Solarize campaigns are helping communities across New England transition to renewable energy, but whatever happened to “efficiency first?” The same collective approach can work for deploying other sustainable energy solutions at scale and addressing the barriers to participation in both rural and urban areas. In Maine, this has been demonstrated by the award-winning “Weatherization Week” model which has helped weatherize over 350 island homes, 18% of the year-round homes in Maine’s 15 island communities, and is now being replicated by other organizations and communities throughout Maine to increase uptake of air sealing and insulation jobs, LED retrofits, and heating system upgrades. This interactive session will feature examples of effective partnerships between contractors, program administrators, and local leaders that are driving investment in residential efficiency services. Participants will explore opportunities for collaboration in their own markets, learning how to partner effectively to boost sales, program participation, and energy savings.
