In school energy is consumed by using light for Parents, Teachers, and Students to see when they enter school and when they walk from room to room. You need to see where you’re going at all times. Since a couple of years teachers have been using projectors to teach the class. They use it because it is an easier way to teach the class and the subject. They also use energy for the school athletic department. Whether it’s for basketball, football, baseball, and more sports. They use energy because most of the sports use a shot clock to keep track of the score.
