounting for 14% of domestic primary energy production in 2019, according to the U.S. Energy Information Administration’s (EIA) Monthly Energy Review. Nearly all of the coal consumed in the United States is produced domestically. Most U.S. coal is consumed by the electric power sector to generate electricity, and some coal is exported. The U.S. coal flow diagram visualizes the flow of U.S. coal energy from supply (production and imports) to disposition (consumption, exports, stock withdrawals, and losses).
