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.
This graphic shows the relationship between the height of turbines and the collision threat to nocturnal migrants at the Chautauqua Windplant, 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.
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…”
In other words, the ad campaign was little more than "greenwashing" -- disinformation intended to present an environmentally responsible public image. BP wanted journalists, politicians, investors and environmentalists to perceive it as a "socially responsible" leader and reward it accordingly. ...Meanwhile, BP's total wind and solar electrical output last year was barely enough to keep the lights burning in Regina, Sask. -- and thoughtful observers began to realize that wind and solar aren't quite as eco-friendly as activists claim.
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.
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.
It's time to jump off the Production Tax Credit treadmill and work toward a more open, transparent support mechanism such as the Electricity Feed Law.
This power point presentation addresses the issues and suggests strategies for achieving changes in local zoning and planning regulations.
"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."
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.
So what are the true contributions of the wind industry? We have electricity that is too expensive to solve any real energy issues, and very little of it besides. We have little, if any, emissions reduction. We have the destruction of pristine landscapes and waterfronts all over the world due to the careless placement of massive, inefficient wind turbines… (a phenomenon that is just beginning to frighteningly snowball here in the U.S), and we have a big money making scheme for those who can afford to cash in. We also have one more thing… the deterioration in the quality of life for those unfortunate enough to find themselves and their neighborhoods targets of the uncaring developers who bully their way into communities and into people’s lives.
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.
Modern windmills, like these near an old-fashioned windmill in Birds Landing, Calif., stand hundreds of feet tall.
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:
