DIY super efficient fridge.

[broodlinger]

Your biggest savings in a fridge is going to come from either a) insulating the outside, or b) insulating the inside.

And by inside, I mean that if you are opening the door to get a 16oz jar of sour cream, there's no reason to expose the entire contents of the fridge to ambient (i.e. summer) temperatures.

Supermarkets already know about this, that's why they have plastic flaps hanging from the ceiling.

Cost of plastic flaps?

just fyi I checked my fridge with my kill-a-watt. Ambient temps around 80 F and in 24 hrs it used 3.00 kwhrs. It's a whirlpool side by side style. I noticed it uses around 160 watts when the fan and pump are running but there was a time i noticed when the fan and pump where off and it was using over 400 watts for something (maybe frost control).
