If you live in a big city, and you're planning to leave descendants without eating your neighbors, it might be a good idea to move elsewhere before a mega-Carrington event or micronova takes the grid down HARD.
No power means no internet, no lights, no pumped water, no computer controlled generators, inverters, no cars, no trucks. No re-supply of grocery stores. No way for any government to give orders farther than a shout can carry. Civilization collapses, all civilization, not just technological civilization.
Data is pointing to our sun, good ol' Sol, is a periodic micronova, with a periodicity of about 12,000 years.
