There are very few if any Vertical-Axis Wind Turbines (VAWTs) under development today. It’s unlikely that there are any in commercial service anywhere in the world. The technology has reached a dead end. For why that is so, see my most recent book Wind Energy for the Rest of Us.
Most of the turbines pictured here were inoperative when the photo was taken. Many of them–if not all–were removed years ago. Of the few that were operating when the photo was taken it is noted in the caption.
