There's a heat pump revolution happening in Maine. Already over 100,000 of the 600,000 homes in Maine have heat pumps, and their plan is to be over 300,000 by 2027. One out of every 14 heat pumps in the U.S. is going to Maine, though it is only 0.42% of the US's population. We talk to Andy Meyer, Senior Program Manager at Efficiency Maine, to learn how they've done it, and how it's saving Maine residents a lot of money, even in a cold-weather climate.
