How Much Power is Needed to Run an Average Home?

Posted in:


Modern homes use far more electrical appliances than ever before, and as a result, much more power is required to be able to run the average home. Advancements in insulation and modern technology have gone a long way towards making the absolute most of our power usage, but there are still several actions we can take to reduce our energy consumption further.

Here we take a look at how much energy is required to run an average home, as well as some of the ways to minimise the amount you are using.

Obviously, the amount of power it takes to run a home will vary considerably based on the way you live and the amount of electrical appliances, temperature control and so on, that you use on a regular basis. It could also depend upon:

  • how big your residence is
  • the number of people living there
  • the type and number of appliances
  • when and how appliances are used
  • whether you have a pool, spa, air conditioner or other energy-hungry devices
  • the climate you live in (and therefore whether you need to use more heating than other places)

Common appliance power usage

It’s relatively easy to figure out how much electricity your appliances use if you know their wattage. The wattage is usually printed on the appliance or its packaging, and is followed by a ‘W’ for watts or ‘kW’ for kilowatts. This will tell you how much electricity the appliance will use for each hour that it is running. Here are some examples to help you get an idea of the amount of energy popular electrical items use.


According to the Department of Industry, Innovation and Science, 252,356 GWh of electricity was consumed across Australia in 2014/15 (see table L).

While the volumes may vary considerably, on average Australians use 38 per cent of their home energy on heating and cooling, 25 per cent on water heating, 16 per cent on electronics and appliances, 7 per cent on fridges and freezers, 7 per cent on lighting, 4 per cent on cooking and 3 per cent on stand-by power.

Electricity saving tips


Considering that humans lived for thousands of years without electricity and survived just fine, it is incredible to see how addicted to electricity people have become. Most of us feel lost in a blackout.

But electricity isn’t magic, and it requires a lot of natural resources to make it work. So conserving energy is not only good for your power bills, it will help reduce the carbon emissions that we are releasing into the atmosphere.

There are plenty of easy ways to be responsible with your power usage and conserve energy in your home.
Here are a few of the things you can do to reduce your home’s power usage:

  • Wash your clothes in cold water
  • Set your computer to automatically switch to ‘sleep’ mode when not in use
  • Make better use of natural light
  • Watch less television
  • Take shorter showers
  • Re-insulate your home
  • Minimise your air-conditioning use
  • Switch appliances off at the wall when they aren’t in use
  • Use a lamp instead of a main light when you only need a small amount of light
  • Use energy-saving bulbs, like compact fluorescent globes
  • Always turn off lights in rooms you aren’t using
  • Use an electric kettle to boil water rather than the stove
  • Only run the dishwasher when it’s full, and use the economy cycle where possible
  • Dry clothes naturally rather than in the dryer where possible
  • Dress appropriately for the seasons, rather than immediately turning to air conditioners or heaters
  • Insulate your roof
  • Set your fridge to 4 or 5 degrees and between your freezer to between -15 and -18 degrees
