> Energy-efficient refrigerators are available at ~1.1 kwH/day. This reduces the needed energy estimate by about half. There's a number of people experimenting with converting chest freezers to chest fridges using an external thermostat. Apparently, these can be extremely efficient - people are reporting 10-20% of your 1.1kwH/day number. Of course, the typical downsides of a chest freezer apply to a chest fridge - they're typically much more limited in size compared to their upright counterparts due to ergonomics, and the larger they are, the more difficult they are to fully utilize. But they're a lot better than no fridge at all.
