Wind Turbine Troubles…..They’re Definitely NOT Safe!

The scandal of UK’s death-trap wind turbines: A turbine built for 115mph winds felled in 50mph gusts. Dozens more affected by cost-cutting. Why residents living in their shadow demand to know – are they safe?

Health and Safety Executive release reports on collapsed wind turbines
Causes were manufacturing faults and basic installation mistakes
Campaigners believe the risk of turbines collapsing will continue to grow

PUBLISHED: 22:36 GMT, 13 September 2014

It was just before midnight on a winter’s night last year. Outside in the gusting January wind it was freezing, but Bill Jarvis was sitting by the fire with his wife Annie and a few relatives in their cottage on the North Devon moors.

And that’s when they heard it: a tremendous ‘crack’, louder than a thunderclap.

‘We rushed outside wondering what on earth had happened,’ recalls Bill. ‘We thought perhaps a plane had crashed it was such a loud noise. ‘We couldn’t see flames or anything burning, even though we peered out in the direction it had come from. There was nothing else though, no more noise or aftershocks.’

Collapsed: The turbine that fell at East Ash Farm, Bradworthy had been installed with the wrong configuration of nuts at its base, upsetting its balance

Deafeningly loud it might have been, but what the Jarvis family had heard – as they were to discover the following morning – had taken place at Bradworthy, a mile away. It was the noise of a 115ft-high wind turbine crashing to the ground.

‘It’s pretty terrifying stuff,’ says Mr Jarvis. ‘I’m no fan of the things and this has just added to my worries. Just think what could have happened. It sends a shiver down your spine.’

He is not the only one feeling nervous about the march of the giant metal windmills across the British landscape.

This week, the Health and Safety Executive (HSE) produced two reports – one into the catastrophic failure of the Bradworthy turbine and another into the collapse of a turbine in the next county, Cornwall, just three nights later.

And its conclusions are not merely unsettling, but have frightening implications for wind turbines and their safety right across the country.

Man down: The wind turbine at Winsdon Farm, North Petherwin, Cornwall, fell due to a fault with the components, resulting in a failure in the foundation rods concreted into its base

The turbines in Devon and Cornwall came down when the wind was blowing at barely 50mph, despite the fact that they are supposed to withstand blasts of just over 115mph.

And, as the HSE concluded, the causes were manufacturing faults and basic mistakes in the way they were installed. The errors have already been replicated elsewhere in the country, as the two reports make clear, and could affect dozens – if not hundreds – more of the giant towers.

It is hardly encouraging to learn that the HSE reports were not published in a normal sense, but were available only on request.

They have come to light now only through Freedom of Information (FoI) requests lodged by a number of concerned residents.

Dr Philip Bratby, from CPRE Devon, believes the risk of collapse will continue to grow as long as the wind industry is allowed to operate behind a wall of secrecy.

A retired physicist, who formerly worked in nuclear energy, he says: ‘Safety standards in my line of work were paramount. We constantly monitored, tested and maintained equipment but this does not seem the case with turbines.

‘These two failures were catastrophic. The towers came crashing down with great force from a great height.

‘It was only down to luck it happened in the night and no people or animals were injured or killed.

‘The wind industry is very secretive about everything it does. It won’t publicise any definitive information about accidents so it is impossible to make an independent assessment of the risks.’

Dr Bratby lives at Rackenford, high on the edge of Exmoor, where there has also been a proliferation of turbines.

‘I am not convinced that we are learning from the bad experiences and feeding those lessons back into the education of designers and constructors because the industry is growing so rapidly,’ he says.

‘The size of these turbines seems to keep on increasing and I believe the dangers will increase accordingly. The bigger the turbine that fails, the bigger the potential for disaster and death.’

Turbine towers are supposedly secured by lowering them on to a series of foundation rods that emerge vertically from a concrete foundation.

These are levelled by the adjustment of bottom nuts below a flange at the base and then fixed with another set of nuts above the base.

Campaigners believe the risk of turbines collapsing will continue to grow as long as the wind industry is allowed to operate behind a wall of secrecy

All the exposed metal, including the rods and the nuts, is then encased in grout which protects it and spreads the stresses from any movement in the turbine.

Yet as these groundbreaking HSE reports show, not only were some of the parts faulty, two different sets of sub-contractors made the same basic – possibly cost-cutting – errors. And the result was that the metal monsters were not secure at all.

In the incident at East Ash Farm, Bradworthy, on January 27, 2013 – the one heard by Mr Jarvis – an E3120 model, made by Canadian-based Endurance, was found to have been installed with the wrong configuration of nuts at its base.

This upset the ‘loadings’, or balance, of the tower. The implication is that it wasn’t level. To compound the problem, the contractors who installed it had failed to use structural-grade grout to seal the rods and bolts from the worst of the weather and had used a ‘cosmetic’ compound instead.

The HSE reports reveal that the same faulty configuration of nuts had been to blame at Wattlesborough, near Shrewsbury in Shropshire, the previous year when another E3120 collapsed.

To date, Endurance has erected 300 of the E3120s throughout the United Kingdom.

The UK arm of the company says it has inspected all of them and carried out urgent repairs on 29 of the towers.

A different type of turbine fell at Winsdon Farm, North Petherwin, Cornwall, on January 30. This was a G133, manufactured by Gaia-Wind, originally a Danish firm.

This time there was a fault with the components, resulting in a failure in the foundation rods concreted into its base. But again, it had been badly installed with a lack of grout. As the HSE inspector concluded, there was ‘a lack of resilience to the fatigue loading within the securing arrangement… and poor fatigue strength in the securing components’.

The collapse of another G133 turbine at Otley, near Leeds, in April 2013 occurred in identical circumstances. Again, the securing rods were substandard. Once again, they had not been properly grouted in place.

As Dr Bratby points out, the footings and securings, which are difficult to inspect when encased in concrete and grout, are critical because they are subject to such huge and varying forces.

‘Over time they clearly degrade to the point of failure,’ he says. ‘We should be asking ourselves whether we are at a tipping point as the first-generation technology is exposed and compromised.’

Green energy: Wind turbines and windfarms provide a renewable alternative

Dr Bratby is frustrated at the lack of risk assessments undertaken when looking at sites.

He says: ‘I accept that the dangers from wind turbines located on farms without public access and remote from public rights of way are probably acceptable.

‘That is not always the case. They have been located close to roads and railways, at workplaces, in schools, hospitals and parks without any formal assessment of the dangers. I think that is unacceptable.’

His views are shared by fellow campaigner Alan Dransfield, from Exeter, who helped to mastermind the FoI application.

‘These reports took the best part of a year and several thousand pounds to compile, and the HSE decided to investigate because of the extensive media coverage and widespread public concern,’ Mr Dransfield says.

‘I’m delighted they did because look what they’ve found. Without doubt there is an urgent need for a more proactive stance with regard to the wind-turbine industry. It clearly can’t police itself.’

Taken together, there are 380 E3120 and GI33 towers. Of these, four are known to have collapsed, while repairs were necessary in 39 others to prevent potential further collapses.

Meanwhile, an as yet undisclosed number have further problems with the way they are bolted down, according to the HSE, and need repairing as soon as possible.

Revealing as they are, however, the two new reports deal with only a small minority of British turbines: there are 6,500 of differing design and manufacture across the country, and when it comes to problems with collapse or faulty installation, the public is wholly in the dark.

Figures from Caithness Windfarm Information Forum, a wind-turbine monitoring website, show that structural failure is the third most common major fault, behind blade failure and fire.

It has recorded an average of 149 accidents worldwide every year between 2009 and 2013 but believes this to be the ‘tip of the iceberg’ as it relies on scanning the internet for reports of such incidents.

‘The trend is as expected – as more turbines are built, more accidents occur,’ says a spokesman. ‘The numbers will continue upwards until the HSE helps force significant change.

‘In particular, the public should be protected by declaring a minimum safe distance between new turbine developments and occupied houses and buildings.’

However, Chris Streatfeild, director of health and safety with Renewable UK, the industry trade association, believes that any fears of wind power are unfounded and the risks minimal and acceptable.

‘Manufacturers, installers and owners work hard to ensure that they meet extremely stringent health and safety standards,’ he says.

‘There’s a rigorous process, verified by independent bodies, to ensure strict installation standards and safe siting. That’s why problems are so rare.’

He adds: ‘When incidents do occur, it’s important to learn from them and implement any lessons fully and promptly. Any serious incident has to be reported to the HSE and we work closely with them to ensure high standards are maintained.

‘To put this into its proper context, no member of the public has ever been injured by a wind turbine. It’s unfortunate a handful of anti-wind campaigners are choosing to indulge in scaremongering.

‘Climate change is a real and pressing issue. When it comes to generating clean electricity, onshore wind is the most cost-effective way so we should be making the most of it.’

At Bradworthy, farmers Des and Vera Ludwell were also staying quiet about their windmill. A new turbine stands in the position of its collapsed predecessor, about 50 yards from the road. A second one is even closer, leaving little safety margin.

Councillor David Tomlin revealed there are 50 turbines within a six-mile radius of Bradworthy, a quiet market town, and a further 20 have been approved.

‘We are not anti-wind power as such,’ he says. ‘But there is a visual intrusion and residents who live close to turbines report a constant whooshing noise from blades. Most importantly, can we still be certain they are safe?

‘What happened here and in Cornwall and analysed in detail in these two reports should be a wake- up call. Perhaps we should halt the erection of further turbines pending an investigation of the industry as a whole.’

An earlier version of this article said the HSE reports had been published in redacted form. We would like to make clear this was incorrect and the full reports have been available.

How to Fight the Great Wind Power Fraud

September 17, 2014 by stopthesethings

In this post we documented over 2,000 Anti-Wind Power Fraud groups operating world-wide, fighting to protect their homes, farms, families and communities from being overrun and destroyed by giant industrial wind turbines.

The battles being waged have a common enemy, but the tactics and strategies employed are diverse – and, unfortunately, in some cases play into the hands of wind power outfits, their advocates and apologists.

In Australia, when the battle to save communities began some years back, the usual response from those opposed to wind farms was along the lines of: “we’re all in favour of renewable energy, so long as wind farms are built in the right place”.

Thankfully, it’s a line rarely heard these days as people switch on to the scale and scope of the great wind power fraud – and open their eyes, for the first time, to the phenomenal cost of the subsidies directed at wind power through the mandatory RET (see our post here) – and the impact on retail power prices (see our post here).

Fair minded country people are usually ready to give others the benefit of the doubt; and, not used to being lied to, accepted arguments pitched by wind power outfits about the “merits” of wind power: guff like “this wind farm will power 100,000 homes and save 10 million tonnes of CO2 emissions” (see our post here).

Not anymore.

Apart from the very few farmers that stand to profit by hosting turbines, rural communities have woken up to the fact that wind power – which can only ever be delivered at crazy, random intervals – is meaningless as a power source because it cannot and will never replace on-demand sources, such as hydro, gas and coal. And, as a consequence, that wind power cannot and will never reduce CO2 emissions in the electricity sector. The wind industry has never produced a shred of actual evidence to show it has; and the evidence that has been gathered shows intermittent wind power causing CO2 emissions to increase, not decrease (see our post here and this European paper here; this Irish paper here; this English paper here; and this Dutch study here).

The realisation that the wind industry is built on series of unsustainable fictions has local communities angrier than ever and helps explain the phenomenal numbers opposed to wind farms within those communities: 90% or more in plenty of cases (see our post here).

However, if your group (wherever it is) is still running the line that: “there’s nothing wrong with wind farms just as long as they’re in the right place”, you might as well run up the white flag now. Likewise, if your pitch is based on a proposed wind farm’s negative impact on your visual amenity.

When arguments like these are reduced to their common denominator they’re all based on the “my patch of paradise is special, so go and find somewhere else” proposition.

Wind farm developers have faced that pitch thousands of times in hundreds of places. Their obvious response is that ALL of these places can’t be “special”; governments set up policies to save the planet; therefore, wind farms have to go somewhere, so it may as well be at [insert place name], right next to your place ….

Having stuck with a “wind farms are alright somewhere else” case, pro-community and pro-farming groups find themselves being steamrolled by the combined forces of lying, cheating wind farm developers and corrupt planning systems.

STT thinks your group will have far more success if you don’t concede that there is any right place for a wind farm, anywhere, ever.

STT has hammered the fact that wind power is both an economic and environmental fraud, making it plain that there is never a “right” place for any wind farm: we’d like to think that we’ve got that message across; to the benefit of many, we hope.

While the wind industry in Australia is on its knees, there are plenty of threatened communities here still taking it up to slimy developers and bent planning panels, to make damn sure that the country surrounding their towns, farms and homes remains turbine free.

In any battle, it is always sound practice to settle on a strategy from the beginning and to stick with it, no matter what the enemy throws back.

Fighting planning battles at the local level requires a different strategy than that required to get the Federal government to chop the mandatory RET, where the case to kill the wind industry is largely about subsidies and power prices. However, there are some arguments that will win traction in both forums; such as the absurdity of trying to rely on a power source that has to have 100% of its capacity backed up 100% of the time by conventional generation sources, among others.

If you’re engaged in a local battle, STT thinks that this wrap up from American Physicist and Environmental Activist, John Droz Jr is as good a template as you’ll find.

An Analysis of Anti-Wind Farm Strategies
John Droz Jr
16 May 2009

As a “concerned citizen” I often (probably too frequently) find myself in the situation of trying to fix some type of community problem — like propagating wind power.

Through years of valiant efforts — often successful but sometimes not — one thing I have learned is that being right isn’t enough. As a scientist, this concept is not intuitive to my way of thinking. It generally seems to me that the facts should determine the outcome.

But no, people being people, that often is not what happens.

This had lead me to a greater appreciation of the value of Public Relations. Most people do not understand Public Relations very well, as they confuse it with “advertising”, or categorized as a “pseudo-science” that amounts to a lot of subjective opinions. It’s neither.

I now understand Public Relations as really meaning “effective communication.” Clearly any issue stands a better chance of being resolved when there is better communication.

Public Relations is most applicable at public meetings, Letters to the Editor, websites, etc.

So how does this apply to local groups or environmental organizations who are against industrial wind power?

Since you will be up against well-financed businesses, money-focused politicians, and maybe even well-intentioned (but misinformed) environmental organizations, it is critical that your group employ a well thought out strategy if you have any hope of success — and there HAVE been grassroots groups that were successful in fighting off wind developers.

In my opinion, by far the most important decision that needs to be made is exactly where you want to have the battle, and then carefully controlling things to keep it there.

The problem I see with most groups trying to resist the wind power conglomerate, is that they are fighting the war on the wrong front.

These groups say something like “we will accept wind power if it is sited properly.” Then they work to get “proper siting” to deal with one or more (legitimate) concerns: noise levels, bird flyways, habitat destruction, property devaluation, view setbacks, etc.

In my opinion, this is a MAJOR and usually lethal mistake. Here’s why:

1 – This position amounts to a counter-proposal to the developers: that if the turbines are moved X feet in some direction, then the project will be acceptable. Implicit in that is an admission that wind power really works.This admission is erroneous and is usually fatal.

2 – Once the developers have your acknowledgment that wind power will work (with just a different positioning of turbines), they will then focus on undermining your proposed adjustments. They do this by bringing in their experts who dispute your noise, etc. findings.

The result usually is that it ends up being “He says, She says”. There is almost never a clear cut victory for you on such points — even though you may well be 100% right!

3 – Let’s say that the developer agrees with your objection and moves the wind towers X feet in some direction. Are you saying that this is now a good thing, that these wind towers are now an asset to your community?Hopefully not, but that is also implied with this strategy.

4 – Framing your group’s position as a siting issue gives the appearance (right or wrong) that this is a NIMBY matter. Be assured that the proponents will put it that way.

5 – You are unlikely to get widespread public support using such tactics, because if another community member isn’t personally affected by your issue (e.g. noise levels) then they could probably care less. You need broad public support!

6 – Another problem in garnering public support is presenting multiple, technical issues for average citizens to absorb. What does Joe Public know about acceptable decibel levels?

7 – Going down this path will also likely fracture your group. Some will want certain issues front and center, others will want different ones. This is not a recipe for success.

8 – Even under the best circumstances — that you prove your point (e.g. that in some cases the noise will be too loud), you will then have to deal with their trump card:

“Yes that may be so, but we all have to make real sacrifices to save the planet.”

Now what are you going to say? Effectively you’ve lost.

All this happened because of one thing: you fought the wrong battle.

————————————————————————————————————

Let’s start over. Your one position is that you support sound scientific solutions — and wind power is not acceptable as: it fails to deliver the goods.

By this you mean that wind energy:

1) is not a technically legitimate solution for our grid, or to meaningfully reduce CO2, and

2 is not a commercially viable source of energy on its own; and

3) is not environmentally responsible.

Those basic criteria haven’t been selected to make wind power look bad, but are what should be used to evaluate the legitimacy of any proposed new alternative source of energy. You are not against global warming or renewable energy or economic incentives: you are only against proposals that don’t make good scientific sense.

Here are some benefits of this approach:

1 – You are on MUCH stronger technical ground than you would be on any of the secondary issues, as the wind power industry does NOT have proof — anyplace in the world — that CO2 has been materially reduced, or that any coal power plant has been shut down due to wind power added to the grid.

Since there are some 100,000 wind turbines now in operation world wide, such evidence should be plentiful and easy to produce. Maybe it has been too long since I got out of graduate school, but my recollection of how science is supposed to work is this:

When a new idea is proposed as a potential solution of a problem, it is up to the solution proponents to PROVE its efficacy — not the other way around.

Here we have businessmen, investors and politicians proposing wind power as part of an energy “solution” to global warming. So the ball is in their court as to providing independent, objective proof that wind poweris a viable solution from all pertinent perspectives. THIS HAS NOT YET HAPPENED, and your group should stay focused on that significant vulnerability of theirs.

2 – Once you fully absorb the understanding that wind power does not work, then you can see the foolishness of saying that it is OK if it is “sited properly.” {Exactly what is proper siting for something that does not work?} Since siting is no longer a major issue, there is an increased likelihood that (if you win) that there will be NO wind project in your community. Isn’t that a MUCH better result than getting one with setbacks?

3 – Once you get your members educated, they can ALL be on the same page. Who would be in favor of something that doesn’t work?

4 – Your group will no longer come across to the public as a fractured collection of malcontents trying to protect some niche area of personal interest.

5 – It will be easier to educate the public on this one issue.

6 – You can still bring in some secondary issues (but only as need be) under the auspices of “wind power is not environmentally responsible because…”.

7 – Taking this approach will less likely result in criticism of your group being NIMBYs.

Saying that you are against something because it doesn’t work, is quitedifferent from saying that you are against it because it’s in your backyard.

8 – You are also less likely to be labeled as anti-green, because you are infavor of green solutions to our energy situation — but wind power isn’t green and isn’t a meaningful solution. There are alternative energy sources that better meet the science/economics/environmental tests much better than wind: like geothermal.

9 – The only good reason to support setbacks is to make them so restrictive that the cost of the project becomes prohibitive and the developer leaves. It is important to do this ONLY after making clear that your position is that wind power does not work. [An excellent example of scientifically based setbacks is from an ordinance in Trempealeau County, Wisconsin. Find this and others at my site <<http://www.wiseenergy.org>>.]

10 – Most importantly of all, the “it doesn’t work” strategy removes the developer’s trump card. There is no “sacrifice for the planet” anymore, as you have proved that his development doesn’t help the planet one whit.

————————————————————————————————————

Hopefully this should show you which path is in your best interest. Let’s say you take my suggestion and fight on the “It doesn’t work” front. Are you still home free?

Almost, but they will likely throw out a new trump card: “OK it may not work, but look at all the money our community will get!”

That’s good as you will have successfully ferreted out the real driving force here: MONEY.

Here’s how to deal with that:

1 – Anticipate this ending, at the beginning. Get your town board (or whoever is advocating this) to make a commitment before you show your hand. Get on the pubic record their answer to your question: “Are you supporting this project because of the global warming benefits, or the money?” It is almost 100% assured that they will say the former.

2 – Now at the end, you bring out their documented position and say that you have addressed their good objective of helping with global warming, and shown that this project does NOT help. Therefore you expect them to be good to their word and not support it.

3 – You can point out the fact that the money that the developer is so generously tossing around is not through his own largess — it is taxpayer money in the first place. Are we really so gullible that we can be bribed with our own money?

4 – Let’s say that they now admit that it’s only all about the money. This is where you put that position in context. “OK, what I hear you say is that you want to bring money into our community — despite the fact that wind power has no other meaningful benefit to anyone, and despite the fact that wind power has proven environmental liabilities. Well then I ask you, since this seems to be your thinking, what’s next?”

“Should we expect that you will be signing us up for a regional landfill? How about a toxic chemical plant? How about a slaughterhouse? Maybe a prison for terrorists? Should we clear-cut all our trees to cash in on their value? Maybe a strip mining operation? How about selling our water to Nestle to bottle? These businesses would also employ people and pay taxes — just like wind power.”

“We live here. We work here. We have brought up our children here. Our life is here. What is at stake here is our quality of life. As our representative, we want to make this very clear: our quality of life is not for sale at any price.”

If done right, this approach will have widespread community support, and that is your best chance for victory.

————————————————————————————————————

Let’s wrap it up here and just say that despite ALL your good efforts that your representatives refuse to listen to reason, and still choose not to do the right thing.

Unfortunately, it happens!

In brief you have two options: a) replace them, or b) sue them.

The obvious way to replace a person who is a poor representative is to vote them out. But how do you do this if they are entrenched in the system, or elections are a long way off?

One strategy that does work is to get them to resign, through public pressure. (Again you only embark on this option after you have exhausted the polite attempts at conversion.)

Another effective tactic is to form a Political Action Committee (PAC). Since this is a legal matter, it is discussed in our Some Legal Optionsreport (see wiseenergy.org).

The good news is that if you have gone about this in the proper way, then you have set the stage for a lawsuit (a latter level recourse) that is likely to be successful.

Because there is a lot to the legal aspect topic, please refer to the aforementioned Some Legal Options report for more information.

Whatever your strategy, to be successful your group must get a sound understanding of the wind power matter before taking on the developers or local politicians.

There is a wealth of applicable information at my web page: <<http://www.wiseenergy.org>>. Please consider the findings of independent, environmentally concerned scientists that are listed at that page, especially “Essential Reading” which also has more links to detailed information.

Self-Destructing Wind Turbines…..a Brilliant Idea!

New Wave of Turbine Terror: Brits Brace as Giant Fans Keep Collapsing

September 16, 2014 by stopthesethings 1 Comment

A while back we covered what the wind industry and its parasites call “component liberation” in our post – Life in the “throw zone” which included video of a Vestas’ turbine “liberating” its components.

That led to a retort from an employee from AGL’s Macarthur wind farm disaster – calling himself “Prowind” – about the exploding turbine – “that turbine in the video is not accident, they purposely let it self destruct. That is NEVER going to happen at MacArthur.”

We dealt with “Prowind” in our post – Logic: not found on other planets?– which included a serious scientific study into the distances blades are likely to travel during “component liberation”. The study dealt with over 37 “component liberation” events, recording blade throw distances of up to 1,600 m.

And we covered a turbine liberating its components in a schoolyard at Caithness, Scotland in this post: Remember the days of the old school yard?

We also covered – yet another component liberation – in our spoof post –IWTs or WMDs?

The obvious irony and sarcasm in that post was lost on greentards – a humourless bunch at the best of times – which prompted us to explain the difference between the literal and the figurative – in this post – It’s all about the costs, stupid.

Not only are giant fans determined to “liberate” their blades all over the countryside, schools and homes, these friendly little puppies are just as keen to collapse, laying waste to anything in their path.

Here’s a wrap up from the UK on the terror and havoc being caused by collapsing turbines.

The scandal of UK’s death-trap wind turbines:
The Mail on Sunday
Simon Trump
14 September 2014

A turbine built for 115mph winds felled in 50mph gusts. Dozens more affected by cost-cutting. Why residents living in their shadow demand to know – are they safe?

Health and Safety Executive release reports on collapsed wind turbines
Causes were manufacturing faults and basic installation mistakes
Campaigners believe the risk of turbines collapsing will continue to grow

And that’s when they heard it: a tremendous ‘crack’, louder than a thunderclap.

‘It’s pretty terrifying stuff,’ says Mr Jarvis. ‘I’m no fan of the things and this has just added to my worries. Just think what could have happened. It sends a shiver down your spine.’

He is not the only one feeling nervous about the march of the giant metal windmills across the British landscape.

And its conclusions are not merely unsettling, but have frightening implications for wind turbines and their safety right across the country.

The turbines in Devon and Cornwall came down when the wind was blowing at barely 50mph, despite the fact that they are supposed to withstand blasts of just over 115mph.

It is hardly encouraging to learn that the HSE reports were not published in a normal sense, but were available only on request and in redacted form.
