Do you know how much money your school spends on energy? Could that money be better used in the classroom, library or computer lab if your school became more energy efficient? Some schools are quick to invest in renewable energy projects like solar without first reducing inefficiencies in how they consume energy. This can result in putting up more renewable energy generation capacity than they need (or can afford). The first place to start in making your school energy smart is with energy efficiency projects, like updated lighting, HVAC systems, and insulation. Involving students in tracking the amount of energy saved is a great way to incorporate STEM into the everyday culture of the campus.
