The amount of wind power that theoretically could be generated in the United States tripled in the newest assessment of the nation’s wind resources. Current wind technology deployed in nonenvironmentally protected areas could generate 37,000,000 gigawatt-hours of electricity per year, according to the new analysis conducted by the National Renewable Energy Laboratory and consulting firm AWS Truewind. The last comprehensive estimate came out in 1993, when Pacific Northwest National Laboratory pegged the wind energy potential of the United States at 10,777,000 gigawatt-hours. Both numbers are greater than the 3,000,000 gigawatt-hours of electricity currently consumed by Americans each year.
Wind turbines generated just 52,000 gigawatt-hours in 2008, the last year for which annual statistics are available. Wind speed generally increases with height, and most wind turbines are taller than they used to be, standing at about 250 feet (80 meters) instead of 165 feet (50 meters). 1.
