BANGOR — A coalition of business, environmental and labor groups is kicking off a ballot initiative campaign it says would control energy costs, create jobs and cut pollution.

The coalition announced today in Bangor that it’s created a group called Maine Citizens for Clean Energy to collect signatures to put a question on the November 2012 ballot.

The question would ask voters if they want to require that at least 20 percent of Maine’s electricity to come from new renewable energy sources by 2020, while also requiring electric utilities to invest in energy efficiency whenever it would reduce energy costs for ratepayers.

Coalition members include the Natural Resources Council of Maine, the Maine Renewable Energy Coalition, Reed & Reed construction company and the Maine State Building and Construction Trades Council.
