correct me if I am wrong, page-35

I keep mentioning, that I cannot see Aust reaching a 43% reduction in emissions in just seven and half years.
There seems to be no consistent planning, no regulations, no organised funding, and no skills base. We have Federal, State and Municipal govts all pulling in different directions, and pushing their own agendas. Then we throw in the interst groups of landowners, indigenous owners, Greenies etc.

And Yep, the numbers are staggering.

Report reveals the staggering scale of Australia’s net-zero path

Australia’s north would be transformed by five or six “Tasmania-sized” solar arrays and huge hydrogen hubs, and draw several million additional people as an army of workers arrives to build and service a vast net-zero economy.

Those are among the key findings of a landmark forward-looking, multi-year modelling project led by experts at the universities of Melbourne, Queensland and Princeton in the US, which for the first time details the staggering scale of the nation’s decarbonisation pathway.

Delivering on that vision of a near-zero carbon economy that exports energy to the world will also require wind and solar energy capacity equivalent to 40 times that of today’s national electricity market.

And in a serious wake-up call for the Labor government, the work suggests meeting the 43 per cent cut in emissions due to be legislated next month by the Senate implies the country will require solar, wind and transmission equal to almost five national electricity markets.

Alongside the staggering numbers involved, the research raises serious questions about how the country will manage what are almost certain to be critical skills shortages, the need for more foreign workers and a push to secure sovereign supply chains.

The report’s authors warn of the need to engage and win the support of households, landowners and communities, as well as the farmers who will host many of the wind and solar farms, pipelines and carbon-absorbing plantations.

They note that Indigenous-controlled lands are among the most suitable for making green power from hydrogen.

“A large capital investment is required, but the cost of energy services need not increase as a share of our economy”.

Across most of the modelled versions of the future, capital investment to fund decarbonisation of Australia’s domestic needs will be at least 50 per cent greater than what would happen if the country remained on fossil fuels.

The total annual domestic energy system cost will balloon from just under $90 billion a year today to more than $150 billion a year by the late 2030s and stay at that level through the 2060s.

Export industry

This includes alternative worlds in which only renewables are allowed by 2050, and one scenario in which CCS is limited.

Expanding that to develop an energy export industry capable of offsetting current earnings from coal and gas – for instance, via green hydrogen – involves investment from $100 billion a year to $600 billion.

Supporting that growth will require between 1 million and 1.2 million workers, the great majority of whom will be across northern Australia, helping support several million more residents.
