U.S. federal data show installed wind turbines are taller and more efficient than in the past, though hydroelectric power still holds a slight edge. The U.S. Energy Information Administration found that the average height and power generating capacity for wind turbines installed in the country are taller and more efficient that in years past. “Since 2012, the average height of wind turbines installed in the United States has been about 280 feet, or 80 meters. Before 2006, few wind turbines were as tall as 280 feet,” the federal brief found. “Wind speed typically increases with altitude and increases over open areas without windbreaks such as trees or buildings.” GE Renewable Energy, one of the industry leaders […]
