Core Viewpoint - Climate change is likely to exacerbate the frequency and severity of supply-demand imbalances in high penetration wind and solar power systems in the future [2][4]. Group 1 - The research team utilized a scheduling optimization model to assess the potential hourly cost increases due to climate change under fixed and high penetration rates of wind and solar energy [4]. - During extreme periods, which are defined as the top decile of hourly costs, the study predicts that costs may rise significantly in most countries, primarily due to increased investment needs for flexible energy capacity [4]. - In the SSP126 scenario, it is anticipated that 47 countries will see an average hourly cost increase of over 5% during extreme periods, collectively accounting for approximately 43.5% of future global electricity supply, with the highest increase reaching 23.7% [4]. Group 2 - The research findings provide critical insights for constructing future electricity systems that are both climate-resilient and cost-effective [5].
