Living out in west Texas, we have hundreds of wind turbines on the horizon in any given direction. Some days (like today) you could drop a feather straight down without it moving, however all the turbines are spinning. Isn’t that counterproductive?

Hi. There may not be appreciable wind at ground level at the same time there would be a 10-15 knot breeze that would spin the turbine.
There is also a lot of momentum with those turbines that will keep them spinning for hours to dissipate the energy if the wind is actually zero. They have bearings inside the “guts” of the windmill that assists the spinning by reducing the friction that normal windmills do not have.
