In an effort to figure out the best areas to harvest wind energy, scientists from NASA’s Earth Science Division have used several years of QuikSCAT satellite data to produce some pretty awesome looking wind power density maps. According to them, if the areas with high wind power–an average wind of greater than 30 knots (45 miles an hour)—were tapped, they could potentially supply 10 to 15 percent of the world’s energy needs.
