American wind power topped 4% of the US power grid for the first time last year and has delivered 30% of all new generating capacity for the last five years. In Iowa and South Dakota, wind power now exceeds 25% of total electricity production. In nine states, it provided more than 12%, and in 17 states, more than 5%.

Wind power generated 4.13% of all the electricity in America in 2013 as the fifth-largest electricity source in the US, according to the latest data from the Department of Energy’s Energy Information Administration (EIA). That is enough to power the equivalent of 15.5 million American homes, which is equivalent of all the residential households in Arkansas, Colorado, Georgia, Kansas, Nebraska, Nevada, and Ohio combined.

“Wind energy continues to make inroads as a major contributor to the US power mix,” said Elizabeth Salerno, Vice President of Industry Data and Analysis for the American Wind Energy Association. “The electricity generated by American wind power has more than tripled since 2008 not only due to significant growth in new wind projects but also technology innovation leading to more productive wind turbines.” All renewable energy sources now deliver nearly 13% of the nation’s electricity.

Texas, the state with the largest electricity load and the most installed wind capacity, also generated the most electricity from wind energy – over 35.9 million megawatt-hours, or enough to power 3.3 million homes. ERCOT, the main electric grid in Texas, received 9.9% of its electrical generation from wind energy during 2013 and is on track to top 10% in the coming years considering the 7,000 MW of new capacity now under construction in Texas.

The top states for installed wind capacity all set records in 2013 for the amount of electricity generated. Texas, Iowa, California, and Oklahoma each generated enough electricity to power more than 1 million American homes.

The geographic diversity and abundance of American wind installations is a reflection of the United States’ strong wind resource. In a 2010 study, the National Renewable Energy Laboratory reported over 10 million MW of wind resource in the US, enough to power the equivalent of the nation’s total electricity needs 10 times over.

The wind energy industry started 2014 with a record 12,000 MW of wind project capacity under construction and will deliver even more clean and affordable energy to our nation’s electricity generation portfolio.

    Some political theorist optimistically characterized the US federal system allowing there to be 50 different labs for governmental policy.this map would seem to indicate that magically from all four directions wind disappears as soon as it crosses into those living in nebraska ever travel to the surrounding states?can anyone explain?

      Nebraska lost the key to their lab.

    • Peter Gray

      Nice observation! There’s an even steeper drop-off as you go from CA and OR to NV and AZ. Or from OK/TX to AR/LA, but that could be due to weak winds all over the Southeast. Compare to the resource map here (, and you’re certainly right about Nebraska! As Jon Stewart suggested a couple weeks ago, some states function as “the meth labs of democracy.”

      It would be interesting to see the states mapped in terms of percent harvested of theoretically available wind resource.
