How to be energy efficient-

Appliances use about a third of the average home's electricity bill. This amount is growing as we continue to buy more appliances and use them for more hours every day.
Appliances in our homes include:

• Fridges and freezers
• TVs, DVD players, stereo systems, gaming consoles
• Computers, printers and faxes
• Cooking equipment
• Washing machines and dryers.

When it's time to replace your old appliances choosing more efficient models is a good way to save on your appliance electricity bill. You can also save money by using your appliances sensibly and switching them off when you aren't using them.
