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.

CAMBRIA, Wis. -- With empty storefronts on the main drag and corn stubble stretching for miles in the surrounding hills, this fading farm town seems like a natural stop for the ethanol express. Not to John Mueller, though. The 54-year-old stay-at-home dad has led a dogged battle to prevent a corn mill from building an ethanol plant up the hill from the village school. Concerned about air pollution, the water supply and the mill's environmental track record, Mr. Mueller and his group, Cambrians for Thoughtful Development, have blitzed the village's 800 residents with fliers, packed public meetings and set up a sophisticated Web site. The mill has fought back with its own publicity campaign and local corn farmers have taken to the streets in tractors to show support. Now, as the mill races to build the $70 million plant, the matter is headed to the federal courthouse in Madison, 40 miles southwest.
