On broken promises and basic manners
Andrew Sooby writes: Re. “Crikey says: ‘no broken promises’ bites Tony on the arse” (yesterday). If you were to tell me that I’m politically naive, so be it. But I would still not be happy with your somewhat blase attitude to political promise-breaking and hypocrisy. I do not like promise breaking, or hypocrisy, especially from politicians. Who does? Why do they continue to make promises they cannot possibly be sure of keeping even a short time after making them? If they didn’t make ridiculous promises, then there would be no “good reasons” for breaking them. And while I’m about it, I could well have missed a Crikey censure on Abbott’s slobbish ill-manners turning his back on opposition speakers in question time. But in case you haven’t censured him, is that, too, just a “core part of political debate” that we’re supposed to brush off with a shrug?
Bishop is right about nuclear power
Dr Mark Duffett writes: Re. “Nuclear: the power source for innumerates and socialists” (yesterday). Commentators such as Bernard Keane have predictably and quickly raced to knock down any suggestion that Australia might need to broaden its decarbonisation portfolio beyond the current wind and solar orthodoxy. This orthodoxy necessarily requires the concept of baseload demand to be somehow defined out of existence or otherwise negated. But rumours of the death of baseload have been greatly exaggerated. Looking at their fine print invariably reveals truly massive reliance on technologies that are either highly problematic for a whole bunch of reasons (biomass), unproven at scale (concentrating solar thermal, geothermal) or cheating (gas), all of which look very much like baseload-type power sources, says Decarbonise SA.
“One of the inescapable conclusions from the global literature is that the studies serve to reinforce, not undermine, the relevance of baseload … What the ‘baseload myth’ demonstrates is one of the great flaws in our electricity discussions: the belief that demonstrating we could run on renewables-only is equivalent to establishing that we should.”
The key quantity is not cost per kW, but cost per kWh. One little letter, very big difference. The Lazard report cited by Keane states prominently “does not take into account reliability-related considerations (e.g., transmission and back-up generation costs associated with certain Alternative Energy generation technologies)”. The much-ballyhooed drop in photovoltaic panel costs takes no account of implied battery or other storage costs, which turns out to be critical. Lazard also assume a lifetime of only 40 years for nuclear reactors; the American Physical Society recently called for their licence periods be double that. This would have a big impact on the levelised cost of energy numbers.
Missing from the Keane analysis is any examination of just what paths will take us to the decarbonisation required, if nuclear is excluded. Even taking the worst case picked (Flamanville), the cost of replacing Australian fossil electricity generation with nuclear comes in at comfortably less than the most optimistic 100%-renewables scenario.
The first production figures for by far the largest example of primary ‘base-load solar’ technology (concentrating solar thermal) are in, and the news is not good. The 392 MW Ivanpah plant is only producing about a quarter of what it was expected to, and other than something about ‘weather’, they don’t really know why:
The technology is manifestly not ready, which means it will never come close to matching France’s nuclear-powered near-total electricity decarbonisation rate (little more than 20 years) in a similar time frame starting now.
This is undoubtedly one of the reasons why engineers from major Ivanpah investor Google tasked with making renewable energy competitive with coal recently announced “Trying to combat climate change exclusively with today’s renewable energy technologies simply won’t work; we need a fundamentally different approach”.
Mark,
Since when has 75% (the proportion of French electricity from nuclear) become ‘near-total’?
Wayne, by ‘near-total’ I was alluding to the fact most of the rest is hydro, so over 90% of French electricity is low-emission. I accept I could have made this clearer.
@ Mark Duffett – There is NO way you are ever going to get agreement from the Oz population that we should ‘go nuclear’.
The Japanese experience is enough to give everyone the raving horrors. We don’t want even the possibility of that happening here, thank you very much!!
Australia is said to be the perfect country for renewable energy. If as you say, the current systems are not quite good enough to provide base-load power, just await until next week and someone will come up with a better idea.
Things are moving so fast in this arena, it is impossible to believe that the problems cannot be solved in double quick time!
As for Julie B, what would she know about anything!!
Mark,
So 90% is ‘near total’?
Wayne, a bit over 90%, but yeah, I’m fine with that phraseology. In any case, the main point stands: nothing else gets within cooee as a decarbonisation success story.
CML, the horrors of the Japanese experience (apart from the obvious, infinitely worse yet now seemingly forgotten tsunami and earthquate) were the thousands of unnecessary and prolonged evacuations fleeing radioactive element concentrations much less than those lived happily and healthily amongst in other parts of the world. These overcautious to the point of panic evacuations led directly to hundreds of premature deaths. No casualties from radiation.
