Store Food Without a Fridge
Most long-term food never needed a fridge. The fridge is for fresh food. The shelf is for food that was dried, sealed, or canned. If the power is out, you cook from the shelf. You do not try to save the lettuce.

The three conditions
Dry, dark, and cool. Moisture is the failure. A bag sealed damp grows mold. Heat in a garage ages rice faster than a closet. Light fades oil. A house cupboard beats a shed in summer.
While the power is out
Eat the fridge food first, on day one, if it is still cold. Then stop opening the door. The shelf is the rest of the week: rice, beans, oats, a can. Cook what you will finish. Leftovers do not sit out overnight.

Who this is not for
This is not a canning course and not a generator size. If the outage is also a heat problem, that is a different page.
