Extended Data Fig. 6: Effectiveness of strategies to reduce climate-driven increase in hourly costs (%) at the 50% likelihood level under the SSP245 scenario.

The digits represent the 50th percentile of relative cost reductions (%) across dispatch model simulations with climate model ensembles in 26 major countries, calculated as the difference between average hourly costs in the baseline and after implementation of one or more strategies under future climate (2056–2060).
