Wind turbines to produce electricity on a large scale – “wind farms” – are currently being proposed for parts of Tug Hill. Large-scale wind farms are a relatively new occurrence in the Northeast, and since they are new there are many questions that do not have clear answers.
Dear Mr. Boone: I am in receipt of the information you sent regarding the Meyersdale wind project and the risk to bats, specifically Indiana bats in that area and your request for my opinion on this project. I have also done some research on my own concerning wind turbines and its affects on bats, to determine what data are available in the scientific literature in this area. I base this opinion on data and scientific literature, and my 16 years experience studying bat biology and bat ecology.
The Government's thesis that the countryside of upland and coastal Britain is "worth sacrificing to save the planet" is an insult to science, economics and politics. But the greatest insult is to aesthetics. The trouble is that aesthetics has no way of answering back.
Resolving Our Cultural Identity Crisis: Agriculture vs. Environment "...this concept of preserving land in private hands has become a great theme of our region. Our Flint Hills culture has rested on this principle: that we want our land to remain agriculturally productive in private hands, namely producing high quality beef cattle, at the same time we preserve the Flint Hills much as they were hundreds of years ago."
Written by Jonathan Haughton, Douglas Giuffre and John Barrett, this report addresses the prospective impact on the Cape Cod economy of 130 wind turbines in Nantucket Sound. The study includes the responses of tourists and residents to the aesthetics of the proposed project as well as the result of a survey among tourists on the degree to which the project would influence their desire to visit the area. The authors conclude that 'caution' is in order. A follow-up study entitled "Free but Costly" An Economic Analysis of a Wind Farm in Nantucket Sound" was published in March 2004.
This report illustrates how a typical ISO might assess the capacity value of energy sources within an energy portfolio and the negligible capacity value accorded industrial wind. An excerot of the report discussing the limitations of wind is provided below. The full report can be accessed by clicking the links on the page.
"I realize that our ridge tops are not a legally constituted commons in whose future we all have an interest. But wouldn't it be a benefit to the community if they were? After all, they represent a natural legacy left to us by our predecessors in this area, whether by intention or default."
This graphic shows the relationship between the height of turbines and the collision threat to nocturnal migrants at the Chautauqua Windplant, NY, in the Fall of 2003. A companion graphic included in the NWW photo gallery depicts this threat to noctural migrants in the Spring of 2003.

I can’t help but think if it weren’t for Zilkha bursting at the seams with taxpayer money, that this wind turbine controversy bitterly pittting a few large landowners against hundreds of ordinary citizens, would never have happened.
The random intermittency of electrical power supplied from many renewable sources, most notably wind, requires a high level of conventional back-up generating capacity to ensure security of supply. As the penetration of intermittent generators increases and becomes a significant proportion of the total, the extra system requirements and costs could pose serious problems. Although the causes of recent well-publicised blackouts have been due to other reasons, intermittency will exacerbate the potential for cascade failure. Editor's Note This paper complements the Irish Grid and Eon Netz reports that address the low capacity credit of wind power.
This significant research by van den Berg explains why turbine noise as far away as 1900 meters (more than 6,000 feet) is resulting in complaints by residents particularly at night. The paper concludes that noise immission predictions are not accurate and result in the understating of turbine noise levels, particularly during nighttime conditions.
FLEURIEU EAGLES THREATENED - IS ORIGIN ENERGY SERIOUS ABOUT THE ENVIRONMENT? ENVIRONMENTAL LOSS IN THE NAME OF ENVIRONMENTAL GAIN
Journal of Sound and Vibration "Since the start of the operation of a 30MW, 17 turbine wind park, residents living 500m and more from the park have reacted strongly to the noise; residents up to 1900m distance expressed annoyance. To assess actual sound immission, long term measurements (a total of over 400 night hours in 4 months) have been performed at 400 and 1500m from the park. In the original sound assessment a fixed relation between wind speed at reference height (10 m) and hub height (98 m) had been used. However, measurements show that the wind speed at hub height at night is up to 2.6 times higher than expected, causing a higher rotational speed of the wind turbines and consequentially up to 15 dB higher sound levels, relative to the same reference wind speed in daytime. Moreover, especially at high rotational speeds the turbines produce a ‘thumping’, impulsive sound, increasing annoyance further. It is concluded that prediction of noise immission at night from (tall) wind turbines is underestimated when measurement data are used (implicitly) assuming a wind profile valid in daytime."
This image was captured by the Ikonos satellite on September 14, 2003. Turbine access roads branch out from numerous “handles”. The blades of the turbines cast black shadows on the ground.
Typhoon Maemi struck Miyakojima Island on September 11, 2003 with an average wind speed of 38.4m/s and a maximum gust of 74.1m/s, recorded at Miyakojima meteorological station. All six wind turbines operated by Okinawa Electric Power Company were extensively damaged. Two Micon M750/400kW turbines collapsed by the buckling of the towers and one Enercon E40/500kW turbine turned over due to the destruction of the foundation. The other three experienced broken blades and damaged nacelle covers.
...the NYSRC stated that the design of a Renewable Portfolio Standard ("RPS") may have significant impact on the reliability of the New York State bulk power system.....
This Wedge-tailed Eagle was found by a group on a visit to the 23 turbine Starfish Hill wind farm in September 2003. It was taken to a Vet who discovered it had so many broken bones and internal injuries that it had to be put down. Two weeks later a second Wedge-tailed Eagle was killed at the same wind farm. This one was found with its head cut off. A third Wedge-tailed Eagle has since been killed. A Wedge-tailed Eagle was killed at Woolnorth in Tasmania and another at Codrington in the western district. Numerous other birds have been killed at these wind farms. The following link is to a related Eagle Hawk Action Group press release http://www.windaction.org/news/1823
