Wind energy generation by state

How your state stacks up among others in generating electricity from wind

For business

When you think of Texas energy, you probably think about oil derricks and natural gas pumps and the like. But wind turbines increasing have become part of the landscape of the Lone Star State – so much so that Texas leads the nation, by far, in electricity generated by wind. A ChooseEnergy.com® analysis of the latest data from the U.S. Energy Information Administration shows just how much the state dominates.

Texas produced nearly 30 percent of the nation’s electricity generated by wind in May. That’s well more than triple the amount from the next state, Iowa. Following are the top states for the month, measured in thousand megawatt hours:

State May generation % of U.S. total
Texas 8,398 29.8
Iowa 2,516 8.9
Oklahoma 2,318 8.2
Kansas 1,945 6.9
California 1,427 5.1
Illinois 1,319 4.7
Colorado 1,163 4.1
North Dakota 1,061 3.8
Minnesota 955 3.4
Oregon 707 2.5

Nationally, electricity generation from wind decreased about 4.6 percent from April to May. Of the 37 states with significant wind generation, 28 showed losses during the period.

Following is a list of the states with significant wind energy generation, the amounts (in thousand megawatt hours) produced in April and May, and the percentage increase or decrease during the period:

How does the month compare with the previous year?

Total wind generation increased 8.5 percent nationally from May 2019 to May 2020. Generation increased by the greatest percentage in South Dakota. Following are the 10 states in which the production of electricity from wind increased by the greatest percentage:

State May 2020 May 2019 % change
South Dakota 436 235 85.5
North Carolina 55 40 37.5
New Hampshire 43 34 26.5
Colorado 1,163 923 26.0
Missouri 282 230 22.6
North Dakota 1,061 868 22.2
West Virginia 179 151 18.5
Illinois 1,319 1,113 18.5
Montana 215 182 18.1
Iowa 2,516 2,171 15.9

The largest decline was in Arizona. Following are the states in which the production of electricity fell from May 2019 to May  2020:

State May 2020 May 2019 % change
Arizona 52 62 -16.1
Nevada 30 35 -14.3
California 1,427 1,621 -12.0

Indiana 507 511 -0.8

Which states get the highest percentage of their power from wind?

The answer can vary from month to month. For May, Iowa took the top spot on the list, getting two-thirds of its electricity from wind. Following are the 10 states that relied on wind energy for the largest percentage of their electricity generation.

State % from wind State % from wind
Iowa 59.5 Colorado 29.7
Kansas 48.1 New Mexico 25.5
Oklahoma 36.0 Minnesota 24.8
South Dakota 35.0 Maine 24.3
North Dakota 33.5 Nebraska 22.1
