Recently, there has been increasing discussion on the potential supplementation of this conventional mitigation portfolio with Solar Radiation Modification (SRM). However, the impact of SRM on conventional mitigation measures has received limited attention to date. In this study, we explore one part of this impact, the potential effect of one type of SRM, Stratospheric Aerosol Injections (SAI), on WRE. Using hourly output from the 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 conditions and uses SAI to offset warming to approximately SSP245 global warming levels. Our results suggest that SAI may affect surface wind resources by modifying large-scale circulation patterns, such as a significant poleward jet-shift in the Southern Hemisphere. The modeled total global WRE potential is negligibly reduced under SAI compared to the SSP-scenarios. However, regional trends are highly variable, with large increases and decreases in WRE potential frequently reaching 12% across the globe with SAI. This study highlights potential downstream effects of SRM on climatic elements, such as wind patterns, and offers perspectives on its implications for our mitigation efforts. *Key Points* Stratospheric Aerosol Injections do not fully compensate for atmospheric circulation changes from climate change but create new dynamics Total global wind energy potential is negligibly reduced under Stratospheric Aerosol Injections but regional trends tend to vary substantially Results are based on hourly output from CNRM-ESM2-1. Changes are likely to be larger in other GeoMIP models in the northern hemisphere *Plain Language Summary* Wind renewable energy (WRE) is a pivotal element of the global transition toward sustainable energy. Recently, there has been a surge of interest in Solar Radiation Modification (SRM) as a potential means of managing climate impacts, but its effects on existing strategies like WRE have not been much addressed in the current literature. This research examines the potential impact of one type of SRM, Stratospheric Aerosol Injections (SAI), on WRE potential. An Earth System Model is used to compare WRE potential under three climate scenarios: one with moderate emissions, one with high emissions and one where SAI is used to reduce warming in the high-emission scenario to match the moderate-emission global warming level. The findings suggest that SAI may result in a minimal reduction in long-term global mean WRE potential. However, the effects vary considerably by region and season, with areas experiencing changes in WRE potential that frequently reach approximately 12%. This research highlights the potential for SAI to exert complex effects on wind patterns, which could influence the future of renewable energy strategies. *Source: AGU* -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
