Wind Energy
how does wind energy work? The wind blows on the blades and makes them turn. The blades turns a shaft inside the nacelle (the box at the top of the turbine) The shaft goes into a gearbox which increases the rotation speed enough for... The generator, which uses magnetic fields to convert the rotational energy into electrical energy. These are similar to those found in normal power stations. The power output goes to a transformer, which converts the electricity coming out of the generator at around 700 Volts (V) to the right voltage for distribution system, typically 33,000 V. The national grid transmits the power around the country.
