U.S. Renewable Energy Growth Accelerates

Renewable energy markets surged in the United States in the first half of this year despite uncertainty over federal tax credits and a sluggish national economy, according to mid-year figures.

Wind, solar, and geothermal energy are all on the rise. At least 17,000 megawatts (MW) of these three energy sources are now under construction. According to the Energy Information Administration, renewable energy will account for about one-third of new electricity generation added to the U.S. grid over the next three years.



Wind energy is leading the way with 19,500 MW of installed capacity at mid-year, including more than 1,000 MW added in the last six months. The American Wind Energy Association (AWEA) second-quarter report [PDF] predicts that total additions for the year will come to 7,500 MW, boosting U.S. wind capacity by 45 percent. In Texas alone, more than 4,200 MW of wind capacity has been installed this year or is currently under construction. Iowa is in second place with 1,770 MW.
