Wind power showed potential for replacing natural gas in electricity generation on a cost basis. By 2021 wind energy produced 4872 terawatts-hour, 2.8% of the total primary energy production [51] and 6.6% of the total electricity production. [52] Technological innovations continue to drive new developments in the application of wind power.
Wind energy penetration is the fraction of energy produced by wind compared with the total generation. Wind power's share of worldwide electricity usage in 2021 was almost 7%, [55] up from 3.5% in 2015. [56] [57] There is no generally accepted maximum level of wind penetration.
Wind Power Density (WPD) is a quantitative measure of wind energy available at any location. It is the mean annual power available per square meter of swept area of a turbine, and is calculated for different heights above ground. Calculation of wind power density includes the effect of wind velocity and air density. [25]
James Blyth (4 April 1839 – 15 May 1906) was a Scottish electrical engineer and academic at Anderson's College, now the University of Strathclyde, in Glasgow.He was a pioneer in the field of electricity generation through wind power and his wind turbine, which was used to light his holiday home in Marykirk, was the world's first-known structure by which electricity was generated from wind power.
India has the fifth largest installed wind power capacity in the world. [96] As of 31 March 2014, the installed capacity of wind power was 21136.3 MW mainly spread across Tamil Nadu state (7253 MW). [97] [98] Wind power accounts nearly 8.5% of India's total installed power generation capacity, and it generates 1.6% of the country's power.
The environmental impact of electricity generation from wind power is minor when compared to that of fossil fuel power. [62] 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. [63]
Latvia's wind capacity grew by 75%, the largest percent increase in 2022. [3] In November 2018, wind power generation in Scotland was higher than the country's electricity consumption during the month. [5] Wind power's share of worldwide electricity usage in 2023 was 7.8%, up from 7.3% from the prior year.
Middelgrunden offshore wind park, 3.5 km outside Copenhagen.When built in 2000, it was the world's largest. [1]Denmark was a pioneer in developing commercial wind power during the 1970s, and today a substantial share of the wind turbines around the world are produced by Danish manufacturers such as Vestas—the world's largest wind-turbine manufacturer—along with many component suppliers.
