Wind is the fastest growing renewable energy source today and has made up 35% of all new generating capacity added to the U.S. grid since 2007. That's twice what coal and nuclear combined have added in the last five years, according to the American Wind Energy Association (AWEA). And as U.S. developers take advantage of federal tax credits for renewables through the end of 2012, it's possible that 2012 may result in one of the largest number of wind projects completed in one year.

• United States currently has 49,800 MW of wind capacity installed , according to the American Wind Energy Association, and Energy Information Association reports show future estimates range from 66 to roughly 300 GW installed by 2030.
• The U.S. Department of Energy has conducted studies for areas with good wind regimes and concluded that wind resources have the potential to supply 20% of U.S. electricity consumption. 
• As of August 2012, there are more than 10,300 MW under construction across 30 states in this calendar year.
