Oberlin College may not have LEED Platinum dorms, but that doesn’t mean the school doesn’t care about being eco-conscious. Each year, the Ohio school hosts an energy competition, challenging each of the dorms to use the least amount of energy per person. Each of the dorms is equipped with a system of lights (called energy orbs) that lets students know how much energy they are using, with green meaning less than normal, yellow meaning normal, and red meaning higher usage than normal. The school also replaced and recycled 10,000 incandescent light bulbs in 2007, switching to the lower energy and longer-lasting fluorescent bulbs. Dorm dining halls are also super green, using local, sustainable and organic ingredients, many grown right on campus. Other eco-friendly dorm options include car sharing, green move-outs and move-ins, bike rentals, and wastewater recycling.
