Energy demand is projected to display regional differences in response to warming beyond 2℃ GWL, with a the significant southwest-to- northeast decrease of heating-degree days by 2100 , and a smaller north-to-south increase of cooling-degree days . Under the present population numbers, total energy demand would decrease in almost all of Europe, whereas it could increase in some countries  when considering Eurostat's population projections . There is medium confidence that peak load will increase in SEU and decrease in NEU . Beyond 2ºC GWL, a shift of peak load from winter to summer in many countries is possible . Together with water-cooling constraints for thermal power, this change in load may challenge the stability of electricity networks during heatwaves . Technological factors, increased electricity use and adaptation influence significantly the temperature sensitivity of electricity demand and consequently risks . Potential power curtailments or outages during climatic extremes may increase electricity prices .
