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.
The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period. The capacity factor can be calculated for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy, such as wind or the sun. The average capacity factor can also be defined for any class of such installations, and can be used to compare different types of electricity production.
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. By 2023, the UK had over 11 thousand wind turbines with a total installed capacity of 28 gigawatts (GW): 14 GW onshore and 14 GW offshore, the sixth largest capacity of any country. Wind power generated about 25% of UK electricity, having surpassed coal in 2016 and nuclear in 2018. It is the largest source of renewable electricity in the UK.

Solar power is a fast-growing industry in Australia. As of March 2023, Australia's over 3.44 million solar PV installations had a combined capacity of 30,465 MW photovoltaic (PV) solar power, of which at least 3,953 MW were installed in the preceding 12 months. In 2019, 59 solar PV projects with a combined capacity of 2,881 MW were either under construction, constructed or due to start construction having reached financial closure. Solar accounted for 12.4% of Australia's total electrical energy production in 2021.
Wind power became a significant energy source within South Australia over the first two decades of the 21st century. In 2015, there was an installed capacity of 1,475 MW, which accounted for 34% of electricity production in the state. This accounted for 35% of Australia's installed wind power capacity. In 2021, there was an installed capacity of 2052.95 MW, which accounted for 42.1% of the electricity production in the state in 2020.
The Emu Downs Wind Farm is a 79.2 MW wind farm in Western Australia. It was a 50:50 joint development between Griffin Energy and Stanwell Corporation. The site is approximately 200 kilometres north of Perth, near Cervantes. Construction of the $180 million project commenced in November 2005, and the project was commissioned in October 2006.
Musselroe Wind Farm is a wind farm at Cape Portland, Tasmania, Australia. It was the third wind farm built in the state, following the Bluff Point and Studland Bay Wind Farms.
Coopers Gap Wind Farm is a 453 megawatt wind farm in the Western Downs and South Burnett regions of Queensland, Australia. It is located approximately 175 km north-west of the state capital Brisbane, and 50 kilometres south-west of Kingaroy and 65 km north of Dalby. When construction was announced to be completed on 30 April 2020, it became the largest wind farm in Australia. This record was held until 10 December 2020 when the Stockyard Hill Wind Farm in Victoria was completed.
The Macarthur Wind Farm is a wind farm located in Macarthur, Victoria, Australia, near Hamilton, 260 km west of Melbourne. It is on a 5,500 ha site which has an installed capacity of 420 megawatts (MW). Based on a capacity factor of around 35%, it is estimated that the long-term average generation will be approximately 1,250 GWh per year. Its actual capacity factor is much lower, with a historical average of 26.29% since 2013.
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.
The Taralga Wind Farm is a wind farm located near Taralga, New South Wales. Owned by Pacific Blue, it commenced operation in 2015.
Solar River Project is a proposed photovoltaic power station planned to be built near Robertstown in South Australia. The project received development approval from the Government of South Australia in June 2018 and was expected to start construction early in 2019. However, as of November 2021, the project was still proposed to be constructed, but work on site was not expected until at least the second half of 2022.
The Murra Warra Wind Farm is one of Australia's largest wind farms. Located on the plains of north-western Victoria, approximately 25 kilometres (16 mi) north of the city of Horsham, it consists of 99 wind turbines with a maximum tip height of 220m.
