Wind generation potential in the United States

The wind generation potential in the United States far exceeds demand. There are only two states with no commercially significant wind power potential, Mississippi and Florida. Florida has the potential to install 900 MW at 25% capacity factor 100 meter high turbines,〔(Florida 80-Meter Wind Map and Wind Resource Potential )〕 and Mississippi the potential to install 30,000 MW at 25% capacity factor 100 meter high turbines.〔(Mississippi 80-Meter Wind Map and Wind Resource Potential )〕 For commercial operation, a capacity factor of at least 35% is preferred. There are no locations in either state that would achieve 30% capacity factor. In contrast, North Dakota, the windiest state, has the capacity to install 200,000 MW at 50% capacity factor 100 meter high turbines.〔(North Dakota 80-Meter Wind Map and Wind Resource Potential )〕 Texas, although not as windy, is larger, and has the capacity to install 250,000 MW at 50% capacity factor,〔(Texas 80-Meter Wind Map and Wind Resource Potential )〕 and 1,757,355.6 MW of at least 35% capacity factor, capable of generating 6,696,500 GWh/year, more than all of the electricity generated in the United States in 2010.
By the end of 2011, the United States had installed 46,919 MW of wind power, and generated 94,652 GWh of electricity from wind power in 2010.〔
The annual production of a wind turbine is a product of the capacity rating, the capacity factor, and the number of hours in a year. A 200 MW wind farm at 35% capacity factor will generate approximately 613.2 GWh/year.〔200x0.35x24x365/1000=613.2〕
In addition to the megawatt wind farms, community scale single wind turbines of from 250 kW to 750 kW are typically 50 meters high, and residential or farm wind turbines are typically 15 to 40 meters high. To address these markets, maps are available showing wind potential at 30 meters〔(Residential-Scale 30-Meter Wind Maps )〕 and 50 meters.〔(Community-Scale 50-Meter Wind Maps )〕
The United States generated 4,125,060 GWh of electricity in 2010.〔(US Energy Information Administration. "Electric Power Annual 2011" ) Released: January 2012, Revised March 2012〕
N/A = Not Available
NA = Not Applicable (no shoreline)
The United States has trailed other countries in the development of off-shore wind farms, and it is possible that the first off-shore wind farm in the United States will be installed in either New England or New Jersey in 2013.〔(The War to Build America’s First Offshore Wind Farm )〕〔(Firm set to move forward on offshore wind farm near Atlantic City )〕 Other locations that could be the first are Virginia, Maryland, and Texas.〔(U.S. Offshore Wind Farms: The Race is On? )〕
