All electricity generators (commercial) work the same way – spin a conductor inside a magnetic field and you generate a flow or electric charges. In hydroelectric plants, water flow spins giant turbines; in thermoelectric, whether gas, nuclear, coal or oil, heated fluid (water usually) spins the turbine. In wind turbines, the wind does . Big giant blades, just like in a windmill are pushed by the flow of fluid (air); they transfer the motion to the axis that through gears is transmitted to the rotor.
