How do wind turbines work?

Every 24 hours, wind generates enough kinetic energy to produce roughly 35 times more electricity than humanity uses each day. And unlike coal or oil, this resource is totally renewed each day. So how can we harness this incredible amount of energy, and is it possible to create a world powered entirely by wind? Rebecca Barthelmie and Sara Pryor dig into the science of wind turbine technology. [Directed by Gavin Edwards, Movult, narrated by Alexandra Panzer, music by Stephen LaRosa].
