Researchers Amanda S. Adams and David W. Keith examine the physical limits of the energy we can extract from the wind. They also examine the policy questions surrounding huge deployments of wind turbines and whether the costs, both in money and impacts, can be justified.
NOW THEREFORE, BE IT RESOLVED that the Wisconsin Public Service Commission and the State of Wisconsin enact a moratorium to stop the permitting and installation of industrial wind turbines until further studies are done, solutions are found, and the State's wind siting rule (PSC 128) is modified to implement standards that address ultra low frequency sound and infrasound from wind turbines that will protect the health and safety of residents.
This important paper from Harvard examines the how each wind turbine creates behind it a "wind shadow" in which the air has been slowed down by drag on the turbine's blades. This drag interferes with other turbines in the project thus reducing the actual output of the facility. The full report can be accessed by clicking on the link(s) at the bottom of this page.
Academic discussion continues as to whether a fleet of grid-connected wind farms, widely dispersed across a single grid network, can provide a reliable electricity supply. One opinion is that wide geographical dispersion of wind farms provides sufficient smoothing of the intermittent and highly variable output of individual wind farms enabling the wind farm fleet to provide for base load demand. In an examination of the 5-minute time-averaged wind farm operational data for 21 large wind farms connected to the eastern Australian grid - geographically the largest, most widely dispersed, single interconnected grid in the world (AER, ) - this paper challenges that opinion. The conclusion of this paper is provided below. The full paper can be accessed by clicking on the link(s) at the bottom of this page.
The Renewable Energy Foundation published this research paper by Dr Gordon Hughes, Professor of Economics at the University of Edinburgh, on the performance over time of wind farms in the United Kingdom and Denmark. The paper can be downloaded by clicking the link(s) on this page. The UK and Danish data used in the analysis is also available below. The following summarizes the results of the research.
This important document examines the real cost of wind power after factoring in accomodations for wind's variable nature and the need to site projects long distances from load.
Abstract: Green technologies (e.g. wind turbines, solar cells, and biofuels) and initiatives (e.g. efficiency, recycling, and organics) yield distinct unanticipated consequences that can partially or fully offset intended environmental benefits.
This paper examines the contribution of wind power generation to operational CO2 savings or the Irish electricity grid. The Conclusion of the paper is provided below. The full paper can be accessed by clicking on the link at the bottom of this page.
This letter written by Princeton Municipal Light Department's (PMLD) General Manager, Brian Allen, offers a candid assessment of the utility's two-turbine (3.0 MW) project. The turbines have failed to live up to expected production levels. The project has also been plagued by technical problems. Rather than reducing rates for customers, the project lost $1.875 million and will continue to lose $600,000 yearly under current circumstances. Excerpts of the letter are provided below.

WHEREAS wind turbines can negatively affect property values for several miles around them; and
Energy Ventures Analysis (EVA) prepared this critique of the decommissioning estimate of the Green River Wind Farm Phase I a wind energy facilitiy proposed to be built in Lee County, Illinois. The executive summary and recommendations of the estimate are provided below. The full report along with the transcript when EVA experts were cross-examined under oath and the EVA slide presentation can be accessed by clicking the links on this page.
The Department of the Interior's Inspector General conducted a review of BLM's management of land leased for solar and wind projects. The findings of the IG highlighted significant failures of the Bureau related to poor monitoring of projects. Nationally, BLM has more than 30,000 acres currently under wind ROW and more than 31,000 acres under solar ROW. In addition, BLM has identified almost 21 million acres of public lands with wind energy development potential, and more than 20 million acres that have the potential for solar energy development.
A new study from Argonne National Laboratory, part of the US Department of Energy, has found that increasing wind power many not lower grid emissions as much as previously thought. The crux of the problem is wind's intermittency -- turbines generate power only when the wind is blowing. This requires that grid maintain backup systems to provide baseload power during periods of calm. The full report can be accessed by clicking on the link at the bottom of this page.
This policy of the New Hampshire Audubon Policy on Wind Energy Projects was approved by the Board of Trustees on January 24, 2012.
THEREFORE, BE IT RESOLVED that the Brown County Board of Health formally requests temporary emergency financial relocation assistance from the State of Wisconsin for those Brown County families that are suffering adverse health effects and undue hardships caused by the irresponsible placement of industrial wind turbines around their homes and property.
The International Electrotechnical Commission (IEC) standard 61400-1 for the design of wind turbines does not explicitly address site-specific conditions associated with anomalous atmospheric events or conditions. Examples of off-standard atmospheric conditions include thunderstorm downbursts, hurricanes, tornadoes, low-level jets, etc.
A suit filed against the Montana Department of Natural Resources and Conservation (DNRC) challenged the adequacy of the Agency's Environmental Impact Statement for the proposed Coyote Wind energy facility. A portion of the wind energy project would be located on State-owned lands. The court found that there was clear and convincing evidence that the DNRC's decision to issue a lease to Coyote Wind was arbitrary and capricious and not in compliance with the law. The ruling by Judge John C. McKeon can be downloaded by clicking on the link at the bottom of the page.
The Washington State Energy Facility Site Evaluation Council (WA EFSEC) recently recommended approval, with conditions, of 35 turbines as part of the Whistling Ridge wind energy project. Fifty turbines were defined in the original plan submitted to the State. The final adjudicative order can be downloaded through the links at the bottom of the page. Of particular interest, readers are encouraged to reference the concurring opinion filed by the Council's chairman, James Luce, and included in the order. An excerpt of his letter is provided below.
