Total energy consumption, performance year:
958,868.80 MMBtu

Clean and renewable electricity (report kilowatt-hours):
kWh MMBtu
Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) 82,334,352 Kilowatt-hours 280,924.81 MMBtu
Electricity from on-site, clean and renewable sources (rights retained/retired) 0 Kilowatt-hours 0 MMBtu

A brief description of the certified/verified sources of clean and renewable electricity:

OSU's electricity provider, OG&E, had the Cowboy Wind Farm built for OSU in 2012. As of January 1, 2013, OSU began purchasing 110 million kilowatt-hours (kWh) of wind energy, which represented about 67 percent of the university's total annual electricity use. Since then, actual wind energy usage has averaged at about 70 percent. During calendar year 2017, actual usage reached nearly 72 percent. This is a 20-year contract scheduled for renewal in 2033.
