Reduced surface wind speeds during 1979-2016  support projected trends in decreasing onshore wind energy potential. Seasonal changes may result in reductions in many areas in summer  and increases in most of NEU during winter. Increasing probabilities and persistence of high winds over the Aegean and Baltic seas  could create new opportunities for offshore wind. The future configuration of the wind fleet will affect the spatial and temporal variability of wind power production . Total backup energy needs in Europe could increase by 4-7% by 2100  with potentially larger seasonal changes .
