Saving Energy at Home

Light Bulb

There are many ways of keeping your costs down through energy efficiency measures.

For example:

  • Heavy or lined curtains are as effective as double glazing when drawn.
  • Blinds have no energy saving benefit.
  • Draw curtains at dusk to stop heat escaping.
  • Make sure the thermostat on the water cylinder is set at 60°C
  • Don't cover radiators with furniture or curtains or use to dry clothing.
  • Carpets and underlay have good thermal qualities.
  • Low energy bulbs produce four times the light for the same amount of electricity. This saves around £7 per bulb per year.

Using Appliances:

  • Digital radios are five times more inefficient when left on standby than analogue radios. Turn off at the switch or unplug.
  • Don't leave TV's on standby as they are using 85% of the energy of full use. DVD's and videos have similar problems.
  • Mobile phone chargers - Don't leave plugged in as they use 95% of the energy compared when actually charging
  • Low energy lighting lasts over six times longer and uses four times less electricity.

In the Kitchen:

  • Cover saucepans with lids whenever possible. Cuts condensation and reduces heating time.
  • Electric kettles are more energy efficient than a pan on a cooker.
  • Once vegetables are boiling turn them down to simmer and use just enough water to keep covered.
  • Electric toasters are more energy efficient than electric grills.
  • Slow cookers are more efficient for many dishes.
  • Use a jug kettle with a gauge or simply boil what you need. De-scale regularly.
  • Never overfill your fridge.
  • Keep your freezer at least three quarters full
  • Defrost your freezer regularly and never allow more than six mm thickness of ice to build up.
  • Whenever possible run dishwashers and washing machines with a full load, if you do only have a half load try to use the economy settings.
  • Wash at a cooler temperature such as 30ºC
  • If you are using a tumble dryer, wring clothes out first and do not over dry. Dry your washing outside when possible.
