The best way to run your home - for your wallet and for the climate -is to have all electric appliances and cars powered by clean electricity. It's about half the running costs of a fossil fuel home and it's how we'll have the biggest impact on climate this decade. We explain why below.

Gas and petrol home

Average running costs

$5,300 per year

$53,000 over 10 year lifetime of appliances

Energy emissions

9,550 kg CO2e per year

To add to this, the prices of fossil fuels have continued a rising trend for the last 30 years and are expected to rise even more in future. Electrification already wins, and the gap widens every year.

When thinking about your next appliances, think about the total cost of the fuels you will use to power those appliances during their lifetime, their true cost not just the upfront cost. The most savings come from efficient electric appliances using rooftop solar.

These are Australia's greenhouse gas emissions, the majority of them come from energy use - machines that burn fossil fuels, these machines are everything from power plants to cars and gas water heaters.

Australian emissions can be split into two major categories. Export emissions and Domestic emissions.

Export emissions are the emissions created for the products we send overseas to be used by other countries. Domestic emissions are the result of our daily lives in Australia. They are our direct responsibility and under our control.

Next slide

The largest portion of domestic emissions are our households, followed by our businesses. They both use similar machines.

Next slide

Almost all of these emissions come from energy, the machines in our daily lives. Petrol cars, gas heaters, gas water heaters, gas stoves, and the fossil fuel power plants supplying most of Australia's grid network electricity.

Next slide

The solution to these emissions is switching our fossil fuel machines to efficient electric versions and powering them with clean electricity, including rooftop solar.

Luckily in Australia we have access to the cheapest home energy available in the world, our rooftop solar. We are the sunburnt country after all.

Over its lifetime rooftop solar costs about 3 cents per kWh, cheaper than any other source of home energy.

Next slide

Australian rooftop solar is so cheap that even a magic power plant providing free energy wouldn’t beat it.

The cost of sending that energy over powerlines alone is more than the cost of the energy that comes from your roof.

Next slide

Another benefit of electric machines is that they are far more efficient than their fossil fuel counterparts. This comes down to simple thermodynamics, electric machines have less energy waste.

Next slide

With this combination of saving on energy costs with solar and reducing energy use by using electric machines, it turns out we can have the same comfort at a fraction of the running costs and no energy emissions.

Next slide

This results in a fantastic opportunity for Australia, to lead the world on climate while saving money for families and putting more jobs into our communities.

Next slide

The story gets even better into the future. For the last 30 years fossil fuel prices have risen roughly alongside the consumer price index. Following this trend into the future shows the savings continue to grow for electrified homes.

Next slide

Simultaneously, the prices of solar, batteries, and electric vehicles continue to drop with manufacturing cost curves, or economies of scale.

Next slide

At a community level, this means less oil imported from overseas, thousands of jobs in installation and maintenance for the next decade, and millions in energy savings for homes, a lot of which will be spent in the local economy improving the community even more. It's a story of community economic abundance, and a once in a lifetime opportunity for Australia.
