The kinetic energy of the wind turns the turbine blades.
A shaft running from the blades to a gearbox (nacelle) spins round as the blades turn.
The gears use the slow-spin of this shaft to make a second shaft spin much faster.
This spinsmagnets inside a generator. The magnets spin very fast past coils of copper wire making electricity start to flow through the wire. Kinetic energy is changed to electrical energy
Electricity travels through cables to the National Grid
