Renewable energy supporters are voicing concerns over the bill recently introduced in the Ohio Senate that would repeal Ohio's renewable portfolio standard ("RPS"), which requires the state's utilities to procure 25 percent of their energy from renewable and advanced energy sources by 2025. Cleveland Mayor Frank Jackson said in a recent speech that the bill, sponsored by Sen. Kris Jordan (R-Powell), threatens Ohio's chances to rejuvenate its manufacturing base and become a leader in the clean-energy economy, according to an article in The (Cleveland) Plain Dealer. Another article in North American Windpower examines the potential fallout from the bill.
