Pennsylvania Senate Minority Leader Jay Costa wants other lawmakers to sign onto his plan to cap energy sector emissions.

Three nuclear plants facing early retirements in Pennsylvania and Ohio would keep consumer costs lower if they stay online, PJM concluded.

An attempt to save Pennsylvania’s Three Mile Island fell apart, but that doesn’t mean state lawmakers will abandon support for nuclear subsidies altogether.

Pennsylvania joined the U.S. Climate Alliance after releasing its own action plan to achieve a 26% reduction in statewide greenhouse gas emissions by 2025.

Critics of a bill to subsidize Pennsylvania’s failing nuclear fleet advised state lawmakers to put the brakes on the proposal, saying it would distort the deregulated energy markets.
