Many places the reliability of power is good enough that we're prepared to handle that by going to a hotel. It's been decades since I experienced more than a couple of minutes without power.

Meanwhile I've had gas boilers fail twice and had to resort to electric heaters while waiting for repairs.

I live in Canada.

Snow and ice storms are a reality that make self sufficiency highly desirable.

I grew up in Norway. Snow and storms were insufficient to give most people a reason to worry. Some homes will have a fireplace or wood fired stove as a last resort, but it's more and more rare. In rural areas having a fallback is slightly more common.

So I stand by what I said: Many places the power reliability is high enough. A long outage in Norway would be treated as a major national emergency.

Portable cassette gas stove is pretty common here in Japan. This is the best for emergency. https://www.amazon.co.jp/-/en/Iwatani-Cassette-feu-Master-Po...
