Energy Consumption

Calculating your energy consumption arms you with the knowledge to control your energy usage and costs, and allows you to identify areas of high energy consumption. Using the right tools you can then manage your household’s energy costs and usage to make the right choices for your household.

In 2014, the average household electricity usage in Australia was 5,817 kWh per year. With most people around Australia paying between 16-30c per kWh – reducing your household energy consumption could slash your electricity bill by hundreds of dollars each year.

So how can you calculate your energy consumption?

  1. Home Energy Audit

Consider doing a Home Energy Audit.  There are free audit kits in most capital cities that you can borrow from your local library.

A home energy toolkit has tools and helpful information so you can do it yourself. Find out how energy is being used in your home to better control your usage and make savings on your power bill.

You can use the guide/manual to explore your energy usage in more detail. You can measure your appliances’ energy use, running costs and even their greenhouse emissions.

Most home energy toolkits contain:

  1. Appliance meter
    • Measures appliance energy use, stand-by power, cost and greenhouse gas emissions.
  2. Infrared thermometer
    • Measure the temperature of your hot water and pinpoint hot and cold spots in a room.
  3. Spirit thermometer
    • Measure room and fridge and freezer temperatures.
  4. Compass
    • Identify which direction your home faces to make the most of free heating from the sun.
  5. Stopwatch
    • Used to calculate the water flow rate from your showers and taps.
  6. Guide
    • Information, pictures and diagrams to help you carry out your audit.

  1. Compare your consumption

Calculate how much electricity you use compared to other similar households in your area using this simple tool.

Compare what the average electricity consumption is in your area with the consumption listed on your electricity bill to see how your household compares. However, this is just a rough estimate.

  1. Manual calculations using your meter

You can do manual calculations using your meter and previous electricity bills to work out your energy consumption. Your electricity meter reading shows you the total amount of electricity used over the life of your meter.

You can determine how much electricity has been used over a period of time by subtracting a previous meter reading from your current meter reading.

Electricity meters measure your energy use in kWh, which is the same as your bill.

  • [ the difference between readings] = kWh of electricity used.

Multiplying the amount of electricity used in your home by the tariff on your bill will give you an indication of your energy costs.

  • [difference between readings] x [tariff on your bill ] = kWh of electricity used

Use regular meter readings daily or weekly to keep track of how much energy you are using to see the impact of the changes you are making.

A simple way to record your readings is with an electricity meter diary which can reflect any changes you do to your energy consumption over time.

You can use our example below to create your own.

You can also estimate the running costs of current appliances or compare new appliances to make an informed purchase. Did you know appliances contribute up to 40 per cent of your electricity bill?

Look for energy efficiency ratings when upgrading your appliances – the more stars the better!  The energy rating label will arm you with all the information you need to help you choose a more energy efficient appliance.

Knowing how much energy your household consumes and when, can result in some serious savings on your electricity bill.

If you are one of the more than 1.64 million Australian households with solar panels on your roof, you can reduce your energy consumption by using your most energy draining appliances such as the dishwasher or washing machine when your panels are producing more energy than your household is consuming.

If you don’t have panels, you can monitor your electricity consumption and reduce your electricity bill by using your energy draining appliances at times when electricity prices are lowest. Some electricity plans charge different prices at different times throughout the day for using energy. By timing your appliances to come on when energy is cheapest you can save big on your electricity bill.

With smart energy monitoring like Reposit First , you can monitor your household’s energy usage in real-time, and even get predictions for your household energy usage. Letting you manage and plan the best times to use energy and still reduce your electricity bills.
