Why do wind turbines continue to spin even when there’s no wind?

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?

Are you dropping that feather from two hundred feet up? That’s how high those turbines are mounted. That could be it. In places with tall trees you’ll notice the treetops swaying even if you don’t feel any wind on the ground.
