Freeborn County will soon be home to another wind farm.

Today, the public service commission of Wisconsin made the unanimous decision to move forward with a project that would bring 122 wind turbines to northwest freeborn county, producing enough energy to power more than 50-thousand homes in Minnesota and Wisconsin.

The bent tree wind farm project has been in the works since 2003.

Now the Wisconsin Power and Light Utility Company is looking to secure a permit in Minnesota to begin construction on the project.

But not everybody is happy.

For most people, the thought of building a wind farm holds the image of all good things...

"This is a good project, this is a green project, we live in a rural community, that has a hard time with fossil fuel and generating power so it seems like a pretty good thing for the county, and the state, and the nation actually," says Wayne Sorenson, planning and zoning director.

The project would not only generate enough renewable energy for 50-thousand homes, it would bring funds to freeborn county.

"Probably 1 point 3 million dollars a year," says Sorenson.

But not everyone is excited.

A local group called safe wind is worried about the health effects of having turbines run so close to their homes.

"I am not against wind energy, but it's not green when it's making people sick," says Katie Troe, the organizer of Safewind.

Residents aren't necessarily worried about the audible noises these turbines create; they're concerned with the low-pitched frequencies humans can't hear that can possibly cause health problems.

Right now the current law says turbines must be built 5-hundred feet away from homes, with an audio level of 50 decibels or less, but Safewind says measuring just the audible noise isn't good enough.

"Safe wind would like to see 15-hundred foot setbacks, and the three weights, the audible noise, the DBC, the low-frequency noise, and the DBG, used for the infrasound," Troe says.

The dBC and dBG levels are low frequency sounds are emitted from wind towers.

Some studies have shown living too close to these frequency's can cause nausea, loss of bowels, vomiting and even organ damage.

"At this point there is really no documented proof in the history of these wind towers that something that far away is really going to have that effect," says Sorenson.

"There is not a lack of information, it's that it's been ignored, or swept under the rug or just not brought to their attention," says Troe.

As of right now the utility has agreed to build the turbines one thousand feet from homes, but Safewind is still trying to receive 15-hundred foot setbacks.
