There's a new sound out on the green grid of cotton fields that make up what West Texans affectionately call the "Big Country." Joining the hum of a seemingly ever-present wind is the rhythmic whoosh of spinning carbon-fiber blades on dozens of huge wind turbines.
It's a growing Big Country symphony. Roscoe, a farm town with a population of just 1,300, is about to become Wind City U.S.A. — the locus of one of the biggest wind farms in the nation and the world. It's a striking development in a state better known as the U.S. leader in emissions of global warming gases.
The wind project is largely due to the vision of a one-armed, 65-year-old cotton farmer named Cliff Etheredge. (audio and narrated slideshow)
