Original abstract

Abstract Emission reduction policies under the carbon neutrality process will significantly alter atmospheric composition and climate conditions, potentially affecting the distribution of renewable energy resources. Here, we use an Earth system model to assess the sensitivity of photovoltaic and wind power potential in eastern China to mitigating anthropogenic aerosols and greenhouse gases (GHGs). By comparing carbon neutrality (SSP1-1.9) relative to the high fossil fuel scenario (SSP5-8.5) under 2060 forcing levels, aerosol reductions are projected to increase solar energy availability by strengthening surface shortwave radiation and may generally enhance wind power density by reversing terrestrial stilling. In contrast, GHG mitigation modifies land-sea thermal gradients and large-scale circulation, which is associated with a decrease in wind power density. The opposing climate responses to these forcings lead to significant regional variations. Seasonally, photovoltaic potential is largely governed by GHG reductions in the warm season and by aerosol declines in the cold season. Wind power responds to both forcings in spring and summer but is primarily modulated by GHG-driven circulation changes in autumn and winter. These results indicate distinct and seasonally divergent pathways through which emission reductions influence renewable energy indicators, suggesting the importance of considering coupled climate feedbacks in the context of carbon neutrality.
