I should be more specific: an efficient 'USA-megahome-sized' fridge. Our typical fridge is often 25-35 cubic feet (850 litre)... that's about double the size of the small fridges used in many parts of the world.

That's not an average size even in the USA and you could probably still do it on less than 1 kWh.

Of course, once you're doing the 'USA-megahome-sized' thing, it's pointless to bother with energy efficient fridges. And many people don't!
