correspondence on Bat Kill re. Meyersdale Windplant

Gannon_usfws_letters_1__thumb 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.

A Question of Values: A Flint Hills Rancher Ponders Industrial Wind Development

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."

Blowing in the Wind: Offshore Wind and the Cape Cod Economy

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.

California ISO Five Year Assessment (2004-2008)

California_iso_2003_discounting_of_wind_energy_thumb 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.

Wind Turbines Equal Impoverished Legacy

"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."

Thanks Neighbor

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.

Inquiry Into The Practicalities of Developing Renewable Energy

Practicalities_of_developing_renewable_energy_thumb 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.

Effects of the wind profile at night on wind turbine sound

Gpvandenberg_thumb 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.

Effects of the wind profile at night on wind turbine sound

Effects_of_wind_profile_at_night_on_wind_turbine_sound_thumb 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."

Typhoon Maemi downs wind turbines - Japan

Typhoon-maemi_thumb 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.

Wedge-tailed Eagle Mortality at Starfish Hill

F1000004_-2-_thumb 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
