Staying cool and comfortable during the hot summer months doesn't need to be expensive

Here are some simple ways to keep cool whilst saving energy at home.

  • Cool the rooms you use most frequently and keep the temperature between 23 and 26 degrees. You’ll be comfortable and save money on your energy bill too.
  • If you are enjoying the benefits of rooftop solar PV, consider pre-cooling your home and using your washing machine and dishwasher when the sun shines.
  • Use a cold-water cycle when you do the washing. This can save you about $115 a year.
  • Avoid using appliances like your dishwasher between 4 pm and 7 pm. This can save you up to $100 a year.
  • Turn non-essential appliances off at the power point – up to 10% of your electricity could be used by gadgets and appliances that are on standby.
  • Set the temperature of your fridge to between 3- 5 degrees and the freezer to -15 degrees.

If you’re on a flexible pricing plan, using appliances in off-peak times could save you over $100 a year. If you're at work all day, switching your electricity to a flexible pricing plan could make sense because you already use most of your energy in peak or off-peak periods. Compare energy plans and save.
