Estimating the wind resource available around the world is a major component of the development of wind energy technology. Not only do we need to know how much wind there is to meet the energy demand, but we also need to know what specific locations have the most wind when compared to others. So what if I told you that the way many scientists and engineers do this estimation is inherently flawed?

It may surprise you to know that most wind resource estimations aren’t based on direct measurements, because we don’t have many. Most of our wind data come from surface measurements – airports, ocean weather buoys, even most satellite wind measurements are surface based. The problem is, wind turbines don’t depend on wind at the surface. They can be anywhere from 20 to 100 meters high, and the wind speed up there can be radically different than whatever…
