I grew up in Siberia where it gets cold down to -40C (coincidentally it's also -40F). I don't recall power going out for more than a few seconds. 24h without power or heating sounds batshit crazy for me. If it's a regular occasion it means either the infrastructure is outright non-existent or it gets literally blown up like in Ukraine. Same goes for shoveling snow. Yeah, I did it. Probably about 5 times in 20 years.
