A study by a team from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences and their collaborator from Purdue University has revealed a widespread decline in wind energy resources over the Northern Hemisphere. Using station observation data, the researchers found that approximately 30%, 50% and 80% of the stations lost over 30% of the wind power potential since 1979 in North America, Europe, and Asia, respectively. . . .

The study also revealed that global climate models (GCM) cannot replicate long-term changes on wind energy, indicating wind energy projections based on GCM simulations should be used with careful consideration to the model performance.

  • Our study is one of the first comprehensive assessments of the GCM-based winds against surface observations over multiple continents. We found that the decline of wind energy is a widespread and potential global phenomenon. In addition, the finding that the climate models have a notable deficiency in simulating wind energy is an important conclusion that needs further attention.
