Solar, wind, geothermal and hydropower provided 100 percent of the energy for the game thanks to a partnership between the NFL and Salt River Project, the major energy provider in Phoenix. The company has a renewable energy portfolio with a capacity of 493 MW, a large majority of which comes from hydropower. The NFL is buying renewable energy certificates from SRP to offset its consumption.

The league is also partnering with the Arizona Department of Environmental Quality and a slew of other groups to support the replanting of some 84 acres of forest that was destroyed during the 2002 Rodeo-Chediski Fire.

Also, the company behind Amp Energy drink hosted a four-day stationary bike riding event to supply enough  power to cover a half hour of the Super Bowl’s pre-game show.

And you thought it was only the grass that was green at the Super Bowl.
