They do that by effectively slowing down the wind. though, which is going to have an effect on the downwind side. It's also worth noting that wind turbines can't be used in isolation (e.g. as your sole electricity source)--because you can't predict how strong the wind is, and thus how fast the turbines will spin, they have to use induction generators in them, and those require an existing electricity supply. If you didn't supply electricity to a wind turbine it would generate nothing.
