Democratic Governor Steve Beshear of Kentucky has called on the Obama administration to axe a pending environmental regulation that would effectively ban the construction of new coal-fired power plants.

In a letter to the Environmental Protection Agency sent last week, Beshear asked the agency to consider an alternative approach to regulating greenhouse gas emissions that would allow power plants to still burn coal, arguing that the economy thrives on cheap, affordable energy.

Beshear is not the first Democratic governor to rebel against the Obama administration’s environmental agenda. Last week, the Democratic governors of Montana and West Virginia filed amicus briefs with the U.S. Supreme Court that challenged proposed federal limits on greenhouse gas emissions.
