We have a water source that requires no electricity and do water reclamation.
We grow a lot of fruits, vegetables and nuts. Have about a year of MRE type food stores
Have a freezer stocked with beef, venison, pork and goat. Either I shot it, a family member raised it or it was locally sourced.
Keep some old survival books around and have a cell phone and laptop with all of wikipedia and some maps and survival guides in a faraday enclosure with a battery and solar array for charging.
Wife became a ham radio operator, which I thought was kinda dumb at first but it has turned out to very useful especially for storms
Keep a stock of medical supplies. Wife is in the medical industry so she's gonna have to be the nurse.
We don't do it because of the end of the world, although I do think society would devolve much quicker than most people think in an emergency even if it was only temporary, we want to be more self sufficient. To alfas point, I still order pizza and enjoy the luxuries of modern life but if someone turned the tap off tomorrow, I do have the means to be self sufficient just with a much narrower diet.
Most of the neighbors do similar things and we trade. I'm still getting my grapes going, so right now I trade with my neighbors for theirs, peaches, pears and pecans seem to be a big hit with them.
I have too many pears than I can use, so for this year's harvest I'm going to try and distill some of it. Maybe I can get some of my small gas engines to run on it, use it as an antiseptic, and maybe make some hooch.
Also have a family whiskey source.
Going to add honey production this year and chickens. Family all does chickens already.
My brother is experimenting with tilapia production
