The CSIRO Low Emissions Technology Roadmap report has been released by the Australian Coalition government, purporting to show that the cheapest avenue to cutting emissions is by limiting wind and solar and focusing more heavily on gas-fired generation.
But in reality, it shows no such thing. Or at least, it shouldn’t.
The report relies heavily on different scenarios. Extraordinarily, the primary scenario that focuses on high amounts of gas-fired generation and limits to wind and solar is paired with high gains in energy efficiency and energy productivity across buildings, transport and industrial processes.
But the scenario for high wind and solar assumes business as usual on efficiency and productivity, meaning that the wind and solar scenario assumes 50 per cent more electricity generation is required in 2050 than in the scenarios where the amount of wind and solar is capped, or higher levels of fossil fuel generation is assumed.
Little wonder, then, that the high …
