You are missing my point about efficiency and how it's calculated with regards to wind turbines. The fuel is free and non polluting so doesn't matter.
What you appear to mean is how cost effective they are, as in cost to build and run compared to amount of power produced and how long before they have payed for themselves and are making money for the owner of them.
Talking about subsidies, many comment on wind power subsidies. This 2 year ol newspaper article from The Guardian states that wind power subsidies are dwarfed by fossil fuel subsidies
Wind power still gets lower public subsidies than fossil fuel tax breaks | Environment | The Guardian
