Technical Considerations
Wind turbines convert the energy of wind movement (kinetic energy) into mechanical energy. This mechanical energy is then converted into electricity.
There are three principles governing the amount of energy available from the wind: (1) the power available to the turbine is proportional to the wind speed cubed; (2) the power available is directly proportional to the swept area of the blades and (3) Betz' law determines the maximum theoretical efficiency of wind generators is 59%.
The load factor (or capacity factor) for South Australian wind farms is usually in the range 32-38%. This means that a wind farm could typically produce between 32 and 38% of its nameplate capacity averaged over a year.

Famous quotes containing the word technical:
“Where there is the necessary technical skill to move mountains, there is no need for the faith that moves mountains.”
