OWU is a big place. Of all the school I have been going to, OWU is the biggest one. I have paying attention to the lights in many building on campus, and there are many of them, in the library, in Hamwil, in Science Center, and especially in the dorms, at unnecessary time, are turned on. That is a totally waste of electricity for a big campus like this. There should be some solutions for this problem, either reminding students and staff to turn off the lights whenever they go out (if not, the supervisor can report them) or replacing those lights with motion sensors lights.
