The Renewable Age of Waste has arrived
How do you make a solar plant perform best at breakfast and dinner time — when humans need it most? Just build three times as much generation as you *need* and throw away most of what it produces in the middle of the day….
Solar panels peak at midday but demand for electricity is highest when everyone goes home and turns on the oven, the dryer and plugs in a Cybertruck. But that’s no problem when you have billions of taxpayer dollars to waste — just burn the money building generators that spend most of the day working at minimal efficiency. Then call that waste “Economic Curtailment” — supposedly because it not economically worth operating the equipment. This happens when wholesale prices have gone negative and solar plants are *choosing* to blow away the megawatts most of the day.
Profligate waste is not just a rare event but our national energy policy.
Looking at the graph below, “Availability” is what they could have produced on the left. But what they actually contributed to the country is shown on the right.

Engineers really don’t like phrases like “right skewed degradation with a long fat tail”
But new data suggests that’s exactly what’s is happening in the global solar fleet, and it’s bad news for insurers, installers, and grid planners.
One of the largest and longest studies ever done has looked at 11,000 solar panels around the world and found the same mysterious bump in unexpected failures. Surprisingly it didn’t matter whether the panels were installed in hot, cold or humid environments, the unexpected failures were still there. This suggests the higher failure rate is a systemic problem, not just something that afflicts those installed, say, in humid areas, or in the desert.
UNSW study finds up to 20% of solar panels degrade far faster than expected
By Casey McGuire Electrical Connection
Lead author Yang Tang says this has serious implications for system longevity: “Most solar systems are designed to last around 25 years, based on their warranty period.”
“But at least one in five systems degrade much faster than the typical rate and roughly one in 12 degrade twice as fast. This means some systems could lose about 45% of their […]
Solar Panels, Perth Australia

The government plays Santa Claus, but poor people paid for the “free” electricity a long time ago
It’s a very socialist solution to a socialist problem. Having screwed the free market, the government has to take desperate measures to limit the damage being done by the solar death spiral. The more solar panels we install, the more expensive electricity gets, which forces more people to install solar panels, etc and so on until “poof” we turn into Zimbabwe.
Last year, Jeff Dimery, the head of Alinta claimed that the “the rooftop solar glut” was so bad, the renewables transition itself had stalled. The solar surge in Australia has destroyed the profit margin for reliable generators. But it also killed the business case for new solar installations, and wind turbine parks too. With the national market bleeding negative prices at lunchtime, most generators would have to pay real money if they generate at lunchtime, but the household solar owners don’t. This created the perverse incentive where the only escape for households from rising electricity prices was to put solar panels on the roof. We’re reached the point where two thirds of […]
Nobody wants to say China
A couple of weeks ago at the Australian Clean Energy summit, there was a dawning realization that in our rush to diversify the energy grid we are accidentally “diversifying” our cyber security risks too.
Where, once upon a time, we could double and triple check the barriers around big old coal plants, now we have opened electronic doors to our grid on homes all over Australia. Energy geniuses told us solar panels would be decentralized, but instead, now that Australia has 25,000 megawatts of household solar, we have to add wireless gadgets to control them remotely. And some of these gadgets are coming in from fly-by-night small time operators. If, hypothetically, a foreign power wanted to be mean, or just hold an extra negotiating or blackmail card up its sleeve, we’re making it very easy. If Mr Chin wants something approved, he could say “Nice grid you have there…”
Small scale solar is so big, As Williamson points out, that it supplied 13% of the electricity to the NEM so far this year. And in Western Australia, it has generated 20%. (Boy is the West in trouble?)
On top of this, to deal with […]

The invisible shrinking solar industry
Quietly, the world manufacturing base for solar panels has been shrinking for nearly two years and yet hardly anyone knows. Especially not the Prime Minister of Australia who set up the the $1 billion Solar Sunshot a year ago to artificially create an Australian solar panel manufacturing industry, twenty years too late, and with the worst possible timing.
China has already captured the solar market and killed it.
Gluts have consequences
The CCP is making twice as many solar panels as the world wants to buy. The latest trend is from bad to worse.
Let’s remember this story, the next time the propaganda media try to tell us solar panels are setting new records. Isn’t this the sort of thing our investigative sleuths at the ABC-BBC-CBC should have been digging out before elections were held? Doesn’t this change everything?
Australia is supposed to be going gangbusters “leading the world” and installing 22,000 panels a day to meet our Net Zero target, but no one else in the world is doing that.

Nice grid you have there, shame if someone suddenly… switched it off
Two insiders at the US Dept of Energy say they have found covert devices inside solar panel inverters and batteries that would allow them to communicate with China. Even though firewalls have been put in place, these backdoor devices could operate around them.
Last August a Dutch white hat hacker got into 4 million panels in 150 countries in an effort to warn the West that major infrastructure was vulnerable. A month later an Australian cyber expert warned that a foreign hacker could turn our home batteries into “pager-bombs” too. If a hostile power turned off the overcharge protection on a sunny day, millions of solar panels would be pumping excess electricity into batteries that have no safety cut off. A few houses start to go off like popcorn, and an hour later we’re all living at the Western Front. How exactly would our firemen cope if 1 in 100 homes caught fire at the same time, and then we had a blackout? Anyone?
Individual solar panel inverters are generally too small to trigger national security […]

The latest news is that power has been restored in Spain, Portugal and parts of France, but the economic loss of a blackout that affected up to 55 million people for half a day is estimated at 2-4 billion Euro. Even Red Electrica, the Spanish Grid manager now says the initial event was a sudden power loss that was “likely solar”. And to top it off, the group that own the Spanish grid manager warned in February that with so many “renewables” the grid faced the risk of disconnections.
Meanwhile the billion-dollar-ABC is so far behind the times, on prime-time news tonight they were still saying the blackouts in Spain were a complete mystery — and did not mention renewables once, even though energy experts had warned this would happen for years, and were asking that question yesterday.
We are three days from an election and the ABC are running cover for the Labor-Greens party, and hiding from Australians that too many renewables and a lack of stable thermal or nuclear power plants were a front running cause. Even yesterday we knew that solar was supplying 60% of the Spanish grid, and that there was almost […]

Is this the Net Zero world we’re aiming for?
It could be a coincidence, but Spain’s grid ran entirely on renewables for the first time on April 16th. Less than two weeks later, at lunchtime Monday Spain and Portugal and even parts of France suffered massive cascading blackouts. Thirteen gigawatts of electricity, about half the grid, suddenly disappeared at 12:30pm. Trains were halted, and people were stuck in dark subway tunnels. A tennis tournament was stopped, flights were cancelled and diverted, and prosaically, as an emblem of the Western World, Spain’s nuclear plants shut too, and are now running on diesel back up. Shops have been stripped, people are fighting over taxis, and landlines and ATMs are down, and even the mobile network failed in Madrid. The mayor of Madrid has urged the PM to declare an emergency and deploy soldiers.
Electricity has been restored to some areas, but the grid operator has said “it could take up to a week to fix”. Other reports say “six to ten hours”.
Notably, Spain has one of the highest proportions of renewable power in Europe — with 50% of the national supply coming from pure unreliable power. Spain […]

In a brave election promise, the Australian Labor Party want poor people to help pay for batteries for rich Australians.
The discount battery deals will only be suitable for people wealthy enough to own a home with solar panels, and who happen to have ten thousand dollars sitting around that they don’t want to use or expect any return on for nearly a decade. There can’t be too many of those.
The true cost of home batteries is about $13,000, so the $4,000 discount still leaves a big bill. And the savings for electricity bills are estimated to be around $1,100 per household each year. So no one comes out ahead for nine or ten years, and that’s assuming their battery is still useful at age ten or eleven, and their house hasn’t caught fire.
This policy isn’t a winner for the rich or the poor. Because batteries are essentially uneconomic, the policy screws the whole country. The only beneficiaries are the solar and battery installers and Chinese industrialists. Them, and the politicians who got us into this mess. To avoid admitting they were wrong, they’d probably like to trick Australians into buying the batteries that […]

While careers and statues have died at the merest hint of not refuting slavery hard enough, the UK Labour Party will make sure slave-made-solar panels will still be imported to the UK, and the people exploiting the slaves will still be paid.
We have to ask, O’ Great Moral Guardians, was it because there aren’t enough solar panels that are not slave-made, and if we stop supporting the slavers, the only panels left will cost a fortune? Is the big fear that it will blow the climate budget, or make green electricity even more absurdly expensive?
Or are we saying that the lives of slaves in 2025 are not as important as cooling the world by 0.0001 degrees 100 years from now?

His words are about as blunt as any hedge fund owner could possibly get.
Hedge Fund Built on Energy Bets Says ‘Clean Is Dead for Now’
Bloomberg
“The whole sector — solar, wind, hydrogen, fuel cells — anything clean is dead for now,” said Nishant Gupta, founder and chief investment officer at London-based Kanou Capital LLP.
Against a barrage of political headwinds in the US, a war-fueled energy crisis and stubbornly high interest rates, large parts of the clean-energy industry are stalling. In the past year, the S&P Global Clean Energy Index has lost 20%, a period during which the S&P 500 Index gained 16%. And with the Trump administration shredding climate policies in the world’s largest economy, many green investors are taking a timeout.
Over the last year clean energy stocks have lost 20% of their value, whereas stocks in fossil fuels are up 13%.
So after the last year, skeptical investors are 30% richer than their believer friends. As it should be.

Without forced theft from the poor, Sunnova (and others in the solar industry) might disappear
Bloomberg writers call it “chaos” and Barrons blames Trump for “uncertainty”, but the truth is the value of solar was always a false bubble held up by forced payments, fantasy, or vicarious political whimsy that spread the costs onto other people. Trump has merely restored the certainty of real value in the free market. He hasn’t banned a single person from buying solar panels, it’s just that not many people want to spend their money on glass panels that make green expensive electrons. They don’t want to spend money on “cheap electricity” that only comes at lunchtime either.
The 70% fall in the stock price is just the last few days since Sunnova officially warned it might not be a “going concern”. The longer term figures are much worse.
On November 4th, when some investors though the word-salad-woman might win, the share price briefly spiked to $7. Right now it is 58 cents, meaning it has lost 92 percent of its value since Trump won the election. The entire $12 mini-boom peak in September last year, arguably, was a bet that […]
Post-modern temples to the Sun God

It was supposed to last 50 years…
The PR writers want us to believe the legendary Ivanpah has been beaten out by better cheap solar, and that this is somehow a “success”. But the truth is, it’s been killed by the same subsidies and crooked market that birthed it.
The Big Government Blob distorted the free market, and created a boom in solar power. But the business case was not that good, there was no miracle in the storage of electricity, nobody wanted fried birds, and the subsidies kept forcing more solar power generation in at the same useless time of day.
Since there were too many generators at lunchtime and not enough customers, the last surviving part of the free market has solved the imbalance.
Just another artificial boom and bust
In 2014, the project cost $2.2 billion dollars. Ivanpah has 173.000 heliostats, and theoretically could make 390 megawatts in a perfect moment. But no one in their right mind would have spent so much to get so little, so the government spent $1.6 billion taxpayer dollars as a “loan guarantee”.
I wonder how that is working out […]

Here in crazy Australia, we have too many renewables, but both sides of politics still want more
Here in the Renewable Crash Test Dummy Land, both sides of politics think we should use our national grid for weather control which is good for President Xi, but bad for Australians. The Opposition is pointing out that the 82% renewable purity target is bonkers, and we should add nuclear plants, while the Labor party are hell-bent on running the world’s first experiment in wind and solar with not much hydro, no nuclear power and no extension cords to a international market that can rescue us. Literally no nation on Earth is this recklessly ambitious.
With an election coming, and domestic electricity prices approaching escape velocity, both sides are sparring with economic reports. The government claims it can do a national wind and solar miracle grid for just $122 billion. But Frontier Economics put the cost at $594 billion. The opposition, meanwhile, has finally revealed the first serious costing of their big new nuclear power plan is $331 billion (which is $260 billion cheaper), but it’s still $300 billion we don’t really have.
Awkwardly for Labor, both […]

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.

It’s grand final day in Australia, and awkwardly the State of Victoria risks a grid overload. A truckload of solar power will arrive at lunchtime that no one needs, and which has no place to go.
The largest single generator in Australia now is rooftop solar and it’s virtually uncontrollable. The geniuses running the national grid have subsidized solar panels and made electricity unaffordable at the same time, thus driving more householders into the arms of the solar industry.
So they’ve created an artificial market bubble — as all good communists do. We now have a 20 gigawatt capacity generator that mostly can’t be turned off, except by clouds or possibly Chinese cyberwarfare.
And where autumn and spring used to be the easy seasons, now Sunny spring days are diabolical too — hardly anyone needs their air conditioner or their heater at lunchtime, but solar watts are pouring in.
This was the situation yesterday in Victoria:

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 […]

If the Germans just did nothing at all, it would have been Greener
Germany already had nuclear power in 2002, if they just kept it and didn’t build all the wind and solar plants, they wouldn’t have had to spend 697 Billion Euro on subsidies, and would have cut their emissions by 73% more.
If ever there is a statistic that says there is something rotten in the State of Climate Panic, this is surely it. I mean, does CO2 matter or doesn’t it? Do the Greens care at all, or even a bit? If there was a climate emergency and The Greens were worried about CO2, they might have protested that the EnergieWende was a reckless experiment. But if the Greens were tools for communists, foreign states or banker-investors, then they might keep choosing options that benefit other countries, help Bankers or just make Big Government bigger.
Either the German Greens have utterly failed at the very task they set out to do, or they were really aiming at something else.

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…
