Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into wind farms and connected to the electrical grid.
A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore.
Crookwell Wind Farm, located at Crookwell west of Goulburn, New South Wales, consists of eight 600 kW wind turbines giving a total capacity of 4.8 MW. It was the first grid-connected wind farm in Australia when built by Pacific Power in 1998. It is now owned by Tilt Renewables.
The United Kingdom is the best location for wind power in Europe and one of the best in the world. The combination of long coastline, shallow water and strong winds make offshore wind unusually effective.
Wind power has been used as long as humans have put sails into the wind. Wind-powered machines used to grind grain and pump water — the windmill and wind pump — were developed in what is now Iran, Afghanistan, and Pakistan by the 9th century. Wind power was widely available and not confined to the banks of fast-flowing streams, or later, requiring sources of fuel. Wind-powered pumps drained the polders of the Netherlands, and in arid regions such as the American midwest or the Australian outback, wind pumps provided water for livestock and steam engines.
As of 2023, Europe had a total installed wind capacity of 255 gigawatts (GW). In 2017, a total of 15,680 MW of wind power was installed, representing 55% of all new power capacity, and the wind power generated 336 TWh of electricity, enough to supply 11.6% of the EU's electricity consumption.
Making up over 62% of the state's generated electricity in 2022, wind power is the largest source of electricity generation in Iowa. In 2020, over 34 billion kWh of electrical energy was generated by wind power. As of 2022, Iowa has over 12,200 megawatts (MW) of installed capacity with over 6,000 wind turbines, ranking second and third in the nation below Texas respectively.
Burton Wold Wind Farm is a wind farm located near Burton Latimer in the English county of Northamptonshire, UK. The farm was developed by Your Energy Ltd, is owned by Mistral Windfarms and operated by Engineering Renewables Ltd. E.ON UK is buying the electricity output of the project under a long-term power purchase agreement. The farm is spread over three hectares. It has an installed capacity of 20 MW and generate on average around 40,000,000 units of electricity annually.
The Fowler Ridge Wind Farm is a wind farm in Benton County, Indiana, near the city of Fowler, IN about 30 miles (48 km) northwest of Lafayette and 90 miles (140 km) northwest of Indianapolis. Fowler Ridge was originally developed in 2005 and 2006 by Orion Energy, LLC and Vision Energy, LLC and later sold in 2007 to BP and Dominion Resources. The project was constructed beginning in 2008 in two phases and has a nameplate capacity of 600 MW.
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.
Wind power in Belgium has seen significant advancements, starting with the generation of electricity from offshore wind farms in 2009. By 2020, the capacity of these offshore farms reached 2,262 megawatts (MW), matching the combined output of Belgium's largest nuclear reactors, Doel 4 and Tihange 3. Concurrently, the development of on-shore wind energy, which remained minimal until 2004, experienced significant growth, with installed capacity and production doubling annually from 96 MW in 2004 to 2,476.1 MW by 2021. The percentage of electricity demand met by wind grew to about 14.4% by 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.
Meadow Lake Wind Farm is an 801.25 megawatt (MW) wind farm near Brookston and Chalmers, Indiana, spreading over portions of White, Jasper, and Benton Counties. It is owned and operated by EDP Renewables North America. The facility currently has six operational phases, with 414 turbines, and is a prominent feature on both sides of Interstate 65 in western Indiana.
In 2016, Arizona had 268 megawatts (MW) of wind powered electricity generating capacity, producing 0.5% of in-state generated electricity.
Starting in 1975, NASA managed a program for the United States Department of Energy and the United States Department of Interior to develop utility-scale wind turbines for electric power, in response to the increase in oil prices. A number of the world's largest wind turbines were developed and tested under this pioneering program. The program was an attempt to leap well beyond the then-current state of the art of wind turbine generators, and developed a number of technologies later adopted by the wind turbine industry. The development of the commercial industry however was delayed by a significant decrease in competing energy prices during the 1980s.
The great majority of wind turbines around the world belong to individuals or corporations who use them to generate electric power or to perform mechanical work. As such, wind turbines are primarily designed to be working devices. However, the large size and height above surroundings of modern industrial wind turbines, combined with their moving rotors, often makes them among the most conspicuous objects in their areas. A few localities have exploited the attention-getting nature of wind turbines by placing them on public display, either with visitor centers on their bases, or with viewing areas farther away. The wind turbines themselves are generally of conventional horizontal-axis, three-bladed design, and generate power to feed electrical grids, but they also serve the unconventional roles of technology demonstration, public relations, and education.
The following outline is provided as an overview of and topical guide to wind energy:
Wind power in Rhode Island is in the early stages of development. There are several small scale wind turbine projects in the state. As of December 2013 there were 11 turbines at 10 sites in the state. In 2014, Rhode Island had 9 MW of installed wind power capacity, which quickly rose to 75 MW in 2019.
Wind power in Arkansas remains nearly untapped, with just a single wind turbine in the state. Arkansas does not have a renewable portfolio standard. Studies have concluded that while Arkansas is generally considered to have low wind resources, there are significant pockets of it throughout the state.
