Annually the average household spends on running electrical appliances: 82 on washing and drying, 49 on lighting, 38 on refrigeration of food, a rather wasteful 95 on the wide-screen TV, 17 powering computers, wireless networks and charging phones and, not surprising for the British, 23 on boiling the kettle for all those endless cups of tea. If families were more attentive and for example did not leave unnecessary lights on then they could save a considerable sum of money. Just appliances left unnecessarily on standby are guesstimated to waste 25 a year per household. The typical family's electricity bill could be quite significantly cut if we learnt to use electricity more frugally and became a little more attentive in order to reduce the waste. A trial showed an average saving of 75 a year on electricity bills which should prove a big incentive for most families.
Question: You can infer that the average households annual electricity bill (net of taxes etc) is a little over 300 (the sum of all the individual items listed).
