Scores of protected golden eagles have been dying each year after colliding with the blades of about 5,000 wind turbines along the ridgelines of the Bay Area's Altamont Pass Wind Resource Area, raising troubling questions about the state's push for alternative power sources.
The death count, averaging 67 a year for three decades, worries field biologists because the turbines, which have been providing thousands of homes with emissions-free electricity since the 1980s, lie within a region of rolling grasslands and riparian canyons containing one of the highest densities of nesting golden eagles in the United States.
"It would take 167 pairs of local nesting golden eagles to produce enough young to compensate for their mortality rate related to wind energy production," said field biologist Doug Bell, manager of East Bay Regional Park District's wildlife program. "We only have 60 pairs."
Comments
Environmentalists have persuaded the energy industry and federal authorities — often through litigation — to modify the size, shape and placement of wind turbines. Last year, five local Audubon chapters, the California attorney general's office and Californians for Renewable Energy reached an agreement with NextEra Energy Resources to expedite the replacement of its old wind turbines in the Altamont Pass with new, taller models less likely to harm birds such as golden eagles and burrowing owls that tend to fly low.
The neighboring Buena Vista Wind Energy Project recently replaced 179 aging wind turbines with 38 newer and more powerful 1-megawatt turbines. That repowering effort has reduced fatality rates by 79% for all raptor species and 50% for golden eagles, according to a study by Shawn Smallwood, an expert on raptor ecology in wind farms.
It remains unclear, however, whether such mega-turbines would produce similar results elsewhere, or reduce fatalities among bats.
Nationwide, about 440,000 birds are killed at wind farms each year, according to the Fish and Wildlife Service. The American Wind Energy Assn., an industry lobbying group, points out that far more birds are killed each year by collisions with radio towers, tall buildings, airplanes, vehicles and in encounters with hungry household cats.

Housecats tend to catch fast reproducing species like sparrows, while wind turbines kill large raptors, which breed more slowly and are often on the endangered list.

Some moron at the LA Times writes an article about windmills killing birds in the ALTAMONT PASS, and you stick it up as a news story. Great.
That site is one of the oldest and most notorious, from decades back... it's a badly-chosen site... it has the oldest, and worst-for-birds turbines... small and low and fast-spinning... though they're being replaced, year on year... and the entire global wind industry is having to face down nonsense from Rightwing coal and gas and nuclear interests because of it.
Naturally, you're all over it.
And like your other anti-environmental articles, you seem unaware or uncaring that they tend to come from Rightwing think tanks and be pretty much impervious to facts.
e.g. Efficiency? To you, it's hopeless. Because of the Jevons effect, an effect almost entirely free of empirical results. When I post up a BATCH of refutations and criticisms - and entire damn series of links blowing the hole out of your cruddy link - you're so engaging that you can't be bothered responding, but instead,you put up another blog entirely, just to link to another article on the issue. As a blogger, to post on something, get a response, refuse to respond, but then to just float on by and post up another link? Way to go.
e.g. Your long (long) series of the failures and high cost of electric vehicles and hybrids. And once again, the facts quoted seemed to come down to you had some "gut feel" about things and had some quotes from a local car dealer.
e.g. Inflation. Who's the guy pumping up the volume on a dozen different, and equally indefensible babble-logues about "inflation"? And who seems to have no idea that this is the exact same message that the Rightwing assholes (again) are putting forward to dampen down the possibility of using monetary policy to combat unemployment? Yeah. You know who.
The only stuff you seem to dig is the Doomster shit, with the Druids and Peak Oilers and Suburban crashers all moaning on about how life is doomed. Though when confronted on particulars, you can't debate it.
Against efficiency, against renewables, against cleaner vehicles, against monetary policy to combat unemployment - you're basically a poster child for dim Right Wing propaganda pieces.
So. Housecats catch only some kinds of birds, while wind turbines are baaaaaaaad. Well... wow. I think at this point, I'm just gonna bow out before the depths of knowledge in this debate wet my sandals.
P.S. You actually have the gall to raise this issue, and want to be taken seriously, and yet, you're... AN ARCHITECT. When if there's one profession out there which can absolutely without question be named as killing more birdlife than windmills - and of any and all descriptions - it's yours.
You need to start posting in the comedy corner.

We have whole species that will be wiped out by the impact of seasonal changes on food stuffs of migratory birds. This is happening now.

One of the scientists on Planet Earth, in Borneo, mentioned a similar concept. Clearing the land, and killing the insects, wipes out the base of the food chain.

When spring comes too early, and winter too late, thanks to carbon, the birds arrive right on schedule at the migratory waystops they have frequented for millennia, but suddenly the insects and berries are all on a different timetable, and have come and gone. Talk about angry birds.
I'll take my chances with windmills and, I suppose, even nukes.

Donal, here's a photo essay for you.
Here's a pix of a few whirlly thingys in my neighbourhood.
Here's my car parked about 100 feet or so away. Note the stairs to the hatch door.
Here's looking up at the props. The pix doesn't do them justice ... they look bigger in real time.

I can't correct anything or take out the second duplicate...sorry.
But those blades rotate slowly by our standards. However, I suspect there's tons of rpm generated to turn the pivot point fast enough to generate electircal current.
Perhaps those in California are smaller which may mean they're turning much faster. Economies of sacles would imply the more whirly thingys per acre would generate more power so they've opted for smaller units to cover more area so as to increase output per acre.

They have huge transmissions to gear up the revs. The props themselves don't whirl like helicopters or anything. The bird kills are not from chopping and frappeing, but from collisions. Cell towers are a bigger killer.
by Rootman on Tue, 06/07/2011 - 8:06am
This link cites blade tip speeds from 138 mph to 200 mph, which sounds a lot more dangerous than colliding with a stationary cell tower, though I agree that towers and their guy wires are also a problem.

2.9 bird deaths per turbine per year cited here. "Our hunch is that the Altamont Pass California wind turbines, reportedly the site of some of the highest bird mortalities associated with any US wind farm, and using what is now an antique turbine design, are at the root of the widespread association of bird mortality with wind turbines in general."

Thanks for the link, Rootman. It helps show why I'm so grouchy about this stuff. I mean, the article linked is 5 years old. And even then, it's called "Common Eco-Myth" - not "breaking news story."
The article is basically posted up because even then, the argument was tired, and in particular, the referencing back to Altamont site and old turbine models. We're now another 5 years on, and buddy from the LATimes thinks this is new and useful.
So... I'm just gonna directly quote some bits from your link here (because a lot of people don't follow links!):
It's a given that anytime we post a story on wind power someone is going to comment that "turbines kill birds," suggesting that wind power may therefore be unacceptable. Compared to what? Hitting birds with automobiles (along with turtles, groundhogs, and deer)? Birds caught by feral cats? Birds colliding with buildings or phone towers?...
Our hunch is that the Altamont Pass California wind turbines, reportedly the site of some of the highest bird mortalities associated with any US wind farm, and using what is now an antique turbine design, are at the root of the widespread association of bird mortality with wind turbines in general....
Whether by intent or because older studies are more common, opponents of wind power will have cited bird mortality data from studies done before 2000 and, to make their point, are likely to focus on studies done on wind turbines erected in high exposure situations: e.g. in migratory pathways, at mountain passes, near nesting areas, and so on. Those are the numbers that get quoted at public hearings, published in the media, and that therefore underlie the collective consciousness about wind turbine hazard to birds. Not unlike what happens to people who constantly see fires crashes and shooting on the local news and come to think that what they are seeing is far more common than it really is, it all comes down to a risk communication problem....
In the United States, cars and trucks wipe out millions of birds each year, while 100 million to 1 billion birds collide with windows. ... these non-wind mortalities compare with 2.19 bird deaths per turbine per year. That's a long way from the sum mortality caused by the other sources.

This bladeless turbine is said to have been designed by Tesla eons ago. Interesting.
by we are stardust on Tue, 06/07/2011 - 10:06am
Everything good was designed by Da Vinci, Tesla or Steve Allen.

Specialized bird radar technologies are available now that can monitoring the birds and automatically idle turbines when bird approach (see http://www.detect-inc.com/wind.html). Systems are currently operating successfully at windfarms in the US and Europe.
