Complaint about misleading Helen Caldicott article in “The Saturday Paper”

Guest Post by Geoff Russell. Geoff recently released the popular book “Greenjacked! The derailing of environmental action on climate change“.

Preamble Following a recent article by Helen Caldicott in The Saturday Paper I submitted the following complaint to The Australian Press Council. Unfortunately TSP isn’t a member of the Press Council. Nonetheless they were kind enough to review my complaint and informed me that op-ed articles are judged rather differently from news reports and that even if TSP were a member, they would take no action. Given the high number of factually incorrect claims by Caldicott, I asked for an example of a false or misleading claim that would warrant Press Council action. None was offered. Accuracy features strongly in the Press Council General Principles, but where nothing is inaccurate enough to warrant censure, then it hardly matters what they claim to give a damn about.


Helen Caldicott is a well known ex-pat anti-nuclear activist. She recently (30/5) published an article in The Saturday Paper called “SA’s short-sighted view of uranium and nuclear options”. It’s some 1700 words long and a written in a gish-gallop debating style, packed full of technical jargon, sweeping and unsupported claims. (Editorial note: It was a similar performance by Dr Caldicott that turned George Monbiot’s opinion on nuclear around, as explained here and referenced in the blog post’s lead image above). It would have taken many thousands of words to respond to all of its claims, so rather than do that I wrote a 1300 word response which explains in lay language enough of the modern scientific picture of DNA damage and disease to explain why Caldicott’s three decades of predictions of nuclear catastrophe have failed dismally. I thought concentrating on explaining basic principles was preferable to a blow by blow rebutt al. That she is wrong matters less than understanding why.

Erik Jensen of The Saturday Paper rejected the piece saying they didn’t have space and suggested I submit a 100 word letter instead. I later found out that he had also rejected a response from Ben Heard who was named and subjected to an ill-informed hatchet job in the article. Ben subsequently gave up arguing with Erik who refused his reasonable requests for a proper response. Instead, Ben published a piece on his DecarboniseSA blog.

I decided instead to make a complaint to you, The Press Council, in the hope of getting an apology from The Saturday Paper both for publishing an article so clearly in violation of the Press Council General Principles; an article replete with misinformation and the omission of key facts. I also want TSP to publish a suitable response to Caldicott’s article; something of similar length.

I’d be happy, if required, to send the Press Council a copy of the original piece I sent TSP; but what follows is a more clinical blow by blow analysis of Caldicott’s misinformation and why it breaches Press Council Principles.

About the article itself

As I said above, dealing with a 1700 word article with sometimes multiple mistakes per sentence is a big job, so I’ll restrict myself to the most important examples which I believe violate the Press Council’s General Principles. Indented paragraphs are quotes from Caldicott’s article.

  • [MISLEADING: solar farms use far more concrete] Construction of the huge reactor complex adds substantially to global warming as it is largely made of concrete – a CO2-intensive product.

This is misleading because it omits a key fact, namely that nuclear power plants require considerably less concrete (and steel) per unit of energy than either a solar or wind farm.

For example comparing materials per megawatt hour for the Spanish Andasol I solar thermal farm in comparison to a Westinghouse AP1000 nuclear reactor shows the solar farm uses 15 times more concrete (and 75 times more steel, not to mention 2,530 times more land). And this is a generous comparison, because the reactor will last twice as long, so you’ll be building the solar farm twice.

  • [MISLEADING: irrelevant] …[a] 1000-megawatt reactor requires one million gallons of water a minute, for cooling.

Again misleading. Most nuclear reactors use water for cooling, just like all thermal power stations, whether they be coal, gas, biomass or solar thermal. Any power plant which heats water to drive a turbine is most efficiently designed using lots of water for cooling. But it isn’t strictly necessary, it’s just more efficient than air cooling. Typically, many nuclear plants are on the coast precisely to make use of the water because water cooling provides efficiency gains. You may not have this flexibility with coal or solar because the former need to be near mines and the latter need to be on cheap land, which isn’t normally coastal. The amount of water required has nothing to do with whether a plant is nuclear but on its thermal efficiency and the ambient temperature of the water. Continue reading

Solar Impulse; and other comedies

Guest Post by Geoff Russell. Geoff recently released the popular book “Greenjacked! The derailing of environmental action on climate change“.

Many nuclear supporters tend to shy away from overt criticism of renewable technologies because they are confident that in any objective analysis, unencumbered by radio-phobia, nuclear will dominate any effective response to climate change; should the world choose to give a damn. After all there is no shortage of very careful objective treatments that support such a view. But every so often the solar industry, in particular, shoots itself in the foot with a spectacular demonstration of just how bad this technology is and it behooves us all to call a spade a spade and a lemon a lemon.

I’m talking about the Solar Impulse circumnavigation project.

The Solar Impulse is a solar powered aircraft consisting of more than 17,000 solar cells and 633 kilograms of lithium batteries packed into a plane with a wingspan longer than a Boeing 747. Not to mention a cast including 80 engineers, 100 advisers, a 12 year construction time, sponsorship from 80 companies including Google, a real-time website, T-shirts and of course, the obligatory baseball caps. But my personal favourite, because the project hails from Switzerland, has to be the Victorinox commemorative pen knives which will get confiscated should you try to take them on-board a real plane.

How will Solar Impulse compare with Around the World in 80 days? That was a pretty good yarn, written by Jules Verne in 1873. But Verne’s story is fictional. Phileas Fogg didn’t exist and never really attempted to circumnavigate the world in 80 days to win a rather large bet. While it never happened, it did, apparently, create intense publicity at the time because people thought it was really happening. Which neatly mirrors, or perhaps I should say “heliostats”, the renewable energy “revolution”.

Some 140 years after Verne’s book, the Solar Impulse is definitely non-fiction. You can watch it in real time and buy stuff. The initial leg of the journey was on March the 9th and, as I write (May 31), they’re about to take off across the Pacific. Here’s a table of the legs completed so far and the other 6 listed on the website:

By my reckoning they’ll be about 5000 km short of a circumference, but we’ll let that slide. My real interest is how they managed to sell this as an achievement. In 2008 Mark Beaumont cycled around the planet in 195 days pedalling 29,000 kilometers … presumably with some shipping. That’s seriously tough. But it’s no feat of technology and doesn’t demonstrate a superior mode of locomotion or foreshadow a global shift to pedal power.

Does the Solar Impulse demonstrate a superior mode of transport? Does it herald a future of solar planes? Don’t be daft. It’s slow, expensive, risky, fragile, dangerous and the total payload delivered by all those panels and batteries and dollars is just a single person; the pilot. If there were ever a Solar Olympics, the motto would be something like slower, lower, and weaker.

Tunnel Vision at the Climate Council

GR_April2015_CCCGuest Post by Geoff Russell. Geoff recently released the popular book “Greenjacked! The derailing of environmental action on climate change“.

The Climate Council has a new report out. The Global Renewable Energy Boom: How Australia is missing out (GREB) is authored by Andrew Stock, Tim Flannery and Petra Stock. The lead author is listed on the Climate Council website as a “Non Executive Director of several ASX listed and unlisted companies in the energy sector, ranging from traditional energy suppliers to emerging energy technology companies.” He’s also a chemical engineer.

Page 6 of the report begins by claiming “Globally, renewable energy’s contribution to global capacity and generation has climbed steadily upwards (Table 1)”.

Here’s line 4 from Table 1 except that I’ve added a column in red for 1973 using data from the IEA:

The percentage isn’t so clearly “climbing steadily upwards” now is it?

This table is one of a number carefully chosen or designed to enhance the images of wind and solar power and to misleadingly exaggerate their ability to prevent further destabilisation of the climate.

Misusing words

Page 8 follows with a claim in a large red font: “Global wind and solar capacity is growing exponentially”. This is accompanied by a graph which I’ve repeated here; but with a few annotations … in black. I’ll discuss them later.

Who think the graph supports the claim? It doesn’t. Exponential growth, by definition is growth with a regular doubling time, not regular increments … big difference! Growing exponentially is pretty easy for something trivially small, but it soon becomes hard and the graph shows clearly that both wind and solar are now only growing linearly; after about 2010 for solar PV and 2008 for wind.

The lead author is an engineer, so why call something exponential growth when it isn’t?

As the wind and solar contributions to an electricity grid grow, engineers expect stability problems to which there are currently no answers. AEMO’s 2013 report into 100% renewable electricty in Australia recommended underpinning wind and solar with either a biomass or geothermal baseload system to reduce the volatility; the sudden swings in supply. Germany obviously understands this and is now just burning half her forestry output annually. That’s about 30 million tonnes. This provides more electricity than either wind or solar.

Germany certainly had exponential growth in both wind and solar for some years, but that’s long gone. It took just one year to double the PV output for 2005; but the output from 2011 still hadn’t been doubled by the end of 2014. This slow down is despite solar providing just 6 percent of electricity. The wind power growth slowdown is even more advanced; it took eight years to double the 2004 wind output. Closer to home, South Australia has a higher renewable penetration than Germany, but no biomass baseload component, hence the stability risks which I suspect are behind the back-flip by long time nuclear opponent Jay Weatherill with the establishment of a Royal Commission into (almost) all things nuclear.

Understanding renewable growth

But am I being too cynical? The wind and solar growth lines above still look impressively steep. How can that be when Table 1, in contrast, shows a negligible percentage growth between 1973 and the present?

A path to energy nirvana, or just a circuitous detour?

Guest Post by Geoff Russell. Geoff recently released the popular book “Greenjacked! The derailing of environmental action on climate change“.

My previous BNC post started with a story about satnavs, those great little replacements for a dog-eared street directory. Everybody understands the value of planning a route. Everybody understands that just because a road is heading in the general direction of your destination, it may not be good choice; let alone the best choice.

It might be a dead end or take you on a long circuitous route to or past your destination. Everybody knows this but when it comes to climate change, it’s as if basic smarts take a holiday and anything that can demonstrate a CO2 savings (i.e., heads in the general direction of a solution) produces cheering and cries of victory. The article went on to show that we’ve wasted over a decade with biofuels because they demonstrably cannot decarbonise our transportation system. Not ever. It was an easy argument; a slam dunk, a lay down misere.

But what about renewable energy? Specifically wind and solar? Are these dead end technologies? It certainly isn’t a slam dunk, but lets examine what’s been happening in South Australia for the past decade.

On Sunday the 8th of February, South Australian Premier Jay Weatherill called for a Royal Commission into all things nuclear after a long political history of being anti-nuclear and after being heavily involved in the past decade of wind and solar roll outs in South Australia.

This launched a small flurry of opposition with Greens Senator Mark Parnell rejecting the call with claims about any involvement in the nuclear industry by SA leading to dirty bombs; SA Conservation Council CEO Craig Wilkins invoked a threat to our clean food image. Following an op-ed by me in the Adelaide Advertiser, Wilkins followed with a letter claiming that SA couldn’t possibly have a nuclear reactor within 10 years, and went on to say that (Advertiser Letters 18th Feb):

credible commentators are suggesting that SA could be 100 percent renewable in 10 years

Why have nuclear inquiry if success is imminent?

What on earth is going on? If SA could have 100 percent of its electricity being generated by renewables in 10 years, I’d certainly be cheering and dancing in the street. And what’s with Weatherill? Doesn’t he have any “credible commentators” on his staff? Or is he getting advice from real engineers instead of credible commentators.

Let’s look at the numbers.

First a couple of interesting graphs from AEMO’s 2014 South Australian Electricity Report.

The graph shows exports and imports of electricity into SA. After a steep decline in 2006, we see a gradual rise in imports of electricity starting in 2007. Why?

Satnavs, biofuel and climate change

Guest Post by Geoff Russell. Geoff recently released the popular book “Greenjacked! The derailing of environmental action on climate change“.

Even if they don’t own one, most readers will have seen a Satnav, those miracles of modern technology which will direct you across town to a suburb and street you’ve never been to before. After you enter your destination, there’s a little pause and perhaps the screen displays a message like: “Calculating…”, and then the instructions start.

Okay, so why the pause?

Once it’s located its required satellites and knows where you are, the Satnav runs some form of shortest path algorithm to work out how to get to the destination. If you are interested, here’s a walk through of one popular algorithm in action.

Really impatient people might be annoyed by the pause. For such people, there’s a much faster way of proceeding which would make that pause so short as to be imperceptible. Here’s the algorithm for a no-pause Satnav. First make a list of each road passing through your current location. After all, you have to travel down one of these. Then consider some point a small distance (say 30 meters) away on each of the roads. It’s high school maths to determine if this point is closer to your destination than your current location. If it is, then off you go. Then at the next intersection of any kind, do the same thing again. The algorithm would be lightning fast, the pause would vanish, and it always takes you in the direction of the destination.

At this point you should get out a piece of paper and start doodling. Might the algorithm use dead end roads? Ah … yes. If you go down one, can you ever get out? Ah … no. Consider roads slightly less than tangential to a circle around your destination. Might the algorithm take them? Ah … I guess so. Could you end up driving backwards and forwards along such a road forever? Ah … yes, theoretically.

Obviously, the algorithm sucks; even though at each point it always chooses a road that takes you toward the destination. But it can suck even it doesn’t make any of the mistakes I mentioned. It can suck by simply taking a hopelessly circuitous route.

If you think about it, this algorithm is pretty close to the current international approach to tackling climate change. Of course, a Satnav is just for one person, but the climate change mitigation process is highly parallel, so it’s like everybody involved is using this same sucky algorithm.

How often have you seen news stories about some so-called climate friendly project; they all have a prominent claim somewhere like: “This project will deliver clean energy to Y thousand homes!” or, “This project will save X tonnes of CO2”? All such claims tell you is that the project is taking you somewhere closer to zero-carbon nirvana. They tell you nothing about whether you will ever get there or how long it might take.

Consider as an example: the on-going global roll out of biofuels.
