Wind farms, also referred to as wind parks, wind power plants, and wind power stations are groups of wind turbines in the same location used to produce electricity on a commercial level. Wind farms supply power to an electrical grid and can be onshore or offshore. The largest wind farms are located in China, India, and the United States.
