The Australian
ALMOST 150 suspected rorts of the Gillard government’s Renewable Energy Target scheme were reported to the regulator last year, with NSW and federal authorities assisting with the execution of two search warrants as a part of the probe.
The Clean Energy Regulator yesterday released its annual report to government on the administration of the RET — a scheme that provides certificates for both large and small-scale renewable energy generation as part of the bipartisan target of ensuring 20 per cent of Australia’s electricity comes from renewables by 2020.
The regulator’s audit report revealed that during 2012 it received 147 allegations of rorts, the majority of which related to the creation of dodgy certificates for rooftop solar panels.
So far three “monitoring warrants” have been executed by NSW and Australian Federal police. One matter is before the Federal Court as a civil prosecution. One criminal matter was heard last year.

Not a good news week for wind power.
First windpower probably doesn’t produce as much electricity as people though it could. If the new estimates are right, humanity would need to cover 3 million square kilometers of the Earth to get just 10% of our electricity from wind. (And how many storms will that prevent do you think?) Could the “cure” be worse than the condition?
Second, it appears that wind turbines in the ocean might snap like matchsticks in particular conditions — conditions that are different for each turbine and at the moment, impossible to predict. The authors explain that it doesn’t have to be big waves or big storms — medium sized waves were the worst.
Windpower’s theoretical maximum isn’t what we thought it might have been
When we account for the wind shadows that large installations produce, at best, wind power may only give us 1 Watt per square meter (or 1 MW per square kilometer). According to this team our global energy needs are in the order of 30 terawatts, and one terawatt is one trillion (1012) watts. If that is the case, to to supply 10% of our global energy needs we’d have to cover… […]
Two wind towers are down in the last week in the UK 18 miles apart (Devon and Cornwall). It was thought the first tower (a six story £250,000 tower built in 2010) collapsed in the wind:
“The bolts on the base could not withstand the wind and as we are a very windy part of the country they [the energy company] have egg on their face,” she said. “There are concerns about safety.”
But, suspiciously, bolts were missing from the base and the second tower collapsed not far away. Sabotage is suspected. Who knows? The first tower was supposed to last for 25 years, and withstand winds of 116 mph. The night it fell, winds were only about 50mph.
There was fierce local opposition to the wind turbines. People do hate those things. That said, tampering with them would be a criminal act and also, logistically, possibly difficult to manage (according to some commenters on the Tele’s blog, “almost impossible”). Accusing people of sabotage might be a convenient excuse for a company with “egg on their face”. In other words, we don’t know. Wind towers have fallen over before: There have been some 1500 incidents or accidents in the […]
How is this for a scary thought?
Tim Flannery says renewables will run the economy:
“What we can now see is the emerging inevitability that renewables are going to be running the economy…”
And I say: Prepare for economic armageddon. Picture an Australia where we all have jobs — jobs digging holes, mucking out the stables, and chopping those last few remaining trees down. We may lead the world installing chinese-made solar panels, but they won’t help us make anything that anyone else wants to buy. Anton gives us some numbers no one seems to have mentioned to Tim. Like, it takes 1,000 new wind towers to kinda equal one coal plant. – Jo

Get ready — this is how much the 25 most recent, powerful, high-tech wind plants generate. Not the red line — that’s how much electricity we used. Look at the expanse under the blue line — every bit of that (“bit” being the word) is all thanks to those brand spanking new wind turbines.

Victoria’s windfarms have saved virtually no coal from being burnt.
South Australian windfarms have saved 4% of their rated capacity in fossil fuels at a cost of $1,484 per ton.
That’s only $1,474 above the current price of carbon credits per ton in the EU. They are 96% useless, and cost 150 times more than necessary for what they do (except for the times they are more useless and more expensive).
The point of a windfarm is not so much to produce electricity but to reduce greenhouse emissions.
If we built windfarms for the electricity they generate, we’d be better off paying for reliable electrons from cheap brown coal, and using the savings to research a cure for cancer. The point in putting up expensive, infrasonic thumping towers of steel and concrete that kill eagles and explode bat lungs is because it reduces our carbon dioxide emissions, except that it doesn’t really.
Mechanical engineer Hamish Cumming has written a whopper of a report (though I can’t find an online copy of it*). Because Victoria doesn’t have much of a gas powered grid, it can’t take advantage of the […]

In June this year the UNEP report announced that Global Renewable Energy investment reached $257 Billion in 2011. It’s so large it rivals the $302 billion invested in fossil fuel power. But how much electricity do we get for all that money? When the details are pulled from the fog, a quarter of a trillion dollars appears to produce only about 3% of all our global electricity, and even less of our global energy. All that money, so few gigawatts.
The 2012 UNEP report “Global Trends in Renewable Energy Investment” compares the
“…despite an increasingly tough competitive landscape for manufacturers, total investment in renewable power and fuels last year increased by 17% to a record $257 billion, a six-fold increase on the 2004 figure and 94% higher than the total in 2007, the year before the world financial crisis.”
Renewables growth has slowed somewhat:
“Although last year’s 17% increase was significantly smaller than the 37% growth recorded in 2010, it was achieved at a time of rapidly falling prices for renewable energy equipment and severe pressure on fiscal budgets in the developed world.”
The last couple of quarters have not been good for […]
I’m away, so this is a good time for Guest posts. Here Tony explains that we need lots of electricity even while we sleep. I didn’t realize our electricity needs were so high at night. The lowest power use each day is still as much as 60% of the peak. That’s the base load at 3am, and solar panels and wind farms just can’t provide it. We can burn the odd $500 billion building hundreds of solar plants, but even then, we would have to go “medieval” for about 8 hours each night. Candles anyone? — Jo

AUSTRALIAN POWER CONSUMPTION LOAD CURVES
There’s a message in these two diagrams that underlies every decision about national energy.
Summer power curve – Time of Day versus power consumption (MW)
These two diagrams are the most misunderstood images in the whole debate — the Load Curves for actual power consumption. These two shown here are for the whole of eastern Australia (including Tasmania and South Australia).
The top diagram shows typical consumption for a day in mid summer (Monday 30th January 2012) and the second is for a typical mid winter day (Friday 22nd July […]
The collapse of the Man-Made Myth continues apace. You may not read headlines as such (at least not in major dailies) but all the signs are there.
People who we never would have imagined speaking against the Big Scare Campaign are now doing so. Key glaciers are not melting and corals are happy. Governments won’t tell you it’s over, but they are behaving that way (the Australian one excepted, due to an election fluke that gave the Greens the balance of power). The Catholic Herald headlined it: Is the ‘anthropogenic global warming’ consensus on the point of collapse?

Mini update: The carbon market is being referred to as “dead”. Johannes Teyssen, chief executive of Germany’s EON, urged policymakers to make fixes. “Let’s talk real: the ETS is bust, it’s dead,” Mr Teyssen said in Brussels this week, adding: “I don’t know a single person in the world that would invest a dime based on ETS signals.” [full story: Financial Times].

You know, the one comforting thing about the insanity going on in the UK is that Australia doesn’t seem quite so basket-case, suicidally silly. Actually that’s not really true, both countries are barking mad, but thanks to David Cameron its a little less lonely at the loony farm. Democractic dementia has company.
Exhibit A:
In 2008 Ministers were aiming to generate 20 per cent of the country’s energy from renewable sources by 2020. Professor MacKay explained back then, that to reach that, they would have to put wind farms over the entirety of Wales. How did the governing class respond? By 2011, the UK Coalition took that crazy renewable target and doubled it.
Exhibit B:
— Two thirds of Britain’s turbines are fully or partly owned by foreign businesses.
— Total subsidies paid to these non-UK owned farms is £523 million.
— The subsidies paid to local folk are handy for Dukes and whatnot, and those who have large estates (especially ones they don’t live on) who can pick up the £20,000 a year in subsidies — milked from people who don’t have large estates and are […]
A joint writing project: Jo Nova & Tony Cox,
based on an idea and research by Anton Lang (who writes as TonyfromOz at PAPundits)
It’s the paradox that will torture the Greens. What if the best way to achieve their environmental aims as well as providing jobs and power was to build more coal fired power stations? Imagine if we could reduce CO2 emissions by more than 5%, supply 24 hour baseload electricity, create jobs, and save thousands of square kilometres of Australian bush from industrial domination. Imagine if “New Coal” turned out to be the lowest cost alternative as well? Anton Lang has researched it, and Tony Cox has confirmed that the big numbers make sense with an Australian electricity company (who shall not be named). Selling the Carbon Tax in Neverland is already a public debate that’s pretzel tied in impossible contradictions, so what’s one more unlikely twist? Possibly, just enough to get us out of a knot, or at least enough to expose the real aims of the carbon reduction plan. Old existing large scale coal fired power plants in Australia are all twenty to forty years old. Major advances […]
UPDATE: The Inhaber Graph curve is discussed in 2015. Later work shows this curve may be too pessimistic, though the shape of it is largely correct, the numbers are not quite this dismal.
One windfarm: bad; ten windfarms: useless.
If we replace 5% of the power grid with windpower we could reduce our CO2 emissions by 4% or so. (If only there was some point to doing that.)
But here’s the non-linearity trap for the fans of green energy. If we replace 20% of the power grid with wind power, we don’t get a 16% reduction in CO2 emissions: we get about 2% reduction (give or take a lot). Indeed if we use enough windpower we might even increase CO2 emissions. Yes Coal + Wind = more CO2. Oh the irony. Quick, can someone email Julia Gillard?
A review of wind power’s success in reducing emissions of CO2 shows the folly of pretending that successful small wind and solar power units can be upscaled to replace a large part of our electricity grid. The major difference between a coal-burning future and a “clean technology” one turns out to have nothing to do with CO2 — instead, in a […]
Have you wondered just exactly how much money you could pay for the feel-good factor of knowing that your electrons came from fashionable sources?
Thanks to the Victorian government we can get the hard numbers in the Victorian Auditor General’s Report.
In a nutshell, most alternatives are 2-3 times as expensive, except for solar which is 5 times the price.
(Luckily at the moment, renewables only produce 3 – 4 % of all energy in Victoria. Be grateful. You Victorians could be a lot poorer.) As it is, it cost Victorians $415,000 to tell you this, but it may be the most effective money spent on renewable energy in the last ten years. (Though oddly they didn’t produce this helpful comparative graph below. I did that for free.)
The Full PDF
In 2002 the State government of Victoria decided to aim for 10% renewable energy by 2010. You can see how well that worked out for them:
The light blue line (at 10%) was what they were aiming for.
The report is 48 pages. Basically it found that nobody thought too hard about how these aims would be done. Nobody assessed how useful it was to […]
