Wind farms are a fast-growing source of “clean and green” power, but a key problem remains: the wind behaves erratically. On any given day, the air outdoors may move in powerful gusts or gentle breezes—or may not move at all. This leads to an uneven output from wind farms and makes it tougher for alternative energy producers to work smoothly with power grids that must send a steady flow of electricity to homes and businesses. To address these challenges, the National Science Foundation has awarded two grants totaling $6 million to Johns Hopkins researchers and their collaborators.

Large wind farms are being built around the world as a cleaner way to generate electricity, but operators are still searching for the most efficient way to arrange the massive turbines that turn moving air into power. To help steer wind farm owners in the right direction, Charles Meneveau, a Johns Hopkins fluid mechanics and turbulence expert, working with a colleague in Belgium, has devised a new formula through which the optimal spacing for a large array of turbines can be obtained.
