Wildlife expert Dan Boone presented these slides at the 38th North American Symposium on Bat Research held in Scranton, PA in October 2008. Mr. Boone's presentation focused on the trade-offs of wind energy development in Eastern US balancing the benefits of this energy resource against the environmental risks, particularly to bats. Note that slides # 27, 32 and 33 of the presentation provide graphs which quantitatively estimate the potential impacts on bats and forest habitat resulting from the projected intensity of wind energy development within the eastern US states which comprise the bulk of the Appalachian mountain region. The summary slide from the presentation is listed below. The full presentation can be accessed by clicking on the link at the bottom of this page.

For two decades, the capacity factor of wind power measuring the mean energy delivered by wind turbines has been assumed at 35% of the name plate capacity. Yet, the mean realized value for Europe over the last five years is closer to 21% thus making levelized cost 66% higher than previously thought. We document this discrepancy and offer rationalizations, emphasizing the long term variations of wind speeds. We conclude with the consequences of the capacity factor miscalculation and some policy recommendations. Click on the link below to download the full document.

This motion was filed with the Vermont Public Service Board on Sep 22, the day hearings were to begin for the Deerfield Wind LLC proposal. Deerfield Wind LLC is seeking to erect 15 industrial scale wind turbines in the Green Mountain National Forest. In response, the Vermont Public Service Board ordered that the hearings be rescheduled to December 1, 2008.

The Deerfield Wind Energy facility is the first wind plant to be proposed for US National Forest lands. The Draft Environmental Impact Statement released by the US Forest Service can be accessed by clicking on the link(s) below. Comments will be accepted through until the end of November 2008.

The Vermont Public Service Board has issued an order regarding violation of a 2003 Certificate of Public Good issued to enXco authorizing construction of two wind measurement towers ("met towers") on Lowell Mountain. The CPG required that the towers be removed within five years of the date of the CPG. The order detailing the violation and subsequent agreements is listed below.

This paper documents the results of an in-field test at the Maple Ridge wind energy facility in New York to determine the effectiveness of using an experimental acoustic bat deterrent to reduce bat mortality. The executive summary excerpted below suggests the results were inconclusive. Most bat experts remain unconvinced that acoustic deterrence will be a suitable mitigation approach to reduce bat fatalities at existing turbines.

The Logan County, IL zoning board of adjustment is conducting a public hearing on Horizon Wind's Rail Splitter wind facility. Mr. Len Freeman of Emden, IL presented this testimony before the Board.
