How does a wind turbine make electricity? The wind turns the blades, which spin a gear shaft in the nacelle at the top of a turbine. The shaft is connected to an electric generator and makes it turn to produce electricity. The electricity is then taken away through a cable in the mast and underground cables to the substation, where it is fed into the electricity transmission grid. The turbine is constantly monitoring the wind through the anemometer mounted on the nacelle. The nacelle then rotates to make sure the blades are always facing the wind.
