Air is hard to keep cold
so if your freezer is usually mostly nearly empty , like mine , fill ice cream tubs or tupperware with water, freeze it and your fridge will have less work to do and will cost less to run . Plus you get good big comedy ice cubes to offer guests .

Alternatively, stuff it with crumpled up newspaper

This is the first good idea I've seen on here,
but my freezer is invariably well stocked.

It's really not this simple.
While it's true that a 10% full freezer will use more energy, because the compressor turns on more often, it doesn't make any difference if it's 50 or 99% full. (I verified this after I bought my massive freezer, and slowly filled it)
Also, very, very importantly.
The value of goods in your freezer is almost always significantly more than the electricity used to freezer them!

If you save 3 pounds a year by reducing the energy consumption by 10%, but now can't fit 20 quids worth of half-price stuff you usually buy in it, you just lost 7 quid.
If this happens more than this over the year - fail!

I just liked the idea of hacking large blocks of ice apart, to cool drinks.
Good to hear that I'm already quids in.

I can't quite get my head around what you are saying there.
Surely you take out the giant ice cubes to make space for the food which you want to put in, as and when necessary?
Also, wouldn't you lose £17? Or have I firmly grasped the wrong end of the stick here?

I like this and I'm clicking it :)
Mainly because I love the thought of offering guests gigantic ice cubes with their drinks :D

I think you may be violating some law of thermodynamics here.
Firstly, if you do save any energy by having the ice in there keeping it cool, you lose that money by freezing it in tue first place.

Secondly, keeping a big block of ice cold uses more energy than not doing.

I think.

Yes , but big ice cubes = funny
see below.

I'm not sure of the science behind this...
...but the giant ice cube thing made me laugh, so it gets a click!
