Turbulent Air Reduces Wind Energy: Filed under: Energy News

Wind results from unequal temperatures. This can be a vertical wind or a horizontal one. Vertical winds are responsible for the sometimes rapid rise or fall of planes. The same turbulent conditions that might require you to “return to your seat and fasten your seatbelt” makes wind turbines less efficient. Additionally, different horizontal wind speeds at different heights, also known as wind shear, can put stress on large turbine blades. Studies have been measuring horizontal wind speeds and their duration to determine the wind energy potential of an area for awhile. Now, a new study concludes that unstable atmospheric conditions can reduce wind turbine performance by an average of 15%. The research was conducted by Sonia Wharton of the Lawrence Livermore National Laboratory (California) and Julie Lundquist from the University of Colorado. Obstructions Turbulence can also ...
