Thanks for that.

This is extremely surprising, no. Motor/compressor/refrigerant/insulation design have all improved considerably.

Any insight there?

Usage patterns clearly have an impact, but I doubt they change much for a particular family across models -- some models have little doors for heavy use items to reduce air exchange, compartments probably make a big difference ('glass' shelves instead of wire).

Interesting. /beardStroke

Apart from improved insulation I don't think there's been much in the way of improvements since the late 30s --- if you look at the hermetic systems, they haven't changed much in decades.

In fact, the newer "environmentally friendly" refrigerants are less efficient than CFCs... so it's sort of a tradeoff between risking more ozone depletion when they leak, or putting more CO2 into the atmosphere from the higher power consumption...
