Tribal colleges and universities around the country are harnessing natural sources of energy on their campuses. Renewable energy and sustainable building design have many advantages--they save money and provide healthier learning and working environments while allowing people to live in greater harmony with the earth. This article discusses several tribal colleges and universities that are at the forefront of the green campus movement. One of these, the new campus of Turtle Mountain Community College (TMCC, Belcourt, North Dakota), will become the first tribal college campus--and apparently the first campus anywhere--to become completely powered by renewable energy when it erects and turns on its wind turbine. The utility-scale turbine will produce 660 kilowatts, powering the campus and providing excess electricity that the college can sell to the local utility company. The new campus is a 145,000-square-foot, two-story building, which is designed around the concept of the Four Directions and the Seven Teachings of the Ojibwe. It also utilizes geothermal energy from 560 wells, 160 feet deep under the parking lot. The following colleges that exemplify the green campus movement are also discussed: (1) The Institute of American Indian Arts; (Santa Fe, New Mexico); (2) Salish Kootenai College (Pablo, Montano); (3) Sitting Bull College (Fort Yates, North Dakota); (4) Sisseton Wahpeton College (Sisseton, South Dakota); (5) Blackfeet Community College (Browning, Montana); (6) Southwestern Indian Polytechnic Institute (Albuquerque, New Mexico); and (7) Crownpoint Institute of Technology (Crownpoint, New Mexico).
