The energy sector in Europe already faces impacts from climate extremes . Significant reductions and interruptions of power supply have been observed during exceptionally dry and/or hot years of the recent 20-year period, for example, in France, Germany, Switzerland and the UK during the extremely hot summer of 2018 which led to water- cooling constraints on power plants . Heating-degree days decreased and cooling- degree days increased during 1951-2014, with clearer trends after 1980 . Projected climate risks for energy supply are summarised in Figure 13.16.
