GREEN BAY, Wis. (AP) -- The green and gold is going greener.

The Green Bay Packers plan to buy renewable energy to power Lambeau Field for home games this season, including the annual Family Night event during preseason training August 3 and any postseason play.

The renewable electricity costs about 15% more than standard power and is generated by wind turbines and bio-gas facilities in the region.

Team officials say the move is only part of continuing efforts to make the organization more environmentally friendly.

A new recycling program last year is credited with keeping 6.6 tons of plastic, glass and cardboard out of landfills.
