The Global Warming Policy Forum has condemned what it called the “obscenity” of windfarm subsidies and has called for a complete rethink of energy policy.

GWPF research has shown that just six offshore windfarms are now sharing £1.6 billion pounds in subsidies between them every year.

Three receive annual subsidies of over a quarter of a billion pounds each year.

Climate virtue signallers demand belief in their fool’s paradise, regardless of cost.

PA Pundits - International

By Ronald Stein ~

With many still living with little to no access to electricity, American politicians are pursuing the most expensive ways to generate intermittent electricity with offshore wind turbines on the East and West Coasts.

The U.S Energy Information Administration (EIA) has already documented that offshore wind continues to be one of the most expensive forms of electricity generation.

Energy poverty is among the most crippling but least talked-about crises of the 21st century. Electricity is the one of the simplest solutions to improved health, economic opportunity, education, nutrition, and comfort in the developing world, especially for women and girls.

In the world’s poorest countries, there are 11 million children in the world dying every year.

Those fatalities are from the preventable causes of diarrhea, malaria, neonatal infection, pneumonia, preterm delivery, or lack of oxygen at birth as many developing countries have no…

Wind and solar power’s hopeless intermittency has forced rent seekers to engineer yet another fraud: hydrogen gas – which is to be purportedly produced using wind and solar’s occasional and chaotic output. Where wind and solar have never made any sense, the hydrogen proposition is completely bonkers.

Defying the laws of physics and thermodynamics – just for starters – the economics would make hydrogen gas produced using already heavily subsidised wind and solar the most expensive energy in human history.

And yet, the same class of dimwitted politicians are signing up in feverish earnest, as if they’re about to back a surefire Melbourne Cup winner.

As with wind and solar power, it’s the same too-good-to-be-true pitch directed at the starry-eyed, gullible and naïve. All, of course, in the name of obtaining a stream of taxpayer back subsidies that will outlast religion.

Starting this week, Sky News will get deadly serious in its coverage of climate change by highlighting every night the time we have left until the planet overheats, says I-news.

The figure is already less than 12 years, and the on-screen ticker will be counting down, second by second, as we head towards the ominous limit of 1.5°C hotter than when the Earth’s temperature was first comprehensively measured in 1880.

That ceiling was set in Paris at COP21, the 2015 UN Climate Change Conference, and Sky News has made its bold statement as we approach COP26 in Glasgow in November.

The ticking clock, built by Concordia University in Canada, will feature on a giant dashboard that will be a permanent studio fixture on The Daily Climate Show, which begins on 7 April as the UK’s first prime-time news show dedicated to the environment crisis.

Just One Number Keeps the Lights On

There’s going to be a lot more ‘demand management’ aka use of price variation, deals with industrial users, and other tools to lower peak demand when it threatens to get too high for a renewables-oriented system to handle. Whether that will always work is anyone’s guess, but seems unlikely due to cost if nothing else.

David Wojick explains how maintaining electricity supply is simple in his CFACT article It takes big energy to back up wind and solar.  Excerpts in italics with my bolds. (H/T John Ray)

Power system design can be extremely complex but there is one simple number that is painfully obvious. At least it is painful to the advocates of wind and solar power, which may be why we never hear about it. It is a big, bad number.

To my knowledge this big number has no name, but it should. Let’s call it the “minimum backup requirement” for wind and solar, or MBR. The minimum backup requirement is how much generating capacity a system must have to reliably produce power when wind and solar don’t.

For most places the magnitude of MBR is very simple. It is all of the juice needed on the hottest or coldest low wind…

A model for California? [image credit: Hitesh vip @ Wikipedia]


Worth asking what is meant by ‘could be economically feasible’ in this context. Running power stations 24/7 looks a lot simpler than having thousands of miles of solar panels to install and maintain, which sit idle without sunlight.
– – –
UC Santa Cruz researchers published a new study—in collaboration with UC Water and the Sierra Nevada Research Institute at UC Merced—that suggests covering California’s 6,350 km network of public water delivery canals with solar panels could be an economically feasible means of advancing both renewable energy and water conservation.

The concept of “solar canals” has been gaining momentum around the world as climate change increases the risk of drought in many regions, claims TechXplore.

Solar panels can shade canals to help prevent water loss through evaporation, and some types of solar panels also work better over canals, because the cooler environment keeps them from overheating.

Pilot projects in India have demonstrated the technical feasibility of several designs, but none have yet been deployed at scale.

California’s canal network is the world’s largest water conveyance system, and the state faces both a drought-prone future [Talkshop comment: evidence-free assertion] and a rapid timeline for transitioning to renewable energy.

Solar canals could target both challenges, but making the case for their implementation in California requires first quantifying the potential benefits. So that’s exactly what researchers set out to do in their paper published by Nature Sustainability.

“While it makes sense to cover canals with solar panels because renewable energy and water conservation is a win-win, the devil is in the details,” said Brandi McKuin, lead author of the new study and a UC Santa Cruz postdoctoral researcher in environmental studies. “A critical question was whether the infrastructure to span the canals would be cost-prohibitive.”

Canal-spanning solar panels are often supported either by steel trusses or suspension cables, both of which are more expensive to build than traditional support structures for ground-mounted solar panels.

But McKuin led a techno-economic analysis that showed how the benefits of solar canals combine to outweigh the added costs for cable-supported installations. In fact, cable-supported solar canals showed a 20-50 percent higher net present value, indicating greater financial return on investment.

In addition to benefits like increased solar panel performance and evaporation savings, shade from solar panels could help control the growth of aquatic weeds, which are a costly canal maintenance issue. Placing solar panels over existing canal sites could also avoid costs associated with land use.

Now that the new paper has provided a more concrete assessment of these benefits, members of the research team hope this could lead to future field experiments with solar canals in California.

Germany’s main gas supplier: Russia


Countries like Germany must know that once all their nuclear and coal plants have been closed (by order), their security of electricity supply would be heading towards zero without gas and imports. Saying it’s just a question of peak demand is nonsense, and they know that as well, but still pursue their delusional energy policies. What happens after 2050 when the gas is turned off is a mystery.
– – –
The European Commission is reconsidering the position of gas in its sustainable finance taxonomy by recognising the fossil fuel’s role in keeping the lights on during peak electricity demand, according to a leaked document seen by EURACTIV.

The EU executive is currently drafting a rulebook for sustainable finance, drawing up a complete set of criteria defining what can be considered as a “green” investment in the European Union.

The message hasn’t reached South Korea, now proposing a wind ‘farm’ *SEVEN* times bigger than anything yet seen.

STOP THESE THINGS

Oh yes, they’re the great pretenders: useless in calm weather or after the sun goes down, wind and solar can never really compete with coal, nuclear or gas.

And anyone trying to convince you otherwise, ought to be gently encouraged to seek psychiatric help.

Especially after America’s big freeze left millions of wind and solar ‘powered’ Texans freezing in the dark.

Comparing ever-reliable coal, nuclear or gas with never-reliable wind and solar is patent nonsense; and only an eco-loon or renewable energy rent seeker entertains that process.

In the latter case, it’s because the wind and solar rort depends upon the engineered pretence that wind and solar are cheaper than the rest.

Ever insightful, Donn Dears takes a look at the number games played by America’s wind and solar crowd in their efforts to pretend to be playing in the big league.

Solar power complex in California [USA. Gov – BLM – Bureau of Land Management]


It was already known that PV systems dislike high heat, which is clearly awkward when they depend on the biggest heat source in the *solar* system in order to be of any use. This study tries to quantify the problem in more detail. On the face of it, carpeting desert regions with solar panels looks less than ideal.

Lowering the operating temperature of solar panels by just a few degrees can dramatically increase the electricity they generate over their lifetime, KAUST researchers have shown.

The hotter a panel gets, the lower its solar power conversion efficiency (PCE) and the faster it will degrade and fail, says TechXplore.

Finding ways to keep solar panels cool could significantly improve the return on investment of solar-power systems.

The Bavarian village of Gundremmingen is so proud of its nuclear power station that its coat of arms is graced with a giant golden atom, says TechXplore.

But change is coming to the village, with the plant facing imminent closure under Germany’s decision to abandon nuclear energy following the 2011 Fukushima meltdown in Japan.

Gundremmingen is not the only German village facing big changes as the country strives to implement its energy transition strategy.

The UK and EU seem determined to make these obvious power generation
mistakes that will inevitably lead to much higher prices and blackouts, sooner or later.

STOP THESE THINGS

Sitting freezing or boiling in the dark provides a moment to consider where one’s electricity comes from. Californians, South Australian and now Texans have all enjoyed the experience, one way or another.

The common thread, of course, is an obsession with sunshine-dependent solar and/or weather-dependent wind power.

The belief that we’re just a heartbeat (and a few TWhs worth of lithium batteries) away from an all wind and sun powered future is not just delusional, it’s dangerous.

Modern, civilised society depends upon having power as and when we need it. Not merely those occasions when Mother Nature feels inclined to deliver it.

The temporary loss of electricity to provide light, heating or air-conditioning might be an irritating inconvenience. But for the aged, the infirm and those on life support it’s no laughing matter.

Then, behind the curtain, there are a raft of critical systems – including communications (think mobile phone…

Government estimates usually mean ‘not less than’, but this is worse than that.

By Larry Bell ~

Texas just sent a very chilling message to the rest of the nation about what to expect your life to be like with President Biden’s “Build Back Better” plan AKA, “Green New Deal,” in order to save the planet from overheating.

It seems he’s already overachieving that goal.

An unusual Arctic blast that spread across the state from the tip of the Panhandle all the way to the Rio Grande Valley has left millions of homes and businesses here without electricity.

A series of forced rolling blackouts were required to prevent power grid collapse as single-digit temperatures froze wind turbines and hobbled dozens of power plant operations.

How could this possibly happen here in Texas?

This isn’t supposed to be California, after all, where over-dependence on wind and solar power destabilized the grid during a record 2020 heat wave.

This week debates have heated up about the world’s shift away from fossil fuels, as frigid temperatures have wreaked havoc from Turkey to Texas, says PEI.

Let’s start in the USA. It’s the first time in 17 years that such a large portion of the US has been covered with snow and rolling blackouts have meant many have been without power, exposed to freezing temperatures.

Utilities are struggling to keep the power on as wind turbines have frozen and natural gas flow was impeded from frozen pipes.

According to USA Today: “In Texas, more than 1.6 million homes and businesses remained without power late Wednesday night, and some also lost water service”.

As is the case in many emergency situations, folks are looking for someone or something to blame. This time, the focus is on failing renewables – like the frozen turbines – with people questioning the shift from coal and natural gas, viewing it as unwise and risking baseload reliability.

The global race to produce hydrogen offshore

Offshore wind farm [image credit: Wikipedia]


Production will obviously be as intermittent and therefore as unreliable as the wind itself. And how does the hydrogen get back onshore? Yet more expense is implied. Or if the plan is to use ‘excess’ energy, that suggests power already being sent to the national grid, so why not produce the hydrogen onshore?

Last year was a record breaker for the UK’s wind power industry, says BBC News.

Wind generation reached its highest ever level, at 17.2GW on 18 December, while wind power achieved its biggest share of UK energy production, at 60% on 26 August [Talkshop comment: cherrypicking].

Yet occasionally the huge offshore wind farms pump out far more electricity than the country needs – such as during the first Covid-19 lockdown last spring when demand for electricity sagged.

But what if you could use that excess power for something else?

Gormless PM struggles to grasp his only solution to RE crisis.

The wind and solar industries were built on lies, run on myth and are fuelled by subsidies, so the only way forward is more of the very same.

It took politicians and punters around a decade to cotton on to the hopeless unreliability and chaotic intermittency of solar and wind power.  Which required an altogether new approach from the rent seekers’ spin doctors.

Over the last year or two, mythical mega-batteries have been pitched as the perfect answer.

But the economics clearly don’t stack up: the biggest battery in the world – that cost taxpayers a cool $150,000,000 – sits in a sheep paddock near Jamestown in South Australia’s mid-North and would power that purportedly wind and solar ‘powered’ state for all of four minutes when the sun sets and calm weather sets in.

Hardly bang for buck, particularly…
