Jim Wiegand: Exposing the wind industry genocide

Eco Report — April 5, 2014

Jim Wiegand has no affiliations with any business, industry, or groups except Save the Eagles International. He receives no funding for any of this from any outside source. His research and articles are his gift to wildlife and an ignorant society.

For those that have the mistaken belief that wind is green, clean, or in some way a noble venture, reality couldn’t be any further from the truth. There is nothing commendable about hiding the slaughter to millions of protected bird and bats each year.

Most of public is unaware of this because at industrial wind farms there is no transparency. With gag orders, high security, and studies being conducted by the industry’s own biologists, the public has no way of really knowing anything. Under these conditions information is filtered and the industry can report what they believe the public will accept.

Rigging Search Area Size

For decades I have been doing research and making astute wildlife observations. I have the expertise to see what others can not and when analyzing this industry’s studies, I see one sided environmental documents.

From my research and analysis I now have several thousand carcass distance records from turbine blade strikes. These records are from the years 1990 -2010 and none were taken from industry studies conducted with grossly undersized search areas. Search areas for these studies ranged from 50-105 meters from towers. The wind turbines I looked at ranged in size from 65 kW up to 1.5 MW.

These carcass distance records are from the Altamont Pass Wind Resource Area, Montezuma Hills Wind Resource Area, Buena Vista wind project, Foote Rim Creek Rim Wind Project, Cedar Ridge Wind Farm, Forward Energy Center, and the Blue Sky Green Field wind project. From these carcass records it can be seen that most carcasses upon impact are launched beyond a turbines blade tip length away from towers. In fact this number is about 60% -70% depending on the study being looked at. This still does not take into consideration that search areas for most of these studies were too small for the size of turbine being studied. Several of the studies even mention this.

The average carcass distance from turbine towers recorded in these studies ranges from about 1 1/2 – 3 times the blade length of these turbines. Many of these turbines were only about 100 feet tall when including blades of about 8.5 meters in length. Hundreds of the other turbines I analyzed were about 300-400 feet at the tip of the rotor sweep.

But the industry has evolved and newer studies do not use larger search areas for their much larger turbines.

For the sake of comparison I will comment on some of the recent mortality studies that have been conducted by Stantec. The Stantec studies are important because in my opinion they represent the worst of the worst that this industry has to offer. In the last few years the average carcass distance reported by Stantec in their mortality studies at Wolfe Island, Kibby Mountain, Laurel Mountain, and Georgia Mountain in the Northeast, is about the same distance that was reported from the smallest 65-100 kw turbines at Altamont. But there are huge differences between the turbines studied by Stantec and these smallest turbines. The turbines they write reports for are 40-50 times larger. They reach 250-350 feet higher into the sky, they have blades that reach out 50 meters or more in all directions, and their deadly blade tip speeds are much faster.

All of these factors are important in mortality studies because they contribute to greater blade impact force, more carcass drift from the higher altitudes, and impact points much further out from turbine towers. In one case the blade tip impact points were as much as 47 meters further away (56 total) from turbine towers. Add into the equation that some of these the turbines are located on ridge lines and the carcasses thrown towards the downward slopes will to drift even further.  Continue reading here…
