BRUNSWICK (AP) – A nonprofit group that’s promoting sustainable economic development in Maine has come out with a plan it says could cut the state’s energy bills by at least $10 billion and create 10,000 jobs.

Portland-based Opportunity Maine told an Earth Day news conference in Brunswick that investments in a green economy also could create a $300 million a year marketing opportunity for Maine businesses.

The report calls for the state to meet at least 30 percent of its energy needs through efficiency by 2020. It also recommends that training and education be offered to potential candidates who could move into good jobs in the new energy sector.
