Since early on in the development of wind-energy production, concerns have arisen about the potential impacts of turbines to wildlife; these concerns have especially focused on the mortality of birds. Structural changes and improved turbine design have been instrumental in reducing mortality in birds. Despite the improvements to turbines that have resulted in reduced mortality of birds, there is clear evidence that bat mortality at wind turbines is of far greater conservation concern. Larger and taller turbines actually seem to be causing increased fatalities of bats. Numerous research opportunities exist that pertain to issues such as identifying the best and worst placement of sites for turbines; and mitigation strategies that would minimise impacts to wildlife (birds and bats). This book focuses on refereed journal publications and theses about bats and wind-energy development in North America.
