In case of slovenia in 2014, something happened, that has 'never' happened before (atleast not in living memory), and this: https://www.postojna.si/Datoteke/Slike/Novice/123958/l_12395... was the affect on power infrastructure. People who could heat their houses with eg. wood or gas, stayed warm, the ones who only had electricity-powered devices (for heat, cooking,..) were screwed, and had to get help from others. If you forbid alternatives, you're cold, and all your neighbors are cold too, and rebuilding after such destruction is not a few-days thing.
