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.

The makers say: ‘Vortex Bladeless is a vortex induced vibration resonant wind generator. It harnesses wind energy from a phenomenon of vorticity called Vortex Shedding. Basically, bladeless technology consists of a cylinder fixed vertically with an elastic rod. The cylinder oscillates on a wind range, which then generates electricity through an alternator system.’

New tech developments are happening in the wind power sector, says ZME Science.

Wind power is mostly associated with sweeping white blades, taking advantage of the strong gusts that blow over the land or the sea.

But what if we could forget about the blades and even the wind and instead just have a turbine?

That’s the idea of a group of European companies, who have come up with new ways to expand wind energy without the limitations of a conventional turbine.

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.

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…

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?

A New Form of Space Weather: Earth Wind

A water creation surprise here.

Spaceweather.com

Feb. 12, 2021: The sun is windy. Every day, 24/7, a breeze of electrified gas blows away from the sun faster than a million mph. Solar wind sparks beautiful auroras around the poles of Earth, sculpts the tails of comets, and scours the surface of the Moon.

Would you believe, Earth is windy, too? Our own planet produces a breeze of electrified gas. It’s like the solar wind, only different, and it may have important implications for space weather on the Moon.

“Earth wind” comes from the axes of our planet. Every day, 24/7, fountains of gas shoot into space from the poles. The leakage is tiny compared to Earth’s total atmosphere, but it is enough to fill the magnetosphere with a riot of rapidly blowing charged particles. Ingredients include ionized hydrogen, helium, oxygen and nitrogen.

Once a month, the Moon gets hit by a blast of Earth wind. It…

Pipistrelle bat [image credit: Drahkrub @ Wikipedia]


Their activity in the danger area seems to be mainly on nights with light winds and warm temperatures, but pinpointing the most relevant sites is not straightforward.
– – –
One of the most abundant bats in Europe may be attracted to wind turbines, a new study shows.

The activity of common pipistrelle bats was monitored at 23 British wind farms and similar “control” locations close by without turbines, reports Phys.org.

Activity was around a third higher at turbines than at control locations, and two thirds of occasions with high activity were recorded at turbines rather than the controls.

The reasons for this are not clear.

This has echoes of the ice age dust/albedo theory – with no CO2 feedbacks – proposed by Ralph Ellis a few years ago. The article concludes: ‘The result thus has the potential to aid the understanding of the abrupt warming and cooling periods during the ice ages called Dansgaard/Oeschger events which bear the marks of climate tipping points.’

– – –
Every late winter and early spring, huge dust storms swirled across the bare and frozen landscapes of Europe during the coldest periods of the latest ice age, says Phys.org.

These paleo-tempests, which are seldom matched in our modern climate frequently covered Western Europe in some of the thickest layers of ice-age dust found anywhere previously on Earth.

This is demonstrated by a series of new estimates of the sedimentation and accumulation rates of European loess layers obtained by Senior Research Scientist Denis-Didier Rousseau from Ecole Normale Supérieure in Paris, France, and colleagues.

The work, which is published in Quaternary Science Reviews is part of the TiPES project on tipping points in the Earth system, coordinated by The University of Copenhagen.

In the study Denis-Didier Rousseau and colleagues reinterpreted layers in loess from Nussloch, Germany.

Loess is a fine-silt-sized earth type found all over the world. It mainly consists of aeolian sediments, which are materials transported by the wind from dry areas without vegetation such as deserts of any type, moraines, or dried-out river beds.

Within the aeolian sediments, darker layers of paleosol alternate within the loess layers. Every layer in the loess represents a shift in climatic conditions.

Airlines could save fuel and reduce emissions on transatlantic flights by hitching a better ride on the jet stream, new research has shown.

Scientists at the University of Reading have found that commercial flights between New York and London last winter could have used up to 16% less fuel if they had made better use of the fast-moving winds at altitude, says TechXplore.

New satellites will soon allow transatlantic flights to be tracked more accurately while remaining a safe distance apart.

Combining wind power with a nuclear small modular reactor (SMR) could see energy production re-start at Wylfa in North Wales by late 2027 under plans presented by Shearwater Energy, says New Civil Engineer.

Shearwater has said that the proposal would involve construction of a wind-SMR and hydrogen production hybrid energy project, which it says would be located on a different site to the Wylfa Newydd nuclear power station, planned by Horizon, that stalled when Hitachi pulled support last year.

The Shearwater plant could provide 3GW of zero carbon energy and is also expected to produce over 3M.kg of green hydrogen per year for use by the UK’s transport sector.

The perpetual mismatch between supply and demand of wind power can only get worse as more of it is built. Energy storage can’t resolve these problems, only reduce them slightly at best.

Introduction

We have all heard that wind power generation is intermittent, that it goes up and down on a daily basis. However, is that really all that much of a problem, and if so, how big a problem is it? We have also heard that constructing more wind plants will go towards alleviating this problem. Is that correct? Or will that only make the problem worse?

Well, it is in fact quite a large problem, and constructing more of those wind plants is making the problem worse.

Macarthur Wind Plant In Victoria Australia

For many years now, I have been looking at wind power generation here in Australia, and in fact recording and keeping wind generation data on a daily basis now for more than four years. After looking at this data on a daily basis for so long, I could see that it went up…

Windfarm objection in Galloway


The suspicion may exist that the ruling Scottish Nationalist Party never seems to win in this sparsely populated region, so is not inclined to much sympathy for its residents when making decisions on the many windfarm applications.
– – –
Residents are moving away from parts of south-west Scotland because they are losing much of the local landscape to wind farm developments, it has been claimed.

Now Trevor and Elaine Procter, who live at Knockvennie, near Dumfries, are urging people to contact local councillors to object to the “tsunami” of planning applications for such developments, reports The National (via Wind Watch).

They have lived in their current home for 12-years, and Trevor said the effect on locals was comparable to the Highland Clearances.

The UK intends to have many more expensive wind turbines scattered all over the place, often in remote areas or offshore. How best to prevent, or deal with, fires is a question that can’t be swept under the carpet to maintain a false image.
– – –
Why the wind industry cannot afford the financial and reputational damage that even a single turbine fire can bring.

The wind industry has underestimated fire risk for decades, says Angela Krcmar @ Power Engineering International.

Even now, statistics around fire losses are based on estimates and incomplete datasets.

For a time, the industry could get away with not fully managing fire risk, as the size and number of assets per owner were low enough for many to not experience a fire in their portfolio.

However, as turbines begin to scale up and wind takes on a greater share of national energy mixes across Europe and North America, the industry cannot afford the financial and reputational damage that even a single turbine fire can bring.

Wind turbines catch fire primarily due to electrical or mechanical faults leading to ignition which spreads to the surrounding plastics and fibreglass nacelle.

Turbine fires tend to originate in the nacelle at one of three points of ignition – converter and capacitor cabinets, transformer or the brake.

Converter and capacitor cabinets are necessary for the wind turbine to translate the variable frequency and amplitude of generated energy into a constant frequency and voltage that can be fed into the grid.

However, an electrical fault at these components can produce arc flashes or sparks, which can surround plastics in the cabinet and result in a fire. Transformers, which similarly convert energy into an appropriate voltage for the grid, can also be a point of ignition due to electrical faults.

Nacelle brakes are utilised in an emergency along with blades pitching to stop the turbine blades from spinning in seconds. This generates an enormous amount of friction and heat, and a mechanical fault at the nacelle brake can easily result in a fire.

Financial risk of fire

The rate of fires has remained consistent over the past decade according to available data – typically one in every 2000 turbines will burn down every year.

While technologies which are less susceptible to fire such as electric braking systems have been developed, many of the key ignition points are necessary for electricity generation and as such, cannot be designed out of the turbine.

While the frequency of fires has remained constant over the years, the financial risk of fire has increased with the size and complexity of turbines.

As turbines are getting increasingly bigger and therefore more expensive, a single fire can have a much greater impact.

Even the normally alarmist BBC has to admit that ‘a La Niña event normally exerts a cooling influence on the world’. Add in a deep solar minimum and things could get interesting, with varying regional effects.
– – –
A moderate to strong La Niña weather event has developed in the Pacific Ocean, according to the World Meteorological Organization (WMO).

The naturally occurring phenomenon results in the large scale cooling of ocean surface temperature, says BBC News.

This La Niña, which is set to last through the first quarter of 2021, will likely have a cooling effect on global temperatures.

But it won’t prevent 2020 from being one of the warmest years on record.

La Niña is described as one of the three phases of the weather occurrence known as the El Niño-Southern Oscillation (ENSO).

This includes the warm phase called El Niño, the cooler La Niña and a neutral phase.

Is he tilting at windmills like Don Quixote? Victor Hill @ Master Investor is asking.

The vision thing

Right now, the British prime minister’s in-tray is full – but one of the items requiring his keen attention is the UK’s commitment to transition to a net carbon neutral economy by 2050, as decreed by his predecessor, Mrs May.

During his digital address to the virtual reality Conservative Party Conference 2020, beamed through cyberspace on 06 October, one of the key themes was to build back better by harnessing a valuable resource which Britain possesses in abundance: wind.

Time for another airing of the usual tedious waffle about wind powering x number of homes, ignoring its chronic intermittency and tendency to almost disappear for hours, or even days, at a time. The greater the dependency on it, the greater the potential disruption to electricity supply. Fantasies of ‘slowing climate change’ are just that: fantasies.

Boris Johnson will promise to “build back greener” in his conference speech on Tuesday, announcing new investment in offshore wind energy, reports BBC News.

The PM will pledge £160m to upgrade ports and factories for building turbines, setting a target for wind to produce enough electricity to power the equivalent of every UK home by 2030.

The plan aims to create 2,000 jobs in construction and support 60,000 more.

He will say the UK is to become “the world leader in clean wind energy”.
