Exterior: what energy savings are possible?
Some day-to-day tasks do not necessarily mean that you use drinking water:
outside: cleaning your car, watering your garden or / and your plants, cleaning your garden furniture, etc.
in your home: washing your floors, flushing your toilets, etc.
For all of these tasks, consider using rainwater. To recover it, equip yourself with a dedicated tank. This type of tank does not have a filtration system, we can find some from 40 $.
For outdoor lighting, you can install solar-powered spotlights, equipped with motion detectors. These spots cost on average 40 $. Once installed, they therefore cost you nothing in electricity.
