Here's a serious question for you to ponder: Why would we use wind and solar if it doesn't actually reduce CO2 emissions? It's not just an academic question. David T. Stevenson, Director of the Center for Energy & Environmental Policy at the Delaware-based Caesar Rodney Institute, researched how much wind and solar power was generated in the PJM electric grid (which includes Pennsylvania) from 2019 to 2021, comparing the increase of wind and solar with the level of CO2 emissions. He found that wind and solar power generation increased by 30% from 2019 to 2021, but the increase had *no impact* on carbon dioxide emissions (CO2). Carbon didn't go down. Yet prices for electricity increased due to using wind and solar.
