Coal production in Appalachia emits 1 million tons a year of potent greenhouse gas. It isn't CO2.

2. Coal Burning from Electric Power Plants

has decreased significantly over the last 2 decades. Natural gas now produces more and cheaper electricity than coal. There's literally thousands of megawatts of off-shore wind production planned off the New England and Mid-Atlantic regions. If these off-shore wind farms are built and can produce electricity on par with the price of their natural gas and land-based renewables counterparts then in all likelihood the last of the coal plants will be retired (too expensive to maintain and probably not needed as emergency stand-by units) in the next decade.

With the market for utility power coal nearly extinguished (think whale oil) the only real use for coal will come from the coking industry, which uses much less coal than just burning it to produce electricity. Unfortunately, emissions will continue to "leak out" from these abandon mines, but maybe at a lower rate. The area on the map is probably in a high volatile bituminous coal area. Mines in this area should be well vented to prevent gas build up and will cease once the mines shut down.
