The electricity used at Cowboys Stadium for Super Bowl XLV on Sunday was offset 100 percent with the purchase of wind energy credits. For every megawatt-hour of electricity used to power the event and its associated facilities, an equivalent amount of wind energy will be generated at a wind farm in Texas, said green energy retailer Just Energy. All the electricity that powered the jumbo screens, TV cameras, the Black-Eyed Peas halftime show, and stadium lights, heated the food and cooled the beer will be generated by the Sweetwater Wind Farm located in Nolan County, Texas, 228 miles west of Dallas. The wind power offset is the result of an agreement between between Just Energy, the National Football League and the North Texas Super Bowl XLV Host Committee. Just Energy will purchase renewable energy certificates on behalf of the Super Bowl to offset all direct and indirect carbon emissions associated with power generation at major Super Bowl XLV venues.
