This spring, Oregon State University started using its largest grounded solar array under the universitys Solar by Degrees program.
The program has three arrays covering 10 acres in Corvallis installed by Portland-based SolarCity, providing the campus with 2,200 kilowatts of power and reducing its overall carbon footprint.
According to the Environmental Protection Agency's Greenhouse Gas Equivalencies Calculator OSUs clean energy is the equivalent of reducing carbon emissions from 312 homes or 477 vehicles.
OSU has two more arrays in Aurora and Hermiston, but the largest is on 35th Street in Corvallis. Since that array went online, the schools electricity bills are 50 percent of what they cost in 2013.
At two Corvallis solar array locations, OSUs College of Agricultural Science grazes sheep to optimize their land. They are planning a bee and insect pollinator habitat in the array in Aurora.
OSU hopes to reduce its grid usage by 80 to 85 percent each year.
