Cold Northcott wind farm is a wind farm situated near the hamlet either side of the A395. It consists of 22 twin-bladed turbines (similar to Great Eppleton) with a nameplate electrical capacity of 6.6 megawatts and estimated annual output of 16 GWh. [2] The turbines began operation in April 1993 and are manufactured by Cumbrian Wind Farms. Cold Northcott wind farm is operated by a three-man crew of engineers who perform routine maintenance on the wind turbines. The turbines are manufactured by WEG. In early 2016 the 22, twin-bladed, wind turbines were out of use due to health and safety regulations. After being out of use for nearly six months, from June 2016, 20 turbines returned to use. Two turbines are still out of use due to one being struck by lightning. The other turbine, that is out of use, had a faulty gearbox. This then caused the blades to blow off during a storm, which resulted in the whole wind farm closing for nearly six months due to health and safety regulations. During the six months, the crew of engineers carried out maintenance on the operational turbines.
A windpump is a wind driven device which is used for pumping water.
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.
Small wind turbines, also known as micro wind turbines or urban wind turbines, are wind turbines that generate electricity for small-scale use. These turbines are typically smaller than those found in wind farms. Small wind turbines often have passive yaw systems as opposed to active ones. They use a direct drive generator and use a tail fin to point into the wind, whereas larger turbines have geared powertrains that are actively pointed into the wind.
Wind turbine design is the process of defining the form and configuration of a wind turbine to extract energy from the wind. An installation consists of the systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine.
Unconventional wind turbines are those that differ significantly from the most common types in use.
Siemens Gamesa Renewable Energy S.A., formerly Gamesa Corporación Tecnológica S.A. and Grupo Auxiliar Metalúrgico S.A., is a Spanish-German wind engineering company based in Zamudio, Biscay, Spain. In Spain, the company has two other main sites one in Madrid and the other one in Sarriguren (Navarre). The Services Commercial Office is located in the Parque de la Innovación de Navarra in Sarriguren. It manufactures wind turbines and provides onshore and offshore wind services. It is the world's second largest wind turbine manufacturer.
A turbine engine failure occurs when a turbine engine unexpectedly stops producing power due to a malfunction other than fuel exhaustion. It often applies for aircraft, but other turbine engines can fail, like ground-based turbines used in power plants or combined diesel and gas vessels and vehicles.
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 2nd and 3rd in the nation below Texas respectively.
A floating wind turbine is an offshore wind turbine mounted on a floating structure that allows the turbine to generate electricity in water depths where fixed-foundation turbines are not feasible. Floating wind farms have the potential to significantly increase the sea area available for offshore wind farms, especially in countries with limited shallow waters, such as Japan, France and the United States' West Coast. Locating wind farms further offshore can also reduce visual pollution, provide better accommodation for fishing and shipping lanes, and reach stronger and more consistent winds.
The wind power industry is involved with the design, manufacture, construction, and maintenance of wind turbines. The modern wind power industry began in 1979 with the serial production of wind turbines by Danish manufacturers. The industry is undergoing a period of rapid globalization and consolidation.
The environmental impact of electricity generation from wind power is minor when compared to that of fossil fuel power. Wind turbines have some of the lowest global warming potential per unit of electricity generated: far less greenhouse gas is emitted than for the average unit of electricity, so wind power helps limit climate change. Wind power consumes no fuel, and emits no air pollution, unlike fossil fuel power sources. The energy consumed to manufacture and transport the materials used to build a wind power plant is equal to the new energy produced by the plant within a few months.
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. As of 2020, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, as of 2009, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources.
Offshore wind power or offshore wind energy is the generation of electricity through wind farms in bodies of water, usually at sea. There are higher wind speeds offshore than on land, so offshore farms generate more electricity per amount of capacity installed. Offshore wind farms are also less controversial than those on land, as they have less impact on people and the landscape.
A tidal farm is a group of multiple tidal stream generators assembled in the same location used for production of electric power, similar to that of a wind farm. The low-voltage powerlines from the individual units are then connected to a substation, where the voltage is stepped up with the use of a transformer for distribution through a high voltage transmission system.
Modern United States wind energy policy coincided with the beginning of modern wind industry of the United States, which began in the early 1980s with the arrival of utility-scale wind turbines in California at the Altamont Pass wind farm. Since then, the industry has had to endure the financial uncertainties caused by a highly fluctuating tax incentive program. Because these early wind projects were fueled by investment tax credits based on installation rather than performance, they were plagued with issues of low productivity and equipment reliability. Those investment tax credits expired in 1986, which forced investors to focus on improving the reliability and efficiency of their turbines. The 1990s saw rise to a new type of tax credit, the production tax credit, which propelled technological improvements to the wind turbine even further by encouraging investors to focus on electricity output rather than installation.
On 13 July 2011, Noar Linhas Aéreas Flight 4896, a Let L-410 Turbolet passenger aircraft on a domestic service from Recife to Mossoró, Brazil, crashed shortly after take-off in the Boa Viagem neighbourhood of Recife, after suffering an engine failure. All 16 people on board were killed.
Warradarge Wind Farm is under construction 15 kilometres (9.3 mi) northeast of Warradarge, and 30 kilometres (19 mi) southeast of Eneabba in the Mid West region of Western Australia. The first of its planned 51 turbines was completed on 21 January 2020.
