AH, Dorm life: cramped space, bad food, and-what's this?-solar panels. Schools around the globe have taken to greening campus housing with innovations such as renewable energy, recycled building materials, and composting facilities. Last year 318 students at California's Pitzer College moved into a new residence hall that has rooftop gardens, solar panels, and low-flow showers and toilets. Most building materials, including lumber and metal, came from within 200 miles of the campus.
