Castles and Cars — Cash Savings in the Suburbs

Rewiring Australia recently produced a report, Castles & Cars, with the support of Mike Cannon-Brookes who advocates for the electrification of everything in the Australian house. Not only heating, cooling and cooking, but also transportation. There are savings to be made in the suburbs if we electrify our castles and our cars.

One of the most exciting parts of the report for me was the fact that some of the assumptions have already changed. In Australia, petrol is up 30%, some electric cars (Tesla Model 3) are down 20% and electricity can be had at a much cheaper rate. Some state governments have already started encouraging the adoption of electric vehicles. TAFE colleges at the federal and state levels have begun planning training programs for the coming era of batteries and electrification.

This report reframes the debate on government support for home electrification from aid to investment in a better future. He postulates that an investment of $12 billion will generate savings of $302 billion by 2035.

Money saved by electrifying homes and transportation.

Australia’s 10 million homes are responsible for nearly half of the nation’s emissions, and nearly all of those emissions come from the way we use energy in cars and homes. With proper funding, electric appliances will incur lower annual expenses than fossil fuel powered appliances by 2024. I have a solar powered home with an EV and would say that is possible now.

“By 2030, Australian households could save more than $40 billion a year, which is close to – and could exceed in the future – our coal export earnings.

“The average Australian household currently uses just over 100kWh of energy, including the energy lost in thermoelectric power generation and the energy needed to power personal vehicles. If all users switch to electric solutions , this drops to just 37 kWh and can be almost completely satisfied with a solar installation with a capacity of 10 to 12 kW and a compatible battery.

The potential for solar generation on Australian rooftops is 245 TWh per year. The residential solar potential alone is 130 TWh, enough to power 10 million Australian homes with 37 kWh. “Cars are the largest contributor to household emissions and energy cost, accounting for 38% of household emissions and an average of about $3,000 per household in annual fuel expenditures.” It will only increase. As an EV driver, I watch gas prices constantly rise. I save $4,000 a year in fuel costs alone.

By replacing their current cars with electric vehicles, replacing their natural gas heating systems (water heating, space heating or cooking) with electric heat pumps and supplying their electricity from solar energy on the roof, the average Aussie could save significant amounts of money. .

“If this change is embraced now, and we replace current machines with zero-emission alternatives (from heaters to cars to power stations), we can win the global race to decarbonize and follow the trajectories of change. emissions corresponding to a 1.5 degree world.”

We must practice 100% clean replacement. If your gas stove no longer works, replace it with an electric one. If your water heater stops working, replace it with an electric or, better yet, solar one. When your car breaks down, replace it with an electric vehicle or possibly an electric bicycle coupled with public transport. We don’t need two cars in each garage. With a little planning, we could use a car and another form of transportation.

“Financing is clearly a piece of the puzzle that needs to be considered and thankfully the big banks are now offering consumer finance for these goods. The banks are not stupid. They know that by 2030 the household average Australian could save $5,000 to $6,000 a year on vehicle energy and fuel costs compared to 2021. …

“Providing rebates and financing to low-income households in this transition phase must be a national priority. …

“It’s not rocket science, we need to remove subsidies for gas appliances, stop expanding gas reticulation networks and phase out natural gas for new and existing households. New programs will be needed to develop markets for batteries and electric vehicles, with priority for low-income households. Australia will need to develop financing solutions for the lowest income households, including policies that incentivize both landlords and tenants to help distribute savings appropriately.

It is important to note that this is not only possible, but is now happening in the suburbs and streets near you. What we need to do is speed it up so that our castles and cars save us money, rather than cost the earth.
