The spread of wind turbines into quiet rural areas is leading to increasing complaints that they make more noise than residents were led to believe. While simple annoyance and sleep disturbance are the most common effects, in some cases, nearby residents are reporting health problems that they associate with the presence of the turbines, leading some to move from their homes. Not long after wind turbines began to spin in March near Gerry Meyer’s home in Wisconsin, his son Robert, 13, and wife, Cheryl, complained of headaches. Cheryl also sometimes feels a fluttering in her chest, while Gerry is sometimes nauseated and hears crackling. The nearest turbine is 1,560 feet from Meyer’s house. His dismay over an energy source he once thought was benign has made the retired mailman, 59, an activist. He travels the state warning communities considering wind farms to be wary. “I don’t think anyone should have to put up with this,” says Meyer, who compares the sound to a helicopter or a jet taking off.

Been wondering what’s up with the great “Sonar Kills Whales”/”Everything’s Fine, Just Go Away” rhetorical battle between NRDC and the Navy? As you might suspect, the reality is not nearly so neatly defined as either of them might suggest….and if you’re up for digging into it more deeply, the Acoustic Ecology Institute has just posted an AEI FactCheck that explores three key questions:

• Dead Whales: How Common?
• Behavioral Reactions: Millions of Whales Affected, or Negligible Impact
• Additional Mitigation: Common Sense Precautions or Undermining Sailor Safety?

There’s a fair dose of decoding science and regulatory details in this document, as well as acknowledgment of the underlying unspoken ethical questions that lead to radically different perspectives on the same data.

AEI is a resource/information center for sound-related environmental issues, run by editor/writer Jim Cummings (yup, that’s me…). We’ve some how managed to become friends with top scientists and agency staff, major environmental groups, and even a few folks in the Navy and oil and gas industry. More at http://AEInews.org

Plans for a modest-sized wind farm in rural Wales have been abandoned after one of the developers decided that it would have to be cut in half to meet local noise standards. While energy company E.On had hoped to build a 10 megawatt, 8-turbine wind farm, their analysis showed that only a 5 megawatt project would avoid causing a “noise nuisance” to nearby homes, and they could not justify investing in the smaller project. E.On’s head of new business Danny Shaw said: “We certainly didn’t take this decision lightly but, as a responsible developer, we simply wouldn’t be willing to build a scheme that we thought had the potential to exceed acceptable noise limits.” E.On’s planned partner, Arts Factory, hopes to proceed with the smaller project. Arts Factory chief executive Elwyn James said, “We’re disappointed obviously, although we would be just as cautious as E.On about the possibility of causing noise disturbance.” Source: BBC News. 7/2/08 [READ ARTICLE]

 Todd and Jill Stull of Portage, Pennsylvania have sued the operators of the Allegheny Ridge Wind Farm, alleging that the turbines near their homes create noise in excess of local regulatory limits. Attorney Bradley Tupi, representing the Stulls, alleges in the lawsuit that Gamesa Energy misrepresented to local officials the noise levels from the turbines to get approvals for construction of the wind farm. “They assured the officials in the township in question that the turbines would be quiet.

Calumet County, in eastern Wisonsin, recently faced a dilemma that is increasingly common in rural America: an outside company had appeared in their region, planning to build wind farms and seeking permits. Many local governmental bodies have taken a cursory look at complex reports submitted by companies, taken assurances of “no noise” at face value, and later regretted not learning more. The Calumet County Board of Supervisors took two years to consider the issue, and in March instituted a carefully considered ordinance to govern wind farm development that is exceedingly (perhaps even excessively) weighted toward protection of local residents from noise impacts.

While reports of nearby industrial wind farms causing annoyance with their noise are becoming fairly common, a physician who has been looking at the most severe complaints has coined a phrase: “wind turbine syndrome.” Nina Pierpont, a New York pediatrician who has taught at the Columbia University College of Physicians and Surgeons, has found a consistent cluster of symptoms associated with people living near wind turbines, including sleep problems, headaches that increase in severity, dizziness, nausea, exhaustion, anger and irritability. “A setback of 1.5 miles from homes, schools, hospitals and similar institutes will probably be adequate Read the rest of this entry »

The latest AEI Special Report takes a close look (or, listen) to the growing concerns about noise impacts from wind farms.  While it appears that only about 20% of wind farms trigger noise complaints, it is crucial that wind energy developers take a close look at these, to assure they don’t repeat the same mistakes.

As usual with AEI Special Reports, the Wind Energy Noise Impacts report is designed to offer a comprehensive yet concise “ten-minute version” of the issue, with links to more in-depth source material.  It includes sections on wind turbine noise, current regulation, comments from neighbors disturbed by noise, possible factors in noise complaints (atmospheric effects top the list), emerging technology, and links to industry trade groups, government agencies, and advocacy groups, both pro and con.

New San Diego Commuter Train Quieter Than Many Expected - The new Sprinter commuter train has begun test runs along lines that closely abut many residential areas in North County, CA, near San Diego. First impressions seem positive, with many residents noting the much quieter horns being used as the train approaches the many road crossings: the car-like horn sounds at just 85dB, as compared to standard freight and commuter train horns at 107dB. Tom Kelleher, a spokesman for the transit district, said he always expected the public to find the Sprinter much easier to live with than other passenger trains that traverse North County. “I think people really thought  Read the rest of this entry »
