The 2021 MRES Sustainability Tour is part of the annual National Solar Tour, coordinated by the American Solar Energy Society (ASES) in all 50 states and organized in Minnesota by ASES chapter member Minnesota Renewable Energy Society (MRES). The Sustainability Tour gives prospective customers opportunities to visit energy efficient homes and buildings that are reducing their utility bills and their carbon emissions. In becoming a sponsor, you’re supporting solar installers, businesses, schools, homeowners and, most important, potential customers who care about their energy costs and environmental justice.
