In addition to bringing reduced emissions of supposed planetary warming CO2, government plans for wind and solar to dominate electricity supply assumed these technologies would become cheaper than the coal and gas they were to replace. Wind and solar were to be nurtured by government support, transforming them from ‘infant’ industries into mature supplies. But the level of subsidy, far from falling, has increased as they matured.

Moreover, the shadow price for CO2 that the
Australian Energy Regulator (AER) regards as necessary to achieve the government’s Net Zero ambitions rises over the years to 2050 to $420 per tonne. This equates to a tax of about $200 per MWh for gas and as much as $400 per MWh for coal on top of their underlying costs of $60-80 per MWh.
Because that shadow CO2 price is incorporated as a cost in energy supplies, its level in 2050 means a tenfold increase ($500 per GWh) on the wholesale electricity price that prevailed in 2015 (the year before renewable energy subsidies forced coal generator closures thereby creating a ‘new normal’ of doubled wholesale electricity prices). Here are the wholesale prices over the past 20 years.

The introduction of subsidies for wind and solar energy started small with former Liberal Prime Minister John Howard introducing a requirement that ‘2 per cent of additional’ electricity must be comprised of wind or solar. That was quantified under the 2001 Mandatory Renewable Energy Target as 9,500 GWh, which was actually over 4 per cent of the total projected electricity supply.
This has steadily been increased – the 2013 Abbott government was the only one that sought to reduce it – an attempt that led to his successor assembling energy subsidy-seeker forces to overthrow Abbott. Some 30 per cent of electricity supply (73,000 GWh) now comes from wind and solar with the government planning for this to become 82 per cent by 2030.
Neither the government, nor any of its agencies, provide quantified assessments of the cost of subsidies provided to renewable energy. Indeed, suspicions that the government wishes to hide the full costs of its policy are heightened by its refusal to publish the prices it pays for wind/solar electricity contracts under its new signature program, the $68 billion Capacity Investment Scheme.
With the proliferation of different measures housed within many different departments – state as well as Commonwealth – calculating the effects has become increasingly complex. However, since 2006, I have published six estimates (2006, 2012, 2016, 2019, 2020, and 2024) that quantify the annualised cost of the subsidies prevailing in each of those individual years. Starting at $400 million ($660 million in 2023 dollars) in 2006, annualised subsidies have risen to $16 billion ($15.5 billion in 2023 dollars) by 2024. The 2024 estimates’ make-up is:

The attached chart shows all years’ subsidies (with years between those with specific estimates interpolated) and accumulated in 2023 dollars. By 2024 the total comes to $132 billion in 2023 dollars.

Not only have these subsidies had a wealth-depleting effect in and of themselves, but their outcome in forcing the replacement of low-cost coal by renewables has been national ‘econocide’, an early indicator of which is the declining levels of per capita GDP seen over the past few years. Australian electricity prices, having been among the lowest in the world only a decade ago are now at European levels and threefold those of China, Russia and India.
The energy-intensive production that had become the backbone of Australian industries, by definition, requires low-cost energy. Aluminium smelting is the acme of such activities. Having once gravitated to Australia due to our low-cost coal-generated electricity, it is now shifting to areas (China, the Middle East, perhaps the US) with low-cost gas and coal and a willingness to use these energy sources. Australian smelting businesses have been made uncompetitive by government energy policies and, now, being dependent on government subsidies, pretend to be seriously examining the government mirage of
low-cost firmed renewable electricity.
The basic costs of generating electricity in eastern Australia were last comprehensively and dispassionately estimated in 2017 in work for the Minerals Council by
Solstice. This put electricity costs (in today’s prices) at around $60 with coal and $80 with gas (if governments permitted its exploration and development). The coal costs are consistent with those experienced in
Vietnam and
Indonesia.
Even without Australia’s environmental lawfare and the CFMEU, the cheapest cost that nuclear power could be provided is about $80 per MWh. Renewables might be available at under $100 per MWh but firming them up – even if possible –and their additional transmission needs increases their costs three or fourfold.
Trump’s victory now makes it politically as well as economically impossible for the world to shift away from coal. In Australia, only the Nigel Faragist Libertarian-One Nation-Family First parties (plus a rationalist rump in the Coalition centered around Senators Antic and Canavan) are rejecting the subsidy-dependent renewables. Even though the Coalition in office will become more accommodating to coal, it may only be able to move gradually in view of its present caution and a likely Green/ALP prominence in the Senate.
While a nuclear-based electricity supply, as presently favoured by the Coalition, would avoid the ruinous energy policy being pursued by Labor, it would not provide the low costs that previously offered us competitive advantages. Nuclear is the best option for nations not having vast low-cost coal and gas but, tellingly, there are no aluminium or similar smelters planned anywhere in the world for nuclear-dominant electricity grids.
