You should always have enough supplies for a short term emergency. That’s not doomsday prepping, it’s just common sense.

I’m not a prepper IMO, but I have rooftop solar with battery backup, a few smaller portable batteries and UPSes on my critical stuff, and some oil filled radiators since my heat pump isn’t connected to the solar setup.

At any given time we generally have a month or more worth of food in the house in frozen and dry/canned goods. Also, several gallons of bottled water.

I also keep some stuff under the back bed of my car’s hatch, first aid kit and emergency blanket, and battery jumper kit as well as a battery powered tire inflator.

I live in a semi-rural area, and in an emergency, getting out and/or getting food and necessities may not be possible. And if there’s a wildfire I may need to evacuate fast, so important to have what’s needed. This sort of thing is like… If you have the means, why wouldn’t you?
