The nuclear renaissance dies, forgotten and bankrupt

Unless you were paying very close attention, you probably haven’t seen the news that construction of two Westinghouse AP-1000 nuclear reactors at the Virgil C. Summer plant in South Carolina has been abandoned, following the bankruptcy of Westinghouse earlier this year. There are two more AP-1000 reactors under construction at the Vogtle site in Georgia, which are also likely to be scrapped. Either way, this seems the right moment to mark the end of the nuclear renaissance which offered high hopes in the early 2000s. The biggest remaining carbon capture and storage project, the Kemper plant in the US, was also abandoned a month ago.

So, at this point, there is no alternative to the combination of renewables, storage and energy efficiency. This would be a good moment for those environmentalists who accepted and promoted the nuclear story to recognise that any further efforts in this direction can only harm the prospects for a low-carbon future.

More soon on this, I hope

Unscrambling the Toll Road Egg

That’s the title of a presentation I’ll be giving to a seminar run by the Institute for Sensible Transport in Sydney. Registrations are open until tomorrow (Tuesday 1 August) for those with a professional interest. For my readers, in general, here’s a link to the presentation. Please advise if the link works, or doesn’t, as it’s a newish feature in Dropbox I haven’t used much

Technology to the Rescue ?

There’s been a fair bit of buzz about an article in New York Magazine with an apocalyptic picture of climate change over the next century. I’ll for a more complete response later. But as it happens, I was already thinking about a much more optimistic post.

From the Climate Change Authority, of which I was a Member until recently, here’s a set of emissions trajectories consistent with a 67 per cent probability of limiting warming to 2 degrees.

There’s a pretty good case to be made that we are on the blue trajectory, and that, with decent political outcomes, we will be able to go below it and hold warming to the Paris aspirational target of 1.5 degrees. That would still have plenty of negative effects, for example on coral reefs, but it would not be an existential threat to humanity.

The points that are critical in the blue trajectory are a peak in emissions, right about now and a drop to zero net emissions by 2050. The first looks to have been achieved. As for the second, we are already seeing commitments to this goal from developed countries and jurisdictions, and there’s every reason to think it can be achieved at low cost.

As an economist, this is about the outcome I would have expected given a global commitment to an emissions trading scheme with a carbon price on a rising trajectory to $US100/tonne or so. In fact, we’ve seen nothing of the kind. There has been no real global co-ordination, and where carbon prices have been imposed, they have been low and limited in scope.

Instead, we’ve had a series of favorable technological surprises of which the most striking have been the plummeting cost of solar photovoltaics, and advances in battery technology allowing both low-cost electricity storage and affordable electric vehicles. There’s no reason to think these advances have run out, or that any of the remaining problem areas (air transport, cement manufacture and so on) will prove insuperable.

Less is more

Reading the news, I find a lot of items demonstrating a scale of values that makes no sense to me. Some are important in the grand scheme of things, some are less so, but perhaps more relevant to me. I think about writing posts but don’t find the time. So here are a few examples, which you are welcome to chew over.

* Blowing things and people up is seen as a demonstration of clarity and resolve (unless someone is doing it to us, in which case it’s correctly recognised as cowardly and evil). The most striking recent example (on “our” side) was the instant and near-universal approval of Trump’s bombing of an airfield in Syria, which had no effect at all on events there. In this case, there was some pushback, which is a sign of hope, I guess.

* The significance of art and artists is determined by the whims of billionaires. Referring to the sale of a painting by Jean-Michel Basquiat for over $100 million the New York Times says

most agree that the Basquiat sale has cemented his place in the revenue pantheon with Pablo Picasso and Francis Bacon; confirming that he is not some passing trend; and forcing major museums to acknowledge that, by not having the artist in their collections, they passed over a crucial figure in art history.

* As far as economic research is concerned, less is more. More precisely, an academic economist with a small number of publications in top-rated journals is better regarded by other economists than one with an equal (or even somewhat larger) number of ‘good journal’ publications along with more research published in less prestigious outlets. I can vouch for that, though it’s less of a problem in Australia than in less peripheral locations. I have the impression that the same is true in other fields, but would be interested in comments.

[fn1] To be fair, this is preceded by a brief acknowledgement that “auction prices don’t necessarily translate into intrinsic value”, but there’s no suggestion that any other measure of intrinsic value is worth considering.

Churchgoing Labor voters

What proportion of Australian voters regularly attend church and identify as Labor voters? How many of those are social conservatives in the mould of, say, Joe de Bruyn? If I’ve interpreted this piece by Crikey’s Pollbludger correctly, the answer to the first question is about 4 per cent. The relevant bits

This is partly reflected by the long-term decline in religious observance, with the proportion of respondents who attended services at least once a month falling from 23% in 1990 to 17% last year.

….

Of still greater interest is a pattern over the past decade in which the observant have grown more pronounced in their identification with the Coalition rather than Labor, with the gap reaching a new peak of 52% to 25% in the 2016 survey.

25 per cent of 17 per cent is 4.25 per cent.

Turning to the second question, I’d be surprised if socially progressive observant Christians (and members of other religious) didn’t account for 5 per cent of the total population of Australia. So, if Labor gets the support of half of those, that would leave less than 2 per cent of the population in the religious conservative Labor voting category. That’s comparable to the support for the HEMP (pro sex, pro marijuana) party in the last Senate election.

Drones (the good kind)

It’s now pretty clear that renewables can replace fossil fuels in their main uses, electricity generation and land transport, at a very modest cost or, as appears to be the case for electricity, with a cost saving. But that still leaves room for doubt over whether the economy can be fully decarbonized in time to hold CO2 concentrations to 450 ppm or below. Among the big gaps are air and sea transport.

I’ve tended to argue on the basis of the idea of induced innovation that, since there are plenty of possible options, at least one will work out, given some incentives to reduce CO2 emissions. That’s proved true for electricity (solar and PV worked, while other promising contenders like geothermal and Gen III nuclear haven’t), and more recently for storage. But it doesn’t seem to satisfy everyone.

So, I was struck to realize that drones (which I’ve always thought of either as toys or as particularly nasty weapons systems) may be on the way to displacing a good deal of air and sea freight transport in the relatively near future. Initially at least, the bigger ones are likely to use conventional engines, but with greatly reduced fuel costs, as with this proposal. But it’s easy to imagine a version that carries its own solar PV system being developed in the future – possibly slower but even cheaper than the current verison.

Moreover, the size and capacity of battery-driven electric drones is increasing all the time. The current leader appears to be the Griff 300, which can (as the name indicates) lift 300kg, including its own weight of about 65 kg. Apparently there is a Griff 800 either released or in the works. At least to my understanding, there’s no fundamental scaling limit here, although there will obviously be plenty of technical challenges. On the other hand, with batteries getting lighter every year, performance can be improved over time without any significant change in design.

None of this deals with passenger air travel which looms larger in the culture wars over energy policy that its objective significance as a source of emissions justifies. But again, in the absence of fundamental limits (the kind that apply, for example, to carbon capture and storage), a sufficiently strong incentive will in all probability bring forth a solution.

My submission to the government’s Climate Change Review

Submission’s to the government’s review of climate change policy close on Friday (so there’s still time to send one to climatechangereview@environment.gov.au, even if it’s just “Stop Adani”). It’s obvious to everyone now, including the government, that energy and climate policy are in a complete mess. So, there must be some chance of a radical change, possibly even one for the better. And there are plenty of options on the table.
I just put in a very short submission, which is below.

Submission
The terms of reference for this review refer to the government’s commitment to addressing climate change and to ensuring the adoption of effective policies.  However, these supposed commitments are contradicted by the government’s failure to respond, as legally required, to the Special Review of Australia’s Climate Goals and Policies, undertaken at the current government’s request by the Climate Change Authority.  
The final report of this Review was delivered to the government on 31 August 2016. Under the relevant legislation, the Minister was required to table the government’s response to the recommendations of the Review within six months, that is, by 28 February 2017. This requirement has been ignored.
I was a Member of the Authority until March 2017. I resigned when it became apparent that the government had no intention of responding to, or otherwise taking account of, the comprehensive Special Review in which I had taken part.
The absence of any response reflects the inability of the government to offer a coherent alternative to the policy toolkit recommended by the CCA. The current review should adopt the recommendations of the CCA Special Review, particularly including the introduction of an emissions intensity scheme for the electricity sector.
