You don’t have to scrutinise the 200 pages of the instruction manual before choosing your appliance. EU legislation toughened up some years back and it established an energy consumption labelling scheme for large appliances that have to display the label in a clearly visible way. A, B and C items have the lowest consumption. D and E items have a medium consumption and F and G are associated with high energy consumption.
Some small electrical appliances do not have to display the label, but refrigerators, freezers, washing machines, dishwashers, driers, electric ovens and air conditioning units have to comply with Law. According to the IDAE (The Spanish Institute for Energy Diversification and Saving) the differences are particularly noticeable with refrigerators. Ovens are another clear example: A class E oven uses twice as much as a class A oven.
