Nine governments are moving toward having their cities powered by 100 percent renewable energy. Longmont and Fort Collins have the best chances.
Municipal utilities could lead the 100-percent renewable charge.
Of the six communities — from Burlington, Vermont, to Kodiak, Alaska — to reach the 100-percent renewable electricity target, five of them, including Aspen, are municipal utilities. The sixth is a rural electric cooperative.
It isn’t surprising that municipal utilities have taken the lead, said Elizabeth Doris, manager of NREL’s state and local policy and technical assistance project. “Municipal utilities own the resources. They are used to making tactical decisions.”
