My refrigerator choices are:
my unreliable RV fridge currently running on propane
or my mini-fridge with it's non-freezing mini-freezer
or my old non-frost-free fridge in my mobile home.
Then I ran across this article Life Without A Fridge from Path To Freedom. Basically, they live in Southern California and don't own a refrigerator. I used to live in So. Cal. so I know the weather is a bit milder than here in Arizona. They also live within walking distance of a grocery store and pick up food daily. I suppose I could go to the store everyday and only buy enough for one meal. Perhaps I could utilize canned food more. I think the cost of electricity is cheaper than the cost of daily groceries. I can just imagine what I would buy if I went to the store everyday. I'd probably buy those pre-cooked meals from the deli. Plus, buying meals everyday would mean a lot of extra packaging and trash for me. I don't have one of those environmentally friendly stores on my side of town.
So, I'll stick with refrigeration for now. Maybe one day when I can scooter to the farmer's market or grow my own food I'll pull the plug and live without, but until then I'll enjoy my ice cream.
