Power grids tend to fail just about everywhere that experiences extreme weather. Its not necessarily a US-only thing. Its just that the US experiences a pretty large share of extreme weather compared to most of the developed world. Far more tornadoes, hurricanes, wildfires, etc. affect the US than say, Europe.
California's rolling blackouts were not the result of any particularly extreme (for California!) weather. Similarly, hurricanes are not new to most of the hurricane-afflicted parts of the country. Wildfires have been a force in the US for a long time, and the West has experienced seasonal wildfires for decades.
The difference is the US doesn't generally build or maintain infrastructure in a fashion commensurate with the extant risks here (which are different than those of e.g. Germany). Obviously, it is possible to keep a grid running when it is extremely cold outside, see the Nordics and Russia, for example. The US just makes systematic choices not to build & maintain to that standard.
What kind of similar weather risks do the Nordic countries or Germany experience that would be an equivalent to the tornadoes, hurricanes, and wildfires the US experiences on a very regular basis? I truly don't know what kind of similar risks they face and would like to rectify my ignorance.
