Energy efficiency and environment ideas:
- Rain water tanks - used 200 litre barrels
- Rain water tanks - used 1000 litre plastic wired framed tanks
- Rain water tanks - childrens swimming pool under the deck
- Rain water tanks - used waterbed bladder under the deck
- Add more grassy areas on suburban roads to absorb rain/storm water (reduces the peak flows into storm water systems)
- plant (more) fruit trees and nut trees on public land
