Lincoln Financial Field, the home of the Philadelphia Eagles, has taken dramatic steps to green the stadium, including measures to produce all of their energy on-site. The solar and wind array offsets 100% of all energy use on non-game days, producing and feeding energy back into the grid. Located at opposing ends of the field, the 14 UGE-4K turbines were strategically placed. They provide "a visual representation of our commitment to sustainable efforts," said Eagles president Don Smolenski. The system was also designed so that it won't interfere with the fan experience. A custom braking system for the 14 turbines will ensure immediate stoppage if ever necessary. The result is a project that will save millions in energy costs each year.
