A group of environmentalists wants Michigan's utility companies to use 30 percent renewable energy by 2030. The wind and solar advocates have started a campaign to get their proposal on the 2018 statewide ballot.
John Freeman is leading the campaign. He says utility companies aren't taking advantage of the cheapest power sources available: solar and wind.
"Everybody will save money," he said. "Plus, we get the added benefit of having much cleaner air because solar and wind don't produce any pollution."
A similar campaign was defeated in 2012. Michigan's two largest energy companies, DTE Energy and Consumers Energy, spent more than $20 million fighting that initiative.
Under current state law, companies will be required to go to 15 percent renewable energy sources by 2022.
DTE Energy CEO Gerry Anderson opposes the new measure.
He told Michigan Radio, "Complex public policy should be undertaken by ballot initiative as a last resort."
Freeman says the campaign expects to begin collecting signatures today.
