Go Green! Sports stadiums save energy

USA Today

You could view a National Football League stadium as a hulk of concrete and steel, where video boards and bright lights eat up electricity, refrigeration is needed to keep the beer cold, halftimes are flush-fests and cars idle before and after games.

On this celebration of Earth Day, hold the carbon-emitting negativity.

Since January, 11,000 solar panels and 14 wind turbines have been generating power at Lincoln Financial Field, home of the Philadelphia Eagles. The team’s 10-year-old “Go Green” campaign also includes reduced water and electrical use, recycled paper products for all tissues, conversion of cooking oil into biodiesel fuel, a digital version of the cheerleaders calendar to spare trees and compostable packaging for the hot dogs and Philly cheese steaks.
