...When the temperature is lower than this, the fridge freezer will
use more energy to maintain the right temperature.

How can it take *more* energy to run a freezer if the ambient temperature is
lower and therefore there is less heat transfer from the room to the freezer
that the compressor needs to remove. Seems counter-intuitive. But then it
always seems counter-intuitive that a vacuum cleaner uses less power (and
the motor runs faster) when the outlet is blocked by your hand and the
hoover is sucking hardest. I can see why this is (lack of airflow), so maybe
there's a similar reason why a freezer in a cold room (more similar to the
temp inside the freezer) uses more power.
