Most of us are parents on this board. This is a calamity for future generations -- and not in the distant future, but our kids and our kids' kids. The measures that we ultimately have to take are going to be a lot more serious than the current effects of wind turbines.
I've been to Alaska twice. The first time was ten years ago and the second was this year. I badly wanted to take my 8 year old because I was afraid to wait until he became a teen. I am so glad. There was a noticeable difference between the glaciers of ten years ago and today. The glaciers were much smaller.
Small towns in Alaska are depend on the tourist industry. If the ships stop coming to port, the townspeople would pack up and leave. At least that is what the tourguides repeated. I would think that Alaskans would be at the forefront of climate change, but they are not. Mind boggling.

Good post. I like it when people do the research to put data in perspective. Thank you.
Yea the perspective is that those "sources" are agenda driven and will present numbers any way that is favorable to them.
Unimpressed.

Note that the source of most of these numbers is AWEA (the American Wind Energy Association). I think the other point is that the "millions" of birds supposedly killed by windows etc are small, common birds. Windmills are placed at ridge lines and other sources of high wind, which are common areas for large endangered raptors to congregate (and get whacked by turbine blades). If any other source of energy was killing tens of thousands of large birds, they'd be shut down in a heartbeat.
Human-Related Threats to Urban Raptors

Abstract
Annual bird mortality in the United States from anthropogenic sources is estimated at one billion. Urban raptors are affected by many of these factors; however, little is known about the relative frequency and magnitude of sources within and among species. I reviewed 86 published sources on mortality and urban use for the raptors of the United States and Canada. Within the Falconiformes (28 urban species), vehicle collisions and electrocutions were reported for most species (73% and 48%, respectively), and vehicular and window strikes were the leading sources of mortality for 39% and 12% of species, respectively. For the Strigiformes (14 urban species), vehicular (63%) and window (47%) collisions affected most species, and the primary sources of mortality were from vehicles (32%) and electrocution (5%). Window-strike mortality was reported for 45% of urban raptors and represented the leading source of mortality for Sharp-shinned Hawks (Accipiter striatus), Cooper's Hawks (A. cooperii), Merlins (Falco columbarius), and Peregrine Falcons (F. peregrinus). Mortality by electrocutions was also observed for 45% of the species. Collisions with vehicles affected a large proportion of urban and nonurban raptors, both for species that use roadways for various activities (e.g., foraging) and for those that do not use roadways. Overall, the literature suggested that collisions and electrocutions are important sources of mortality for most raptors. Future work should directly assess the consequences of these sources on life history and demography of raptor populations.
Note that the source of most of these numbers is AWEA (the American Wind Energy Association). I think the other point is that the "millions" of birds supposedly killed by windows etc are small, common birds. Windmills are placed at ridge lines and other sources of high wind, which are common areas for large endangered raptors to congregate (and get whacked by turbine blades). If any other source of energy was killing tens of thousands of large birds, they'd be shut down in a heartbeat.

Probably about as bad as recycling.
