It’s just another day of profligate waste in Renewable World
It’s barely spring in Australia and already we’re reaching the point where there’s too much solar. There’s such an excess of useless energy, prices are negative, meaning the hapless generators have to pay people to take the poison power away. And on Sunday, at a time when investors ought be making their peak profit for the day, they were rushing to turn 80% of their panels off.
Feel the pain — the stunted curve of the solar plants (below) is supposed to be the same shape as the rooftop PV.
In reality, this is how we make the parabolic curve of orbital solar physics fit a rectangular box — by building five times as much as we need and wasting most of it.
Anero.id
Bear in mind, this is just the start of a the lumpy road to nowhere. Even though we already have more solar panels than we can use, we’re supposed to be installing 22,000 more panels every day in Australia to reach our mystical NetZero target.
Paul McArdle of WattClarity noticed the dire situation. As he says “rooftop PV is killing […]
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 […]
ENI Katherine — might as well be a pagan temple to the Sun.

The Northern Territory is a test case for renewable energy and it’s a bonfire
In 2016, the new Labor Government waved a magic wand and commanded they would be 50% renewable by 2030. The experts said it was doable and would save $30 million a year. They gave out the permits for large solar installations, which began construction in 2019, but then suddenly changed the rules in 2020, and wouldn’t let the solar plants connect to the main Darwin-Katherine grid. Unbelievably, 64 megawatts of solar panels that cost $40 million dollars have sat, doing nothing, for four long years.
“It’s just reflecting back into space, not being used to power the grid and to substitute for diesel and gas turbine production,” said local vet Peter Trembath, who leased his land to energy company Eni Australia for the solar project.
“It’ll be some technical issue, but you’d reckon they would have sorted that out before Eni spent $40 million to erect it.” — Max Rowley, ABC News June 2022

What if a few gigawatts of solar power disappeared without a warning or a cloud in the sky?
Imagine a hostile force had control of half your national power generation at lunchtime and could just flip a switch to bring you to your knees? Or how about a crime syndicate wanting a ransom paid by 5pm?
Steve Milloy: Communist China is setting us up for solar panel-based disaster:
“Solar panels that make the electricity suitable for the power grid and which are usually connected to the web, can be “easily hacked, remotely disabled or used for DDoS [Distributed Denial of Service] attacks.” DDoS is one of the most common types of attacks, which basically try to overwhelm a system… Solar panels were outlined as a vulnerability in several scenarios, also due to the dominance of a single country, China, in the supply chain.”
It’s only a week without electricity…
Daniel Croft, CyberDaily (October 2023)
Cyber Security CRC chief executive Rachael Falk said… that an attack on the solar grid could spark a “black start” event, which could result in the entire power grid going down. … “This […]

Hiding the costs of renewables until after the next election
The largest coal plant in Australia was supposed to close in August next year, but the NSW government decided to buy a two year extension until a few months after the next state election. Now the modeling comes out showing that they decided to keep the Eraring coal plant running to prevent the shocking price spikes from disturbing the voters. Keeping the coal plant will reduce wholesale electricity bills by a few billion dollars. (Why don’t we keep it open for ten years?)
Presumably his reelection chances would be worse if “saved the planet”, and shut the coal plant a few months before the election instead.
They know the voters don’t want the transition. They know it will cost more. And yet they do it anyway…
Bizarrely, this news comes from the renewable industry site Reneweconomy, where Giles Parkinson doesn’t seem to notice this shows coal power is cheap and renewables are hideous. Apparently he doesn’t mind inflicting costs on hapless homeowners, he is just bummed that they couldn’t force more unreliable energy and battery packs on the grid even sooner:

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

They want you in an EV so they can use your battery to rescue the unreliable grid they built
There is a desperate need to add billions of dollars worth of batteries to smooth out our volatile grids. As I said last year:
The hapless homeowners will buy the back up battery for the grid and install it in their garage. (Sometimes they might drive it too.)
It’s so much the better if the unwashed masses pay for the batteries themselves, and so it has come to pass. Some academics in Canberra are excited that they finally proved the point and sucked some electricity out of 16 cars at a tight moment in February.
A vehicle-to-grid response: Electric vehicles fed power into Australian grid during blackout, says report
During a major storm event that eventually cut power to tens of thousands of homes, a fleet of electric vehicles (EVs) were able to feed power back into Australia’s electricity grid, according to a new report from The Australian National University (ANU).
These 16 cars provided all of 107 kilowatts for an unspecified length of time.

The real cost of back up
Imagine building and maintaining a perfectly good gas plant and then having it sit around for five whole years “just in case”?
There’s been a wind drought in the last three months in Australia, which meant hydro power had been used more than expected to fill the gap. But wouldn’t you know it, it’s been dry spell for most of the last year in Tasmania too and the dams were getting low. So on June 6th, the Combined Cycle Gas plant at Tamar Valley was set up to run for the first time since 2019.
Back in 2016 the maintenance costs of the keeping the CCGT at Tamar Valley on “30 day” standby was $12 to $24 million a year, depending on who you asked. So the five year cost of gas backup is in the order of $100 million, but those costs will be slapped on the gas plant bill, when really they’re a weather dependent renewables cost. What we need is reliable energy, not random electricity. If energy companies were only paid for reliable dispatchable power, the wind and solar plants would have to build their own “back up […]

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 […]

Global fossil fuel use hits a new record level in 2023
We spent $1.77 Trillion dollars on the clean energy transition last year, yet our fossil fuel use is still rising and our emissions are still increasing.
The Energy Institute released their annual “Statistical Review of World Energy”. Total energy used in the world went up by 2% showing no sign of slowing down. For the first time, more coal was used in India than Europe and North America combined, a trend that is unlikely to stop soon. Despite there being more EVs on Earth than ever before, oil consumption was up 2% to above 100 million barrels for the first time. China overtook the US as the country with the largest oil refining capacity in the world last year at 18.5 million bpd. But the US overtook Qatar as the largest exporter of LNG. And global man-made emissions of carbon dioxide exceeded 40 gigatons for the first time.
Imagine what a different place the world would be if we spent that money on something useful? Just a tenth of that might provide clean water and sanitation for the poorest of the poor and stop children […]

The Renewable Crash Test Dummy hits a fork in the road
Finally the Australian opposition is bravely popping the sacred cow of the Energy Wars. The Dummy nation was aiming for the holy grail “low emission” grid that no other nation had tried. The driest continent on Earth, with small hydro, and no extension cords to any nuclear power, were going to build the perfect grid based on the wind and sun alone. It was always doomed to fail, it was just a question of how much money would be burned at the pyre before the Crash Test Dummy crashed.
Because they didn’t do their homework, and the fan-media didn’t ask them to, the Labor Party set themselves up to fail. They left their left flank wide open, and the Opposition is finally launching the missiles that have been there all along in the mist. The ultimate low-emissions generator was always and obviously the unspeakable nuclear power. It’s a fifty year old technology. If anyone actually cared about carbon dioxide, they would have done this instead of the Kyoto scheme in 1997. But it was all a theater of grift and graft for unreliable, fairy energy, […]

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 […]

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…

About 90% of solar panels installed in Germany come from China, and earlier this year one of the last solar panel manufacturers closed in Germany. Last week, what was left of the industry begged for mercy (and subsidies) which they didn’t get. Now another German solar panel manufacturer has closed down.
For some cruel reason German factories which are close to their customers, can’t compete with distant foreign factories which have access to slave labor, fossil fueled shipping and cheap coal fired electricity?
The bigger question, seemingly, is how did the country that invented the printing press, diesel engines, and the theory-of-relativity get fooled by such a stupid ploy? Someone told them they could save the world with unreliable energy, so they converted their generators to unreliable ones, only to discover that they can’t afford to use unreliable generators to make the unreliable generators they need to keep saving the world?
The only government stupider than Germany is the one that has already seen how badly this worked out and announces they’re going to do the same thing. Australia is not only ten years too late, but China has flooded the market to the […]
Solar panels eat the profits of the reliable generators for lunch

The system is reaching a crisis point and April is turning out to be the month of confessions
His speech was the sound of an industry being tortured. The transition is going backwards. Big projects are stalled. Costs are rising and reliable old assets are being closed too quickly. It’s like we are disassembling the plane as we fly it…
A couple of weeks ago in Australia the chief of Alinta Energy admitted in a big speech that the industry needs to be honest with the public about the costs of the transition. This marks a big shift from the “cheaper and cleaner” misinformation which the renewables industry was practically built on. Jeff Dimery had a stark warning — his company bought a large old coal plant in Victoria for a billion dollars in 2018, and it powers one fifth of Victoria. But to replace that today with renewables would cost $10 billion.
But he also laid bare the crushing effect subsidized rooftop solar PV panels are having on the transition. No news outlets seemed to appreciate the implications of this. Fully one in […]

In the Bermuda Triangle of electricity bills, the more cheap generators you add, the higher your electricity bills grow
The experts at the CSIRO tell us that renewables are the cheapest sources of electricity, with all their Capex calculations and their levelised maths, and yet the electricity bills set the house on fire. (It’s Russia’s fault!) Could it be that the experts accidentally forgot to analyze the system cost and that all the hourly megawatt dollars per machine don’t mean a thing?
In the race to the most expensive electricity in the world, this week the UK is the winner. Germany is handicapped by being bundled into the EU27, lumbered with all the French nukes and is therefore not in the running. Australia is missing in action, but possibly only because the price rises were too fast and too much for the Eurostat, the US DoE, and IEA to keep up with, so they gave up.
And people wonder why China is the world’s manufacturing base.
A European Commission study:
In the next graph is the “rest of the world”. After 2021 Australian electricity prices are unmarked for some reason, but officially they rose 20% two […]

It’s just another signpost on the way to the Great Green Economy Downunder
We’re watching the renewable bubble pop around us. Tritium was the wonder-child Australian technology business that built fast chargers for electric vehicles. It took 20 years to create, and only two years to unravel into receivership. At its peak in 2021, it launched on the NASDAQ and was worth $2 billion, now it is insolvent.
The Driven, explains just how big it was:
The company says it has sold more than 13,000 DC fast chargers in more than 40 countries. At its peak it claimed to be the biggest maker of fast chargers in the US with a 30 per cent market share (unclear if this included the Tesla network), and a 75 per cent share in Australia, and one of the top three in Europe.
When it launched in 2021, shares were selling for $2,500 each. The current price is $1.35.

By Jo Nova California was the Land of Solar Panels at the top of the Magic Subsidy Tree but that boom went bust
If solar panels were actually cheap and useful, everyone could have them, they’d pay for themselves, and there would be no point where the panel-party would grind to a halt. But if they were expensive, made something useless, and their product became toxic to the grid itself the government would have to artificially subsidize them to get them onto the grid in the first place, and then pop its own bubble before the bubble popped the grid. And so that time has arrived in California and there is carnage in the market.
The Duck has quacked
In a strange coincidence the Californian government cut the payments for solar-powered-electricity by 75% last year, and sales of solar panels fell to a quarter of what they were a year ago. That’s a “to” not a “by”. One in five solar contractors has already left the market. Careers and businesses — gone.
The new price for solar-powered-electricity is probably slightly closer to the true market value, which is almost zero, or even less for holy-green electricity at noon. The Duck […]
