very interesting and highly recommended. I read it back in 2009 I think, it's since been updated a few times.
available to download for free on the authors website.

Dry but worth reading through. I'm now skeptical about any plan about Energy that "does not add up" like the author keeps repeating.

Windfarms are becoming big business in Australia and a Senate enquiry report has just come out looking at the implications, including, most importantly, health.

You can see the whole thing here: http://www.aph.gov.au/Senate/committee/clac_ctte/impact_rural_wind_farms/report/...

The aspect of health that is most likely to be affected by windfarms is the psychological and physiological debilitation resulting from noise pollution and the report observes, in attempting to hear from all interested parties:


The Committee did not receive any evidence from people who are living near the turbines and who are receiving recompense for the use of their land. The reasons for this are unclear. Several witnesses claimed that the host landholders are subject to 'gag' orders under the terms of their contracts with the developers. This was denied by the industry...


The report goes on to discuss the technical aspects of what is happening:


Noise measurement
2.32 The measurement of noise as used in the Standards is dB(A). This measure was explained as being appropriate because it simulates human hearing. Dr Warwick Williams, a Senior Research Engineer at the National Acoustic Laboratories, explained that the A-weighting heavily discounts the low frequencies and the very high frequencies. A-weighting discounts infrasound as it is below the level of human hearing.

2.33 Many persons who complain of the noise produced by wind farms refer to noise that lies within the low frequency range, and to infrasound (sound of less than 20 hertz). As discussed earlier, the 'thump' which apparently is produced by wind turbines and which causes distress to some people is a low frequency sound. According to the Sonus report, over large distances, whilst the absolute level of sound in all frequencies declines, the relative level of low frequency noise increases compared with mid and high frequencies. The Sonus report states that low frequency sound can be easily measured, and 'the C-weighting network (dB(C)) has been developed to determine the human perception and annoyance due to noise that lies within the low frequency range'

2.34 Mr Huson submitted that neither the C-weighting nor the A-weighting is appropriate for the measurement of very low frequencies:

If we were to investigate lower frequency sound levels from wind farms we cannot use the C-weighting or the A-weighting since these attenuate low frequency sound
2.35 Dr Geoff Leventhall, a British acoustics consultant, informed the committee that:

...as environmental noise control criteria are A-weighted, they tend to under-rate potentially problematic low frequency environmental noise. This has led low frequency problems to be left to continue, whilst higher frequency problems are fixed more quickly. As a result, where genuine low frequency noise problems have occurred, their continuance leads to the development of undue stress in those affected. There is also a body of very stressful, unsolvable noise problems, described as “low frequency” by those affected, where detailed investigations cannot discover a specific noise source.

2.36 The Noise Management Services report commissioned by Mr and Mrs Dean on the noise impact of Waubra Wind Farm suggested that:

There are many possible ways that low frequency sounds may influence the ear at levels that are unrelated to hearing sensitivity. As some structures of the ear respond to low frequency sound at levels below those that are heard, the practice of A-weighting (or G-weighting) sound measurements grossly underestimates the possible influence of these sounds on the physiology of the ear. The high infrasound component of wind turbine noise may account for high annoyance ratings, sleep disturbance and reduced quality of life for those living near wind turbines.


I don't understand why Australia seems to be moving away from solar, when it would seem to have the perfect conditions for it, and towards something that if nothing else, is both visually and aurally offensive.

I am also curious to know why it is that wind farms are set up in populated areas, sometimes in scenes that were previously of breathtaking beauty, rather than in all the empty bits. Is it because infrastructure exists in populated areas? I guess that's the obvious answer.

The report is 132 pages long. I have quoted just a tiny bit of it.

post-Japan

Been mulling this over for a while.

One of the ideas that comes from the advocates of nuclear generated power is that when we have an accident that will just be collateral damage.

This is from Manny’s review:


The chapter on nuclear power is also very good. As MacKay says, nuclear is dangerous, but it's not infinitely dangerous. Other kinds of energy are dangerous too. He tries to quantify the risk from nuclear to the best of his ability, in terms of the number of deaths you could reasonably expect per unit of generated energy; then he compares with other forms of energy. It's by no means clear that nuclear is, in fact, so dangerous… MacKay presents the figures dispassionately, and adds, in a typical aside, that you shouldn't conclude that he's pro-nuclear; he's pro-arithmetic.


It is kind of chilling reading it put like that, wouldn’t you say?

Maybe we do all agree that what’s happening in Japan is just arithmetic. But it is arithmetic we only want to see on Fox TV news. We don’t actually want to be there. A nuclear wastedump? Go THERE? Check me out now p-lease.

But this is Japan:

http://hakodatebirding.blogspot.com/

Isn’t it beautiful? This IS Japan. It is Hakodate, the same town we were in six months ago, it was flooded by the tsunami, the fishing industry is dead, but still, there is this.

Coming from Australia means I come from the country that is selling uranium while having as little as possible to do with it in our own country. Nuclear power? You must be joking. Australia has obvious alternatives in solar and wind, since most of the country is an uninhabitable desert of sun and wind. But I gather that in Europe nuclear power makes sense, you all believe in it over here. But if you believe in it, then part of that belief has got to be that you WILL go to Japan and see what it really is, not just what Fox News tells you it is.

Will you go to Japan? Now? If not, why not?

I’ve been discussing this lately with people partly because a friend runs an international music festival in Hakodate. Post-Japan almost all the overseas acts have pulled out. So, I did what an Australian would. I started writing to musicians in Australia asking if they would consider going. This is not good timing as the festival is in a few months and of course most musicians have their schedules organised a year or more in advance. But still, the very first person I wrote to replied straight away with yes, she would.

Then I noticed that our Prime Minister is in Japan at the moment, the first overseas leader to visit. She was just involved in a fund-raiser there with a name which will mean more to the average goodreader: Kylie. Quoting from ABC news: http://www.abc.net.au/news/stories/2011/04/23/3199065.htm

Kylie Minogue, in town for a series of concerts, was also guest of honour at the fundraiser, which raised about $140,000 for a Red Cross tsunami appeal through ticket sales alone.
She is one of the few international acts who decided to continue the Japanese leg of their world tours, with many others cancelling because of the ongoing Fukushima nuclear power plant disaster.


I don’t know what this says about Australians compared with the rest of the first world. I can’t help compare with this, from a blog here: http://concordnanae.com/:

Dear friends and family,

As of March 24th I will be taking a temporary leave of absence from my job in Nanae, Japan. The current plan is to abscond to Hawaii on standby, with the intention to return to Japan on April 3rd. If, however, the nuclear crisis in Fukushima remains as nebulous as it is right now, I will likely extend my stay and will consider returning to Concord to continue my work as Coordinator of International Relations from there in our American sister city.

Experiencing this terrible tragedy firsthand has been a life-changing experience. I have grown as a journalist, a government employee, and most of all as a person, and have been awakened to the full depth of my appreciation and love for Nanae. My heart remains with the Japanese people during this tense time, and I ardently hope that we will be reunited very soon.


That was April 3 and the blog hasn’t been updated since.
Kind of ironic that this is from somebody whose job title is ‘Coordinator of International Relations’. I just don’t quite get how the words fit in with the actions.

There are millions of people in Japan who have to live with the consequences of arithmetic, who are what we like to call collateral damage. I’m wondering if the difference between them and the first world people who are happy to support the idea that nuclear catastrophe is arithmetic, is that we all have the agency to flee it. Maybe it is the rich people of the world who see nuclear power as necessary and the defects as collateral.

Of course, complicating this view is that the Japanese themselves are still remarkably isolationist. I have no idea if they even notice that we are not going there, and if they notice, I don’t know if they care.

Later still.

Written at the risk of incurring the ire of Paul.

The issue was raised on Manny's review of this book as to whether it was possible to sell the idea that we should be wearing chunky warm sweaters and that if only we'd all do this, practically all the problems facing us would be solved. Or something like that...sorry, I like to be extravagant.

Can warm jumpers look sexy? If I was a boy I'd think all these were:

Urusula:



Jean:



She's so gorgeous I have to give you this one too:



When I was little I really wanted to grow up to be Julie because it seemed like the obvious way to get Christopher Plummer to fall in love with me:



Well, I don't see why the good example of these girls can't save the planet for us. If anybody can.

------------------------------

Later.


"If some sense of moderation cannot check the raging avarice which without concern for mankind increases and grows by leaps and bounds--we will not say from year to year, month to month, or day to day, but almost from hour to hour and even from minute to minute--if our regard for the people's welfare could tolerate unmoved this mad licence from which in such a situation the people suffer in the worst possible fashion from day to day, some ground perhaps would be found for concealing the truth and saying nothing. . . ."


I guess that might have been written yesterday, but actually it was Diocletian during the fall of the Roman Empire.

What is the difference between us and all the other civilisations that have, at their apex, destroyed themselves? Ours is the only one that built the capacity to take the whole shebang with it. It must be really irritating to people who live in straw huts and walk everywhere that they are going to go too.

-------------------------------------------------------------------

Thoughts-in-progress.

Look at this:

Campaigners also mislead. People who want to promote renewables over nuclear, for example, say “offshore wind power could power all UK homes;” then they say “new nuclear power stations will do little to tackle climate change” because 10 new nuclear stations would “reduce emissions only by about 4%.” This argument is misleading because the playing field is switched half-way through, from the “number of homes powered” to “reduction of emissions.” The truth is that the amount of electrical power generated by the wonderful windmills that “could power all UK homes” is exactly the same as the amount that would be generated by the 10 nuclear power stations! “Powering all UK homes” accounts for just 4% of UK emissions.


That's a fabulously dishonest piece of promotion, I must say.

What about this statistic:

p. 100

The financial expenditure by the USA on manufacturing and deploying nuclear weapons from 1945 to 1996 was $5.5 trillion (in 1996 dollars). Nuclear-weapons spending over this period exceeded the combined total federal spending for education; agriculture; training, employment, and social services; natural resources and the environment; general science, space, and technology; community and regional development (including disaster relief); law enforcement; and energy production and regulation.


I've read this paragraph a dozen times and I'm still gobsmacked. It's like some bizarre sci-fi story. The idea that it is the real world, the real expenditure of a Western democracy, beggars belief.

Another fascinating statistic:

p. 221

According to the Stern review, the global cost of averting dangerous climate change (if we act now) is $440 billion per year ($440 per year per person, if shared equally between the 1 billion richest people). In 2005, the US government alone spent $480 billion on wars and preparation for wars. The total military expenditure of the 15 biggest military-spending countries was $840 billion.


There is some discussion here of the nature of the market and whether it can be the tool via which climate change is meaningfully brought about.

pp. 224-5

What should we do to bring about the development of non-fossil energy supply, and of efficiency measures? One attitude is “Just let the market handle it. As fossil fuels become expensive, renewables and nuclear power will become relatively cheaper, and the rational consumer will prefer efficient technologies.” I find it odd that people have such faith in markets, given how regularly markets give us things like booms and busts, credit crunches, and collapses of banks. Markets may be a good way of making some short-term decisions – about investments that will pay off within ten years or so – but can we expect markets to do a good job of making decisions about energy, decisions whose impacts last many decades or centuries?

If the free market is allowed to build houses, we end up with houses
that are poorly insulated. Modern houses are only more energy-efficient thanks to legislation.


Well, not really. The market, like the democracy is no more than the reflection of our wishes. We can't blame the market, any more than we can blame our politicians. Both are doing what we want.

What we have to change is not the market, not the politicians, but ourselves. The rest will follow. But unfortunately we all have the pathetic 'little old me can't do anything on my own and so I will do nothing' attitude which lets us carry on doing the wrong thing ad infinitum. And so everybody does nothing, whereas if they all did something, that would add up to quite a bit. It is plain wrong to say that doing something isn't enough. Just setting an example is something. Fighting the good fight is something. And that will be catchy. If we do the right thing, the politicians and the market will do the right thing too. Stop blaming systems and institutions and others. Take responsibility, each and every person. It is your fault, my fault, our fault.

If we want the market and the politicians to do the right thing, at least behave in a way that lets them understand that.

Still, the fact is that democracy is uniquely unqualified for the task at hand. The whole point of democracy as it is played out in practice in most of the world is that I say 'yes' and you say 'no'. It is how it works. Well, if you call that working. Nothing, including as we can see now, the end of the world, is going to change that.

We need a benevolent dictator, somebody at the top of the world whom we permit to be in charge. It is obvious from reading this book that if we did that now, with not much money and not much time invested, there is the distinct possibility that we would save ourselves. I'm voting for Bill Clinton. If he sorted out the US economy, surely this will be a piece of cake for him. Even when he's lying you feel like you can trust him. He has an equally good micro and macro eye. He knows an awful lot. He's fair.

And, just addressing the girls in the audience, who wouldn't want to not have sex with him? Or is that just in my head because I'm not getting enough?
