Every week we'll post another easy tip to help you be environmentally friendly.
Eco-Tip 15
Keep the fridge full, but not too full. Food retains cold better than air so a fridge full of food uses less energy than an empty one. There's a catch though: don't fill it up too much. There still has to be enough room for air to circulate. You really need to eyeball it and see if you can find that sweet spot where it's not empty but not totally packed. What if you don't have enough food to keep it full? Buy lots of water (preferably in jugs rather than bottles since they use less plastic per unit volume) and keep them in the fridge.
