The wind pushes the blades (rotor); the rotor turns the generator; the generator makes electricity.

How much electricity does it produce?
That depends on a lot of variables like rotor diameter, tower height, average wind speed at the location, etc.

You can monitor the current energy output from the UUAA wind turbine and the UUAA solar panels on this web site.
