The Ontario Environmental Review Tribunal released this decision partially granting an appeal of the Province's decision to approve the White Pines wind energy facility. The panel upheld the appeal because of the risk of serious and irreversible harm to the Little Brown Bat and Blanding’s Turtle. The White Pines wind facility, as proposed, consists of 29 wind turbines with a nameplate capacity of 59.45 megawatts (MW). The Project will be located within the ward of South Marysburgh and a small portion of Athol, Prince Edward County. The background details of the case before the Tribunal are provided below.

Thousands of industrial-scale wind turbines are being built across the world each year to meet the growing demand for sustainable energy. Bats of certain species are dying at wind turbines in unprecedented numbers. Species of bats consistently affected by turbines tend to be those that rely on trees as roosts and most migrate long distances. Although considerable progress has been made in recent years toward better understanding the problem, the causes of bat fatalities at turbines remain unclear. In this synthesis, we review hypothesized causes of bat fatalities at turbines. Hypotheses of cause fall into 2 general categories—proximate and ultimate. Proximate causes explain the direct means by which bats die at turbines and include collision with towers and rotating blades, and barotrauma. Ultimate causes explain why bats come close to turbines and include 3 general types: random collisions, coincidental collisions, and collisions that result from attraction of bats to turbines. The random collision hypothesis posits that interactions between bats and turbines are random events and that fatalities are representative of the bats present at a site. Coincidental hypotheses posit that certain aspects of bat distribution or behavior put them at risk of collision and include aggregation during migration and seasonal increases in flight activity associated with feeding or mating. A surprising number of attraction hypotheses suggest that bats might be attracted to turbines out of curiosity, misperception, or as potential feeding, roosting, flocking, and mating opportunities. Identifying, prioritizing, and testing hypothesized causes of bat collisions with wind turbines are vital steps toward developing practical solutions to the problem.
As the demand for clean energy increases, wind power generating stations are being constructed across Canada.....concerns have been raised about the possible environmental impact of these turbines on birds, especially after endangered raptors were observed being injured and killed after flying into wind turbines in California.
