2 weeks no power, no problem. Diesel generator sips fuel from a 500 gallon tank. Well pump does it's job, supplying with water. I'm on public sewer, but I'm on top of a mountain, so until the pipes fill up, it's not a problem for me, and it would be a problem for a lot of people before it was for me. Wood stove provides plenty of heat in the winter, with diesel as a backup. Wood stove doubles as a 2 burner stove for cooking, as well.
I suspect I could go for about 8-12 months before I started to worry about running out of meat. I grow most of my other food. I could go out with my remote hole puncher and get some deer if needed. I wouldn't have to go far, they're in my yard all the time. a 24cu ft freezer has easily a year's worth of food and that's on a battery that is charged by solar.
I'm remote enough that I don't have to worry about feral protesters. If I have to worry about roaming gangs, the cities are already burned to the ground.
