This graphic shows the relationship between the height of turbines and the collision threat to nocturnal migrants at the Chautauqua Wind Farm, NY, in the Spring of 2003. A companion graphic included in the NWW photo gallery depicts this threat to noctural migrants in the Fall of 2003.
This document prepared by Henry Seifert and others documents the risk of ice shed and ice throw on turbines operating in an area where ice can build up on the blades.
Dr. Richard Truly, Director, National Renewable Energy Laboratory Dear Dr. Truly: It has come to my attention that an employee of the National Renewable Energy Laboratory (NREL), Mr. Larry Flowers: 1. Asserted, during public “forums” on wind energy held on March 25, 2003, in Ludington, Michigan, that I am in some way associated with the coal industry and, therefore, my analysis and writing concerning wind energy should not be considered credible. Over 150 people attended these public forums. 2. On March 27, 2003, distributed via email to one or more participants in the Ludington forums the attached undated, unsigned paper which questions the independence of my work, questions the truthfulness of my claim that my work on wind energy is self-financed, and makes other false and misleading statements. Mr. Flowers’ email forwarding the paper includes the following statement: “MI wind colleagues: here is a brief piece written in response to Glen [sic] Schleede misinformation. I suggest you distribute this to participants in the Ludington meeting…”
Responsive load is the most underutilized reliability resource available to the power system today. It is currently not used at all to provide spinning reserve. Historically there were good reasons for this, but recent technological advances in communications and controls have provided new capabilities and eliminated many of the old obstacles. North American Electric Reliability Council (NERC), Federal Energy Regulatory Commission (FERC), Northeast Power Coordinating Council (NPCC), New York State Reliability Council (NYSRC), and New York Independent System Operator (NYISO) rules are beginning to recognize these changes and are starting to encourage responsive load provision of reliability services. The Carrier ComfortChoice responsive thermostats provide an example of these technological advances. This is a technology aimed at reducing summer peak demand through central control of residential and small commercial air-conditioning loads..........Editor's Note:This paper provides insight into how grids operate.
Michigan mostly has wind resources of class 3 or lower, making wind power production costs high and non cost-competitive vs. conventional fossil power sources.
"This document aims to help developers, planning and enforcement authorities, other government agencies and the broader community assess environmental noise impacts from wind farms. The core objective of these guidelines is to balance the advantage of developing wind energy projects in this State with protecting the amenity of the surrounding community from adverse noise impacts. Wind farms need specific guidelines because wind turbines have unique noise generating characteristics and the environments surrounding wind farm sites usually have low ambient noise."
This power point presentation addresses the issues and suggests strategies for achieving changes in local zoning and planning regulations.
Study Objectives Primary Analysis Questions: 1) Determine effect of wind turbines on residential property values 2) Determine economic impacts to local economy 3) Estimate new tax revenues for Kittitas County from proposed wind farm. This study along with the REPP study are the two most often cited by wind developers to support their claim that industrial windplants do not adversely affect property values.
To help shed light on key issues, this paper focuses on recent and pending “wind farm” developments in West Virginia.
Having had hundreds of queries from park owners, park users and other members of the public concerned about the increasing number of wind farms in the planning pipeline I have put this document together. Please note I have been helping campaign against wind farms for over 10 years so my view are somewhat partisan, however, I urge you to read the following before coming to your own conclusions.
The story reveals that Radnor officials were misled and don’t understand that commercial wind energy is not an environmentally benign source of electricity. The officials are probably not aware of certain facts such as the following:
High annual growth rates over the past years resulted in an installed wind power capacity of 12 000 MW in Germany by the end of 2002 which generated about 17.3 MWh electricity, that is about 3.7 % of the German electricity consumption. This development was made possible by laws introducing feed-in tariffs for wind power generation. Due to the fluctuating nature of wind power generation the feed-in of growing amounts into the grid causes considerable challenges and costs for affected transmission system operators, who have to ensure a save grid operation, though basically good working wind power prediction tools exist. The owner of wind turbines do not have to deal with these problems since the Renewable Energy Act (EEG) ensures that their generated power is compensated for by fixed feed-in tariffs. In the long run, this is not a sustainable approach: Wind power needs to compete sooner or later fully with other power generating technologies at the market and wind turbine owners need to be able to sell a tradable product. After successfully supporting the development of the wind power technology, an approach is needed for including the owners of wind turbines in the task of realizing other ways than simply providing growing amounts of balancing power for wind power feed-in and gradually face them with the energy economic reality of integrating large amounts of wind power into the grid.
ECO-Northwest’s 1-month, $15,000 study, sponsored by the local business lobby organization, the Phoenix Group, has been met with deep skepticism in the Kittitas Valley. Regardless of how people feel about wind farms in this valley, most people recognize this report as simply a blatant endorsement of proposed local wind energy projects, bought and paid for by those behind these projects. A local newspaper story about ECO Northwest’s report titled “Are Wind Farm Benefits Full of Hot Air?” (The Yakima Herald-Republic, 10/2102) reflects this public skepticism about the impartiality of this study. The report makes the incredible claim that property values will not be affected and the unsubstantiated claim that the county will receive millions of dollars in increased revenue. Although the wind energy companies state that they will hire only 22 people, the report manages to inflate this to 53 jobs and claims that these people will somehow result in an additional $4.2m being spent within the county. ECO Northwest’s report also neglects to consider the effect of major wind farms on tourism, one of the most important factors in the local economy. It does not consider alternative locations for such projects, or alternative forms of renewable energy in Kittitas County, or whether the county will benefit from the power generated. Nor does it consider that the proposed location for these wind farms is an area that the city of Ellensburg will need for future expansion of its population, an area that will be closed off for housing if wind farms are built there.

Kelly Alexander believed that windpower would be a good energy source. He was told the machines were not noisy. No one told him about the blade flicker that shines even through closed blinds or the low frequency noise that penetrates his home with doors and windows tightly closed and storm windows installed. Recently, the turbine owner visited Kelly and asked what he could do to help the situation. He said, “Stop lying about these turbines. Tell people the truth.”
Thank you for your enquiry about wind farm noise. I should probably explain my background and interest in wind farms. I have been a noise and acoustic consultant for more than 30 years and most of my current work is dealing with the assessment of environmental noise as it affects residential properties. I work equally for those potentially creating noise and those affected by it. I have been a supporter of wind energy and other forms of renewable energy for some 35 years. I have carried out noise assessments for both “sides” in planning applications for wind farms and adopt the same method of assessment whoever employs me.
I thought it might be helpful for the members of the Town Board, as well as for the residents of the Town of Sardinia, to briefly address a number of frequently asked questions regarding land use moratoria:
