The windmills at Kinderdijk in the village of Kinderdijk, Netherlands is a UNESCO World Heritage Site. A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, by tradition specifically to mill grain (), but in some parts of the English-speaking world, the term has also been extended to encompass windpumps, wind turbines, and other applications.
When a turbine is mounted on a rooftop the building generally redirects wind over the roof and this can double the wind speed at the turbine. If the height of a rooftop mounted turbine tower is approximately 50% of the building height it is near the optimum for maximum wind energy and minimum wind turbulence.
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.
A diagram of a panemone whose wind-catching panels are arranged to turn edge-on to the wind when moving against the wind's thrust, and side-on when moving downwind to harness the wind's motion. A panemone windmill is a type of vertical-axis wind turbine. It has a rotating axis positioned vertically, while the wind-catching blades move parallel ...
The first wind turbine. William Kamkwamba (born August 5, 1987, in Kasungu, Malawi), is a Malawian inventor, engineer, and author. He gained renown in his country in 2001 when he built a wind turbine to power multiple electrical appliances in his family's house in Wimbe, 23 kilometres (14 mi) east of Kasungu, using blue gum trees, bicycle parts, and materials collected in a local scrapyard.

An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, [1] thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, [2] or the need for slip rings or yaw mechanism. An electrical generator may be on the ground ...
