We have above ground power lines in the nordics too. They are just built to handle our climate.

Where I live (pacific northwest), it's not snow that's the problem, but windstorms. Presumably knocking over trees, which in turn takes down power lines - which of course implies said trees are tall, in proximity to the power lines, and not cut down. I maybe average 24 hours of outage per year (frequently less, but occasionally spiking to a multi-day outage.)

I don't think that's something that can be solved with just "build quality"... but it presumably could be solved through "maintainence" (cutting down or trimming trees, although that requires identifying the problem, permissions, a willingness to have decreased tree coverage, etc.)

Yeah, it was interesting to see some above-ground-to-the-premises power delivery in some of the smaller Norwegian villages above the arctic circle. Things looked rather robust, though.

I lived in the Oklahoma and in Minnesota, and the difference there is already stark:

* OK suffered from plenty of storm-induced winter power outages (massive freezing rain cycles were common in my life). My mother's cotton bath robe, which she kept using until late in her life, had burn marks from when she reached for something over a lit candle during a power outage when I was four years old.

* MN suffers some, but people knew to develop meaningful contingency plans.

Both states have variegated buried-power-to-the-premises usage. It's not really to be expected as the norm in either place, but MN has far more than OK (funnily enough I grew up in a place in OK with it). Either way, the infrastructure robustness in North America looks like it arose from a dismal cost-benefit analysis versus a societal welfare consideration.

I left North America about 14 years ago for Europe. The difference is stark. We've only had one significant power interruption in that time (not even in winter); whereas stochastic neighborhood outages were commonplace in North America. What really freaks me out about the situation in North America is just the poor insulation of the structures and their low thermal mass. They will get cold fast.

Aside: A lot of friends and family in North America balked at the idea of getting a heat pump due to performance during a power outage: "when the power goes out, I can still run my gas." When I asked them whether the house was heated with forced air or used an electronic thermostatic switches, the snarky smile turned to a grimace.

When you live in a cold place, you learn to do things differently. You're naive if you don't pack warm blankets and water in your vehicle, for instance. You never know when you might find yourself stranded somewhere due to vehicular breakdown …
