Three main questions you should ask yourself.
1. Do I know how to make basic bread and cheese?
Making Bread
Just need a hand crank printing press and ink. Now making paper ………
Seriously, cooking skills are not difficult, but it would take most people a lot of trial and error to cook from real ‘scratch’. I grew up on a farm in a large family, so we learned cooking, canning and gardening.
2. Do I know how to hook up a generator to a house without killing myself?
Generator
Useless with active EMP pulsing, But for basic survival modeI have not wired one to a house circuit. However I have rewired a few houses, so if I was going to wire a small generator to a house circuit I would either
1) disconnect the wires from the circuit breaker and splice it into the generator
2) or use a simple extension cord for a few items.
And I would never run one inside a house. Most portable generators are small, so I would limit their use to essential items in this order: Fridge, Freezer, Water Pump. Wiring a large permanent generator to a house circuit is bigger undertaking ….. it is good to have a few electrician friends.
3. So the world has come to an end and 99% of the population has vanished, what do I do about the people who can’t help themselves?
Saving all; Hmmm …. When in survival mode, you try to survive. If you are traveling to a destination, you make do with what have. Do not swallow the Kool-Aid or the Blue Gullible Pill.
If you decide to remain/settle in an area, then you have a need to work with your neighbors, as few or many as there are. If you are trying to save the world, remember that people locked in areas have a matter of 1 week to survive without water. Maybe public water would last a little while, but maybe not. So any hospitals, prisons, or wards that are not checked/emptied in one week might only have bodies to bury.

Not sure of the post before that said beer lasts for years in cold storage root cellar (54F), maybe Butwiper or the Beast would, but not homemade beer. No chemical preservatives for the brew.
One of the more important items to own is yeast, as it is the building block of bread, cheese, and beer. You can preserve it by keeping a small clump of moist sourdough as starter.
Written Sources of how to survive without electricity are many, and may be found in most libraries. Books on camping, survival, old farming, gardening, Home remedies, raw medicine/herbs, wildlife, and hunting are still plentiful, as people still look whist-fully on the good ole days
Owning those books might be pretty valuable.
A few examples of books still in print:
Back to Eden by Jethro Kloss
Tillers International sells books and gives classes
