Announced or unannounced rolling blackouts or sporadic electricity.
People ought to be thinking of water and how they’ll deal with excrement.
We had that here last summer during the drought. Announced "brown outs" they called them; to conserve energy b/c it was so hot. Plus the unannounced stuff. That was an eye opener.
Worse? Burn ban that lasted forever. Think about that... all the things you'd do with fire: cook, boil, heat, burn debris. Making a fire had always been part of our "plan". That was a real kicker... the never-ending-burn-ban. When it lifted, it looked like a Viking community... everybody burning. AND... the dump typically costs $35 for low boy & pick up truck full; during ban, low boy alone was $75! It was creepy as all get-out... planes & helicopters checking for "fires"; signs up all over the place, even in places way out in middle of nowhere BURN BAN NO FIRES listing all that fine stuff. It was just creepy. I know it was bad, but it still was just creepy.
I bought a big industrial fan for the latter. ;^)
