In the supply graph, the error bars show the mean (dots) and 1 s.d. (vertical lines) of daily supply during a specific period. In the demand graph, the histograms show the distribution of daily energy demand during a specific period. In the supply and demand graph, the red slashing areas show the supply–demand mismatch (SDMM). With climate change, changes in climate impact-drivers (wind speed, temperature and radiation) could force wind or solar supply to increase or be more variable at some time; fewer cold weather conditions induce less heating demand while more hot weather conditions cause more cooling demands. Consequently, the SDMM would require additional power sources for generating supply to meet demand; otherwise the SDMM would cause power outages.
