From a feature about low-tech refrigeration for rural Africa in The Ecologist I learn that “refrigerators and freezers account for 25% of the UK’s average household electricity bill” and that “US refrigerators use about 7% of all US electricity; that’s 25 large power plants’ worth”. Can these numbers possibly be right? They look to me like they might be the kind of mad extrapolation that gives the environmental movement a bad name.
