Today, wind power is generated almost completely using wind turbines, generally grouped into wind farms and connected to the electrical grid. In 2025, wind supplied about 2,700 TWh of electricity, which was over 8% of world electricity. As of 2024, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 1,136 gigawatts of power, with 117 GW added each year.
