Why Are Wind Turbines So Skinny at Lachlan Stephens blog

Why Are Wind Turbines So Skinny. Wind turbines extract energy from the air by slowing it down. The key to the answer is that contrary to popular belief, modern windmill blades don't spin because they are pushed by the wind; As many as 90 percent of the turbines in use now have three blades. The size of the turbine, so the swept area of the blade, the circle within which the rotor rotates. And then the other thing is the amount that the air is deflected. A combination of structural and economic considerations drives the use of three slender blades on most wind turbines—using one or two blades means more complex structural dynamics, and more. Real wind turbines are not designed like a fan, they are designed like a wing. Wings on most airplanes are long and relatively skinny. If you have wider blades you slow down the air more. However that slow air still needs to go. The wind turbines that generate electricity seem to have just three blades, or sometimes two. The bigger that is, the more air the turbine interacts with, the more power you get.
