Making comparisons

Pupils often become very interested when they learn that the money cost of having their TV or computer on is a lot less that for devices such as the cooker, immersion heater or electric fire. Now they can speak with authority when parents complain: No wonder the electricity bill is so huge with you having your computer and television on all the time! However excessive showering may give the parent even more justification for complaint.
