This goes to how quickly it can be done:

Thats a great article and how I would envisage the future too. I've repeatedly said on here, how I'm a massive advocate for rooftop solar and I think heat pumps are massively underused. With the amount of sun we get, we are one of the best places in the world to use heatpumps as the ground in Australia retains a lot of heat.
The government should be immediately updating the required environmental level for all new homes. We should now not be building homes that do not allow for a significant reduction in expected emissions. The state government already provides guidelines for a zero carbon home, but IMO this should be legislated, rather than up to the individual and the builder. Its entirely achievable and would probably increase the cost of a house by around $15-20k but subsidies on new builds can help with this.
A zero net carbon home combines an energy-efficient building design and fixed appliances with a solar energy system to help reduce running costs, increase comfort, and curb carbon emissions.

IMO homes are relatively easy to fix, industrial buildings will be the ones the government really needs to focus on. A lot have moved to LED lighting but I think there needs to be a very large switch in direction to try and push businesses to install rooftop solar.
The first stage in our energy transition, has to start with a reduction in consumption from the grid, whether that be the electric grid or related to gas consumption (heat pumps are the big game changer here).
