Let Your Gadgets Soak Up the Sun
The region's recent run of days with temperatures in the 90s is a potent reminder of just how powerful -- and underutilized -- the sun's energy is. In fact, according to the Department of Energy, the nation's electricity needs could be met if all the sunlight reaching just a 100-by-100-mile patch of the American Southwest could be harvested.
