I was part of the 2021 Texas blackout. My house is all electric and I lost power for 5 days and had two water pipes burst. I was not prepared at all. One thing I never thought of was having plumbing supplies to make repairs (copper pipe, fittings). When I could finally drive the roads, the stores were cleaned out of supplies.
I'm much more prepared now but not even close to where I need to be. I now have a stock of copper pipe and fittings, camping stove, coffee pot, candles, canned goods, charcoal stove, etc. I recently installed a propane heater and bought a Bluetti and I'm working on a small 800w solar system. Hopefully, I'll have that done in December.
