New York officials unveiled plans for the Freedom Tower — the centerpiece of new construction at the World Trade Center site — on December 19th, including plans to incorporate wind turbines that will generate 20 percent of the building's electrical power needs. If built as planned, the Freedom Tower's use of wind turbines would be the world's first large-scale integration of wind turbines into a building. Wind turbines are generally not suited for urban environments because of the turbulence created by nearby buildings, but the height of the Freedom Tower may overcome that difficulty.
