Refrigerators are so efficient now, shrinking them does very little. The typical unit for sale in the US is ~$5/month to operate. Get solar and it's free. As for your opinions about meat, flexitarian is best really: eat whatever you want, just realize that you don't need to stuff a carcass into your neck 3x per day.

Yes, you're right--small fridges are often almost just as energy INefficient. My sis works at a green building supply store, so she gave me the truth on this one, after I was telling her that I thought I'd downsize too. She said it won't do any good :( But, perhaps it WOULD encourage us all to not waste food and to eat only what we need. That's cool

Compact fridges are notoriously inefficient. I've done the research on dorm fridges (one of the top energy users in student rooms) and it's not easy to find an Energy Star unit. I've found only one vendor and two models. So be careful, this is one place where size may not matter. However, the Energy Star rating does.

Compact fridges (under 6 cu.ft.) w/ the Energy Star label use about 300 kWh per year, average. Non-Energy-Star can use 400 kWh or more!

Once you get into full-size fridges, the energy use does have a stronger correlation w/ size so keeping it reasonable, like under 20 cu.ft., is important. But even fridges w/ Energy Star can vary 100% in energy use, so read the label and/or see

There are 100 models that use less than 1 kWh a day and many of these are easy to find in stores.

One more tip, it's also how you use it. Make sure the fridge has plenty of room for air to circulate around it, and don't locate them near heat sources if you can help it.

It seems to me the best thing about a small fridge is that it forces you to consider what refrigeratable things you are going to buy. In a Costco/Sam's Club society, you can't help but fill an enormous fridge and then be seduced into a gluttonous lifestyle, not to mention the pure hedonistic joy of the energy pig door icemaker. I think that I, personally, would save significant amounts of money, eat better and reduce my carbon footprint (not to mention expanding wardrobes) if I had a tiny fridge like Christine's energy efficiency be damned. Sadly, I'm too lazy and want to buy all my prepackaged crap in one enormous trip and let the chips fall where they may.
