Low-income households in Colorado are getting a new question during visits from energy assistance agencies: Have you considered solar panels? It’s an innovative approach to solving two challenges at once: reducing greenhouse gas emissions as the effects of climate change appear across the state, and lowering low-income families’ electricity bills. The results can make a big difference for residents like Joe Anderson, whose power bills have been cut by two-thirds since 13 solar panels were installed free-of-charge on his ranch-style house under one Colorado program. “I felt like I kind of got the luck of the draw,” he said. Colorado is emerging as a national model for how to expand renewable energy to low-income homes. The state has been pursuing low-income solar programs since 2015, and it’s on track to have 20 megawatts installed by the end of 2019 as those programs ramp up.
