Wind energy development is an environmentally-friendly alternative to greenhouse gas-emitting fossil fuels, but can have negative impacts on wildlife, including bats.  Strategies to minimize mortality of bats at wind energy facilities include siting, curtailment, and development of bat deterrents.  In this seminar, I will outline proposed research to address the issue of bat mortality at coastal and offshore sites in New England.  Proposed research will include investigations of bat use of these habitats during the summer maternity period and fall migration season, as well as development of a model to evaluate economic trade-offs associated with varying curtailment regimes.
