 fridge energy usage

I was curious about the difference in energy usage between a mini-fridge and a full size fridge and did a quick look at some sizes. The smallest was the best but not by a very significant amount. I also looked at one of the largest (and expensive) that was "energy star" and it was significantly lower than the other large sizes. I did not compair brands, just sizes, so this is a very non-scientific list.
1.7 Cubit ft \$34/yr 318 kWh yearly usage
4.6 cu ft \$37/yr 342 kWh
14.8 cu ft \$47/yr 443kWh
18.2 cu ft \$51/yr 479 kWh
23.7 cu ft (Energy star) \$41/yr 388kWh
So I'll let the wife decide if I get a used full size or modify a mini.

Don't go by what is posted you can calculate what your cost will be with this simple formula: Volts x Amps = Watts. Watts x Hours run per day(2-4 is average depending on ambient temp) x Days per Year = Total Watts divided by 1000 = Kw x your cost per Kw on your electric bill. Mine works out like this; 115 x 5 =575 x 2=1150 x 365=419750 / 1000 = 419.75 x .06 = \$25.19 per year or .007 cents per day. This is a 20 cuft chest freezer.

6 cents a kilowatt hour?

Sounds almost mythical. We're over 14 cents here...

Cheers!
