Here's a tip for your survival kit, from a builder:
Start stockpiling nails - all sizes, especially big galvanized ones. They are metal, which will always have value, they are great for structural applications.

Without power, you'd hurt your wrist and elbow driving them, that is if you have a screwdriver.
Just sayin'.
