So essentially my school has an Energy Innovation Competition, and I want to retrofit the café in our school library to be more energy efficient. The café has 4 fridges 2 coffee machines and 1 ice machine, and I want to find a way to decrease its energy consumption through maybe adding some tech/infrastructure that could make it more efficient? Please help with ideas!! Much appreciated!!

P.S. (Preferably but not necessarily kind of larp)
