Where It S Always A Windy Day
Like other alternative-energy brainstorms, the economics aren’t wildly compelling. De Le Ree figures that freeway wind could allow each turbine to generate about 9,600 kilowatt-hours a year, worth just under $800 at current prices—a low return on the estimated $48,000 cost of each overhead turbine. But higher traditional-energy costs and the desire to create electricity in an urban environment could make these projects viable someday. And who knows? Maybe they could get corporate sponsors to set up turbines at NASCAR tracks, where the 200mph race cars could really get the lights burning bright....
