In previous communications, evidence has been provided regarding the risk of adverse health effects and industrial wind turbines (IWTs). Up to now, the siting of IWTs in Ontario is based on predictive computer modelling. While there is ample evidence regarding adverse health effects, the conduct of human health studies to determine regulations for setbacks and noise levels that protect health is still lacking.

The purpose of this document is to inform authorities and decision makers of new evidence, including articles published in peer reviewed scientific journals which advance knowledge on the topic of adverse health effects of IWTs.

Based on the evidence compiled in this document, no further IWT projects should be approved in proximity to humans until human health studies are conducted to determine setbacks and noise levels that will ensure the health and welfare of all exposed individuals.

Furthermore where there are reports of adverse health and/or noise complaints IWTs should be decommissioned until the human health studies have been conducted to determine regulations for setbacks and noise levels that protect health.

This summary may be used and submitted by other individuals.

No financial compensation has been requested nor received for this summary.

» Conclusion


Based on the best available evidence, the following conclusions can be made:

The Canadian Wind Energy Association–sponsored statements that industrial wind turbines do not pose a risk of adverse health effects in humans are scientifically incorrect.

Experts who have conducted original research and/or published peer-reviewed articles in scientific journals confirm that industrial wind turbines can harm human health if they are not sited properly.

Acknowledged adverse health effects include: annoyance, stress, sleep disturbance, headache, tinnitus, ear pressure, dizziness, vertigo, nausea, visual blurring, tachycardia, irritability, problems with concentration and memory, and panic episodes associated with sensations of internal pulsation or quivering when awake or asleep. Other adverse impacts include reduced well-being, degraded living conditions, and adverse societal and economic impacts. These adverse impacts culminate in expressions of a loss of fairness and social justice.

The above impacts in conclusion 3 represent a serious degradation of health in accordance with commonly accepted definitions of health as defined by the WHO and the Ottawa Charter for Health Promotion.

It is expected that at typical setbacks and with the noise study approach currently being used in Ontario to approve the siting of industrial wind turbines, a nontrivial percentage of exposed individuals will experience serious degradation of health.

Harm to human health can be avoided with science-based regulations based on research conducted on human response to industrial wind turbine exposure.

Experts who have conducted original research and/or published peer-reviewed articles in scientific journals confirm that research is required to establish science-based industrial wind turbine regulations to protect human health.

Until science-based research has been conducted, industrial wind turbines should not be sited in proximity to human habitation.

    You are asking too much of those of us who try to exist in houses surrounded by 18 Industrial Wind Turbines (IWT’s), in our case all jammed within a 3 km radius of a small community of ~ 140 houses.

    It is taking all the physical and mental strength we have just to do the activities of daily living, let alone try to educate those lucky folks who still get to sleep and are not constantly aroused or awakened every night.
