Coal production from mines with mountaintop removal permits has declined since 2008, more than the downward trend in total U.S. coal production. Total U.S. coal production decreased about 15% from 2008 to 2014. Surface production decreased about 21%, and mountaintop removal, one type of surface production, decreased 62% over this period. Lower demand for U.S. coal, primarily used to generate electric power, has contributed to lower U.S. coal production
