How do offshore wind turbines work? | Ørsted

To capture wind energy, the top part of the turbine is turned to face the wind, the three blades are set at exactly the right angle, and the movement of the air past them causes them to rotate. Within the nacelle – the non-rotating part on top of the turbine – the blades'' rotation is passed through a drive shaft, often via gear box, to turn magnets inside a coil of wire.
