Via EIA: ” U.S. coal production is projected to decline by about 26%, or 230 million tons, between 2015 and 2040 in EIA’s Annual Energy Outlook 2016 (AEO2016) Reference case, which assumes the implementation of the Clean Power Plan (CPP). In a scenario that assumes the CPP is never implemented (No CPP case), U.S. coal production remains close to 2015 levels through 2040. Although production in each major U.S. coal supply region is expected to decline when the CPP is implemented, the magnitude of the effects differs because of differences in coal quality, pricing, and the markets served by each region. In 2015, the coal production shares of the West, Interior, and Appalachian regions were 55%, 19%, and 26%, respectively. In the scenario without the Clean Power Plan, these shares were expected to shift to 52%, 29%, and 20% by 2040, respectively, as coal production from the Interior region increases while coal production in the West and Appalachian regions decreases. In the Reference case, the decline in coal demand impedes growth for the Interior region and leads to even larger declines in the West and Appalachian regions. By 2040, market shares for the West, Interior, and Appalachian regions are 51%, 26%, 22%, respectively…”
