Australia could rapidly get most of the way to net zero emissions by using existing technology to electrify 'low-hanging fruit', according to some experts — and with minimal disruption for most people.
Dr Griffith estimates that would increase to about three-quarters of households.The other changes might be harder to spot: EVs in the garage instead of petrol cars, electric water heaters instead of gas ones, and perhaps a big household battery to store all that solar power.
"You have to electrify the water heater, electrify the space heating, and have some form of batteries in the house, as well as the vehicle batteries.Australia has the highest per capita installation of rooftop solar in the world.Outside the suburbs, there would be enormous solar and wind utility projects, many of them exporting energy to countries with less land and larger populations.Heavy industries would also need to switch from fossil fuels to electricity.
"The advantage that fossil fuels have is that they're cheap on day one. The problem is they cost you more money to run on day two," he said.'We can get to 80pc emissions reductions by 2035' If Australia was to match the US pledge to halve its emissions by 2030, which is broadly in line with pledges by the European Union and the United Kingdom, it would need to cut emissions to 300 metric tons by 2030.By last year, emissions had fallen to about 500Mt: to halve its emissions, Australia needs to cut another 200Mt.The easiest places to cut 200Mt are electricity, stationary energy, transport and fugitive emissions, according to Professor Blakers.
