This article shows a high quality video animation explaining in an easy to understand demonstration and language how wind power actually works. Great and usefull high level information for the excited newcomer to wind power.
1.) Modern wind turbines start generating electricity at a wind speed of approximately 9mph. As wind speed increases so does electrical output. At storm force over 55mph, they cut out to prevent damage to the turbine
2.) A Yaw Drive turns the turbine to face directly into the wind. The wind then turns the wind-turbine blades causing the rotor to turn.
3.) The rotor turns a shaft and this speed is increased by a gear box. This turns a generator, which uses magnetic fields to convert the rotational energy into electricity.
4.) The electricity generated, passes down through the cables inside the tower to a transformer which converts the low voltage to high voltage.
5.) Clean electricity is distributed, via the grid, to homes, businesses and public buildings.

windturbine
A good introduction about how a wind turbine works. It will be better if there are related pictures.
