Wind power or wind energy is mostly the use of wind turbines to generate electricity. Historically, wind power has been used in sails, windmills and windpumps. Wind power is a popular, sustainable, renewable energy source that has a much smaller impact on the environment than burning fossil fuels. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission network.
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.
Vestas Wind Systems A/S is a Danish manufacturer, seller, installer, and servicer of wind turbines that was founded in 1945. The company operates manufacturing plants in Denmark, Germany, the Netherlands, Taiwan, India, Italy, Romania, the United Kingdom, Spain, Sweden, Norway, Australia, China, Brazil, Poland and the United States, and employs more than 25,000 people globally.
Hybrid power are combinations between different technologies to produce power.
The Altamont Pass wind farm is located in the Altamont Pass of the Diablo Range in Northern California. It is one of the earliest wind farms in the United States. The first wind turbines were placed on the Altamont in the early 1980s by Fayette Manufacturing Corporation on land owned by cattle rancher Joe Jess. The wind farm is composed of 4930 relatively small wind turbines of various types, making it at one time the largest wind farm in the world in terms of capacity. Altamont Pass is still one of the largest concentration of wind turbines in the world, with a capacity of 576 megawatts (MW), producing about 125 MW on average and 1.1 terawatt-hours (TWh) yearly. They were installed after the 1970s energy crisis in response to favorable tax policies for investors.
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. It manufactures wind turbines and provides onshore and offshore wind services. It is the world's second largest wind turbine manufacturer.
Wind power in Ohio has a long history, and as of 2016, Ohio had 545 megawatts (MW) of utility-scale wind power installations installed, responsible for 1.1% of in-state electricity generated. Over 1000 MW more were under construction or pending approval. Some installations have become tourist attractions. There has been a sudden increase in generating capacity, as total wind power capacity in the state was just 9.7 MW in 2010. By 2019, there were 738 MW of capacity, which generated 1.71% of Ohio's electricity.
China is the world leader in wind power generation, with the largest installed capacity of any nation and continued rapid growth in new wind facilities. With its large land mass and long coastline, China has exceptional wind power resources: it is estimated China has about 2,380 gigawatts (GW) of exploitable capacity on land and 200GW on the sea. Wind power remained China’s third-largest source of electricity at the end of 2020, accounting for 6.1% of total power generation.
In 2017 France reached a total of 13,759 MW installed wind power capacity placing France at that time as the world's eighth largest wind power nation by installed capacity, behind the United Kingdom and Canada and ahead of Italy and Brazil. According to the IEA the yearly wind production was 20.2 TWh in 2015, representing almost 23% of the 88.4 TWh from renewable sources in France during that year. Furthermore wind provided for 4.3% of the country’s electricity demand out of the 18.7% provided by renewables in 2015.
Wind power in Italy, at the end of 2015, consisted of more than 1,847 wind turbines with a total installed capacity of 8,958 megawatts. Wind power contributed 5.4% of Italy electricity generation in 2015 (14,589 GWh). Italy is ranked as the world's tenth producer of wind power as of the end of 2016. Prospects for Italian wind energy beyond 2016 were very uncertain.
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. Hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. They 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 favourable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources.
Wind Capital Group was a wind power developer founded in 2005 by Missouri native Tom Carnahan.
Wind power in New Hampshire began in 1980, with the installation of the world's first wind farm at Crotched Mountain, consisting of 20 30 kW wind turbines, although it closed decades ago. As of 2020, five wind power projects are operating in the state of New Hampshire – Lempster Mountain, which opened in 2008, Granite Reliable Wind Farm, which opened in late 2011, Groton Wind, which opened in 2012, Jericho Mountain, which opened in 2015, and Antrim Wind, which opened in 2020.
GE Power's offshore wind business is a joint venture with Alstom, created in 2015 when most of that company's other electrical power and generation assets were acquired. GE's stake in the joint venture is 50 % plus 1 share.
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.
Wind power in Virginia is in the early stages of development. In March 2015, Virginia became the first state in the United States to receive a wind energy research lease to build and operate offshore wind turbines in federal waters. As of 2019, Virginia had no utility scale wind farms.
Wind power in Maryland, which has land-based and offshore resources, is in the early stages of development. As of 2016, Maryland has 191 megawatts (MW) of wind powered electricity generating capacity, responsible for 1.4% of in-state generated electricity. Two offshore wind farm projects that will supply wind-generated power to the state are underway.
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.
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.
