What convenience? You open the door, a light goes on, it is cold or freezing cold inside depending on the door.
The end.
My parent's McClary fridge from the 1960s still runs on the original refrigerant.
Don't tell me about energy efficiency when
-
We are awash in renewable electricity
-
Building new fridges every five years filled with e-waste running garbage software requiring a networking infrastructure on top of it surely used a few joules as well.
-
It's not in a landfill.
I can't wait for the global energy crash, maybe we'll be calmer and wiser when gas is 100$/liter.
