Impacts of climate change on global wind energy resources
An underlying assumption in conventional wind energy resource assessment methods is that the past will repeat itself. However, uncertainty about the effects of climate change directly challenges this assumption. To assess the effects of climate change on monthly-mean and annual-mean wind speeds across the globe, we combined a high-resolution (5 km) wind map with climate model simulations from the Intergovernmental Panel on Climate Change (IPCC) 4th Assessment Report (AR4). IPCC AR4 simulations were downscaled to the wind map for two emission scenarios. To estimate the uncertainty in the climate projections, several model simulations were analyzed for each emission scenario. Differences in wind speed values were calculated for both 2030 and 2050. The presentation will focus on those regions projected to experience the greatest change in wind speed and those regions where the models show the most consistent results.
