Appalachia

Replacing underground mining with mountaintop removal mining cost a lot of jobs too but it benefited the coal industry so no fuss was made about it. If they would get over their "war on coal" mentality and encourage more renewable energy (rather than actively discouraging it as is being done now) then I think there would be more jobs out there. Teach folks in these areas to install and maintain solar panels and offer state incentives for development of solar. Then you get job growth and begin a transition to a better energy economy.
