24 Hours of Reality: Greensburg Goes Green

After a massive tornado leveled the small town of Greensburg, Kansas, in 2007, Mayor Bob Dixon, decided to use the reconstruction as an opportunity for change. “The only true green and sustainable things in life are how we treat each other,” he says, “and that includes how we treat future generations.” Today, Greensburg's goal is to be 100%-powered by renewable energy sources -- and it's well on the way. This conservative farming community has built one of the greenest towns in America.
