The War on Coal is coming from inside the house:

Berkeley Energy Group, a coal mining company in Kentucky, announced plans to build the largest solar farm in Appalachia on top of a reclaimed mountaintop coal mine. The solar plant is expected to produce 150MW of electricity.

The company says the project will provide construction jobs to an economically-depressed area. They also say they will use as many of their coal miners as possible to operate the new solar plant (presumably retraining them as necessary).

As I recall, there was a presidential candidate that proposed this very sort of project and retraining, but she was evil or something.
