Where you live has a serious impact on your energy bills, with some states and climates having far lower power usage each year than others.

We've gone through all the data in the AER's 2020 Residential Energy Consumption Benchmarks report to give you an idea of how your consumption stacks up against others, and where you could move to lower it.

  • Keep in mind.The AER report is updated every 3 years and the next one comes out in December 2023.

Consumption varies significantly by state. Tasmanians use the most per year, 8,619kWh on average, especially on heating in the cold winter.

Victorians use almost half as much power annually as Tasmanians and have the lowest consumption at 4,615kWh.

Larger households consume more energy, but just how much depends on the capital city and what climate it's located in. Residents of Hobart used the most power for each household member on average, while Melbourne residents used the least.

The amount of energy households consume can depend on where you live, with some suburbs having more than twice the average power consumption than others. The average household size for each suburb is taken from the 2016 Census, while power use is taken from statistics published by New South Wales distributor Ausgrid.

Here's an idea of how much energy 5 common appliances in your house might use every day, and over the course of a year.

Australia is a huge continent with extremely diverse climates. The climate you live in affects your heating and cooling bills.

Warm, temperate areas like Sydney have low annual consumption (average of 5,154kWh), while cold areas like Hobart have very high consumption (7,229kWh average).

Climate zone DescriptionExamples
1 High humidity summer, warm winter Cairns, Townsville
2 Warm humid summer, mild winter Rockhampton, Brisbane, Coffs Harbour
3 Hot dry summer, warm winter Mt Isa, Western Downs, Longreach
4 Hot dry summer, cool winter Dubbo, Whyalla, Mildura
5 Warm temperate Urban Sydney, urban Adelaide
6 Mild temperate Urban Melbourne, Adelaide Hills, Ulladulla
7 Cool temperate Canberra, Hobart, Yarra Ranges
8 Alpine Small sections of alpine Tasmania, and the Snowy Mountains

Once again, the effect of solar on your power consumption depends largely on the climate you inhabit. Warm, temperate regions like Sydney or Adelaide saved the smallest amount of power with solar, while areas with hot dry summers and cool winters saved the most.

Climate zoneExample towns/regionsAnnual gap in power consumption between solar and no solar (kWh)
High humidity summer, warm winter Cairns, Townsville 344
Warm humid summer, mild winter Rockhampton, Brisbane, Coffs Harbour 392

    How many kW of energy does a house use per day?

    If the median watt-hours of a home per day is 30,000, to find out how many kilowatts it takes to run a house using direct calculations, simply divide the wattage by 1000 to get 30. That means that the average kW used in U.S. households is 30kW per day, which averages at around 900kW per month.

    How many kWh does an average house use per day UK?

    What is the average electricity usage per day in the UK? The average UK household will use between 8.5kWh and 10 kWh of energy. This is only a guideline figure as there are many influencing factors that affect this figure.

    How many kW is a normal house?

    In 2021, the average annual electricity consumption for a U.S. residential utility customer was 10,632 kilowatthours (kWh), an average of about 886 kWh per month.
