- Wind energy has the lowest lifecycle greenhouse gas emissions compared to other conventional sources.
- In 2015, the 191 million megawatt hours generated by wind energy in the United States avoided an estimated 132 million metric tons of CO2, the equivalent of reducing power sector CO2 emissions by 6 percent, or the equivalent emissions of 28.1 million cars.
- Water: Existing Vermont wind farms have demonstrated that we can generate clean energy and protect clean water.
o Water quality monitoring data from Vermont’s existing wind farms shows that water quality has been maintained post-construction. In some locations, water quality measurements have even demonstrated improved conditions.
- Price: Unlike volatile fossil fuel prices, a long-term contract with a wind project offers a fixed price for electricity. When the wind is blowing in Vermont, it's generating power, which helps keep our electric rates lower than every state in New England except Maine.
- When wind energy is added to the grid, the grid operator is able to reduce the output of the power plant that is currently online. This is almost always the most expensive, fossil fuel burning power plant.
- Vermont’s four existing wind projects (Sheffield, KCW, Georgia, Searsburg) generate enough clean energy to power more than 46,000 households and contribute nearly $1 million to the Vermont Education Fund annually.
Health Canada – Wind Turbine Noise and Health Study
Health Canada – Wind Turbine Noise and Health Study:
Summary of Results http://www.hc-sc.gc.ca/ewh-semt/noise-bruit/turbine-eoliennes/summary-resume-eng.php
The study’s key findings are (http://www.hc-sc.gc.ca/ewh-semt/noise-bruit/turbine-eoliennes/pamphlet-brochure-eng.php):
· “No evidence was found to support a link between exposure to wind turbine noise and any of the self-reported illnesses (such as dizziness, tinnitus, or migraines) and chronic conditions (such as heart disease, high blood pressure, or diabetes).”
· “No association was found between the multiple measures of stress (such as hair cortisol, blood pressure. heart rate, self-reported stress) and exposure to wind turbine noise.”
· “The results of this study do not support an association between wind turbine noise and self-reported or measured sleep quality.”
· “While some people reported some of the health conditions above, their existence was not found to change in relation to exposure to wind turbine noise.”
· “No association was found with any significant changes in reported quality of life, or with overall quality of life and satisfaction with health. This was assessed using the abbreviated version of the World Health Organization's Quality of Life Scale.” MASS DEP Wind Turbine Health Impact Study Among the key findings of the panel were: http://www.mass.gov/eea/docs/dep/energy/wind/turbine-impact-study.pdf
· There is no evidence for a set of health effects, from exposure to wind turbines that can be characterized as “Wind Turbine Syndrome.”
· Claims that infrasound from wind turbines directly impacts the vestibular system have not been demonstrated scientifically. Available evidence shows that the infrasound levels near wind turbines cannot impact the vestibular system. · The strongest epidemiological study suggests that there is not an association between noise from wind turbines and measures of psychological distress or mental health.
· None of the limited epidemiological evidence reviewed suggests an association between noise from wind turbines and pain and stiffness, diabetes, high blood pressure, tinnitus, hearing impairment, cardiovascular disease, and headache/migraine. Wind Turbines and Health: A Critical Review of the Scientific Literature http://journals.lww.com/joem/Fulltext/2014/11000/Wind_Turbines_and_Health__A_Critical_Review_of_the.9.aspx The report concluded:
· Measurements of low-frequency sound, infrasound, tonal sound emission, and amplitude-modulated sound show that infrasound is emitted by wind turbines. The levels of infrasound at customary distances to homes are typically well below audibility thresholds.
· No cohort or case–control studies were located in this updated review of the peer-reviewed literature. Nevertheless, among the cross-sectional studies of better quality, no clear or consistent association is seen between wind turbine noise and any reported disease or other indicator of harm to human health.
· Components of wind turbine sound, including infrasound and low frequency sound, have not been shown to present unique health risks to people living near wind turbines. Australian Medical Association https://ama.com.au/position-statement/wind-farms-and-health-2014 In 2014, the Australian Medical Association issued a statement explaining that it does not support the view that sound from wind turbines causes adverse health effects. Regarding infrasound, the association noted that when infrasound levels near wind farms were measured and compared to other urban and rural environments away from wind farms, the results show that infrasound levels were no greater than those experienced in these other environments.
