How much can we save from changing our habits?

Simple things can add up to significant amounts of energy and hundreds of pounds saved. Try:

  • Switching things off when they're not is use
  • Closing curtains at night when the heating is on
  • Cooking with the lids on saucepans
  • Using a microwave rather than a cooker
  • Taking a shower rather than a bath

In many cases a knowledge of the amount of energy actually consumed by an appliance, particularly on standby, is all that may be needed to encourage you to switch things off.

Here is a typical selection of household equipment that tends to left on 24 hours a day but won't be harmed by switching off:

  • Wireless broadband router 13.5Watts= 118kWh/yr= £24/yr
  • Satellite/Cable TV box 40.0Watts= 350kWhr/yr=£70/yr
  • Mobile phone/laptop charger 15.0Watts= 131kWh/yr= £26/yr
  • 42inch Plasma TV 21.0Watts= 184 kWh/yr= £37/yr

(These are all based on standby or their lowest state of activity and assume 24hr a day in this state with electricity at 20p/kWh.)
