Real impact of wind turbines

I have some very important information for the people of Vermont. It has to do with the industry-wide mortality cover-up that has been taking place across North America. It also illustrates why a wind project moratorium is badly needed in this state.

Recently, for the first time, I looked over their mortality studies conducted for Wolf Island. As many are aware, Wolf Island has received a lot of publicity for the number of birds and bats killed at this site. What I found was that the Wolf Island Mortality studies were designed to find only a fraction of the birds killed by their huge turbines. This information is very important so the public can understand the true character of the wind industry. 

Mortality studies done years ago at Altamont Pass showed that large-bodied carcasses like ducks, hawks and eagles were found at an average distance of 57 meters from much smaller turbines. These turbines had a tower or hub height of 32 meters with a rotor diameter of 33 meters. The huge 2.3 MW turbines at Wolf Island have a tower or hub height of 80 meters with a blade diameter of 101 meters. From these studies, it was shown that the placement of hundreds (of) carcasses found under different-sized turbines, showed an increase in carcass distance from turbines with an increase in the size of the turbines.

By using mathematical formulas derived from these studies, the average distance of a large bird carcass found under the 2.3 MW turbines at Wolf Island would be 101 meters from their towers. This average is far outside the search areas used. The Wolf Island mortality studies used search areas of only 60 and 50 meters. These studies clearly missed most of the carcasses. It also does not account for wandering cripples and wind personal interference.

Everybody needs to understand that the big lie has been the wind industry’s game plan for over 28 years when headless eagles first started falling out of the sky around their turbines. Regardless of how one feels about wind energy, lying about turbine impacts should not be part of the process. It stops the public from making informed decisions.
