Help your fridge be cool

Save energy on refrigeration by keeping your fridge at least half to three-quarters full: solid and liquid foodstuffs retain cold better than air does.

If you’re low on groceries, simply fill some icetrays, bottles or tupperware with water and use them as cold-keepers. 

You can pack the freezer compartment quite tightly, but don’t overstuff the cooling section; air still needs to circulate.

If you aren’t using the space optimally, and you regularly find you have just a few lonely items on the racks, consider swopping your fridge  for a smaller, less energy-hungry model.
