It should be noted that the Panel’s ability to fully assess the prevalence of adverse health effects was limited by a lack of available data. As a result, the report outlines where more research is required in order to fill knowledge gaps, including for vulnerable populations.
The Panel has 11 main findings that are outlined in the full report. Some findings include:
- The evidence is sufficient to establish a causal relationship between exposure to wind turbine noise and annoyance.
- There is limited evidence to establish a causal relationship between exposure to wind turbine noise and sleep disturbance.
- The evidence suggests a lack of causality between exposure to wind turbine noise and hearing loss.
- For all other health effects considered (fatigue, tinnitus, vertigo, nausea, dizziness, cardiovascular diseases, diabetes, etc.), the evidence was inadequate to come to any conclusion about the presence or absence of a causal relationship with exposure to wind turbine noise.
- Technological development is unlikely to resolve, in the short term, the current issues related to perceived adverse health effects of wind turbine noise.
- Impact assessments and community engagement provide communities with greater knowledge and control over wind energy projects and therefore help limit annoyance.
