Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
If you look at Shadow Casting from Wind Turbines from the Danish wind energy association, the only shadow they consider is the light shadow a turbine will project.

Also, the amount of energy extracted by a wind turbine is, as Jérôme points out, negligible compared with the amount of energy carried by the wind. The only effect I can think of is torque/vorticity generation. But if you make a wind turbine field with half the rotors spinning clockwise and half counterclockwise, the effects should cancel out.
