By the way, on a national basis, coal has dropped from greater than 51% of electricity production ten years ago to less than 32% and is still dropping rapidly. Many coal plants have been retrofitted to burn gas, but there have also been several months where all new capacity has been renewable.
Don't believe the "war on coal" rhetoric. I'm a geologist and have worked in the coal industry over thirty years. It's pure market forces sinking coal. It would be going down just as quickly if the EPA didn't exist. It's mostly an economy of scale issue. Coal plants, by their nature, have to be huge and require investment in the billions. Gas (and now wind, as well) can be brought on line incrementally, and new units can be added quickly to meet needs. Gas and wind can also be idled without incurring big shut down / start up costs.
As long as gas is readily available, coal will die. Gas doesn't even have to be cheaper on a BTU basis. External costs swamp the difference.
Anyone who uses "war on coal" is selling you something.
I have a client trying to sell a coal mine in PA and no takers. Its cheaper to buy a gas lease and hook the well to the pipelines that already exist. With the shale boom in NY, PA, WV and Ohio, individual industrial plants can generate their own power and sell the excess to the utility. You can buy a genset to generate electricity relatively cheap and scale it up as needed. Coal plants are huge, complex and require much more maintenance.
