Not long after the wind turbines began to spin in March near Gerry Meyer's home, his son Robert, 13, and wife, Cheryl, complained of headaches. They have trouble sleeping, and Cheryl Meyer, 55, sometimes feels a fluttering in her chest. Gerry is sometimes nauseated and hears crackling. The culprit, they say, is the whooshing sound from the five industrial wind turbines near the 6-acre spread where they have lived for 37 years.

Two brothers-in-law, a country road in northwest Missouri, a fistfight ...Surely it's happened before, but probably never over wind energy. ...At the heart of the dispute: Just how healthy is the noise from wind turbines? ...In Rock County, Union Township residents studied medical and scientific research for months before drafting their wind ordinance, which says a setback of at least a half-mile from inhabited structures is needed to avoid health problems. Tom Alisankus, chairman of the committee that drafted the ordinance, said committee members found in their research that the state of Wisconsin had no medical or scientific data to back a model ordinance with a 1,000-foot setback. Proposed legislation that would have allowed the state's Public Service Commission to set statewide siting standards failed to reach a vote before the session ended last month. Doctors in other countries, including Canada, England, France, Australia and New Zealand, have written papers about similar illnesses in people who live near wind farms. ..."Does noise bother people differently? Absolutely," said Smith, the area audiologist. "It can have a very debilitating effect." But, he said, before anyone can conclude that the wind turbines are harmful, a major study must be done.

What constitutes protection of public health and safety for siting and operating 400-foot industrial wind turbines with capacities of 1.65 to 2 megawatts? That question stirred lots of activity and animosity in Calumet County in 2007. ...Among the common themes were unacceptable noise levels that disrupted sleeping and other activities, shadowing and flickering inside residences, health problems and attitude changes in their families, loss of property value, interference with television reception and Internet services, and refusal by wind energy system owner/operators to deal with complaints. Concerns specific to Calumet County included protection of groundwater in a very sensitive geological area, flight corridors for medical helicopters between Chilton and Fox Cities hospitals and sheriff and state patrol microwave relay pathways.

Wind energy has become a divisive issue for Trempealeau County's residents over the past 14 months. The county board will vote Monday on a third draft of a wind ordinance they've been wrestling with since investment group AgWind Energy Partners approached the board in September 2006 with a request to look at three potential sites to build four to six turbines. The proposed ordinance is stricter than the previous two. It would require turbines to be at least a mile from all habitable structures and a half-mile from property lines. Among more than 30 other restrictions is a requirement that the noise from the turbines can't exceed 40 decibels when measured at any residence.

There has been very few wind projects built in the state since 2000, though more are planned in the next 12 to 24 months, said Ed Blume, spokesperson for the nonprofit environmental group RENEW Wisconsin. ...According to Blume, the biggest challenges to increasing wind power in the state are more at the local level. The largest complaints in regard to wind turbines are noise level, moving shadows created by the blades and harm to birds. The state typically requires turbines to be 1,000 feet from homes, with noise levels varying on the speed of the wind and how close a home is to the turbine. Bjurlin said the turbines at the Springfield site are loudest in 18 mile per hour winds, with winds over that amount being louder than the sound of the blades.

CHILTON - Life near wind turbines is hell, a panel told about 500 at a forum Wednesday organized by residents worried that proposed wind farms would affect public health and property values. "The noise produced by turbines is intolerable," Kewaunee County homeowner Mike Washechek said. Washechek has lived about ¼ mile from a wind farm for the last seven years. "My wife thought the dryer was on and there was a tennis shoe in it."
