This is something all schools should probably adapt, right? A high school in Arkansas, Bateville High School, switched over to solar energy back in 2017. Now, because of all the money they save through solar, the school is able to give their teachers 2-3 thousand dollar raises yearly. I have not spent time looking through the Chicago Public Schools budget but I think this is something they might want to look into. Solar energy helped put up some crazy numbers for the school too. According to their superintendent, Michael Hester, "The annual energy consumption of the school district decreased by 1.6 million kilowatts and in 3 years generated enough savings to transform the $250,000 district budget deficit into a $1.8 million surplus."
