October 2014 - Yahoo announced its 15-year partnership with wind energy developer OwnEnergy. Under a Power Purchase Agreement (PPA), Yahoo will purchase about 50 percent of the wind power from the 48-MW Alexander wind farm in western Kansas to offset much of Yahoo's energy usage in the Great Plains region. The wind farm is expected to generate over 100,000 MWh annually. The PPA is part of Yahoo's effort to engage in community- centric partnerships to buy wind power directly from local wind farms.
