We are using 1000 kWh per year as a couple including hot water. With that we are very low in Germany, but even that is really without much optimization (though we lack some energy-intensive devices like a clothes dryer). Newer devices sold in the EU are relatively energy efficient. A typical fridge-freezer combo uses 150kWh.

>A typical fridge-freezer combo uses 150kWh. That would be a small <150L E class fridge, kept at 21C (with an air conditioner during the summer) Fridge efficiency has not increased much in the last decades (LG infamously had an efficient but horrendously unreliable 'linear compressor') - the only part that can increase efficiency is the time(s) it gets opened and how good seals the fridge has, and ambient temperature. Also smaller compressor by design cannot be super efficient. The newer devices part doesn't affect fridges all that much - vacuum cleaners have been limited, lightning requires LEDs (effectively) - which comes w/ its own issue of retrofitting, TVs (also relying on LEDs for backlight or OLED directly), power factor correction (for 75+W) and what not. Direct drive (brushless DC) and low temp washing for washing machines. Yet, there is no recent groundbreaking technology, it's just that the EU changed the efficiency labeling to prevent massive A+++ stuff.

  No, these are much larger fridges. https://www.otto.de/p/samsung-kuehl-gefrierkombination-bespoke-rl38a7b5bs9-203-cm-hoch-59-5-cm-breit-1400246809/#variationId=1400255051 https://www.otto.de/p/samsung-kuehl-gefrierkombination-bespo... 273l fridge plus 114l freezer, modeled power draw 134kWh.
