Beg to differ...
Buildings and bridges do not move immense masses of air, windmills do. Anything with blades wider than I am tall, with a rotational disk having a diameter of about 300 ft most certainly affects local air movement.
Beg to differ. Windmills do not move air, they are moved by air. Both buildings and windmills obstruct air flow. The amount of disruption is dependent on the area (facing the wind) and the configuration or shape of the object. Buildings, due to their more angular shape and their width, would generally be more disruptive to flow. Height, is, of course a factor. A two story house will not have as much effect as a 300 foot windmill.
Although both transfer energy out the atmosphere, neither nor both does so to a sufficient degree to affect the weather to a detectable degree.
well they do create turbulence which is movement of air
