> “Hundred year calm/clouds” need be prepared for Once you're preparing for events that rare, you have to first prepare for more common events, like failures in the power transmission infrastructure (the latest widespread one in my country, for instance, was only 11 years ago). And a lot of the preparation for these more common events (for instance, backup generators) would also help with these more rare events.
