Only about one-third of those approvals were for permit applications filed after SB 52’s effective date.

It’s not just solar and wind — Ohio has also stymied energy-efficiency efforts over the years, which would have additionally cut down on pollution and saved money for residents. The Save Ohio Parks’ report doesn’t consider the effects of the state’s infamous House Bill 6, which eliminated utilities’ energy-efficiency requirements after 2020.

Those impacts would have been quite sizable, said Mike Specian, a utilities manager with the American Council for an Energy-Efficient Economy, who shared his separate analysis with Canary Media.

If utilities had continued to achieve energy savings for customers after 2020, the cumulative savings could have been as much as 70 terawatt-hours, or 70 million megawatt-hours, Specian said. That high number is partially because energy-efficiency investments provide benefits, on average, for nearly a decade. ​“Those savings deliver year over year over year,” he said.

The mix of thwarted solar and wind projects alone likely would have displaced 7.1 million metric tons of carbon dioxide emissions from fossil fuel plants, said Ben King, a director with research firm Rhodium Group’s energy and climate practice. Carbon dioxide is a major greenhouse gas that drives human-caused climate change.
