GREAT question!
well, since the last year i have a FRIDGE again! i was in the local shop ((in india) and saw they had some new looking 5**** enefgy efficient ones.. i spun it round as i always do, and checked the power use.. It said it only used the equivalent of 50 Watts!! its a proper fridge /freezer.. and my mind was blown!

its works on a new digital compression pump that can work at a lower speed, it is virtually totally silent and i checked it with a clamp meter as soon as i got it, and it was showing 48Watts.. I also turn it off at 10pm and on again at 8m, .. so it hardly draws much power.. in fact i dont even notice it most of the year as my batteries are running at 100% most of the day, and i go to bed nice n early.
