Power available to <strong>the</strong> wind<br />
turbine increases with wind<br />
speed cubed.<br />
The energy available to <strong>the</strong><br />
wind turbine is virtually all<br />
below 20m/s (Example<br />
based on 7m/s annual mean<br />
wind speed)<br />
Challenge is to be efficient at<br />
low wind speeds, and shed<br />
power and loads in strong<br />
winds. Solution must be<br />
totally reliable.
