Georgetown, Texas is a relatively small city of 50,000 people, and its city-run utility recently announced that it would rely entirely on wind and solar energy in just two years. Georgetown plans to achieve this feat by purchasing energy from local solar and wind ventures. Texas gets plenty of sun during the days, and it tends to get windy in the state at night, so getting energy from both sources should cover the energy needs of the town. In an additional benefit, the move also saves water in a state that is notoriously dry. As Slate notes coal-burning power plants not only rely on non-renewable fossil fuels, but also use up stunning amounts of water, a resource also craved by agriculture, and, well, people.
