Willy Street Co-op on the East side of Madison is offering the community the opportunity to buy solar bonds through Legacy Solar Co-op to support Willy Street Co-op’s energy efficiency and solar electricity project with a return on their investment. The store will add 20 kilowatts of rooftop solar and 214 LED lamps to replace fluorescents that are on 15 hours a day. Bond holders earn between 3-5 percent interest on the bonds that they can cash in after 7 years, hold as a legacy for 25 years, or donate to the nonprofit host site or other nonprofit. Annual projected savings from Willy Street’s project are 40,000 kilowatt hours and 33 metric tons of avoided carbon dioxide emissions. To learn more
