"...even insiders acknowledge that the coal sector is not going to recover even with these rules rolled back, not least because of mechanization. Recent Department of Energy statistics show that the coal mining industry employed roughly 66,000 miners in 2015, compared to an estimated 3 million jobs supported by clean energy. Therefore, the likely impact of the order on the coal industry will be fairly weak in the near term and, at best, mediocre in the long term. While reversing the moratorium on new coal mining leases will open new sources of supply, it will not in itself reverse the trends in energy markets that have increasingly favored gas. In addition, other regulations to control air pollution will continue to restrict the burning of coal for electricity." - Brookings
