FOR IMMEDIATE RELEASE
May 2, 2011
BLOOMINGTON, Ind. -- The production of wind energy in the U.S. over the next 30-50 years will be largely unaffected by upward changes in global temperature, say a pair of Indiana University Bloomington scientists who analyzed output from several regional climate models to assess future wind patterns in America's lower 48 states.
Their report -- the first analysis of long-term stability of wind over the U.S. -- appears in this week's Proceedings of the National Academy of Sciences Early Edition.
"The greatest consistencies in wind density we found were over the Great Plains, which are already being used to harness wind, and over the Great Lakes, which the U.S. and Canada are looking at right now," said Provost's Professor of Atmospheric Science Sara Pryor, the project's principal investigator. "Areas where the model predicts decreases in wind density are quite limited, and many of the areas where wind density is predicted to decrease are off limits for wind farms anyway."

Results from the Canadian regional climate model (CRCM) show the difference in energy density (power in the wind) between 2041-2062 and 1979-2000. If the grid cell is red the future energy density is higher than the historical values and if it is blue the future energy density is lower than the historical values. Solid squares show differences above 10% while the open symbols show changes of plus or minus 5-10%. The white grid cells show that the future lies within 5% of the historical values.
