“Living in New York and Washington, Greg Wortham heard all the grand talk about green energy from liberal politicians. Then he returned to the place where he grew up, a small town that embraced wind power so warmly that within a couple of years of the first turbine turning, it had some of the biggest farms on the planet.  Yet Wortham is not from California, Oregon or New England, but a deeply conservative sector of Texas on the edge of the Permian Basin, one of the most bountiful oil and gas patches in the world. The welcome sign that greets motorists as they arrive in Sweetwater along Interstate 20, a three-hour drive west of Dallas, is not in the shape of an oil derrick or pumpjack, though: it’s a wind turbine blade bearing the town’s motto, “Life is sweet in Texas”.”
