The Ohio Attorney General's office says backers of a proposal to require the state to invest billions of dollars in solar, wind and other energy sources have met the requirements to get on the ballot. The Ohio Clean Energy Initiative amendment requires the state to invest 1.3 billion dollars a year over the next decade on energy infrastructure, research or development. The money would fund projects determined by the Delaware-based Ohio Energy Initiative Commission. The measure also calls for paying the commission 65 million dollars in annual operational expenses.
