Appalachia has suffered the most with the loss of coal jobs, a recently released report says.

According to a report released Wednesday by the U.S. Energy Information Administration, coal production employment in the U.S. has been cut nearly in half since 2011.

According to the administration’s Annual Coal Report, coal production employment has decreased 42 percent since 2011, down from 92,000 employees in that year to 54,000 employees in 2018. The region suffering the most dramatic decrease is the Appalachian region.

According to the report, more than half of Appalachia’s coal mines have closed since 2008 and production has decreased from 390 million tons of coal to 200 million tons in 2018. The report shows that smaller coal operations have had the most difficult time competing in the current market and have typically been among the first mines to close.

The report cites increased competition from natural gas and renewable technologies for the decreases in coal production. The report says coal production peaked in 2008 with 1.2 billion tons of coal produced.
