Another related concept - have a chest freezer and cycle through frozen 2 or 3 litre soft drink bottles full of glycol that you put in a small/med well insulated cooler you use as a "day fridge". Most people keep way more than they should or need in a fridge, and often best to go straight to freezer to avoid wastage if you are not right on to eating leftovers. So this does not save energy because you don't run a fridge, you use extra in the freezer for the glycol bottles bthan if you just used it as a freezer, but your fridge is now small with a top lid instead of front doors, and you can heavily insulate a cooler very easily to make it super efficient.

Then there is milk, butter, veges etc that easily fit in 65l cooler for most families.
