This graphic shows the relationship between the height of turbines and the collision threat to nocturnal migrants at the Chautauqua Windplant, NY, in the Fall of 2003. A companion graphic included in the NWW photo gallery depicts this threat to noctural migrants in the Spring of 2003.
This image was captured by the Ikonos satellite on September 14, 2003. Turbine access roads branch out from numerous “handles”. The blades of the turbines cast black shadows on the ground.
Typhoon Maemi struck Miyakojima Island on September 11, 2003 with an average wind speed of 38.4m/s and a maximum gust of 74.1m/s, recorded at Miyakojima meteorological station. All six wind turbines operated by Okinawa Electric Power Company were extensively damaged. Two Micon M750/400kW turbines collapsed by the buckling of the towers and one Enercon E40/500kW turbine turned over due to the destruction of the foundation. The other three experienced broken blades and damaged nacelle covers.
This Wedge-tailed Eagle was found by a group on a visit to the 23 turbine Starfish Hill wind farm in September 2003. It was taken to a Vet who discovered it had so many broken bones and internal injuries that it had to be put down. Two weeks later a second Wedge-tailed Eagle was killed at the same wind farm. This one was found with its head cut off. A third Wedge-tailed Eagle has since been killed. A Wedge-tailed Eagle was killed at Woolnorth in Tasmania and another at Codrington in the western district. Numerous other birds have been killed at these wind farms. The following link is to a related Eagle Hawk Action Group press release http://www.windaction.org/news/1823

Modern windmills, like these near an old-fashioned windmill in Birds Landing, Calif., stand hundreds of feet tall.
A man walks near a demolished wind turbine in Goldenstedt, nortwestern Germany, Monday Oct. 28, 2002. The 70 meter (230 foot) high turbine fell during the heavy storms that hit Germany.

Site of a portion of the Mountaineer Wind Energy Center in 1997, five years before the start of construction. This is a digital color infrared photograph, which explains the odd coloration. The red areas are the conifer tree species (spruce, pine and hemlock) which are highly reflective of infrared light. The photo was taken during the winter so the brown areas depict the bare deciduous forest, mostly northern hardwoods — maple, birch, cherry, and northern red oak. The green bar at lower left is a 100m [328 foot] scale. This study area was chosen to compare before and after conditions, illustrating the impact of this type of development. Jon Boone's Comments regarding Mountaineer (WV) Before (this image), Mountaineer (WV) After (1), and Mountaineer (WV) After (2). The first two images (i.e. Before and After 1) show the extensive forest-interior habitat that existed before the windplant was constructed and the resulting impacts following construction in late 2002. The third image (i.e. After 2) shows the southern half of the windplant (about 22 turbines) and identifies the boundaries of the study area for the pre- vs. post-construction analysis. It also shows that the study area I chose was fairly representative of the existing habitat conditions at this windplant and gives a better view of the magnitude of the development’s impacts on forest and especially forest-interior habitat. [Forest interior is the type of habitat that exists at more than 100 meters from a clearing. Forest interior is required for the survival of certain species and is the type of habitat most easily destroyed by any form of development.] On the portion of the site that I analyzed, the construction of this wind factory cleared over 42 acres of forest for the string of eight turbines (out of 44) that I analyzed. The extensive fragmentation of habitat resulting from the 50-ft-wide service road and the 5+ acres (average) that were bulldozed to erect each turbine caused the loss of over 150 acres of forest-interior conditions within this once-contiguous forest tract. My estimate is that a complete analysis of the entire project area, including 5.5 miles of ridgetop and 44 turbines, would find a total of nearly 200 acres of forest were cleared and over 750 acres of forest-interior habitat was lost following construction of the Mountaineer wind energy facility.
