A wind-driven wheel is also known as a windmill, wind turbine, or wind generator. Windmills are typically used for grinding grain or pumping water, while wind turbines are used to generate electricity. Other synonyms for a wind-driven wheel include wind pump, wind-powered device, and aerogenerator. In some cases, a wind-driven wheel may also be referred to as a wind charger or wind-driven power plant. Regardless of the specific terminology used, wind power remains an increasingly popular and sustainable form of energy production, with the potential to reduce reliance on non-renewable sources like coal and oil.
