We've got two big beer fridges in our hostel (well, one for soft drinks and the other for beer). Last month, the beer fridge packed up and so we had to leave it turned off for 3 weeks or so before the guy could come and fix it.
When the power bill finally arrived, I was shocked to see our bill had dropped by 10% - just with the beer fridge out of action. I'm now keen to investigate how to keep this bill down and so I'd like to hear whether anyone has had any success.
I'm thinking of buying a timer which turns off the fridges at about 11pm and turns them back on again at 11am the following day - some say that this won't actually save much energy as the fridge has to work 'hell for leather' to cool everything down again but it appears to me that the fridge is well enough insulated to keep the beers cold.
