Where our coal comes from

Where the United States gets its coal. In 2021, about 577 million short tons of coal were produced in 21 U.S. states. Surface mines were the source of 62% of total U.S. coal production and accounted for 65% of the total number of producing mines. About 0.6 million short tons, or less than 0.1% of total coal production, was refuse recovery coal.

The footprint of coal

Historical data on surface-mined coal. Prior to World War I, data is not available on the amount of coal produced via surface mining; however, the amount appears to have been negligible. Surface mining reached 1% of bituminous (including sub-bituminous and lignite) production in 1917, and it first exceeded 10% of production in 1941.

Monitoring environmental impacts of surface coal mining
