“””and having a gas stove is crucial too.”””
People with gas are fortunate, every prepper should have backpacking stoves, which I do, including passive stoves that burn twigs, but for the home and convenience my countertop prepper stove is this one “Gas One GS-3400P Propane or Butane Stove Dual Fuel Stove Portable Camping Stove” they also have a 15,000 btu version.

For backup, people with natural gas or propane should also try to purchase the appropriate free-standing heater that doesn’t require electricity and practice connecting it somewhere, like a tee off of the furnace gas line or a tee off of the kitchen stove gas line, or off the water heater gas line, or gas dryer line, wherever the best room for the family to gather around the heater if you were without electricity and your furnace or pellet stove.
Here is an example of such a heater. https://www.amazon.com/ProCom-Heating-Natural-Infrared-Heater/dp/B0BLF54R22/ref=sr_1_7?keywords=natural%2Bgas%2Broom%2Bheater&qid=1694958508&sr=8-7&th=1
I don’t know if it’s because of the “petroleum is evil” mindset but of late I’ve noticed a LOT of Coleman white gas stoves and lanterns on Craigslist etc… these are great, fuel efficient and I’ve always run them on straight unleaded. I obtained my 425 stove in ID for $20, and my two lanterns for $15 and $25. Been using them for about 5 years now.
Just picked up stove and lantern pair for $65 that I’m going to give as holiday gifts.
