Clean energy advocates in Pennsylvania are weighing whether to throw their support behind a proposed bailout for the state’s nuclear power plants. The state’s environmental groups have said little publicly about the plan recently floated by two legislators, but behind the scenes some see the debate as a chance to make more progress on energy efficiency and renewables.Much like the Green New Deal, though, any bargain will have to contend with decades of cultural and political baggage with potential to splinter support.“Historically, nuclear power has been one of the big bugaboos of the environmental movement. That continues to the present,” said John Quigley, director of the Center for Environment, Energy, and Economy at Harrisburg University and a former state environmental secretary.
