Engineers get pretty excited about energy efficiency because it not only saves money and precious resources βitβs better for the environment too.
Machines can be tested to see how energy efficient they are.Β If youβve got a new washing machine or fridge freezer or been in the sort of shop that sells them you might have seen coloured stickers on the front which shows their energy efficiency rating with A, A+ or even A++ being the best, and G the worst.
Why not have a look and see if your washing machine or fridge has an energy efficiency rating?
