Pennsylvania Gov. Tom Wolf signed an executive order directing the Department of Environmental Protection to join the Regional Greenhouse Gas Initiative.

Democratic lawmakers in Pennsylvania appear more hungry than ever to transition the state’s electricity consumption to 100% renewable energy.

Talen Energy agreed to pay a $1 million fine after toxic waste from its Brunner Island plant seeped into groundwater and the nearby Susquehanna River.

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.

Landowners united against Transource Energy's Independence Energy Connection said they doubt an alternate plan would be more costly, as PJM says.

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.

The fate of Three Mile Island looks bleaker as Pennsylvania lawmakers wrapped up hearings that considered subsidizing the state’s nuclear fleet.
