On May 4, 2007, an EF5 tornado ripped through the city of Greensburg, Kan. It's estimated that the tornado was wider than the dimensions of the city itself. By the time the winds subsided, at least 95 percent of the city had been leveled.
Faced with the daunting task of having to rebuild from almost nothing, the residents of Greensburg opted to reconstruct their city better than before. In fact, today the city's name is more apt than ever — Greensburg is rebuilding as a "green" city. All buildings are being rebuilt to LEED platinum standards, and the city's power is being supplied by 10 1.25-megawatt wind turbines.
