Nationals leader David Littleproud says he wants to have an “honest” conversation about Australia’s energy transition. Well and good. But maybe Littleproud himself can help that process by not telling outright lies.

On Sunday, Littleproud did us all a favour by spelling out in detail the Nationals energy policy, just in case it wasn’t already obvious: Stop renewables and wait for nuclear.

It has been, he admitted, the party’s policy for at least the last decade, if not longer.

That’s not surprising, given that its the favoured policy and strategy of Big Oil, Big Gas, Big Coal, and the likes of Gina Rinehart to whom the Nationals appear completely beholden. And it wins support at all levels of the Nationals grass roots through a co-ordinated and quite extraordinary campaign of fear and misinformation.

Littleproud’s train crash of an interview on ABC’s Insiders program on Sunday – well, it might have been a train crash if he had been questioned by someone with the wit to hold his talking points up to scrutiny – highlight the tragedy of Australia’s and the world’s current climate policies.

All these policies are focused on net zero by 2050, or 2060 if you happen to be China. As many scientists fear, it’s a target that is used as a prompt by naysers and do-nothings – such as the Nationals and the fossil fuel industries – to put things off for another day.

It is another excuse for delay, delay, and yet more delay – even though the science tells us, quite clearly, and more emphatically given the summer in the northern hemisphere and tumbling heat records – that what matters most is how quickly we act now.

Littleproud is completely unfazed by the science. In fact, it is a stunning rejection of the science. He wants a “pause” to the roll out of wind and solar and transmission links and a stop to the “reckless pursuit” of the government’s 82 per cent renewables targets.

He suggests that wind and solar has its place, but that solar should be built on city rooftops, not on “prime agricultural” farmland, or in remnant forests. We should wait for nuclear, he says, because “we’ve got time” and net zero by 2050 is the government’s “only commitment.”

He wasn’t asked the obvious question about the Nationals acceptance of climate science, the need to act by 2030, the need to try and cap average global warming to 1.5°C, a target that would require net zero to be reached more than a decade earlier.

Littleproud appealed for “honest conversations”, and then said the federal government’s 83 per cent renewables target requires 28,000 kms of new transmission lines.

Let’s be absolutely clear, that is simply not true.

The Australian Energy Market Operator’s Integrated System Plan suggests that up to 10,000kms of new transmission will be needed over the next two decades under its “step change” scenario, which includes the 82 per cent renewable share that is now the federal government’s target.

That renewables target, by the way, is key to reaching Australia’s modest emissions reduction target of 43 per cent below 2005 levels – a year chosen because of its peak land clearing of remnant forests under the Liberal/National Coalition.

Granted, the preparation work for the transmission lines have been poorly handled, by transmission companies, governments and the likes of AEMO, but it should be noted that most of these transmission lines are considered necessary even in the “slow scenario”, where science is completely ignored and coal hangs around a lot longer.

Littleproud’s number of 28,000kms is only mentioned in the “hydrogen superpower” scenario that imagines huge arrays of wind and solar in remote areas that might need to be connected to the grid. It is of course, his sponsors’ worst nightmare – because it means the end of the fossil fuel industry as we know it.

Littleproud then goes on to mention the prospect of nuclear SMRs (small modular reactors), and even something called “micro reactors”, which are little more than an idea, and probably even further down the pipeline than the SMRs, which are themselves at least a decade away, and not likely to be cheap.

The Nationals leader reckons big industry users like smelters might like the idea of micro reactors because they are modular, and about 3-5MW and can be used to power their facilities, and bring down costs.

It’s a ridiculous suggestion. A smelter draws up to about 500MW of load, so it will need around 100 of these things that don’t exist, and as the former head of the US Nuclear Regulatory Commission wrote recently, only ideologues and ‘tech bros” think that nuclear can be cheap. And the Coalition.

The owners of Australia’s smelters, for the record, have already made their views clear. Rio Tinto, for instance, has said that its smelters only have a future beyond the end of the decade if they can convert their power supply to renewables by 2030.

If not, they will not be able to compete with the rest of the world, either on cost, or on emissions. And who is providing the biggest stumbling block to renewables? The Nationals and fossil fuel industry led campaign against wind, solar and transmission.

And therein lies the tragedy, the dishonesty, and the absurdity of the Nationals’ and the Coalition’s stance against green energy.

It will stuff industry in Australia, and the local economy, long before it stuffs the planet and the environment. But by then, they – and the Murdoch media which trumpet their positions, and the mainstream media that refuses to question it – will have found something else to whinge about.
