The United States Energy Information Administration (“EIA”) issued an October 26th report providing 2015 data on the percentage of energy generated by wind in the United States.
The EIA report notes that in 2015 eleven states generated at least 10% of their total electricity from wind.
The states generating at least 10% of their total electricity from wind included:
- Iowa (31%)
- South Dakota (25%)
- Kansas (24%)
- Oklahoma (18%)
- North Dakota (18%)
- Minnesota (17%)
- Idaho (16%)
- Vermont (15%)
- Colorado (14%)
- Oregon (11%)
- Maine (10%)
Wind accounted for 4.7% of net United States electric power generation. The report noted that wind’s share of total United States electricity generation has risen every year since 2001.
EIA concludes that the increase of wind power in the United States has been driven by:
- Technological changes
- Improved wind technology
- Increased access to transmission capacity
- Federal Production Tax Credit (FPTC)
- Investment Tax Credit (ITC)
- State-level Renewable Portfolio Standards (RPS)
