Observation and outlook
Finding
EVERY study agrees to note the large number of complaints from "health
victims" of wind turbines and the reality of their symptoms.
The disorders described are the same all over the world: nausea, dizziness,
anxiety, tinnitus, loss of concentration.
A Health Canada study [1] finds that:
"-A statistical link has been
established between the inconvenience associated with noise from wind turbines
and several self-reported health effects reported by respondents, including
hypertension, migraines, tinnitus, dizziness, results obtained at the PSQI
(Pittsburg Sleep Quality Index) and perceived stress.
-A statistical link has been established between the inconvenience
associated with the noise of wind turbines and the concentrations of cortisol
in the hair (stress marker) as well as the systolic and diastolic blood
pressure. "
Numerous studies have proposed an explanation of the physiological
mechanism causing these symptoms, in particular P. Schomer [2], A. Salt [3] and
M. Alves Pereira [4].
We know, of course, that the psychosomatic character intervenes in all
pathologies, which can only exacerbate the cumulative effect linked to the
permanent exposure of people living near wind turbines to their light flashes,
to the obsessive rotation of the rotor, to their solidian vibrations, as well
as to the qualitative impairment of the living environment and real estate
heritage.
On the other hand, several studies have objectified the health consequences
of the exposure of animals to wind turbines. In particular geese [5] and pigs
[6] depending on the distance from their farming to the machines. The proximity
of wind turbines has been indicted in connection with health scandals for
horses in Portugal, for mink, in Denmark and for several cattle farms,
especially in France.
However, although the National Academy of Medicine noted, in its last
report, an attack on the quality of sleep within a radius of 1500 meters from
wind turbines, which it recognizes, as a consequence, as altering health, its
opinion, like that of ANSES, only objects to the insufficient quality of the
level of evidence of the causal link between wind turbines and symptoms
described by residents.
They evoke the responsibility for a “nocebo effect”, a harmful inverse to
the “placebo effect”, which would result from the fear of local residents to be
affected by wind turbines, from their opposition in principle to renewable
energies, as well as to alarming studies on the subject
disseminated on the web by opponents of wind turbines.
This obvious denial of the reality of the problem, which is constant in
every health case, has notably sparked an accusatory report by epidemiologist
Carl V. Phillips *, after he had fought against the same biases in his fight
against tobacco.
In his report “Properly Interpreting the Epidemiologic Evidence About
the Health Effects of Industrial Wind Turbines on Nearby Residents” He
denounces: "There is overwhelming evidence that wind turbines cause
serious health problems among local residents, in a significant proportion and
whose origin is generally linked to stress. Evidence of this is in thousands of
reports. " He considers that “Attempts to deny this evidence cannot be
considered as an honest scientific disagreement but represent either crass
incompetence or intentional bias. " Ironically, in an attempt to refute
the work of Mrs. Alves Pereira that she had sent to ANSES [PJ], this
organization evokes, in its last report [7], a study by the team itself that
coordinates Mrs. Alves Pereira and whose conclusions, on the contrary,
explicitly reinforce his previous work. Indeed, this study precisely highlights
the role of the combination of low frequencies and vibrations, specific to the
"Vibro Acoustic Disease" on which Mrs. Alves Pereira has been working
for 30 years and on which she was led to incriminate wind turbines.
On the other hand, the scientific literature on the subject agrees to
consider that at equal power, wind noise is among the most disturbing. This
characteristic, recognized in particular in the AFSSET 2008 report, is
illustrated by the graph below extracted from E.Pedersen
And this notably because of the importance of the low frequency
components of the wind noise, highlighted by many authors like J. Punch which
shows in particular the correlation between the progressive increase in the
power of the machines and the lowering of the mean frequency of their sound
spectrum.
But also because of its impulsive nature, its great variability and the
aggravating circumstance that it emerges most of the time in a silent
environment.
This can only raise questions about the conditions under which the wind
turbines were exempt from the public health code, while the text put in
consultation with the state services provided for its strict compliance less
than a month before the signing of the decree of August 26, 2011 which
dispenses them.
The ICPE classification which accompanies this decree cannot be the
reason since wind turbines are explicitly excluded from the ICPE acoustic
regime [8], contrary to the answer that was given to Senator AC Loisier
following her question to Government on this subject [9]. The amendment
defended in particular by Mr. Bal for the renewable energy union during the
meeting of August 8 of the Superior Council of Energy (PJ) and which claims
this derogation by raising the ambient noise threshold by 5 dBA wind turbines
can be held liable, raises questions in terms of public health. This threshold
is indeed 30 dBA in the public health code, and therefore, now 35 dBA for wind
turbines. On the other hand, the passage of the blades in front of the mast
results in a significant amplitude modulation of the wind noise. Following the
voluminous report of a group of experts presented by MP Chris Heaton Harris,
[10] the British government recognized its particularly disturbing nature and
undertook work aimed at reforming the regulations. Conversely, the French
professional sector encourages the idea of the emergence of wind noise to be
replaced by that of a "statistical emergence indicator" which aims to
eliminate instantaneous sound peaks. This is how work on the draft measurement
standard Pr NF 31-114, which nevertheless appears in the decree framing wind
noise (August 26, 2011) was suspended for lack of consensus between the various
experts responsible for its redaction, and this should be replaced by a Measurement
Guide drawn up by CEREMA, a public administrative body, in particular engaged
in the promotion of renewable energies. [11]
Finally, the control of spectral emergences at low frequencies (compulsory
in the public health code) has disappeared from the regulatory obligations for
measuring wind noise, despite the particularly sensitive nature of these
emergences
Prospective
Basic protection for local residents should now require:
1 That the problem be quantified, as repeatedly demanded by the Academy of
Medicine and the ANSES, by implementing an epidemiological study.
Because noise, with more than 10,000 premature deaths per year, is
considered the 2nd environmental health cause. (European Environment Agency,
report 10/2014, p 5).
These premature deaths are linked to stress and poor sleep quality.
Those linked to stress caused by wind noise can no longer be concealed by
the evocation of a "nocebo" effect for which residents of wind
turbines are themselves responsible.
2 That an instantaneous emergence control method be implemented and that
the inevitable measurement uncertainties be not systematically paid to the
operator's credit, as is currently the case.
Because it is indeed logical to sanction the operator only in the case of
certainty that the regulatory values are exceeded, risk management should not
allow to endanger the health of residents in the case of uncertainty.
This control method should make it possible to verify that the regulatory
values are not effectively exceeded, contrary to current practices which are
more akin to a statistical method intended to optimize the acoustic clamping
plans, but cause various sound peaks to disappear on average, while they can interrupt
sleep.
3 The return to the strict protection of the public health code, for those
living near wind turbines, implying the return of control of the spectral
emergence of these machines, as well as the return to the threshold of 30 dBA
of ambient noise from which the excessive emergence of wind noise can be
characterized.
4 The implementation of a multidisciplinary and independent scientific
commission, responsible for improving knowledge relating to the various
characteristics of chronic exposure to industrial wind turbines.
And in particular in the fields of psychoacoustics, very low frequencies
and infrasound, vibrations, amplitude modulation, the cumulative nature of
these criteria and the duration of exposure.
5 Pending the conclusions of this commission, a precautionary distance of 2
km between wind turbines and homes is established, as proposed by the Polish
Institute of Public Health [12] after studying 487 publications on the subject
[13].
Or 10 times the height of the machines, as in Bavaria.
6 No repowering operation will be authorized without a new impact study.
For the reason that the increase in the electric power of machines is
generally accompanied by that of their acoustic power (up to 107 dBA for 3 MW
against 104 dBA for most of 2 MW), but also due to a lowering of the mean
frequency of their sound spectrum linked to the lower speed of rotation.
This reduction is described as more impacting for residents by numerous
studies. [14]
