"It uses less electricity than a modern frig"
So that seemed incredible; but after doing some research it is plausible (with caveats). I have a few questions:
1) What 'modern' fridge are you using for comparison? There is a substantial difference between 1982, 2002 and 2022.
2) What are the volumes of the two fridges being compared?
The average 1940s fridge looks to be only 6-8 cu ft; while the average 2000s fridge is 20+ cu ft. Even if it slightly beats the modern fridge on total electricity, it's probably only cooling 1/3 to 1/4 the volume
For example in the 1940s you might be around 400kWh; but if its 7cu ft, its only getting 57kWh/cu ft/year; and comparing it to a 550kWh fridge from 2002 cooling 21 cu ft for 26kWh/cu ft/year. (And that's a 20 year old not particularly efficient "modern" fridge... you could get that down to 300kWh annually on a new fridge if you buy specifically for efficiency)
Sure the 1940s fridge might beat that not particularly modern or efficient "modern fridge" on total use but it's still not really a win unless you only need 7 cu ft. And if all you need is 7 cu fit, in 2025 you can get 8 cu ft for 167kWh year. (60% less electricity)
