I have a separate freezer/fridge and they amount to about the same as a standard European sized fridge (so no double door US style things) and the freezer uses about 63W when on and the fridge about 58W. I guess the compressors are of the same order but the freezer simply runs longer. Daily usage is about 0.9-0.92kWh. Less if you don't open them, more if you put something in the freezer/fridge which is not cold. I tried measuring if getting a new one would save power and was affordable somewhat cost effective but the short story is that the upfront cost could only be recuperated even by a tiny bit when kWh prices rise far into the 1 Euro/kWh.
