Speaking of power outages, we RARELY get them here in the north considering we can get all sorts of weird weather from regular snow, wet snow, or ice, sometimes all at the same time. We get the odd ones in summer from thunderstorms and such but I've seen some of the craziest winter storms and it never takes out the power. We did get a huge one that affected like 5k customers a few months back but it was because of a transport truck mishap. Whoops!
Then there's Quebec. Just a bit of snow (and they get a lot of snow) and the power is out everywhere. lol. I've done lot of OT because of that.

We monitor lot of equipment there so if power is out we get super busy dispatching techs with generators etc.
I really should invest in a power backup source though.... just because I've yet to see a big winter outage does not mean it will never happen. We had a planned one for 4 hours once, and it was getting pretty cold in the house. My servers were not quite enough to heat the house.

In a real emergency suppose I could shut down all the servers and power the furnace off the UPS. I don't think AC motors like square wave though.
