Live in Nordland on a island. Lost power for about two and a half minutes on Christmas day. I dont even think anyone but me noticed since it was still early.

Even when I was living in the snowier parts of America we didnt lose power. I would say losing power is not a universal truth in the slightest.

Same here, also on an island. We lost power for ~8 hours during a storm, however that is the longest I've ever experienced. I have this stone fireplace: https://www.norskkleber.no/ovner/marcello/ (Marcello 140), which kept my 75sqm living room heated through the whole thing.

Since that storm, we have decided to buy a second fireplace for upstairs with a cooking top.
