Post-construction mortality surveys at Pennsylvania wind turbines  

Author:  | Pennsylvania, Wildlife

As of June 30, 2010, voluntary surveys by the companies owning 83% of the installed wind power capacity (or 79% of total number of turbines) in Pennsylvania reported an annual average of 24.6 bats, ranging from 6.8 to 42.7 (or 3.2 to 21.5 per megawatt), and 3.9 birds, ranging from 1.7 to 9.8 (or 0.7 to 5.0 per megawatt), killed per turbine.

Extrapolated to all 420 turbines, representing an installed capacity of 748 megawatts – and remembering that these are reports from the companies themselves, not independent or peer-reviewed surveys – that comes to more than 10,300 bats and more than 1,600 birds killed by wind turbines in Pennsylvania last year.
