Saving Energy

We found these useful tips for saving energy at home on the Green Schools website.
1. Unplug electrical equipment – computers, mobile phone chargers – equipment on standby uses up to 20% the energy it would use when fully on.
2. Switch off lights & heating when you don’t need them.
3. Don’t overfill the kettle – only boil as much water as you need.
4. Turn your heating down to a comfortable 20ºC – lowering your thermostat by 1ºC will knock 10% off your heating bill.
5. Use compact fluorescent lamps (CFL’s) instead of traditional bulbs – they use 20% the energy and last up to 15 times as long.
6. If you have a short commute, walk or cycle instead of driving.

We also found out from the Green Schools website what you get for 1 kWh. Check out the interesting information below.

How we measure electricity
