What a waste!
Think about the house you live in and the ways in which you use energy at home.
In pairs, think of ten questions that you can ask others to find out how much energy is wasted. You can ask questions about:
- what electrical equipment is used at home
- the number and type of light bulbs in the house
- how often the heating is on
- whether the house is insulated
Electrical equipment left on standby or phone chargers left plugged in use up around £650 million worth of electricity – that's around £25 per household.
So switch it off! Other energy saving tips include only boiling enough water in the kettle as needed, and using energy saving light bulbs which can last up to 12 times longer than ordinary ones and use a quarter of the electricity. Turning our thermostats down by 1°C could save every household £40 per year!
