The Princeton Review named Northland College and 17 others to its "2011 Green Rating Honor Roll" - a list of colleges that received the highest possible score (99) in its Green Rating tallies this year. Northland has two wind towers, numerous solar panels, geothermal heat in the campus center and library, and furniture made from recycled materials. Students have even built a campus building that is entirely off the grid, using locally-produced materials.
