The generator in the nacelle of the turbine typically produces alternating current (AC) electricity.
The electricity produced by the wind is sent down a thick cable inside the tower, and then via underground cables to a substation.
At the substation, the voltage is modified so it can be fed into the power grid and transported to electricity consumers.
In general terms this is how the electricity produced by wind is able to power electrical appliances in our homes, schools, hospitals and offices.
