Build for resilience

What still works when the grid, the mains or the weekly delivery does not. These are chosen for what they do on the bad day, not the average one.

Rainwater harvesting and storage: Collects roof runoff; simple and low-tech, but supply varies with rainfall and needs treatment before drinking. Roof surface accumulates dust, pollen, and bird — Why this one: A supply that does not depend on anyone else’s pumps.
Rocket stove cooker: Small-batch, high-efficiency wood-fuelled cooking stove; sized for cooking rather than space heating, distinct from a rocket mass heater. — Why this one: Cooks without electricity and burns what you can gather.
Insulated operable shutters: Removable or foldable insulated panels over glazing at night, cutting heat loss when the sun isn't providing gain anyway. — Why this one: Holds heat in through a cold night with nothing running.
Composting toilet (dry): Also called a dry toilet: no water use at all (a scoop of sawdust or similar carbon material after each use instead of a flush), so it produces no blackwater st — Why this one: Keeps working when the water is off, which a flush toilet does not.

This is a short list, not the whole catalogue

These are a handful of picks to get started. The full set of options for every need is in the catalogue, compared on the same axes and filterable.
