Almost all wind turbines producing electricity consist of specialist designed, highly engineered blades which rotate around a horizontal hub. The hub is connected to a generator where the electricity is created. More wind means higher electricity production, but more important is the average speed than the maximum speed at any given moment. The bigger the rotor diameter, the greater the output and the higher the tower, the more wind the turbine catches.
It is worth noting that a single 2.5 MW turbine will typically generate an incredible 6.5 million kWh of electricity each year. That’s enough to meet the annual needs of over 1,400 households.
