““The green transition in Denmark has stalled right now”
Denmark was the posterchild for the wind industry. It has the largest share of wind power in its national grid, and is home to the industry giants, Vestas and Orstead — two of the world’s largest wind-manufacturers . Denmark is planning a large expansion in wind energy (or it was). But when the government offered up three areas of the North Sea that were described as “among the best in the world”, the deadline came and went last Thursday and not a single bid was received.
Wind energy is free and no one wants it…
This is a huge shift from the situation in 2021 when there were so many bids for one wind plant, it ended up being settled by a lottery.
Denmark Gets No Bids in Largest-Ever Offshore Wind Tender

The lights went out in Broken Hill. A storm blew seven transmission towers over disconnecting the area from the national grid on October 17th. About 19,000 people live there, and with a 200MW wind plant, a 53MW solar array and a big battery, plus diesel generators it was assumed they’d be OK for a while without the connection to the big baseload plants, but instead it’s been a debacle. They’ve had nearly a week of blackouts with intermittent bursts of power, barely long enough to charge the phone.
The fridges in the pharmacies failed, so all medications had to be destroyed and emergency replacements sent in. Schools have been closed. Freezers of meat are long gone… Emergency trucks are bringing in food finally and hopefully the schools will reopen today. But the full reconnection will not happen until November 6th.

The clean green future doesn’t have much room for wilderness

John Constable puts some numbers on The terrifying scale of the green revolution in The Spectator this week.
Ponder just the scale of the Sophia Offshore industrial wind plant being built off the UK. The wind is free, but to collect enough of it to power 2% of the country, the UK will have to build 100 wind turbines, some 200 kilometers out in the North Sea. Each blade is 108m long and weighs 65 tons, or about as much as a semi-trailer. When the wind blows hard enough, about 200 tons of matter will rotate above the ocean. The box holding all the spinning parts together weighs another 500 tons and needs to be suspended 140 meters up in the air over the waves and during storms.
Each of the 100 turbines will reach 250 meters high, which is “only 60m short of Britain’s tallest building”. So much effort and so little to show for it.
To make sure the whole thing doesn’t fall in the drink with the first stiff breeze, the turbines need to be weighed down with more than a thousand […]

The Crash Test Dummy Nation wins a Gold Medal in Electricity Prices
And you thought last week was bad. While the single spike at $17,000 a megawatt hour in five states simultaneously was a record, just a week later we have the double spike bonfire — peaking at breakfast and dinner on the same day in our two largest states. That’s a high degree-of-difficulty (to pay the bill). This was not just a 5-minute bid rocket — it was 90 full minutes of blitzkreig twice in a day for both NSW and Victoria. With admirable supporting efforts in burning money in Tasmania and South Australia for breakfast, and then in Queensland, which joined the financial bonfire for dinner.
The average price for the whole 24 hour period of August 5th was eye-watering. Last week the spike flattened out to about $300 per megawatt hour across the day. But yesterday in NSW and Victoria, the average price was $2,150 across both states for 24 hours in a row.
It’s possible the AEMO will have to take over the market again in some states to put the fire out.
Welcome to renewable hell
At both peaks Victoria was burning […]

It wasn’t supposed to be this cold and windless in Australia
For some reason that no climate model can explain, Australia has run out of wind power three months in a row, which means we had to use more gas than expected. It’s also been colder than climate models predicted, despite global emissions being higher than ever in history. For some other reason that no rational adult can explain, the State of Victoria banned gas drilling for most of the last decade (to reduce the beachy-weather days in eighty years) and thus, as night follows day, the state is running out of gas. Ergo, predictably, it is also facing blackouts, cost blowouts and manufacturers dependent on gas are warning they may have to close down, or move to the US, where gas is still cheap.
If only the climate models could predict temperatures and wind even a month in advance?
The AEMO (our electricity grid manager) says Victoria will run out of gas before winter runs out of bite. Apparently Victorians are pulling twice as much gas out of their main storage as they can afford to at the moment. Not only does Victoria need the […]

How much back-up do we need for our 11.5 gigawatt wind system? About 11.4 gigawatts.
Wind energy failed on Thursday at what must be close to a record low — with barely 88MW of production from 11,500MW of wind turbines. That’s about 0.7% of total nameplate capacity.
With construction costs running at $2 million for every theoretical megawatt of turbine, that’s $20 billion dollars of machinery sitting out there in the fields and forests of Australia producing about as much as two diesel generators.
We have 84 industrial wind plants across 5 states of Australia, and the green band below was their total contribution to our national electricity needs on Thursday — put your reading glasses on.
Anero.id
Things were even worse in Western Australia, where at the one point that afternoon when I happened to look the state’s total wind generation was minus 11MW. Some wind turbines were drawing a megawatt here and there, perhaps to keep the turbines rolling so they don’t get flat spots on bearings.
It was an attack of another climate-denying high pressure cell on Thursday. There was no place in Australia good for wind generation except (maybe) for our […]

But who needs radar right?
We found out last year that offshore wind turbines scramble Air Force Radars. RAF pilots already use the turbines in training exercises to help them hide. But ships also use radar and a new study quietly reported a couple of years ago that offshore wind turbines will interfere with shipping radar, may cause collisions, and interfere with search and rescue. The 2022 report was from the National Academies of Sciences, Engineering, and Medicine in the US.
But it’s OK right, we just need to upgrade all the old radar systems, keep boats out of the area, or wrap the blades of the turbines in the same material we use on stealth aircraft. (That will add to the costs of wind power). No doubt GPS and AI systems can help, but radar adds an independent and well developed layer of safety. Who wants to purely rely on the satellite connection on a stormy night?
And after we’ve built all the wind towers, upgraded the boats and planes, then we can build the second and third generation of turbines and fill holes in the ground with the waste from the […]

There is no saving the Australian wind industry from a high pressure cell Right now 19 out of 20 wind turbines are essentially towers of fiberglass waste
Australia has built 11.5 GW of theoretical total wind power capacity on the National Energy Market (NEM) spread across 80 locations on the Eastern Seaboard, and at one point today only 4.1% of it was working. Another gigawatt of generation on the Western side is only generating at 3 – 5% capacity.
The green bar below represents total wind generation today compared to the total power consumed (the black line).
Total wind generation for the NEM in Australia.
The Australian government is telling us “we’re different” to other countries struggling to make wind and solar work. We supposedly have “world-class resources” and “natural advantages in renewables“. But we also have world-class high pressure cells that stop wind generation across the entire nation simultaneously. On days like these, it doesn’t matter much whether we have 1,000 wind turbines or 10,000 if 95% of them are failing.
Compared to Europe, we have a natural disadvantage in wind power — there’s no one to rescue us when we screw up. We’re […]

Games with levelized guesses don’t take all the hidden costs into account
Prize of the day for national policy research goes to Nick Cater, who managed to ridicule our billion dollar national science agency, the CSIRO, with a newspaper column.
The CSIRO put out a report proclaiming that nuclear power would be impossible before 2040 and cost “twice as much” as renewables. But Nick Cater just compared electricity in New South Wales to Finland to prove their 129 pages of modeled costs were wrong:
Finland’s clean, Green nuclear power a lesson for Labor
On Saturday…. Electricity generation in NSW was releasing 750g of carbon into the atmosphere per megawatt hour of electricity. In Finland, it was 35g.
If the CSIRO’s GenCost report is to be believed, Finnish electricity prices should have gone through the roof a year ago when its newest reactor was turned on. They did not. The retail price of electricity in Finland, which is indexed to the spot market, came down almost immediately.
Were Energy Minister Chris Bowen to spend a few days in Finland, he might realise almost everything he says about nuclear is complete […]

The more wind turbines we have the more useless they are
There goes those plans to cover the continental shelf with talismen to the Wind Gods.
New research shows wind turbines off the East Coast of the US could end up stealing as much as a third of the energy from other wind turbines downstream. And in some conditions, the turbulent wake they leave might stretch out 55 kilometers behind them. This effect is worst on turbines in the same “farm” but could even affect other wind farms a long way off.
The wake effect will be strongest in summer. We’ll just have to ask everyone to turn off their air conditioners then?
Scientific civilizations do this sort of research before they commit $10 trillion dollars, set up a trading scheme, and blow up the coal plants. Imagine if building a coal plant near another plant made it 30% less efficient on hot days…

Who knew high voltage cables running for kilometers in a deep electrolytic moving body of water would be expensive?

Despite offshore windfarms dealing in a kind of mechanical hell of high speed salt water spray, big waves and volatile wind conditions, surprisingly 85% of the insurance claims are because the underwater cables are failing.* If the subsea cables can’t be insured, it’s another unexpected cost threatening the economics of offshore wind.
The underwater cables needed for offshore wind are apparently so costly to repair, and the losses from lack of generation so steep, they are in danger of becoming uninsurable.
Subsea cable failures pose global threat to offshore wind
Energy News Live
The race to harness offshore wind energy has hit a significant roadblock, with the reliability of subsea cables emerging as a critical concern.
Global Underwater Hub (GUH) has raised alarm bells about the escalating issue of subsea cable failures.

Greens destroying nature again
Some experts think there may be only 1,000 of these eagles left, our largest bird of prey, and yet in the last 12 years some 272 of them have been killed or injured in the vicinity of Tasmanian wind towers. That’s at least as far as the maintenance crews have noticed, and not that they were specifically looking…
So the number can only go up, and other types of birds are getting the chop too.
The Tasmanian Wedge-tailed eagle has been known to have a wingspan as large as 2.8m (9ft 3in). They mate for life, and a single nest can be 1 – 3 meters across.
Tasmanian wind rush ‘may push eagles to extinction’, says study

The Year of Gloom continues for Wind Power
Wind energy is so cheap and profitable that last week, investors abandoned the annual UK auction to build industrial wind plants in the oceans around the UK. Exactly no one offered to spend money building turbines even though electricity prices are burning hot. Apparently prices for building the machinery to collect and transmit low density erratic energy are not “free” like the wind. Even after decades of advances, sacred green electrons still cost a lot more than war-afflicted-fossil-fuel electrons do.
The free market has spoken and it said “No”. At The Guardian though – it was, of course, all the Governments fault. That and the dreaded Hand Of Inflation. It’s so unfair:

The end of the naive era of hope in Wind Power fairies
Remember how they said wind energy would keep getting cheaper? Only a year ago academics were still writing papers about the “Moore’s Law” miraculous future of wind power. Only we appear to have already hit the point where bigger is not better. Two years ago the former head of Siemens bizarrely warned that “Wind power risks becoming too cheap” and Reuters, bizarrely, published it.
Meanwhile production costs are rising for the offshore variety too, and Siemens is scrambling to delay deliveries, so it can fix problems first…
The Washington Post, a big fan of the “Green transition”, puts in an admirable effort to make excuses for the bad luck of the wind industry — anything but admit that this failure may represent real mechanical limits to the collection of erratic, low density energy in the most hostile settings on Earth.
These machines are so fragile they cannot just sit under their own weight motionless, less they get permanent brinelling damage to the bearings. And tiny micro-oscillations can create False Brinelling.

It’s a bloodbath in the wind industry.
Despite the wind being free, collecting it appears to cost a fortune. Siemens Energy lost a third of its stock price on Friday. Just like that, seven billion dollars in market value disappeared.
Only a month ago they were expecting to break even, as the Wall Street Journal reports, the executives appear to have been blindsided by the rapidly escalating maintenance costs. The problem is so bad, and perhaps fundamental, that shareholders in other turbine manufacturers are selling out. Vestas Wind fell 7% Friday.

The promise was that wind turbines would keep getting cheaper as they got bigger and better. Instead, issues are appearing now even in new installations, and people are starting to wonder if they’ve made the turbines too big too fast. The bearings and blades are wearing out, and the costs to fix them are crippling.

Just another day of Wind turbine failure — 6GW in 16 hours
There was no cyclone, no storm, no national disaster, but our national infrastructure collapsed just the same. Blame a high pressure cell.
Last week TonyFromOz noticed that the output from all 79 industrial wind plants in Australia disappeared overnight from 6GW to just 0.4GW. Imagine if an entire state of coal plants failed in the space of 16 hours and nobody cared?
Wind plants fail all the time and wreak havoc on the grid. It’s just “business as usual” or rather “subsidies as usual”. The rainbow list of acronyms below the graph shows every single wind plant in five states of Australia was accounted for in this dismal tally.
Wind turbine failure: TonyFromOZ
Billions of dollars rests on whether we can stop high pressure cells forming near Adelaide…
As Tony points out, the more wind towers we build, the worse this mayhem will be. Weather comes and weather goes but when the doldrums hit, it wipes out all 79 industrial plants together. Only wind plants built outside the high pressure cell could smooth out this failure. Offshore wind farms would have failed at […]

Let it be known that the skeptics are, and always have been, the environment’s best friend. The Greens, sadly are the wilderness wrecking, naive minions of the Establishment Powers who will sacrifice whales in a quest to impress their industrial banker overlords. They tell themselves they are saving whales 100 years from now with the same windmills that kill the whales today.

Conservative watchdogs highlight ‘alarming’ surge in whale deaths as wind farms grow off NY, NJ coasts

“It’s gone from ‘Save the Whales’ to ‘Kill the Whales.’ And the green groups that have promoted Earth Day for 53 years are totally okay with this agenda.”
Committee for a Constructive Tomorrow president Craig Rucker said the push to build the wind farms comes “despite growing evidence that whales are being impacted by the preliminary sonar blasting being conducted to site windmills, as well as scores of the marine mammals washing up dead on beaches.”

Wade Allison has done a short but devastating analysis for the GWPF. The take home message is that the energy contained in the wind is diabolically more erratic than most people realize. It’s just basic physics and almost no one in politics seems able to comprehend just how impossible these numbers are. If only they would “follow the science” eh?
Thanks to Paul Homewood at Notalotofpeopleknowthat.
The exponential death of affordable electricity
It’s just physics. The power of the blowing wind increases by the speed of those particles cubed which produces a twin engineering nightmare. If the wind doubles in speed, the energy goes up by a factor of 8 (or 2 × 2 × 2, and we need to spell it out), and if it slows by half, the energy drops eight-fold. It’s bad both ways. At high speeds, the mechanical engineers have to turn off the turbines to protect them, and at low speeds the electrical engineers have to ramp up power stations that may not exist, or pray to Gaia for batteries that will never exist.
Allison has a graph showing the total output of all the wind turbines in the UK and Europe […]

Arecleoch Wind Farm | Mary and Angus Hogg.
While British people can’t afford to warm their own homes in winter some Scottish wind turbines are being rotated and de-iced with warmth from diesel generators which also leaked some 4,000L of diesel. Since this was due to a cabling fault, presumably the other shivering wind turbines are maintained with mains power?
If giant turbine blades sit still too long, the bearings can generate permanent Brinelling damage. Alternately micro-oscillations or vibrations can cause False Brinelling. Small metal fragments then grind more of the metal around it, reduce efficiency, and increase the friction, the heat and the fire risk. It’s a couple of the hidden costs of maintaining a vast network of infrastructure to collect low density energy. Coal turbines must be slowly rotated too, to avoid the shaft bending, but coal turbines run for months at a stretch without stopping. One coal turbine can weigh up to 600 tons, but wind turbines nacelles usually weigh 100-300 tons, but can weigh up to 700 tons)*. The largest wind turbine blades can weigh 35 tons each. The power-to-maintenance ratio of wind turbines is absurd.

There have been a lot of dead whales on the East Coast of the US lately. David Wojik noticed that NOAA was investigating 178 dead whales in something called an Unusual Mortality Event, or a UME — it’s like an episode of X-Files.
NOAA says this wave of strandings mysteriously started in 2016 which was before the offshore wind factory industry got going — but Wojik points out the timing matches very well. Offshore lease sales for the wind industry ramped up 2015-16. There were nine big sales, he says, off New Jersey, New York, Delaware and Massachusetts. And not so coincidentally, apparently 2016 was also the year that NOAA started giving permission slips for whale hunts, sorry whale harrassments for “geotechnical and site characterization surveys“.
In bureaucrat-valium-lingo, the license to cause incidental dead whales is called an IHA — or an Incidental Harassment Authorization. This appears to have fooled Greenpeace.
Although since wind turbines are a sacred totem, NOAA could have called them a 007 License to Kill Humpbacks and they might not have cared either. The whales are dying for […]
