Wind turbine efficiency definition and comparing it to

Wind turbine efficiency is a useful parameter for comparing performance of wind turbines to other wind turbines. Comparisons of wind turbine efficiency to the efficiency of other forms of power generation is meaningless and misleading (which is worse than meaningless). Though that hasn''t stopped people from doing it all over the internet.
