Electricity and Gas Consumption Calculator
Now that you've used our Energy Consumption Tracker to estimate how much electricity you use, let's break down what your results mean—and how you can use this information to reduce your power bill. From kilowatt-hours to energy-saving tips, we’ll guide you through everything you need to know.
What Is Energy Consumption?
Energy consumption refers to the amount of electricity used in your home over time, usually measured in kilowatt-hours (kWh). One kilowatt-hour is the energy it takes to use 1,000 watts for one hour—for example, running a 1,000W heater for one hour.
Why Does Energy Consumption Matter?
Understanding your household energy consumption helps you:
- Compare energy providers and plans based on your actual usage
- Identify high-usage appliances and habits
- Find opportunities to save on your electricity bill
- Track trends over time, especially seasonal spikes
Average Electricity Usage in Australia
Your energy usage depends on a range of factors including household size, appliance use, and daily routines. Below is a general guide to average annual electricity usage by location and household size:
Average Annual Electricity Usage (kWh)
| Household Size | NSW | VIC | QLD | SA |
|---|---|---|---|---|
| 1 person | 2,000 – 3,000 | 1,800 – 2,800 | 2,200 – 3,200 | 2,000 – 3,000 |
| 2–3 people | 3,000 – 4,500 | 2,800 – 4,000 | 3,200 – 4,800 | 3,000 – 4,500 |
| 4+ people | 4,500 – 7,000 | 4,000 – 6,500 | 4,800 – 7,500 | 4,500 – 7,000 |

What Uses the Most Electricity at Home?
Some appliances and systems consume much more electricity than others. Knowing which ones are the most power-hungry can help you find opportunities to save.
Common high-usage appliances and systems include:
- Heating and cooling systems
- Water heaters
- Refrigerators and freezers
- Clothes dryers and washing machines
- Electric ovens and cooktops
- Dishwashers
- Televisions, computers, and home office equipment
Tip: Look for energy-efficient appliances with high star ratings and use switchable power boards to turn off devices when not in use.
How to Save on Your Power Bill
Once you understand your energy usage, there are several simple ways to reduce your consumption and lower your electricity bills.
1. Compare Electricity Plans
One of the fastest ways to save is by switching to a better plan. Use our electricity comparison tool to compare providers based on your actual usage and postcode.
2. Use Off-Peak Power
If you’re on a time-of-use tariff, run major appliances like washing machines, dryers or dishwashers during off-peak hours. Learn more about peak and off-peak electricity times.
3. Improve Insulation and Draft Sealing
Up to 40% of your household energy use may go to heating and cooling. Proper insulation, window coverings, and sealing drafts can help maintain indoor temperature more efficiently.
4. Consider Solar Power
If you're a homeowner, installing solar panels can significantly reduce your reliance on grid electricity. Explore options in our solar energy guide.
5. Track Your Usage Regularly
Use this tracker whenever your household situation changes—like adding a new appliance or shifting your work-from-home routine—to stay on top of your energy consumption.
