Sign-ups close tomorrow for the EcoRep’s third annual “Do It in the Dark” Energy Challenge! The competition is designed to encourage energy conservation and gauge students’ environmental habits and beliefs. Sign-up now, fill out a brief survey, and potentially win prizes! The dorm that reduces its electricity use the most per capita compared to last year will win over $500 in prizes. By registering and filling out the “Sign-Up Survey,” you will be entered into three additional raffles that will take place throughout April. Keep filling out weekly surveys and refer your friends to increase your chances. So sign-up, tell a friend, and “do it in the dark!”
