Debunking lie # 4
Posted on July 26, 2013
The fourth lie: Wind turbines make no more noise than a refrigerator.
Did you ever wake-up at night with palpitations? Many windfarm neighbors do, and it’s not because of their refrigerators. The culprit, we know now, is infrasound emitted by wind turbines, aggravated by pulsations. Governments, scientists and wind turbine manufacturers knew that as far back as 25 years ago: this is why they always refused to measure infrasound emitted by wind turbines. They know they would be in trouble if they did. But they will have to do it now, as the news of their cover-up has just hit the fan: http://blogs.telegraph.co.uk/news/jamesdelingpole/100227983/wind-turbines-are-a-human-health-hazard-the-smoking-gun/
I shall comment further on infrasound later, but for the moment I wish to say something about the noise issue. For not only has the wind industry covered-up on infrasound, it has also fudged the noise issue and told the public a big lie, namely the title of this post. One of Denmark’s leading newspapers has lambasted Vestas for it just recently:
As published on 1st July 2013 in JyllandsPosten:
Acousticians criticize Vestas
The Vestas campaign, which aims to prove half truths and myths wrong through facts, has made a serious error itself.
We need to correct our phrasing, says a Vestas spokesman.
By Axel Pihl-Andersen (Journalist, JyllandsPosten)
Vestas has just launched a global campaign, which according to the wind turbine-giant itself is a counter-attack on the anti-wind movement, which is to be put in place by the pioneering Act on Facts-campaign.
“For too long, the wind industry has allowed itself to be run over by few, but influential anti-wind movements, arguing with half truths and wild myths. Vestas now responds with a fact based global campaign, which aims to turn the passive majority of people into active advocates of wind power.” These are among the words in Vestas’ press release, which states that the campaign shall replace “hard-lived myths and lies about wind energy with documented facts”. But Vestas has large problems with the documented facts themselves, say Denmark’s leading acoustics scientists at Aalborg University.
Noise from a refrigerator
One of the campaign’s major topics is noise, and Vestas claims that the noise 400 meters away from a wind turbine is less than the noise from an average refrigerator. But that is pure nonsense, says acoustics professor Henrik Møller from Aalborg University.
“If you take a sound level meter to your refrigerator, it will register a noise level of approx. 30 dB. The sound pressure level for a wind turbine at a distance of 400 meters will be approx. 40-43 dB, and that is a very big difference. If the noise level of a refrigerator were 40 dB, it would be impossible to sell”, says Henrik Møller.
He believes that Vestas, in spite of its facts-campaign, has messed seriously around with acoustic terms. Producers of refrigerators do announce some noise levels of about 40 dB, but according to Henrik Møller, these refer to a technical measure called the sound power level, and this cannot be compared to the sound pressure level.
Two different types of decibels
“I think they have compared the sound power level from the refrigerator with the sound pressure level from wind turbines, and those are two very different measures. Decibel is not just decibel – it depends on what you are measuring”, says Henrik Møller.
Press officer and spokesman Jens Velling from Vestas admits that there is some “uncertainty” about this information. “We are aware of it, but I want to point out, that the campaign first launched is designed for Australia, where the required distance between a windturbine and a residence is 800 meters. At this distance, the numbers make sense”, says Jens Velling.
But you write 400 meters in your material? – “Yes, that is something we need to rephrase”.
It is not a good thing that you present wrong information in a campaign that is supposed to be based on facts, is it? – “No, you are right about that. It is essential, that the information we give is correct. We need to take a look at that phrasing.”
Professor Henrik Møller states that the numbers don’t make sense at 800 meters distance either. At a wind speed of 8 meters per second for a 3 MW Vestas wind turbine with a sound power level of approx. 107 dB, the sound pressure level will measure approx. 37-38 dB. This is still significantly more than the refrigerator’s 30-32 dB [ed. note: 5-8 decibels represent a huge difference for those who must live with the noise].
The National Association for Neighbours of large Wind Turbines in Denmark also criticizes Vestas’ campaign for manipulating numbers and information. “Vestas’ campaign contains much misleading information, but worst is the assertion that the noise of a wind turbine at a distance of 400 meters compares to that of a refrigerator”, they write in a press release.
The third lie: one kWh produced by a wind turbine saves one kWh produced with fossil fuels
Left or right, same campaign: save-the-planet / don’t-mind-your-wallet.
It’s the biggest con EVER.
Here is the simple truth:
Wind farms provide no useful electricity
by Richard S. Courtney, energy consultant
Electricity is wanted all the time but the demand for electricity varies from hour to hour, day to day, and month to month. The electricity grid has to match the supply of electricity to the demand for it at all times. This is difficult because power stations cannot be switched on and off as demand varies.
The problem of matching electricity supply to varying demand is overcome by operating power stations in three modes called “base load,” “generation,” and “spinning standby.”
Some power stations operate all the time providing electricity to the grid, and they are said to provide “base load.”
Other power stations also operate all the time but do not provide electricity all the time. They burn (or fission) their fuel to boil water and superheat the resulting steam which is fed to the steam turbines that are thus kept hot and spinning all the time. Of course, they emit all the emissions from use of their fuel all the time. But some of this time they dump heat from their cooling towers instead of generating electricity, and they are then said to be operating “spinning standby.”
One or more power stations can be instantly switched from spinning standby to provide electricity to match an increase to demand for electricity. It is said to be operating “generation” when it is providing electricity. Power stations are switched between spinning standby and generation as demand for electricity changes.
Thus the grid operator manages the system to match supply with demand for electricity by switching power stations between “generation” and “spinning standby.”
Windfarm input to electricity
Windfarms only provide electricity when the wind is strong enough and not too strong. So, they suddenly provide electricity when the wind changes. The grid operator must match this changed supply of electricity to the existing demand for electricity. Of course, the grid operator achieves the match by switching a power station to spinning standby mode. That power station continues to operate in this mode so it can provide electricity when the windfarm stops supplying electricity because the wind has changed again.
Windfarms only force power stations to operate more spinning standby. They provide no useful electricity and make no reduction to emissions from power generation. Indeed, the windfarm is the true source of emissions from a power station operating spinning standby in support of the windfarm.
This is confirmed by Dr. John Etherington, (retired) Lecturer in Ecology at the University of Wales. See his book, The Wind Farm Scam, for sale on Internet. It is also confirmed by independent engineers and scientists, who can speak freely, and by anyone with an open mind willing to use his/her logic: why haven’t all these wind farms reduced CO2 emissions?
If wind farms provide useless electricity that is outrageously expensive, then why politicians from all parties want so much of it? Because in return for the massive subsidies they give to wind and solar profiteers, these are contributing to their electoral campaign funds. It’s all so very simple, really.
Am I the only one to think that way? – Of course not! Most “wind warriors” (anti windfam campaigners) know that; UKIP candidates know that, and refuse to danse to that tune; even a Danish High Court judge knows that (see my previous post on this blog). In a radio interview, conservationist Mark Duchamp exposed this systemic corruption most clearly, and he referred to an article and a book from the US on the subject (1). So if you have doubts, you can review the evidence:
And if you still have doubts, read the mind-gobbling article just published by world-famous investigative journalist James Delingpole. The UK is secretely installing thousands of diesel generators to take the place of wind farms when the wind drops: this will raise the price of electricity to staggering heights, and ruin the country.

Neighbors not happy
Posted on July 10, 2013
Second lie: in Denmark, people are happy with their wind turbines
This is false. Nearly 200 associations of wind farm victims have formed in Denmark, and most are now federated into a larger one:
National Association of Neighbors Fighting Wind turbines.
What is more, Dr Mauri Johansson, specialist in Community & Occupational Medicine in Denmark, warns about the serious health effects of windfarms, and of the collusion of the Danish government with Big Wind. He quotes a retired Danish High Court judge who said: “wind power has thoroughly corrupted the political system.”
Here are a few more quotes from his letter:
“Documents …have shown that already in the late 1980’s there were complaints about the noise, but local as well as central authorities generally refused to investigate, and did not involve medical expertise. This happens also today.
“Despite these complaints for over 20 years, unfortunately no medically based research has ever been conducted in Denmark, even not as a base for “safe” distances and noise limitations. The only research has been engineer-performed noise measurements and calculations. This ignores the human physiological impact of the wind turbine noise, previously shown in research into the impacts of other noise sources. Engineers are not physicians, and therefore cannot assess the impact on human health. Furthermore, those acoustic engineers closely connected with the wind industry have an obvious yet rarely acknowledged financial conflict of interest.
“The ongoing denial of FACTS about the existence of serious sleep and health problems in wind turbine neighbours is unforgiveable. So too is the refusal by authorities to properly measure the noise inside people’s homes, and the refusal to conduct the multidisciplinary medical research.
“The comments made by retired Danish High Court judge Peter Roerdam in the Copenhagen Post on 16th November, 2012 (12) that wind power is “an industry which has thoroughly corrupted the political system” is all too true, in my experience, and comes at the direct expense of the health of Danish people.
“It is clear the institutional political corruption, and the lack of professional ethics on the part of wind industry acousticians and public health researchers, who ignore or deny the existence of the sleep and health problems and the consequent serious longterm damage to health, is not limited to Denmark.”

The first lie: developers consult with the community
Many people who live near wind turbines wake up with palpitations in the middle of the night because of pulsating low frequency noise and infrasound emitted by wind turbines. Then they waste hours trying to get back to sleep. So how come wind farms are built so close to homes? It’s to make more money, for the further out they go into the wilderness, the longer the power lines and the access roads they have to build.
The wind industry argues that their developers consult with the community. This is a half-truth, which is very effective for misleading the public because it contains some apparent truth. The following letter, written by a concerned Irishman to the Irish Times, tells a different story:
Wind farm facts and fictions
Tue, Apr 9, 2013, 05:55
First published: Tue, Apr 9, 2013, 05:55
Sir, – Once again a wind farm developer misses the point when dealing with objections to wind farms (Letters, April 5th). Brendan McGrath, CEO of Gaelectric, writes that responsible wind farm developers consult local communities.
What he doesn’t state is that these consultations only occur once landowners have been locked into contracts to put wind turbines on their land. What follows is a divided community with some farmers set to make thousands of euros a year from turbines on their land, and their neighbours, who are facing a future of noise, visual disturbance and property devaluation.
Responsible developers should be discussing their proposals to put wind turbines into an area before they sign up local landowners. Whole communities should then be able to make an informed decision, with the right to refuse a wind farm, no matter how a land area has been designated.
Mr McGrath suggests he is motivated by a desire to cut greenhouse gases. The hundreds of wind farm objectors that I have met have exactly the same ambitions.
They just want to be able to open their windows to peace and quiet, and get a decent night’s sleep. – Yours, etc,

What the man does not say is that the planning authorities rubberstamp the applications no matter how much the citizens protest. Money is all they care about. The democratic deficit is huge.
“Every man is a moon and has a dark side which is turned towards nobody – you have to slip around behind if you want to see it.”
The same may be said of governments, NGO’s, and large companies.
The wind industry is under such pressure from irate citizens that in Australia it has opened a new webpage to spread half-truths and other propaganda in a bid to discredit its critics. The webpage is called Act on Facts: http://www.actonfacts.org
