The topic of the risk of harm to human health associated with wind energy facilities is controversial and debated worldwide. On March 29, 2017, Carmen Krogh presented at the University of Waterloo which considered some of the research dating back to the early 1980’s. A snapshot of some of the current research available in 2017 was provided. The research is challenged in part by the complexities and numerous variables and knowledge gaps associated with this subject. This presentation explored some of these research challenges and provide an update on the growing body of evidence regarding human health risk factors. Included was the emerging research indicating risks to those working in this field.
Carmen M Krogh is a full time volunteer and published researcher regarding health effects and industrial wind energy facilities and shares information with communities; individuals; federal, provincial and public health authorities, wind energy developers; the industry; and others. She is an author and a co-author of peer reviewed articles and conference papers presented at wind turbine scientific noise conferences. Ms Krogh is a retired pharmacist whose career includes: senior executive positions at a teaching hospital (Director of Pharmacy); a drug information researcher at another teaching hospital; a Director of a professional organization; and a Director (A) at Health Canada (PMRA). She is the former Director of Publications and Editor in Chief of the Compendium of Pharmaceuticals and Specialties (CPS), the book used by physicians, nurses, and health professionals for prescribing information in Canada.
Critique of “Health Nuisances of Land-based Wind Turbines”, Statement by the French National Academy of Medicine issued May 9, 2017
By Nina Pierpont, MD, PhD.
The French National Academy of Medicine has used this document in an attempt to redefine “Wind Turbine Syndrome”:
In summary, the health nuisances seem to be primarily visual (disfigurement of the landscape and its psychosomatic consequences) and to a lesser degree noise (of an intermittent and random character as generated by wind turbines of older generations). Medically, wind turbine syndrome is a complex and subjective entity with several factors contributing to its clinical expression, some related to the wind turbine itself, others to the complainants and to the social, financial, political, and communication environment (p. 14).
To reach this conclusion, the authors first review turbine noise levels and hearing thresholds, concluding that noise levels are low. They then review the following potential mechanisms:
- Outer hair cells (Salt): “The work is not clinical or experimental but theoretical, based on the analysis of electrophysiologic, biomechanical, and acoustic models and data, and its conclusions are conservative.” Mechanism not supported (p. 9).
- Otolith organs (Schomer, Todd, Rand): Conflicts with other studies suggesting that the sensitivity of otolith hair cells to infrasound is too low for this mechanism to be relevant to the production of motion sickness symptoms (pp. 9-10).
- Stimulation of visceral organs (Pierpont): Intensities of infrasound not high enough (p. 10).
- Direct action of noise on sleep: This mechanism is supported with a 1.5 km radius, but not further mentioned in the conclusions (see below) (p. 10).
- Psychological factors: These are supported, including the impact of new technologies, the nocebo effect, individual factors of hearing sensitivity and emotional/psychological fragility, and social and economic factors such as lack of profit sharing and excessive communication of unsupported fears on social media (pp. 10-12).
The authors continue:
- These nuisance factors being identified, the analysis of the medical and scientific literature (more than sixty articles have been published to date on the health effects of wind turbines) does not make it possible to demonstrate that, when wind turbines are properly located, they have a significant impact on health. In other words, no disease or infirmity can be imputed to their functioning.
- The problem, however, is that the definition of health has evolved. According to WHO, this today is defined as “a state of complete physical well-being, mental and social,” not only the absence of illness or infirmity.
- In this sense, we must admit that wind turbine syndrome, though the symptoms are subjective, reflects an existential suffering, a psychological distress, in short a violation of the quality of life, which, however, concerns only a part of the neighboring population (p. 14).
The authors proceed to discuss how to ameliorate the effects of wind power development, assuming (as they do) that wind energy is a political given. They propose extending the setback distance from 500 to 1000 m, while recognizing that this is neither politically feasible nor likely to be effective with larger turbines (p. 17).
They discuss caps on dBA noise levels relative to pre-construction and suggest that post-construction enforcement should be improved (p. 15). They suggest design features that affect airflow over and around the blades or stop the turbines when noise thresholds are exceeded (p. 16).
They recommend better public discussion and profit-sharing:
- In the dual aim of improving the acceptance of wind energy and mitigating its impact health, directly or indirectly, on a part of the population of residents, the workgroup recommends:
- To facilitate dialogue between local residents and farmers [who host turbines] as well as the referral of complaints to the authorities, to ensure that public inquiry is conducted with legal rigor and effectively implemented, and to ensure that residents have more interest in the economic repercussions or spin-off of the projects (p. 18).
My critique of the Academy’s report:
Out-of-date on noise descriptions. Does not use the “wind turbine signature” of pulsatile infrasound/low frequency noise with duration of 4 to 100 msec, which is perceptible at sound pressure levels as low as 60 dB (Punch & James 2016, Cooper 2014).
Never mentions migraine as a clinical entity affecting 18% of women and 6% of men; individual differences are instead treated as a reason to discredit physiologic causation and discredit as psychological frailty the population affected. They cite 4 to 20% affected, saying this is so close to the 10% considered affected by traffic noise in Europe that it is acceptable. This is tantamount to defining a sacrifice population and includes blaming of victims.
All the recommended interventions are either in place, have been tried and are useless, or have been called for for years but require changes in human nature, reducing the recommendations herein to “tuttut, let’s all behave better.”
This document attempts to redefine “wind turbine syndrome” to represent factors which are actually not wind turbine syndrome. Wind turbine syndrome is the reaction of migrainous or motion-sensitive people to wind turbine acoustic emissions, the latter now well defined as sharply pulsatile lowfrequency noise. Wind turbine syndrome is different from hysteria or nocebo, as it occurs in people by surprise, who had no thoughts about the turbines before the turbines were installed and turned on and the symptoms began.
I challenge every member of the French working group and their consultants, listed in the report, who self-identifies as having migraine, motion sensitivity, or balance problems, or their family members, including children with developmental disorders such as autism in which auditory and position/balance processing are distorted, to spend a week in a wind park. This would be simple to accomplish and could lead to a tidy “exposure” experiment without ethical obstacles, as the authors believe that they could not be affected as they do not have the psychological limitations and shortcomings they blithely attribute to affected people and use as an excuse to dismiss them.

Health nuisances of onshore wind turbines
Patrice TRAN BA HUY *
The planned extension of the terrestrial wind energy sector raises an increasing number of complaints from associations of local residents reporting functional disturbances achieving what is known as the “wind turbine syndrome”. The aim of this report was to analyze the real health impact and to propose recommendations that could reduce its potential impact.
If the terrestrial wind does not seem to directly induce organic pathologies, it affects through its noise and especially visual nuisance the quality of life of a part of the residents and thus their “state of complete physical, mental and social well-being “Which today defines the concept of health.
In order to improve the acceptance of the wind and to reduce its direct or indirect health impact, the working group recommends:
– to ensure that during the authorization procedure the public inquiry is carried out with the aim of fully informing the local populations, facilitate consultation between them and the operators, and facilitate referral to the prefect by the complainants ,
– to allow the installation of new wind turbines only in areas where there has been consensus among the population concerned as to their visual impact, given that the increase in their size and their planned extension may alter Sustainably the landscape of the country and to elicit opposition and resentment on the part of the riparian population – and general – with their psychic and somatic consequences.
– to systematize acoustic compliance checks, the periodicity of which must be specified in all authorization orders and not on a case-by-case basis,
– to encourage technological innovations likely to restrict and “bridle” in real time the noise emitted by the wind turbines and to equip the oldest wind turbines,
– to reduce the threshold for triggering emergence measures to 30 dB A outside the dwellings and to 25 inside, (while leaving the wind turbines under the regime of the Classified Installations for the Protection of the Environment) ,
– undertake, as recommended in the previous report, a prospective epidemiological study on health nuisances.

Our Experiment in Environmental Ethics
To the Editor:
Back in the 1960s, Yale psychology professor Stanley Milgram conducted a research experiment whose results shocked the nation.
Participants were told that they were taking on the role of ‘teacher’ in a study of methods to improve learning. An authority figure told the ‘teacher’ to administer increasingly powerful electric shocks to a ‘learner’ in the next room whenever a question was answered incorrectly. There actually were no shocks and the learner was part of the research team, but the ‘teacher’ heard increasing cries of pain with each ‘shock’ administered. Even as the intensity of the shocks approached the maximum of 450 volts, the authority insisted that the shocks should continue – that the anguished screams, the banging on the wall, the pleas about heart conditions, and ultimately the ominous silence from the other room should all be ignored.
It was believed that most people would defy the authority figure once they became aware that the shocks were seriously harming another person. But that was not the case: almost 2/3 of participants continued to obey the authority figure, administering ‘shocks’ until the very end.
I was reminded of the Milgram experiments recently while attending two Public Service Board hearings on new proposed sound limits for industrial wind facilities. Because there have been problems, a lower standard of 35 dBA, (down from 45 dBA) has been proposed. (The World Health Organization recommends 30 dBA.)
Those who live close to Vermont’s existing industrial wind facilities have described a range of symptoms that include sleeplessness, headaches, ringing ears, and nausea. For fifteen months, Shirley Nelson, who lived less than a mile from the Lowell wind project, kept detailed recordings of decibel readings (from a monitor installed at their home by the developer, Green Mountain Power) and the health effects she and her husband were experiencing. Entries from her ‘noise diary’ clearly demonstrate the sustained and cumulative adverse effects of living near the turbines at the previous standards.
The Therrien family, who lived near the turbines in Sheffield, pleaded for years for relief – from the PSB, the wind developer, the town of Sheffield, former governor Shumlin and other state officials – to no avail. Their symptoms? “Disturbed sleep, headaches, tinnitus (ear ringing), sense of quivering or vibration, nervousness, rapid heartbeat, high blood pressure, nausea, difficulty with concentration, memory loss and irritability.”
At the Montpelier hearing, the lawyer who represents the proposed Swanton Wind project told the Board to ignore these symptoms – dismissing them as coming from “complainers” and “outliers” whose testimony was just “anect-data”. Instead, he said, the Board should focus solely on submitted peer-reviewed studies that show no health impacts from proximity to industrial wind facilities
In other words: trust authority; ignore the pleas from the other room; continue administering the shocks.
What about other peer-reviewed studies showing that infrasound from industrial wind turbines does affect human health? And it’s hard to dismiss as mere “anect-data” the fact that deteriorating health forced the Therriens and their two young children to abandon a home they loved.
At the hearings, several residents of Lowell (perhaps believing that new standards would threaten their cash cow) not only implied that their neighbors were lying about the health impacts they’ve experienced, but claimed to live much closer to the turbines – with no ill effects – than they actually do. And the few supporters drummed up by VPIRG and industry promoter Renewable Energy Vermont callously waved off the impacts on humans, wildlife, land and water. Some actually called for raising the noise standard to make it easier on the industry.
Reading from talking points generated by VPIRG, someone commented, “There are only eight families complaining….”
What is the magic number that will elicit empathy from VPIRG? Thirty families? A hundred?
In the Milgram study, the pain the ‘teachers’ believed they were inflicting was justified by the supposed benefit of a better understanding of human learning. In Vermont, the justification from developers is that industrial wind is a ‘clean’ solution to climate change. And there are politicians, ‘environmental’ celebrities and non-profit organizations willing to put on a white coat and hold a clipboard to pose as the ‘authority’ on the industry’s behalf.
But for those who find clear-cutting, blasting, and bulldozing mountain ridgelines, degrading water sources, eliminating wildlife habitat, and killing birds and bats ‘clean’ and ‘green’, take a look at before-and-after photos of entire valleys in China destroyed by the mining of rare earth metals, a critical component in industrial wind turbines. Where there were once thousands of acres of carbon-sequestering grasslands there are now mountains of toxic sludge. Four thousand tons of material must be mined to produce the two tons of metals needed for each 3-megawatt turbine.
Production tax credits, the sale of renewable energy credits, and the requirements of state renewable energy portfolios have made the buildout of industrial ‘renewables’ very profitable for corporations, even when the climate benefits are marginal or non-existent. Utility law professor Kevin Jones at Vermont Law School describes all this as a ‘shell game’ that has actually led to an increase in Vermont’s greenhouse gas emissions.
Clever marketing has induced some of us to engage in moral relativism, ethics without substance, and environmentalism at the cost of its soul. If you find yourself arguing in favor of throwing someone under the bus because your favorite pop-‘environmentalist’ says it’s necessary, ask yourself what you would have done in Milgram’s lab.

Just in case we thought the wind turbines would be ordered to be mitigated or shut down if health problems were noticed in the Huron County Health study – nope that’s not gonna happen. Read the correspondence below and you will realize that it is all just ‘process’, with no action to ‘correct’ on the horizon. Basically more people are just being used as test subjects. That’s it. And that’s flat out unacceptable.

Subject: Ability of MOH to write orders against wind turbines under section 13 of HPPA
One of the issues the University of Waterloo ethics committee asked us to address was the hope residents had that, at some time, the Medical Officer of Health would be able to write an order curtailing or shutting down the wind turbines. We had already stated in the recruitment materials that the study would not generate sufficient evidence to prove wind turbines cause health problems (establishing causality) but the ethics committee questioned whether we were providing enough information on the limits of the Medical Officer of Health’s authority. To address that concern, we have spoken with individuals experienced in interpreting the Health Protection and Promotion Act (HPPA) specifically, sections 11 (investigating health hazards) and 13 (writing orders). They provided us with the attached documents that outline the limits on the MOH’s authority to write orders.
The first document (Pelletier v Northwestern Health Unit) is the proceedings from an Ontario Health Services Appeal and Review Board and the second (Court File 2006-01-04) is a judicial review of the appeal hearing by the Ontario Superior Court of Justice. Essentially, these documents state that when the Legislature places the authority to regulate with one organization, such as municipal councils or the Ministry of the Environment, the courts do not accept that there was an intention to give the same authority to the MOH under section 13 of the HPPA. The rulings were made when the Northwestern Health Unit MOH wrote orders prohibiting exposure to environmental tobacco smoke (second hand smoke) in several bars and restaurants. At the time the orders were written, exposure to environmental tobacco smoke was (and still is) deemed a health hazard.
Since the Legislature assigned the duty to regulate wind turbines to the Ministry of the Environment and not the health units, the courts will not recognize the authority of the MOH under section 13 of the HPPA to write an order curtailing or shutting down the wind turbines.
I will be putting these documents on the health unit website soon, however, I wanted you to have a chance to read them first. The documents are publicly available at

You have to see it to believe it. You have to see it to understand the intrusive severe nature of trespass for residents whose homes are now adjacent to industrial wind turbines. You have to see it to gain an idea of the damaging effects of being exposed to strobing shadow flicker in the most private of places your home.
““As it stands, shadow flicker is annoying and annoyance is a serious health issue under the World Health Organization.”
Wind facilities are NOT good neighbours.
Dashwood couple’s problem with shadow flicker raises ire
White Pines Wind (WPD) proposed to be located on the shores of Lake Ontario in Prince Edward County has been dealt a severe blow by the Environmental Review Tribunal. The decision from the “remedies hearing” dealt with issues surrounding the findings of the Tribunal that serious and irreversible harm to the environment to the endangered Blanding’s Turtles, Little Brown Bat and other species at risk would result from the project’s activities. WPD never the less began land clearing construction in sensitive wetland habitats and continued just days prior to the ruling being rendered.
Removal of 18 of 29 turbines leaves lingering questions if the wind project remains financially viable. The residents of Prince Edward County and world wide can only hope that this is a final and fatal blow to the White Pine Wind that will result in halting the invasion of industrial wind turbine generators.
 Under s. 145.2.1(4)(c) of the EPA, the Tribunal alters the decision of the Director by amending Renewable Energy Approval No. 2344-9R6RWR as follows:
1. Adding the following conditions to the REA:
i. Condition J7.1. The Company shall implement the Mitigation Plan for Operation of the White Pines Energy Project, dated July 21, 2016 prepared by Stantec Consulting Ltd., including:
1. Implement the monitoring and mitigation measures as
outlined in Table 2 of the Mitigation Plan;
2. Adjust cut-in speed to 5.5 m/s between sunset and sunrise
from May 1 to September 30 at all turbines for the operating
life of the Project; and
3. In the event of a mortality of a bat species that is a species
at risk, successively increase the operational mitigation as
detailed in Table 2 of the Mitigation Plan.
ii. Condition L2. Further, the Company shall implement the additional
avoidance and mitigation measures as outlined in the report
“Additional Avoidance and Mitigation Measures to Minimize
Potential Impacts to Blanding’s Turtle (Emydoidea blandingii)”,
prepared by Natural Resources Solutions Inc., dated July 22, 2016,
including implementation of the mitigation measures described in Tables 2-1 to 2-5 and 4-1 of that report.
2. Removing from the REA the turbines proposed to be accessed by upgraded municipal secondary and tertiary road segments and intersections in Blanding’s turtle habitat, as identified in Figure 2.2 of the report “Additional Avoidance and Mitigation Measures to Minimize Potential Impacts to Blanding’s Turtle (Emydoidea blandingii)”, prepared
by Natural Resources Solutions Inc., dated July 22, 2016, specifically Turbines 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28 and 29.

In the present study, the brain’s response towards near- and supra-threshold infrasound (IS) stimulation (sound frequency < 20 Hz) was investigated under resting-state fMRI conditions. The study involved two consecutive sessions. In the first session, 14 healthy participants underwent a hearing threshold—as well as a categorical loudness scaling measurement in which the individual loudness perception for IS was assessed across different sound pressure levels (SPL). In the second session, these participants underwent three resting-state acquisitions, one without auditory stimulation (no-tone), one with a monaurally presented 12-Hz IS tone (near-threshold) and one with a similar tone above the individual hearing threshold corresponding to a ‘medium loud’ hearing sensation (supra-threshold). Data analysis mainly focused on local connectivity measures by means of regional homogeneity (ReHo), but also involved independent component analysis (ICA) to investigate inter-regional connectivity. ReHo analysis revealed significantly higher local connectivity in right superior temporal gyrus (STG) adjacent to primary auditory cortex, in anterior cingulate cortex (ACC) and, when allowing smaller cluster sizes, also in the right amygdala (rAmyg) during the near-threshold, compared to both the supra-threshold and the no-tone condition. Additional independent component analysis (ICA) revealed large-scale changes of functional connectivity, reflected in a stronger activation of the right amygdala (rAmyg) in the opposite contrast (no-tone > near-threshold) as well as the right superior frontal gyrus (rSFG) during the near-threshold condition. In summary, this study is the first to demonstrate that infrasound near the hearing threshold may induce changes of neural activity across several brain regions, some of which are known to be involved in auditory processing, while others are regarded as keyplayers in emotional and autonomic control. These findings thus allow us to speculate on how continuous exposure to (sub-)liminal IS could exert a pathogenic influence on the organism, yet further (especially longitudinal) studies are required in order to substantialize these findings.
Ontario has had years to respond to the knowledge that industrial wind turbines are exceeding noise limits. Regulations that the wind industry lobbied for.
In Huron-Bruce county residents continue to battle government to enforce existing regulations to protect and preserve health from intrusive noise of industrial wind turbines. The document below is just one example of many submitted to Ontario from adversely impacted residents:
The pressure continues to mount on the MOECC (Ministry of Environment and Climate Change). The turbines are emitting noise above regulated limits with tonal qualities. Ontario on their own admission and as on the public record- will use the ‘law’ to enforce protections. Do the right thing.
SHUT DOWN THE TURBINES NOW!
Tests Find Some Huron Bruce Turbines Exceed Noise Regulations
APRIL 12, 2017 4:18PM
The MPP for Huron Bruce has called on the province to shut down all industrial wind turbines that fail to comply with noise regulations.
Lisa Thompson says test results released April 7 indicate that the noise levels of turbines near two Huron Bruce residences exceed Ministry of Environment noise guidelines.
The results also acknowledged the possibility that tonal noises are being produced.
However, instead of agreeing to shut down the turbines, Environment Minister Glen Murray claimed the law is being enforced and complaints are being dealt with quickly.
“It has taken two years get these results. The next round of testing could take at least another year and a half,” says Thompson. “I don’t know what this minister thinks quick means, but suffering for three and a half years before anything gets done doesn’t sound quick to me.”
“The Black and Stachura families as well as other families across Ontario have been suffering for far too long from the impacts of IWTs which were built too close to their homes.” said Thompson. “The Minister needs to acknowledge the test results and once and for all do right by the people of Ontario affected by industrial wind turbines.”
She calls on the Minister to acknowledge the test results, and do the right thing.
