According to the United States Energy Information Administration (EIA), 40 US states had utility-scale wind power facilities in 2016, most of which were located in Texas (20.2 GW), Iowa (6.8 GW), Oklahoma (6.6 GW), California (5.7 GW), and Kansas (4.5 GW). These five states accounted for around 55% of the total US wind power generation in 2016 (58 TWh in Texas, 20 TWh each in Iowa and Oklahoma and 14 TWh each in California and Texas). Texas has one of the largest wind parks in the world, the 735 MW Horse Hollow Wind Energy Center, consisting of 420 wind turbines. The largest onshore turbines in the United States are located in Texas, with average capacities of 4 MW each.
Over the past decade, wind turbines in the US have grown both in terms of capacity and height. The largest current installed US offshore turbines have an operating generating capacity of 6 MW and belong to the Block Island Wind Park (Rhode Island). Besides, the average height of the turbines has been increasing and since 2012, most of the new turbines installed had an average height of 280 feet (about 80 m).
