The Cambrons have pointed to issues such as noise and shadow flicker —alternating periods of shadow and light caused by the rotation of wind turbine blades during certain times of the day — as reasons to extend the setback distance for the Vermilion County ordinance.
However, an independent panel study prepared in January 2012 for the Massachusetts Department of Environmental Protection indicated limited scientific evidence to indicate health issues as a result of shadow flicker or the noise produced by wind turbines.
Invenergy LLC, when asked to comment on the problems spoken about at the February county board committee meeting, simply offered this statement: “Invenergy is delighted to own and operate the California Ridge wind project, which generates clean, renewable energy in our home state of Illinois,” according to the statement. “We very much appreciate the community support for the facility, and we’re proud to invest economically in the area through tax payments and job creation.”
The statement also indicated the company’s continuing look at expanding the California Ridge project in the future.
