How often do you clean your solar panels? Spare a thought for the poor sods in the Middle East, India and China, where migratory dust coats solar panels and hangs around in the air, blocking incoming sunlight. Researchers in India who cleaned their panels every few weeks and discovered that they got a 50% jump in efficiency each time. If the cleanings happened every two months, the total losses were 25 to 35 percent.
The article very much blames human pollution for half the capacity loss, but in the detail, the press release admits that 92% of the dust on each panel was natural. Apparently human made particles are smaller and stickier which makes the 8% human-emitted-dust equivalent to the 92% of other dust.
Either way, real pollution and natural dust will slow the clean-green-energy future in India and China until we get auto-cleaning panels or roof slaves. Unfortunately, cleaning panels also risks damaging them, so the price of solar power really needs to include the cost of windscreen-wipers/slaves, electricity losses, damage to panels, and damage to the panel cleaners too.
But solar panels will definitely power all the other parts of the world that are near enough to the […]
Another award winning solar project collapses: it was a $105 million dollar scheme. One company, Areva, lost about $50m and so did the taxpayer. Everything went wrong, management, planning, cheap poor quality steel from China, industrial dispute that left 80% of the pipes rusting on a dock. Three thousand solar reflectors are sitting unused in what was a potato paddock in Dalby. Nobody wants to buy them. They’re obviously worthless. CS Energy is state owned power utility, and it spent $50m but pulled to pin to save wasting another $50m.
In 2011 Julia Gillard raved about how it was going to save 35,000 tons of carbon.
“Ms Gillard says the project could be one of many under the new carbon tax scheme.
“With the clean-energy future I want for our nation, I want it to be a norm,” she said.”
Fans of renewables will cite the management problems as the reason for the failure, not some inherent problem with solar. But the “Clean Energy Culture” is the problem — the same pathetic, uninformed and corrupt decision-making that subsidizes solar so unnecessarily also creates the same dud decisions in management, legal, and industrial relations. The environment […]
There are probably more solar panels in QLD than anywhere else in the world. Back in February last year, the boss of the Queensland state power company announced the awkward result that households with solar panels were using more electricity than those without. Apparently people without solar were turning off the air conditioner because electricity cost too much, but the solar users didn’t have to worry about the cost so much.
Queensland solar homes are using more grid electricity than non-solar, says Energex boss
Feb 2016: Solar-powered homes in south-east Queensland, which boasts the world’s highest concentration of rooftop panels, have begun consuming on average more electricity from the grid than those without solar, the network operator has found.
Terry Effeney, the chief executive of state-owned power distributor Energex, said the trend – which belied the “green agenda” presumed to drive those customers – was among the challenges facing a region that nevertheless stood the best chance globally of making solar the cornerstone of its electricity network.
From October 2014 in Queensland, the average grid electricity use of solar homes started to exceed the average use of people without solar power and stayed higher for the […]
It takes bumper government subsidies to destroy this many trees for so little reason:
Six Flags Adventure Park goes Solar — Slate
The plan, the largest solar installation in New Jersey, will generate 21.4 megawatts of electricity, enough to power the amusement park’s Garden State facility. The company projects that the initiative will eliminate approximately 215,000 tons of CO2 emissions over 15 years…
“We are excited about the fact that this project will reduce carbon emissions by 31 times more than the trees and shrubs that will be removed, and that we will become the world’s first solar-powered theme park,” said Kristin Siebeneicher, communications manager for Six Flags Great Adventure and Safari.
The 66 acres of native wildlife may not be so excited.
Nor are the surrounding hominids. Can’t please em’:
Local residents and environmental groups—including Clean Water Action, Crosswicks/Doctors Creek Watershed Association, Environment New Jersey, NJ Conservation Foundation, Save Barnegat Bay, and the Sierra Club—beg to differ, claiming that razing nearly 15,000 trees will adversely impact water quality, air quality and sound quality; decrease the wildlife population; and affect biodiversity,…

If only solar generation was affordable?
In Nevada there is a lot of sunlight and a lot of solar panels, but they generate electricity at a cost of 25 – 30c per kWhr. With subsidies and tax benefits, the cost “falls” to 15c. (In this context, the word “falls” means “is dropped on other people”.) But the retail rate for electricity is 12.5c. So having solar panels doesn’t help you much unless you can sell that excess electricity, which the state of Nevada was buying at 12.5c. That price sounds fine and dandy til we find out that they could have bought the same electricity at wholesale rate of around two cents.
So Nevada has decided that’s what the state will pay… 2c, not 12.5c. The latest decision is to apply normal free market rules. Nevada will now pay wholesale rates for electricity. No more shopping for boutique electrons.
Taking into account all the tax cuts, subsidies and total costs, who would have thought that paying 15 times the wholesale rate for electricity would be economically unsustainable?

Remember, all developed countries are going Green, and Clean Energy is everywhere. It’s only (insert your country) that is falling behind.
When you hear this, think of Spain. It is so green it’s just passed a tax on solar panel generation, so solar users finally pay for grid backup. This Spanish government has been building a renewable future with so much enthusiasm that their wind industry is described as “striken” and it’s estimated that the current government there has cost “65,000 green jobs”.*
That solar tax:
“The tax will be introduced in the next six months, according to a statement from the Ministry of Industry, Energy, and Tourism. It will apply to solar power systems with a capacity of over 10 kilowatts.
The Ministry said the tax is intended to ensure that solar panel users contribute to the cost of maintaining the country’s electrical grid, as they use it as a backup supply. “
They’ve been trying to get this tax through for a long time. It’s described as unpopular by the usual suspects and, improbably, as a tax on the “Sun” (but will the sun pay, I wonder?). Supposedly, I imagine, the indignation […]
Renewable power is always as “cheap as coal” except when subsidies are slashed, then it’s “the end”, “terrible”, and “fragile”.
If only renewable power could actually compete with coal.
Greenclick tells us the UK solar industry is “reeling” in “shock and anger” as the UK conservative government cuts the renewables feed-in tariff there by as much as 86%. Even for the hydro industry (about the only renewable industry that can survive on its own), the news could spell the “end”.
Joss Blamire, Senior Policy Manager at Scottish Renewables, which represents more than 300 green energy businesses, said: “The proposals in the Comprehensive Feed-in Tariff Review are, quite simply, terrible news for homeowners, businesses, communities and those local authorities which have plans in place to develop renewable energy schemes.
“The levels of reduction in support announced today will severely curtail development of small-scale onshore wind and solar projects and endanger jobs and investments across the country.
“The cuts could also spell the end for much of the hydro industry, which has enjoyed a recent renaissance but relies more heavily on Government support because of the length of time taken to develop projects and the sector’s […]
Oops. Who hates “the environment”? Green lobbyists keep revealing how little they care. Friends of the Earth want to categorically rule out one of the most cost effective ways to reduce our carbon emissions. New supercritical hot burning coal plants can reduce emissions by an amazing 15%. But Friends of the Earth and The Guardian hate coal more than they care about CO2.
The green climate fund (GCF) refused an explicit ban on fossil fuel projects at the contentious meeting in Songdo, South Korea, last week.
“It’s like a torture convention that doesn’t forbid torture,” said Karen Orenstein, a campaigner for Friends of the Earth US who was at the meeting. “Honestly it should be a no-brainer at this point.” — The Guardian
Poor old solar and wind power are so useless that the debate is about whether they achieve any reductions at all. Their intermittent power means some kind of back-up base load power source has to run on standby to pick up the pieces when they collapse. The more wind power you have, the less CO2 you save. Solar Power provides “cheaper” electricity to the rich at the expense of everyone else, and potentially […]
A new report shows ABC journalists are fond of renewables and overlook their dismal economic value, while putting out bad news on coal, and ignoring the benefits of vast cheap profitable energy. Who could have seen that coming: a large public funded institution attracts employees who like large public funding?
The IPA arranged for a media analysis firm to compare the ABC reporting on coal and renewables.
ABC gives the green light to renewables, and the red light to Australia’s largest export industry and provider of 75% of our electricity.
ABC accused of bias against coalmining
Andrew Fraser, The Australian
The analysis of 2359 reports broadcast on the ABC over six months before March 15 this year found 15.9 per cent of stories on coalmining and 12.1 per cent of those about coal-seam gas mining were favourable, while 53 per cent of those on renewable energy were favourable.
It also found 31.6 per cent of stories on coal mining and 43.6 per cent of stories on coal-seam gas were unfavourable, while only 10.8 per cent of stories on renewable energy were unfavourable.
The ABC has become its own best case for privatizing the ABC. How much could we get? […]
A little too much solar success perhaps?
Solar panels in Queensland and NSW in Australia have been providing some householders with energy in a more concentrated form than they bargained for. At least 70 houses with rooftop solar panel arrays have had solar driven burnouts. The fire risk means that nearly 30,000 faulty solar power isolators have been recalled. The company that imported them went bust on Friday. (Ain’t that the way?)
Remember if your house burns down, it is the price we pay to save the planet. It will, unfortunately, blow your personal carbon footprint through the roof. (A point that will, no doubt, grieve you as you sift through the smouldering ruins.)

Announcing the all new Solar-Insolation Hiroshima Bomb App, thanks to Dale Kent.
Since 1998, Global Warming has been occurring at 4 Hiroshima Bombs per second, not that we can measure that rate to a statistically significant value*, or that it means anything at all. Every second the sun pours 2700 Hiroshima bombs of energy on the Earth at the top of the atmosphere.
As well as missing the big-picture, Cook and Nuccitelli show us they don’t have a good grip on cause and effect. The world may have been warming, but that does not mean that CO2 caused it. Though they would very much like you to think that.
But if you want to scare people out of their money and impress fools, the Skeptical Science widget is just the thing. As SkS say on their page: “ Put a widget on your blog to let people know that climate change is important to you. ” To which JoNova adds, “The Sks widget performs a valuable service, advertising the bloggers who don’t understand big numbers or trends, and who struggle with statistical significance. If someone wants to show they think-with-the-herd, and not with their brain, the SkepticalScience widget […]

US citizens pay for “solar school” foolishness
By Steve Goreham
Originally published in The Washington Times
Solar systems are being installed at hundreds of schools across the United States. Educators use solar panels to teach students about the “miracle” of energy sourced from the sun. But a closer look at these projects shows poor economics and a big bill for citizens.
Earlier this month, the National Resources Defense Fund (NRDC) launched its “Solar Schools” campaign, an effort to raise $54,000 to help “three to five to-be-determined schools move forward with solar rooftop projects.” The NRDC wants to “help every school in the country go solar.” The campaign uses a cute video featuring kids talking about how we’re “polluting the Earth with gas and coal” and how we can save the planet with solar.

Is this a 2013 Streisand-Effect finalist?
The UK has decided to build its first new nuclear power plant in 20 years. The UK Department of Energy & Climate Change posted this graphic below in a News Story probably to help justify why it really did make sense to go nuclear rather than renewable. The Renewable Energy Association called it “unhelpful”, and lo, it disappeared from gov.uk.
Credit goes to Emily Gosden’s Tweet, and Will Heaven‘s Blog. Hat tip to Colin.
(Click to enlarge to see the fine print)
The fine print (edited out in the small copy here) says that Hickley Point C “is estimated to be equal to around 7% of UK electricity consumption in 2025 and enough to power nearly 6 million homes.” About onshore wind, the fine print reads: “The footprint will depend on the location and turbine technology deployed. DECC estimates the footprint could be between 160,000 and 490,000 acres“. That’s quite some error margin.
How many National Parks does one nuclear plant save then?
It’s a good representation of just how much of the Earths surface we have to give up if we want to live off renewables at the moment. So who […]
How is the hallowed Green tech industry working out for China? Not so well.
Shi Zhengrong was called a “hero of the environment” by Time Magazine. He was a billionaire who ran the worlds largest seller of solar PV cells. But the glory days of 2008 – 2011 are gone. Another bubble bursts. Wiped out in two years. How fast was this fall?
Chinese solar panel maker Suntech flames out
By Steven Mufson, Published: May 3 The Washington Post,
In 2008, CNN named Shi “China’s Sunshine Boy.” In 2009, Fortune anointed him “China’s new king of solar.” That year, New York Times columnist Thomas Friedman also cited Shi and Suntech as models of China’s green leap forward — which he called “the Sputnik of our day” and a spur for U.S. clean energy policy.
Now, however, the Chinese Sputnik has crashed to Earth, and the Sun King has been toppled.
… a Chinese court declared the company bankrupt after a petition from eight Chinese banks. On Wednesday, the company announced that its 2012 revenue had plunged 48 percent from the previous year.
Suntech — which in 2011 was the […]

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.

Only five years ago Australia had a mere 20,000 solar systems installed on homes across the country. Now thanks to a Gonzo-Big-Daddy-Government we have over one million solar systems, almost all of them producing electricity that could have been made for something like a fifth of the price with coal.
The Clean Energy Regulator spins it as though wasting money on inefficient equipment in the hope of reducing world temperatures is a good thing for Australia.
“…the Clean Energy Regulator, which estimates that those solar energy systems provide power for around 2.5 million Australians. With a population of around 23 million, that means over ten percent of the country benefits from solar power.”
So 10% of Australians benefit from solar, and 90% pay for it?
“The regulator also says the installations have saved Australians about half a billion dollars on electricity bills!”
The regulator doesn’t say how much Australians had to pay to “save” a half a billion dollars.
In Dec 2011 The Productivity Commission estimated $777m in one year alone:
At the prevailing REC prices, this effectively provided an up-front capital subsidy of $777 million to solar PV systems in 2010.

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?

For forty years, people have tried to get Solar to work. Now, the worst possible thing for the industry has occurred: The Left are serious about trying to help it.
The Large-Scale Solar Subsidies are bountifully generous on an unprecedented scale that involves taxing everything else that moves, but even that generosity is not enough to compete with…wait for it… the even more insanely lavish Small-Scale Solar Subsidies. Who would have thought? Remember these are the same people who tell us that the “free market solution is best”. They offered three times the going rate for rooftop solar electricity, and through utterly predictable market mechanics, created a glut in rooftop solar panels as every man and his dog rushed in to get free electrons from their roofs, and on good sunny days, even cheques in the mail. Now, the large-scale projects are struggling to get major electricity retailers to sign long-term contracts.
THE federal government has delayed issuing key grants under its $1.5 billion Solar Flagships program after a preferred applicant, the Moree Solar Farm, failed to meet a December 15 deadline to reach financial closure on its project.
Solar projects have struggled to secure contracts with retailers, who […]
