I’m up to tip number seven in my weekly series of how to save energy simply.  If you missed any then you can find all the tips here.

Today we’re going back to the fridge and freezer with tip number seven:

pack your freezer to save energy

Fill For Efficiency.

Is your freezer looking a little bit on the empty side?  Perhaps it’s a few days before you do a food shop and all you’ve got in there is a bag of frozen peas and a tub of indiscriminate contents (we’ve all been there!)?  Or maybe you never really have much food in your freezer to begin with.  Well, you could be pouring energy down the drain.

Freezers work best when they are full.  This is because freezers expend most energy when they have to cool down the warm air that gets in when you open the door to take food out.  A packed to the brim freezer means there is less room for warm air, and the frozen goods in the freezer cool down any wam air that does make it’s way in, meaning your freezer doesn’t have to work quite so hard.

So go wild and pack your freezer to the brim!  You don’t have to spend a fortune on food – plastic bottles filled with water will do the trick, as will freezer bags filled with ice cubes.  Styrofoam blocks will also do just the job.

A handy bonus is that if you have a power-cut it will take much longer for your food to defrost.

fridge tips to save energy

Fridges are slightly different beasts.  If you pack your fridge too tightly then you’ll over-work your fridge, using much more energy that you need to.  Your food will cool too much, and perhaps even freeze, and trust me, nobody wants frozen lettuce.  Other food might not cool enough, and nobody wants a tummy bug either.  Especially not frozen lettuce and a tummy bug at the same time!  So make so you don’t overpack your fridge and that air can circulate easily.

Again, you won’t save hundreds of pounds but if you change your habits and implement little energy saving steps here and there, like the ones that I’ve mentioned throughout this series (tips that don’t take too much effort), then these savings will soon add up, which is always a good thing!
