Wind power in California had initiative and early development during Governor Jerry Brown's first two terms in the late 1970s and early 1980s. The state's wind power capacity has grown by nearly 350% since 2001, when it was less than 1,700 MW. In 2016, wind energy supplied about 6.9% of California's total electricity needs, or enough to power more than 1.3 million households. Most of California's wind generation is found in the Tehachapi area of Kern County, California, with some large projects in Solano, Contra Costa and Riverside counties as well. California is among the states with the largest amount of installed wind power capacity. In recent years, California has lagged behind other states when it comes to the installation of wind power. It was ranked 4th overall for wind power electrical generation at the end of 2016 behind Texas, Iowa, and Oklahoma. As of 2019, California had 5,973 megawatts (MW) of wind power generating capacity installed.
The U.S. state of Oregon has large wind energy resources. Many projects have been completed, most of them in rural Eastern Oregon and near the Columbia River Gorge. Wind power accounted for 12.1% of the electricity generated in Oregon in 2016.
The Titan Wind Project is 25MW wind farm which had a proposed expansion to 5,050 MW, formerly known as Rolling Thunder, based in South Dakota. The project developers, Clipper Windpower and BP Alternative Energy, expected to build Titan in several phases and, when completed, it would have been one of the largest wind farms in the world.
Wyoming has one of the highest wind power potentials of any state in the United States. In 2019, Wyoming had wind powered electricity generating capacity of 1,589 MW, which produced 9.85% of its electric generation, with an additional 3,753 MW under construction. However, the wind generation in that year was Wyoming's third-lowest in the 2010s. By 2020, wind capacity increased to 2738 MW and 8448 gigawatt-hours of electricity were produced from wind in 2021, more than double 2019 production. Additional wind capacity and needed transmission lines are under construction or planned, despite political headwinds from Wyoming's strong coal and oil sectors.
At the end of 2016, the installed capacity for wind power in Minnesota was 3,500 megawatts (MW). Wind power generated nearly 18 percent of Minnesota’s electricity in 2016, ranking sixth in the nation for wind energy as a share of total electricity generation.
Wind power in Illinois provided nearly 10% of the state's generated electrical power in 2020 powering 1,231,900 homes. At the end of 2020, Illinois had 6,300 megawatts (MW) of wind power installed, ranking fifth among states for installed wind turbine capacity. An additional 1,100 MW of wind power was under construction across the state at the end of 2020.
Wind power in Indiana was limited to a few small water-pumping windmills on farms until 2008 with construction of Indiana's first utility-scale wind power facility, Goodland with a nameplate capacity of 130 MW. As of March of 2024, Indiana had a total of 2,743 MW of wind power capacity installed, ranking it 12th among U.S. states. Wind power was responsible for 4.8% of in-state electricity production in 2016.
GE Wind Energy is a branch of GE Renewable Energy, a subsidiary of General Electric. The company manufactures and sells wind turbines to the international market. In 2018, GE was the fourth largest wind turbine manufacturer in the world.
In 2016, Arizona had 268 megawatts (MW) of wind powered electricity generating capacity, producing 0.5% of in-state generated electricity.
The U.S. state of Massachusetts has vast wind energy resources offshore, as well as significant resources onshore. The 2016 update to the states's Clean Energy and Climate Plan had a goal of reducing 1990 baseline greenhouse gas emissions levels by 25% by 2020. Current goals include installing 3,500 megawatts (MW) of offshore wind power in the state by 2035. However, as of Q4 2021 the state had only 120 MW of wind powered electricity generating capacity, responsible for generating 0.9% of in-state electricity production. The state has awarded contracts to two offshore projects, the 800 MW Vineyard Wind project and 804 MW Mayflower Wind project. Construction began on the Vineyard Wind 1 project on November 18, 2021, after a long fight for approval. Commonwealth Wind was selected for development in 2021, but the developer has attempted to cancel the project due to increased costs. There are eight projects planned for off the southern coast of Massachusetts, though some will deliver power to Rhode Island, Connecticut, and New York.
REG WindPower is a renewable energy company, in the United Kingdom.
Wind power in Michigan is a developing industry. The industrial base from the automotive industry has led to a number of companies producing wind turbine parts in the state. The development of wind farms in the state, however, has lagged behind. In January 2021, there were a total of 1,481 wind turbines in the state with a nameplate capacity of 2,549 MW. The nameplate total exceeded 2,000 MW when Pine River came online in March 2019. Wind provided 4.2% of the state's electricity in 2016.
The state of South Dakota is a leader in the U.S. in wind power generation with over 30% of the state's electricity generation coming from wind in 2017. In 2016, South Dakota had 583 turbines with a total capacity of 977 megawatts (MW) of wind generation capacity. In 2019, the capacity increased to 1525 MW.
The U.S. State of Oklahoma has high potential capacity for wind power in the western half of the state. In 2021, Oklahoma's installed wind generation capacity was almost 10,500 megawatts, supplying over 40% of the state's generated electricity and 85% of Oklahoma's total generating capacity from all renewable resources.
Wind power in Hawaii has the potential to provide all of the electricity generation in the electricity sector in Hawaii. The 132 commercial wind turbines in the state have a total capacity of 236 MW. In 2015, wind turbines produced 6.4% of Hawaii's electricity. In 2012, Hawaii generated 367 million kWh from wind power.
The U.S. Department of Energy has determined that West Virginia has significant wind power development opportunities, with a potential of 69 gigawatts. As of the start of 2020, there were 376 wind turbines in operation in West Virginia with a generating capacity of 686 megawatts (MW) and responsible for 2.7% of in-state electricity production. An additional 56 MW was under construction.
Wind power in North Carolina is found along the coastal areas in the east and mountain regions in the western part of the state. The state has significant offshore wind resources. In 2015, small scale wind turbine projects were found throughout the state. In 2016, North Carolina's first large scale wind project, and the first in the southeastern U.S., was completed near Elizabeth City.
Wind power in Nebraska remains largely untapped in comparison with its potential. In the Great Plains, with more than 47,000 farms and open skies it ranks near the top in the United States in its ability to generate energy from wind. As of 2015, the state had not adopted a renewable portfolio standard. Omaha Public Power District (OPPD) is one of the state's largest purchasers of wind energy.
