How do wind turbines work? | Rebecca J. Barthelmie and Sara C. Pryor
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...
