Nobody owns the air, for example, and nobody controls which way it blows.
Ultimately, wind energy is derived from solar energy. A wind farm is what the electric power industry calls a cluster of wind turbines that generate electricity for a power grid. Wind energy resources for a specific area are usually assumed to be relatively constant, but this may not always be the case. Short-term wind speed variability has been modeled and explored, he said, but variability in wind statistics from year to year and changes in daily and yearly cycles have largely been ignored. Robeson has studied how wind energy has varied in the past in several promising locations, with the goal of better understanding how wind resources may vary in the future.
