COLUMBUS, Ohio (AP) — Battle lines are being drawn over whether Ohio should scrap its renewable energy standard, which requires power companies to generate a portion of their electricity from renewable sources such as solar and wind.

In hearings last week, Ohio Senate Public Utilities Chairman Bill Seitz, a Cincinnati Republican, reopened discussions on the 2008 state law, which said utilities must produce 12.5 percent of their electricity from renewables by 2025. The law also set energy efficiency targets to be met by the companies.
