1. Bicycles along with bicycle trailers
2. Build homes that have natural cooling abilities (I've been looking at house designs from tropical areas and the 1800 for ideas there)
3. Store food that don't require refridge/freezers.
4. Cook in solar ovens (cheap stryofoam cooler and a sheet of plexiglass works amazingly well here in Texas).
5. Root cellars
6. Water cisterns to collect rain off roofs rather than hualing water from nearby lakes/rivers/pools.
