Change in Wind Renewable Energy Potential UnderStratospheric Aerosol Injections

Wind renewable energy (WRE) is an essential component of the global sustainable energyportfolio. Recently, there has been increasing discussion on the potential supplementation of this conventionalmitigation portfolio with Solar Radiation Modification (SRM). However, the impact of SRM on conventionalmitigation measures has received limited attention to date. In this study, we explore one part of this impact, thepotential effect of one type of SRM, Stratospheric Aerosol Injections (SAI), on WRE. Using hourly output fromthe Earth System Model CNRM‐ESM2‐1, we compare WRE potential under a medium emission scenario(SSP245) and a high emission scenario (SSP585) with an SRM scenario that has SSP585 baseline conditionsand uses SAI to offset warming to approximately SSP245 global warming levels. Our results suggest that SAImay affect surface wind resources by modifying large‐scale circulation patterns, such as a significant polewardjet‐shift in the Southern Hemisphere. The modeled total global WRE potential is negligibly reduced under SAIcompared to the SSP‐scenarios. However, regional trends are highly variable, with large increases and decreasesin WRE potential frequently reaching 12% across the globe with SAI. This study highlights potentialdownstream effects of SRM on climatic elements, such as wind patterns, and offers perspectives on itsimplications for our mitigation efforts.
