2.1.1 What uses most energy in the home?
Most of us are aware of the need to be careful of how much energy we use in our homes.
Do you know which electric appliance would use the most energy if it was switched on for an hour?
Have a look at the power rating on some of your own appliances then see if you can put the list of domestic appliances in order. Put those using the most energy at the top by dragging the names up and down the list. The computer will tell you when you’ve got it right, and will offer you help after you’ve made a certain number of moves.
