ReVision Energy cofounders Phil Coupe and Fortunat Mueller share the philosophy that a successful business can be used to create positive social change. The renewable energy contracting company became a Certified B Corporation last year, after meeting rigorous standards of social and environmental performance, accountability, and transparency. “This was a powerful recognition of our very deliberate efforts to build a company that reflects our values,” Mueller says. “B Corporations compete to be not just the best in the world, but also the best for the world.” Last year, Revision Energy built the state’s first net-positive office building, which will generate more energy than it uses annually, and installed the solar array on Friends School of Portland in Cumberland, which is the first net-zero school in northern New England. As costs for solar technology have declined in recent years, Revision Energy has sought to make solar energy more accessible in Maine and New Hampshire, with power-purchase agreement projects for municipalities and organizations and community solar farms for groups of residential users. In 2015, the Natural Resources Council of Maine honored Coupe and Mueller with its Conservation Leadership Award. “I’m in the solar industry because I want to keep Maine economically and environmentally sustainable so my kids and their kids can enjoy this special place,” Coupe says.
