Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. 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. Together with solar power and hydroelectric power, wind power is one of the most widely utilized forms of renewable energy.

A wind turbine generates electricity by using the kinetic energy of wind to spin its blades, which are connected to a rotor. The generator then converts this mechanical energy into electrical energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The stronger the wind blows. . Wind energy has become one of the most powerful symbols of sustainable progress, capturing nature's invisible force and transforming it into electricity that fuels homes, industries, and cities around the world. This technology represents a significant pathway in the global transition toward renewable energy generation.
