Updated Wind Energy Resources

Updated Wind Energy Resources

Next to irrational fear, wind power production now poses the greatest threat to bats, especially in industrialized countries. The full impact of this exponentially growing industry remains largely unmeasured and unreported, but available evidence is alarming. Wind production companies, widely viewed as “green,” have not lived up to their reputation, and too many conservationists have remained silent for far too long. Bat researchers have worked diligently to help wind energy producers become truly green. However, only a small proportion of companies have implemented even the most cost-effective measures. 
As Merlin reports in his updated resource documents, it’s difficult to explain how we can know so much about cost-effective solutions, yet do so little. He suggests it’s time for cooperation among responsible energy producers and leading conservation organizations to simply rank companies on a true green scale and share these rankings with energy investment advisers, providing incentives for progress before it’s too late.

New Publication in Defense of Bats

Read Merlin’s article, Give Bats a Break, in the Spring 2017 edition of Issues in Science and Technology. This report is based on Merlin’s review of thousands of scientific papers and popular media stories. And it is the first to expose how sensational speculation is fostering bad science in a self-perpetuating cycle of misdirected public health funding that threatens the future of bats. This is an issue that we cannot ignore.

Praise for Speaking Up for Neglected Bats – BAT FLASH

Praise for Speaking Up for Neglected Bats

Many thanks to Anthropocene for their timely alert, Wind energy is tough on bats—but it doesn’t have to be that way, by Brandon Keim in their March 15, 2017 issue.

Over the past decade a growing number of peer-reviewed research publications have reported likely-to-be-unsustainable bat kills at wind turbines, also reporting that kills could be reduced by 44-90% by slightly delaying turbine cut-in speeds (the wind speeds at which turbines are activated to begin rotating to produce energy) during the bats’ fall migration.

Merlin Tuttle and Jessica Kern examine bats killed by wind turbines in West Virginia, where Merlin led early efforts to minimize bat kills.

The best available calculations indicate that by implementing these changes, annual power output would be reduced by less than 1%. Yet only a few companies have acted on even these economically feasible recommendations, despite repeated warnings that whole species could be threatened with extinction without prompt action. Keim raises the obvious question, “how people already know so much about solving the problem, yet do so little.” The answer seems obvious—Too many people still don’t know, and too many of us who do have remained silent for too long.

Please take a moment to thank author, Brandon Keim, and the editorial staff at Anthropocene for reminding readers that alarming and growing numbers of ecologically essential bats are being killed needlessly by carelessly operated wind turbines.

Book Review: Conservation and Ecology of Pennsylvania’s Bats

Book Review: Conservation and Ecology of Pennsylvania’s Bats

Conservation and Ecology of Pennsylvania’s Bats, edited by C.M. Butchkoski, D.M. Reeder, G.G. Turner, and H.P. Whidden. 2017, is a publication of the Pennsylvania Academy of Science. Twenty-eight contributors cover a wide variety of conservation-relevant topics. It summarizes the key ecological and economic roles of bats and traces the history of bat research and conservation efforts in Pennsylvania, which has one of America’s finest records of conserving bats.

A Wind Energy Voluntary Cooperation Agreement is reported to have gained beneficial results. However, the environmental review process does not cover most of the state’s species. And at least one of the state’s largest companies has refused to participate. The potentially serious, yet inadequately documented wind energy impacts on bats remain as unresolved threats. (more…)
