With The Lodge flushed there is a possibility of post-Turnbullian sanity, with the first priority being to re-evaluate Australia’s commitment to the Paris Agreement. As a nation, we are pauperising ourselves in a cause demonstrably false and easily discerned as such.
National energy policy is failing to satisfy what has been described as the trilemma of objectives: meeting national commitments for emissions reduction under the Paris Agreement; providing affordable energy; and ensuring continuity of supply.
There is potential flexibility for adopting different technologies to provide affordability and continuity of supply, but governments are tightly constrained by the need for national emissions reduction.
Australia is further constrained by policy shackles of its own making. Legislation is in place that rules out the most obvious technology readily satisfying the policy trilemma: nuclear generation. The reluctance to consider nuclear is baffling considering that seventy percent of France’s electricity generation is from nuclear and the global nuclear increase from 2016 to 2017 was a not inconsequential 65 terawatt hours. That is, nuclear provided more than 10 percent of the global increase in electricity generation, the equivalent of 10 new Hazelwoods.
Not surprising, the government’s favoured option of renewable energy, in the forms of wind and solar, is saddled with the burden of intermittency; there is no generation when the wind does not blow and the sun does not shine. In addition, expansion of the renewable base requires considerable reallocation of public funds from other infrastructure and social needs (schools, hospitals, transport, etc.).
As each day passes it becomes clearer that the federal government is finding the competing objectives of the policy trilemma impossible to resolve. The costs of overcoming intermittency and the subsidies to promote wind and solar expansion are driving electricity prices for consumers through the proverbial roof. In addition, major industries that underpin our national prosperity are threatening to close or relocate overseas.
It is time to re-evaluate our national commitment to the Paris Agreement and its requirement for emissions reduction. As a nation, are we pauperising ourselves in a cause that is now demonstrably false?
The basis of the Paris Agreement is the hypothesis of dangerous anthropogenic global warming. Computer models of the climate system, which few scientists understand, are invoked to project global temperature rise as atmospheric carbon dioxide concentration increases. The most recent assessment from the UN’s Intergovernmental Panel on Climate Change (IPCC) is that global temperature is projected to rise between 1.5oC and 4.5oC for a doubling of carbon dioxide concentration.
