Sustainable energy

This morning The Australian has front page: Climate target to cost $75bn.

AUSTRALIA’S best hope of making affordable but deep cuts in greenhouse gas emissions by 2030 to reach global targets is by using clean coal, nuclear and gas technologies rather than renewable energy sources.

It’s interesting to note that first paragraph includes clean coal and nuclear as solutions to reach that target. Neither of these technologies are available today. Clean coal is still just a dream (as the article says further down “Capturing and storing emissions from coal-fired power stations, if viable” – emphasis mine).

Nuclear will take at least 10 years to be introduced, even if the decision was made today to start down that path. That means that it will be 2015 at least before we’ll see the benefits. In fact the report suggests 2020 as the year.

The Australian goes on to report that the infrastructure cost for these technologies “could double the cost of electricity generation”. I’m sure that’s the high-end figure (thus the “could”). I’d like to know how they came to that conclusion – but it’s fairly well understood and accepted, by both the government, business and the public, that the cost of shifting our energy infrastructure is going to cost more.

Higher infrastructure costs present a two pronged problem: 1) it’s more expensive to create clean energy infrastructure than existing coal technologies, so the market is reluctant to invest unless there is clear incentives to do so; and 2) it’s going to cost more at the point of use (i.e. our bills will be higher.

Point 1 can be addressed by the introduction of a carbon tax, which is being considered by the government at the moment (I suspect as a result of the nuclear energy inquiry). This brings the cost of coal into line with competing clean technologies, by taking into consideration the environmental cost of burning coal.

Tim Flannery presents an interesting solution to point 2. He suggests that with though prices increase with the introduction of a carbon tax, the government can reduce PAYG tax by roughly the same amount. The government continues to receive the same revenue through the carbon tax. Tax the bad, not the good is the basic principle. The net result, he suggests, is that we, as consumers, will not notice the difference. Our bills will be higher, but the tax breaks would ease, if not neutralise the pain.

But there’s another measure that can be taken, one that often seems to be ignored: efficiency. If we use less, the overall cost to us is less.

When I started reading the article, the main question I had was who produced the report? The Energy Supply Association of Australia. From their homepage: “The Energy Supply Association of Australia represents Australia’s electricity and downstream gas businesses.” So in other words, the electricity industry. The industry has a vested interest in protecting their existing practices, which I suspect is why clean coal features prominently.

The article goes on to point out this interesting tid-bit: “The report uses lower cost estimates for clean-coal technology than the Switkowski review of nuclear energy in Australia and also assumes that nuclear technology is not available until 2020.”

Perhaps the Switkowski review used an inflated figure (which is plausible); or the electricity industry is citing deflated figures (which is also plausible). So, if clean coal technology does become possible, the actual cost is probably some where in between those two reports.

I think the chief of the ESAA hit the nail on the head with this quote:

ESAA chief executive Brad Page said the report, based on best available estimates of costs and technology changes, demonstrated the need to develop the widest portfolio of technologies possible to minimise the cost of greenhouse emissions cuts.

He also said that “Over the next 25 years, if you are seeking to achieve fairly deep cuts in emissions, then polices that favour a particular renewable technology are probably poor choices,” which I also agree with.

This is where a carbon tax can be effective – let the market decide the best solution. The government is pushing nuclear, but it shouldn’t push any one technology. However, where there is a significant public interest in not pursuing a particular technology (like dirty coal, or I would argue nuclear) the government should intervene, in my view.

WWF CEO Greg Bourne was quoted saying much the same thing: “WWF chief executive Greg Bourne remained opposed to nuclear energy and called for market mechanisms to accelerate the development of lower-emissions technologies.”

At least the Oz got WWF’s and Greg’s position on nuclear right this time 😉

As an aside, I wonder if a report was released showing that renewable energy could meet that need, would it be front page? Or do only controversial findings make the cut?

Reason I ask is that the Clean Energy Future reports, released a few years back by WWF, show how our energy requirements can be met with renewable energy and gas-fired power (for base load – not renewable, but with much lower CO2 emissions than coal-fired power). Is that not newsworthy?

Polls show that the public wants renewable energy, and believes that they are the way forward. Yet it seems practical solutions that exist today are ignored. Sigh…

4WD angst

A small part of me laughed at the photo for this: shopping channel launching ‘March 07’. Reminds me of the ‘Pajero’ naming issue – ‘Pajero’ apparently means ‘wanker’ in Spanish.

But then I thought: at least it’s dirty – maybe they actually used it off-road.

Which reminded me of a little jibe I’ve been using when I see a pristine clean 4WD in an urban setting: “Get it dirty or get rid of it…”. I don’t have an issue with 4WDs per se – if they’re used appropriately, I’m less opposed. But I find it hard to believe they are appropriate in urban settings most of the time.

Maybe I’m just getting cranky in my old age?

Open system innovation

Check out this Engadget video profile of the Sansa Connect MP3 player.

This is the type of innovation that can occur with the use and support of open systems. The Sansa uses Mono, an open source implementation of Microsoft’s .NET to implement some features, that on the surface at least, look pretty amazing.

Things like – sharing music between Sansa’s using wifi, internet radio integration and more.

Contrast this approach with Apple’s closed systems on the iPod and iPhone. Apple claims to be innovative – and they are. But if they opened the system others could innovate on their platform, increasing the value for the platform, and ultimately their customers.

OLPC in developed countries?

Eco-geek reports: $100 Laptop for You and Me Too!:

While the OLPC people are still focusing on making the laptops available to less developed countries, there has been some discussion about selling the laptop in developed countries. However, anyone buying an OLPC in America would have to buy a minimum of two. One for themselves, and one for a child in the third world. Sounds like a fantastic idea to me.

I have to agree – a great idea!


Another really powerful film I saw a little while back was Downfall – a German film about the last days of Hitler’s reign leading up to his suicide.

The film has received many accolades, so I was looking forward to seeing it. It’s a pretty impressive film, if only through it’s restraint. Hitler is often portrayed as this larger than life, devil-incarnate character. This film portrays a man who is deeply troubled, and deeply flawed – but without the over-the-top dramatisation.

The film is set in Hitler’s bunker. One of the strange things I found is how everyone was going to great lengths to make the bunker feel normal. The decor was very much modeled after a house – not the concrete bunker I would expect.

But the other thing that I found amazing is that no-one topped him in those final days. As it’s portrayed in the film, it’s clear he’s completely lost the plot, and that even his closest allies realise it’s all coming to an end.

It’s a very good theme – I definitely recommend it.

Manufacturing Consent

A few months back now I rented the DVD of Manufacturing Consent, the documentary based on the classic book by Noam Chomsky and Edward S. Herman.

The production is pretty rough, but the substance is incredibly relevant even today. What I found most interesting about the film was how much of the “future of media” that was presented is now coming to fruition through blogs and internet-based activism. Anyone that’s read Jay Rosen’s PressThink blog probably won’t find a whole lot of new stuff here, but it’s still very good.

Chomsky, as always, is full of factoids and amazing examples that demonstrate the issues he sees in the media. But one quote really stood out to me. Unfortunately I can’t find an exact reference – but paraphrased, it went something like: history likes heroes – in history social movements are often attributed to individuals, but it is the social movements that make the individuals historically significant.

In other words, heroes are often born out of mass social movements, the heroes don’t create them – but our history presents things the other way around. Maybe if I get the DVD out again I can find the exact quote – I don’t think I’m doing it justice here (and if anyone knows the quote I’m referring too, please leave a comment)…

Renewable energy?

Geothermal Power Plant Triggers Earthquake in Switzerland. I’ve always been a bit dubious about this technology – it just strikes me that we don’t know enough about the Earth’s processes to be messing with transfer of heat energy from under the surface of the Earth for our own purposes. This article highlights the risks:

The engineers and officials of Geopower did inform the authorities and the public that the proposed Deep Heat Mining project posed a risk of triggering small tremors. Quakes of the magnitude actually experienced, however, were not anticipated.

It makes me worry even more about carbon sequestration plans.
