Wind Turbines & Noise

Who should influence the wind turbine noise debate
By Stephen E Ambrose

Stephen Ambrose is a Board Certified Member of the Institute of Noise Control Engineers (INCE) with over 35 years’ experience investigating man-made problems in environmental sound and industrial noise control.

I am respectfully writing in response to the letter by Gordon L. Deane; “Misinformation has undue influence in turbine debate” of February 2, 2012 for the SouthCoastToday.com. I have a question; how did he get himself in such an awkward position? His engineers should have foreseen and advised that there would be an adverse public response to wind turbine noise. There are published documents that would have clearly shown neighbors’ seeking relief with appeals for legal action.

My profession as INCE member requires that I honor and obey “Canons of Ethics”. 1) Hold paramount the safety, health and welfare of the public. 2) Provide services only in areas of competence. 3) Issue public statements in an objective and truthful manner. And there are more. These Canons of Ethics are identical to those required by states for licensed professional engineers.

So many public complaints about wind turbines caused me to wonder why my fellow professionals were not following the principal of the first Canon. This apparent omission prompted me to take an active interest in wind turbine noise. Why are so many neighbors complaining about living near industrial wind turbines? Why are government agencies not doing more to protect the public? There should be more professionals seeking answers.

The second Canon requires that I become competent in wind turbine noise. I now have more than two years’ experience investigating wind turbines with another acoustic professional; Robert W. Rand, also an INCE Member. We each have more than 30 years’ experience working in our areas of expertise, and many of those years working in the Boston office for Stone & Webster Engineering. What we learned there working on large power station projects, was to first determine the sensitivity of nearby neighbors to changes to their acoustic environment using published US EPA methods. Then a noise level criterion was developed for the proposed facility and feasibility determined based on cost-effective noise controls. Sometimes the costs were too great or there were no cost-effective solutions.

The third Canon prompted this letter to inform the public with this brief statement. Why have many wind turbine sites produced such visceral noise complaints? Why have my fellow professionals deferred investigating first-hand for themselves: that is to live as or with a neighbor as we have?

We all should view wind turbine neighbors as representatives of the proverbial canary in the mine. Instead, the neighbor is accused of not being truthful, should be ignored and thereby isolated from consideration. However this is not working, complaints are constantly increasing, including the abandonment of homes. People near large wind turbines are so debilitated that they have taken extreme measures to save their well-being.

Why have only a few environmental noise and public health professionals recognized there is a serious noise problem? The wind turbine industry has enlisted like-minded experts from academia and government agencies to support their goals. Their research is confined to only peer-reviewed documents and panel discussions. They have dismissed the obvious. The neighbors continue to ask that their destroyed lives be peer-reviewed. This leads back to the first Canon: Hold paramount the safety, health and welfare of the public. --

EverPower Rebuttal

A FACTUAL RESPONSE TO EVERPOWER ’S FALSE CLAIMS Julia F. Johnson – February 15, 2012 This paper responds to published claims by Everpower that local opposition to wind energy is not based on fact. When someone is trying to sell you something, the old saying “Buyer Beware” should be remembered. In the case of wind energy, this caution is important and appropriate. Because the proposed Buckeye Wind project area is so densely populated, one of the most important areas of concern is loss of property value. Jason Dagger claims there is no impact on property value and he cites a property value study from the Lawrence Berkley Lab as proof. In truth, even the author of the study, Ben Hoen, himself , criticizes the way the wind industry uses the study to mislead landowners. In Hoen’s own words: “You know we are very cautious about what happens close to the turbines. We really don’t know what’s going on there... It’s a dicey situation and complicated, but I think homes t...

Editorial in the Urbana Daily CItizen

http://www.urbanacitizen.com/ news/editorial/5035999/ Turbines-imperiled-by- shifting-political-winds Turbines imperiled by shifting political winds After seven years of development, controversy and exhaustive legal examination, the two wind farms planned for Champaign County might soon be put on the scrap heap because of recent state legislation that discourages their construction. It’s too soon to say for certain because the proposed projects continue to be affected by ambiguity on many fronts, but EverPower’s comments to the Columbus Dispatch on Sunday sounded like the beginning of the end of Buckeye Wind. “It’s clear this development isn’t wanted here … and it gives us less confidence in where Ohio is moving forward,” Michael Speerschneider, EverPower’s chief permitting and public-policy officer, told the Dispatch . “We’ll take that message to heart.” After Gov. John Kasich signed legislation on Friday that stops increases in requirements f...

In Honor of Earth Day: A Guide to Refuting Pro-Turbine Arguments

Below, you'll find an excerpt from a great blog post that deals with everything pro-turbine folks like to claim as a valid argument in favor of industrializing residential communities (as in Champaign County) with a network of 500-foot towers that will send energy (when it is produced at all) out of our county. The whole post is well worth reading. Click HERE  to go to the source and read the entire post. Blight for Naught: Wind Turbines and the Rationalized Desecration of Nature “To those devoid of imagination a blank place on the map is a useless waste; to others, the most valuable part.” – Aldo Leopold  * This mountaintop removal is praised by wind geeks who claim to hate coal mines. Wind projects don’t remove as much material but they prominently industrialize ridges. Early explorers would have seen this as an enemy gauntlet, and modern gut reactions are similar. There should be a penalty for ruining unbroken vistas. Unsettling numbers of e...
