LEWISTON, Minn. — Lewiston schools have leaped into the renewable energy era with newly installed solar arrays at the high school and the elementary school. The project has 658 solar panels strategically placed to maximize energy production. Together the panels generate 493,000 kilowatt-hours of electricity a year — enough to power 41 homes. Put another way: The panels will generate 39% of the energy used by the two school buildings. Said Bree Maki, School Board chair: “Those savings can go right back into the classrooms to benefit our kids.” The project as funded by $633,000 in federal and state grants.
