To provide power on a national scale, a large number of
windmills will have to be deployed in wind farms or arrays because
the output of individual machines is relatively small. Within an
array, some windmills will be faced with the wakes generated by
others. This interaction leads to a loss of power relative to upwind
turbines and changes in the wind loading across the turbine blades. [Continues.]
