South Dakota residents fail to get half-mile wind farm setbacks

May 3, 2010

An excellent 3-part series on wind farm development ran this week in the Bismark Tribune. It has a good balance of the excitement and economic benefits that attract farmers to the industry, and well-stated concerns from those who want larger setbacks in order to protect neighbors from noise.  The grey area around health impacts is navigated […]

Wyoming Game and Fish sets moderate wildlife protections around wind farms

April 24, 2010

Wyoming has been at the center of the storm over how much wind farm developers should be subject to limits on development in the name of protecting wildlife habitat, thanks to the hot-button issue of the sage grouse, which has been dancing on the edge of federal endangered species listing for several years. In general, […]

Maine towns keep wind farms at arm’s length as state looks to far offshore sites

March 25, 2010

“As goes Maine, so goes the Nation?”  While this old political truism has faded in recent decades, the State of Maine is currently blazing trails in carefully considered wind power development.  At the local level, small towns continue to pass moratoriums and strict setback standards.  Most recently, Thorndike became the third town to set a […]

NPS research shows human noise limits animal listening area, alerting distance

March 15, 2010

A key research paper from National Park Service and Colorado State scientists has been published in Trends in Ecology and Evolution.  The paper, which got a lot of press when it was first made available online in the fall, introduces two key new metrics for measuring the effects of noise on animals.  The first, “alerting […]

Ontario wind tech and health research chair named–background is solid in tech, weak on health

February 23, 2010

Electrical engineer Siva Sivoththaman has been named to the newly-created Ontario provincial Research Chair in Renewable Energy Technologies and Health.  Local activist groups that have raised concerns about the effects of wind farm noise on neighbors had hoped that this position, created as part of Ontario’s new Green Energy Act, would take the lead in formally […]

Vinalhaven begins month-long “experiment” in reducing noise issues

February 11, 2010

The Fox Islands Electrical Cooperative on Vinalhaven, an island off the coast of Maine, has begun a month-long experiment as a first step in trying to come up with a local solution to noise issues from three wind turbines that began operating in November.  About two dozen people within a half-mile of the turbines have […]

Minnesota PUC grapples with wind farm setbacks

February 3, 2010
