My refrigerator died a while back and I have chosen not to replace it. It used a lot of electricity and I think I can see a savings every month in my electric bill.
People did just fine without a refrigerator in the 1800s and earlier. People who do not bicycle travels do not carry a refrigerator with them. People who walk the Appalachian Trail do not stash a refrigerator in their backpack. It should be possible for me to get by without one.
Generally this work. I need to shop more frequently. In the summer fruit and vegetables only last 24 to 36 hours when it gets over 90F in my apartment. Thus, I am happy we finally have fall weather. Some days are still in the 70F range, but fruit and vegetables typically last about 3 days in that range. And once it gets even cooler, I plan to keep my thermostat set in the low 60F range. Some fruit and some vegetables will last up to 5 days in that range.
I really do not need all the accessories of the 20th Century. Afterall, this is the 21st Century, and now is the time to adapt to our future.
