Tip #16: Filling the gaps
Budget: $0
Time required: few minutes
Estimated Impact: Energy savings
Tip: Because solid items hold cold better then empty space/air your fridge or freezer needs more energy to keep all the contents nice and cold, whenever it gets low on contents.
Consider filling up some op this space with some water filled containers you may have lying around (like in your plastic recycling bin…).
This way you’re reusing the bottles that you where going to recycle and your helping your fridge to stay cool with less energy.
