I live near a ton of windmills in the hills 50 miles east of SF. In highschool we would go to them, although technically illegal. You stand on the ground, with the windmill churning away 100 feet above your head. It would obviously still be windy as hell near the ground. I have a feeling that if you had 10 units of wind, and placed windmills in a linear line for a linear mile as tightly as you could... Just a small distance away you would still have 9.99 units of wind. The density of wind capture devices relative to the overall mass of wind in the general area is so low I don't think you could make a big difference. If anything, I'd worry more about solar farms that cause massive heat soak by placing black solar panels near ground level, where instead it would be light color dry dirt and dry greens that are a lot more reflective.
