ACOUSTIC TRAUMA:

HOW WIND FARMS MAKE YOU SICK

By Andrew Orlowski

Industrial wind installations are creating a serious health issue, and comprehensive research is urgently needed, says a former Professor of Public Health.

“There has been no policy analysis that justifies imposing these effects on local residents. The attempts to deny the evidence cannot be seen as honest scientific disagreement, and represent either gross incompetence or intentional bias,” writes Carl Phillips, formerly Professor of Public Health at University of Alberta, now an independent researcher.

“There is ample evidence that turbines cause a constellation of health problems, and attempts to deny this involve claims that are contrary to proper methods of scientific inference,” Phillips writes in a paper published in the Bulletin of Science, Technology, and Society. It’s one of several interesting papers in the journal, which is devoted to wind health issues.

Industrial wind installations produce audible and non-audible noise, and optical flicker. But campaigners are fragmented, and face a daunting alliance of big eco-business and government. The academic establishment, which is quick to leap upon public health issues, is strangely inert.

“There is a huge amount of evidence, and it’s incredibly convincing,” Phillips told us by phone, “but it takes a different form to what industry consultants present.”

Empirical studies are rare. Renewable UK, the wind and wave industry lobby group, cites research by the Noise Working Group for the UK business department on its web page devoted to noise issues. The 1996 study, known as ETSU-R-97 (10-page PDF/1.8MB), recommended “Noise from the wind farm should be limited to 5dB(A) above background for both day-time and night-time”, and in the Renewable UK portrait, wind farms sound idyllic; like nature, only more so.

“Outside the nearest houses, which are at least 300 metres away, and more often further, the sound of a wind turbine generating electricity is likely to be about the same level as noise from a flowing stream about 50-100 metres away or the noise of leaves rustling in a gentle breeze,” the group writes.

Yet the ancient study, completed in 1996 and now so old it’s actually in the national archive – has been heavily criticised. Sleep expert Dr Christopher Hanning has written:

“Its major flaws include the use of averaged noise levels over too long a time period and using a best fit curve, thus ignoring the louder transient noise of AM which causes awakenings and arousals. It ignores also the property of low frequency noise to be audible over greater distances than higher frequency noise. By concentrating on sound pressure alone, it ignores the increased annoyance of particular noises, especially that associated with AM. It is also the only guidance anywhere in the world which permits a higher sound level at night than during the day, completely contrary to common sense, noise pollution legislation and WHO guidelines.”

Reality bites blows…

People living near wind farms – and near can be quite a long way away – find the reality far different to Renewable UK’s pastoral idyll.

Dr Michael M Nissenbaum, a radiologist at Northern Maine Medical Center, has new work imminent on the study. He says “significant risk of adverse health effects is likely to occur in a significant subset of people out to at least 2,000 meters away from an industrial wind turbine installation. These health concerns include: sleep disturbance and psychological stress.”

He continues: “Our current knowledge indicates that there are substantial health risks from the existing exposure, and we do not know how to reduce those risks other than by keeping turbines several kilometers away from homes.”

Consultant Mike Stigwood, who has testified before public enquiries, points out that since ETSU-R-97 was published, the World Health Organization has twice lowered its recommended limits for night-time noise.

Currently there’s no solution other than to site the wind turbines further away. But how far?

The Planning Policy Statement on Renewable Energy (PPS22) is often cited here, obliging local planning authorities to “ensure that renewable energy developments have been located and designed in such a way to minimise increases in ambient noise levels.” It doesn’t specify a distance, though.

Hanning notes that: “Proposals that site wind turbines within 1.5km of habitation will not keep wind turbine noise to an acceptable level and are therefore in contravention of PPS22.”

Even at 2km, there are noticeable health consequences.

But there are signs the mood has shifted from one of acquiescence to Big Eco-business – with local authorities judging that they’re accountable to the communities they’re supposed to serve. In June, Highland Council temporarily shut down a 23-turbine installation in Sutherland after persistent complaints by residents. The operator, SSE, had failed to test noise levels at properties 2km away and failed to produce a noise mitigation plan. The stop notice has since been lifted. More are planned nearby.

FEDERAL OFFICIALS INVESTIGATE EAGLE DEATHS AT DWP WIND FARM

SOURCE: Los Angeles Times, www.latimes.com

August 3, 2011

By Louis Sahagun

Pine Tree facility in the Tehachapi Mountains faces scrutiny over the deaths of at least six golden eagles, which are protected under federal law. Prosecution would be a major blow to the booming industry.

Federal authorities are investigating the deaths of at least six golden eagles at the Los Angeles Department of Water and Power’s Pine Tree Wind Project in the Tehachapi Mountains, the U.S. Fish and Wildlife Service said Tuesday.

So far, no wind-energy company has been prosecuted by federal wildlife authorities in connection with the death of birds protected by the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act. A prosecution in the Pine Tree case could cause some rethinking and redesigning of this booming alternative energy source. Facilities elsewhere also have been under scrutiny, according to a federal official familiar with the investigations.

“Wind farms have been killing birds for decades and law enforcement has done nothing about it, so this investigation is long overdue,” said Shawn Smallwood, an expert on raptor ecology and wind farms. “It’s going to ruffle wind industry feathers across the country.”

Wildlife Service spokeswoman Lois Grunwald declined to comment on what she described as “an ongoing law enforcement investigation regarding Pine Tree.”

Joe Ramallo, a DWP spokesman, said, “We are very concerned about golden eagle mortalities that have occurred at Pine Tree. We have been working cooperatively and collaboratively with the U.S. Fish and Wildlife Service and the California Department of Fish and Game to investigate these incidents.

“We have also actively and promptly self-reported raptor mortalities to both authorities,” he said. “Moving forward, we will be ramping up further our extensive field monitoring and will work with the agencies to develop an eagle conservation plan as part of more proactive efforts to monitor avian activities in the Pine Tree area.”

An internal DWP bird and bat mortality report for the year ending June 2010 indicated that compared to 45 other wind facilities nationwide, bird fatality rates were “relatively high” at Pine Tree, which has 90 towers generating 120 megawatts on 8,000 acres.

Golden eagles weigh about 14 pounds and stand up to 40 inches tall. Their flight behavior and size make it difficult for them to maneuver through forests of wind turbine blades spinning as fast as 200 mph — especially when they are distracted by the sight of prey such as squirrels and rabbits.

DWP officials acknowledged that at least six golden eagles have been struck dead by wind turbine blades at the two-year-old Kern County facility, about 100 miles north of Los Angeles, which was designed to contribute to the city’s renewable energy goal of 35% by 2020.

Although the total deaths at Pine Tree pale in comparison with the 67 golden eagles that die each year in Northern California’s Altamont Pass Wind Resource Area, the annual death rate per turbine is three times higher at the DWP facility. The Altamont Pass facility has 5,000 wind turbines — 55 times as many as Pine Tree.

Nationwide, about 440,000 birds are killed at wind farms each year, according to the Wildlife Service. The American Wind Energy Assn., an industry lobbying group, points out that far more birds are killed by collisions with radio towers, tall buildings, airplanes and vehicles, and encounters with household cats.

Attorney Allan Marks, who specializes in renewable energy projects, called the Pine Tree deaths “an isolated case. If their golden eagle mortality rate is above average, it means the industry as a whole is in compliance.”

About 1,595 birds, mostly migratory songbirds and medium-sized species such as California quail and western meadowlark, die each year at Pine Tree, according to the bird mortality report prepared for the DWP last year by Ojai-based BioResource Consultants.

BioResource spokesman Peter Cantle suggested that those bird deaths may be unrelated to Pine Tree’s wind turbines.

“It’s hard to tease out those numbers,” he said. “Basically, we walked around the site to find bird mortalities, which could have been attributable to a number of things including natural mortality and predators.”

The death count worries environmentalists because the $425-million Pine Tree facility is in a region viewed as a burgeoning hot spot for wind energy production.

“We believe this problem must be dealt with immediately because Pine Tree is only one of several industrial energy developments proposed for that area over the next five to 10 years,” said Los Angeles Audubon President Travis Longcore. “Combined, they have the potential to wipe this large, long-lived species out of the sky.”

NOTE FROM THE BPWI RESEARCH NERD: The wind turbine related bat kill rates mentioned in the piece below are alarming and newsworthy. What's more alarming and newsworthy is that the bat kill rates in Wisconsin are nearly twice as high. As far as we know, environmental groups in our state have said  nothing about it.

TRANSALTA URGED TO SHUT DOWN WIND FARM DURING MIGRATION SEASON

SOURCE The Globe and Mail, www.theglobeandmail.com

August 2, 2011

Richard Blackwell

A major conservation group is calling on TransAlta Corp. TA-T to periodically turn off turbines at its Wolfe Island wind farm in Ontario to cut down on the number of birds and bats killed by the machines.

Nature Canada says the project’s 86 turbines are among the most destructive of wildlife in North America. The organization argues TransAlta should shut down parts of the wind farm – one of the biggest in the country – during high-risk periods in the late summer and early fall, when swallows congregate in the region and bats migrate.

“That period is when the vast majority of birds seem to be killed,” said Ted Cheskey, manager of bird conservation programs at Nature Canada. “The evidence is there, and now there is an obligation for [TransAlta] to act.”

The controversy over bird deaths is just one of the many challenges facing Canada’s wind industry, which has run up against by increasingly vocal opponents who say turbines are ugly, cause health problems, and do not contribute to reduced carbon emissions.

The Wolfe Island site, near Kingston, Ont., began generating power in 2009, and an ongoing count of bird and bat deaths has been conducted by a consulting firm since then. Nature Canada says that while bird deaths have been in line with other wind farms on the continent, those numbers are far too high.

The bird death rates from the turbines “are consistently high,” Mr. Cheskey said. He is particularly concerned with the deaths of tree swallows and purple martins – which are in decline in the province – along with bat fatalities.

Mr. Cheskey said his comparison of the numbers in the Wolfe Island report shows the turbines generate one of the highest rates of casualties – about 1,500 birds and 3,800 bats in a year – of any wind farm.

But TransAlta disagrees with Nature Canada’s views. The numbers suggest that the Wolfe Island wind farm is no worse that most others, and is well within limits set by federal environmental regulators, said Glen Whelan, TransAlta’s manager of public affairs.

“The mortality rates that we are seeing in birds and bats are within ranges reported for other wind farms across North America,” he said. For bats, the death rate is well below what is often reported in the eastern United States, he added.

While “bird and bat mortality is unfortunately inevitable at wind power facilities, we are seeing numbers that are within the ranges that are called for by regulators,” Mr. Whelan said.

TransAlta is researching ways to mitigate bat deaths, possibly by turning off turbines at certain times, but the results are not in yet, he said.

Nature Canada is not opposed to wind farms in principle, but it thinks they should be in locations where birds and bats are not at serious risk. Because of its location on a migratory route at the eastern end of Lake Ontario, Wolfe Island is one of many spots where the risk of killing migrating birds and bats is particularly high, Mr. Cheskey said.

Other groups base their opposition to wind farms on other factors. Wind Concerns Ontario, one of the most vocal of the anti-wind groups, claims that noise and vibration from turbines causes sleep deprivation, headaches and high blood pressure. It is demanding independent studies of health impacts.

Anti-wind groups were outraged by a decision two weeks ago from Ontario’s Environmental Review Tribunal which ruled that a wind farm near Chatham, Ont., being developed by Suncor Energy Inc. can go ahead because opponents – who made detailed presentations at a lengthy hearing – did not prove that it would cause serious harm to human health.

Some groups also worry about the aesthetic issues that arise from the erection of thousands of new turbines across the country, while others suggest wind power is expensive, unreliable and needs fossil-fuel-generated back-up.

DEAD CORPORATION WALKING: When Jeffrey Skilling's predecessor at Enron left the company,  employees made what was supposed to be a funny skit about him. In this video, the real Jeff Skilling jokes about moving to "HFV" or Hypothetical Future Value Accounting. "If we do that," he says, "We can add a kazillion dollars to the bottom line."

Enron is credited with jump-starting the US wind industry by pressing for state renewable energy standards, production tax credits, carbon credits and other subsidies.

The wind farm in Monfort, Wisconsin was an Enron project. The turbines still say 'Enron' on the nacelles. Florida Power and Light picked up a lot of Enron's wind assets after the collapse of the corporation. They've since changed their name to NextEra (not 'NextEnron') and continue to develop projects in Wisconsin, most recently making inquiries regarding putting up a met tower in the Rock County Town of Spring Valley.

WIND POWER VS WHOOPING CRANE ON THE PRAIRIE

SOURCE Earth Techling, www.earthtechling.com

June 20 2011

by Pete Danko,

The term of art is incidental take. It refers to the “harassment, harm, pursuit, hunting, shooting, wounding, killing, trapping, capture, or collection of any threatened or endangered species.” Incidental take is in the news now because the Obama administration has given notice that it is evaluating issuing an incidental take permit (ITP) – a free pass of sorts – in a 200-mile-wide corridor from Canada to the Gulf of Mexico where whooping cranes migrate.

The U.S. Fish and Wildlife Service said it was acting at the urging of a collection of wind-power developers – including familiar names like Duke, Acciona, Iberdrola and NextEra – under the banner of the “Wind Energy Whooping Crane Action Group.” The service said an ITP, if issued, would “cover regional-level construction, operation, and maintenance associated with multiple commercial wind energy facilities” in portions of nine states, including Montana, North Dakota, South Dakota, Nebraska, Kansas, Colorado, Oklahoma, New Mexico and Texas.

To obtain an ITP, the government said, an applicant must submit “a Habitat Conservation Plan (HCP) containing measures which would minimize incidental take to any species protected by the ESA, including avoidance of incidental take, and mitigate the effects of any incidental take to the maximum extent practicable; and ensure that the taking is incidental to, and not the purpose of, an otherwise lawful activity. If the Service determines that an applicant has satisfied all permitting criteria and other statutory requirements, the ITP is issued.”

The government said the species affected could include the endangered interior least tern and endangered piping plover, as well as the lesser prairie-chicken, a candidate for listing under the Endangered Species Act (ESA). But it’s a population of whooping cranes that would also be covered by the ITP – Grus Americana, the tallest North American bird – that is drawing the most attention.

According to a 2009 government report, the Aransas-Wood Buffalo Population (AWBP) of cranes, the species’ only self-sustaining flock left on Earth, has been making a slow comeback, but still numbers just 247 individuals. So precarious is the AWBP population, the report said, that a rise in mortality rate of a mere three percent annually – as few as eight additional bird deaths each year – would reverse its comeback and spell doom for the species. For its part, the wind industry said it neither wants to nor expects to diminish the whooping crane’s long-term prospects, but rather it seeks to “streamline the ESA permitting process, allowing for the compatible goals of effective wildlife conservation and robust wind energy development.”

The public has until October 12 to comment on the proposed action (see http://www.fws.gov/southwest/ to download a copy of the notice).

WIND DEVELOPERS VS BIRDS

American Bird Conservancy, www.abcbirds.org 20 July 2011

(Washington, D.C., July 20, 2011) American Bird Conservancy (ABC)—the nation’s leading bird conservation organization—today raised concerns about new draft Department of the Interior (DOI) guidelines for wind development that appear to have been overly influenced by energy industry lawyers and lobbyists. The new draft reverses agency protection recommendations for many bird species and adds unrealistic deadlines that would lead to “rubber-stamping” of wind projects. ABC expects millions of migratory birds to be harmed by poorly-planned wind energy.

The draft guidelines were released ahead of a Wind Federal Advisory Committee meeting scheduled for today and tomorrow in Arlington, Virginia, where Secretary of the Interior Ken Salazar is expected to speak.

“What is particularly surprising is that even the original guidelines proposed by Interior weren’t mandatory. Here, industry is asking for voluntary guidelines to be weakened. What they might succeed in getting, though, is a set of guidelines that lack clarity, plus greater likelihood of legal problems,” said Mike Parr, Vice President of ABC.

“What we are talking about is thousands of unpermitted wind farms that break bird protection laws and open up legal liability for wind developers and risk for investors. Mandatory guidelines would give developers certainty that they would not face prosecution, and would generate a dialog between wind developers and the Fish and Wildlife Service to help minimize and mitigate bird impacts,” he added.

“Given the Administration’s commitment to scientific integrity, it’s hard to understand why the peer-reviewed work of agency scientists was dismissed in favor of text written by an industry-dominated Federal Advisory Committee,” said Kelly Fuller, Wind Campaign Coordinator at ABC. “ABC would like to see the next draft include more of what the agency scientists wrote.”

Recommendations on wind energy were developed over a two-year period by an industry-dominated, 22-member Federal Advisory Committee and forwarded to the Secretary of the Interior in March 2010. Over the next year, U.S. Fish and Wildlife Service biologists made a series of changes to those recommendations to improve protection for birds. Those revised guidelines were then published for public comment in February 2011 (an overwhelming number of the comments called for the guidelines to be strengthened, not weakened). They also underwent scientific peer review. Last week, FWS re-issued a new draft of those guidelines, available at http://www.fws.gov/windenergy/docs/WEG_July_12_%202011.pdf that removed many of the key bird protection elements following pressure from industry.

“ABC supports bird-smart wind energy development in which birds can co-exist with wind energy. America must avoid repeating the mistakes we made with hydropower half a century ago, when we built dams without careful environmental review or consideration, necessitating spending millions of dollars today to remove them. We must likewise steer clear of the mistakes we are making today with coal, which result in costly impacts to public health and wildlife. These new guidelines are not bird-smart,” she added.

Parr said “The new guidelines would harm birds by only giving U.S. Fish and Wildlife Service (FWS) biologists responsibility to review wind projects within new, truncated deadlines, and without the funding to hire the requisite additional staff. The new draft guidelines would also protect fewer migratory birds than the earlier version and move away from DOI’s legal responsibility to protect all migratory bird species, not just ‘species of concern’.”

In addition, the new guidelines remove protections for both birds and people that FWS biologists had recommended in their peer-reviewed guidelines, including:

Allowing greater latitude in installing overhead power lines between wind turbines, which increases the risk to larger birds such as eagles, hawks, and cranes, instead of burying the lines.

Removing a recommendation that wind developers address wildfire risk and response planning, something that could be potentially very important, especially in Western communities or areas experiencing drought.

Removing a recommendation that wind developers avoid discharging sediment from roads into streams and waters, a standard recommendation at construction sites that protects water quality.

Removing a recommendation to avoid active wind turbine construction during key periods in the life histories of fish and wildlife, such as the nesting season for migratory birds.

The publication date for the final version of the guidelines has not yet been announced.
Concerned citizens have until August 4 to comment on the current guidelines. Comments can be sent to windenergy@fws.gov.

OUR SLEEPLESS NIGHTS WITH THE WIND TURBINES

By Andy Keeble

“When they were first put up we had a long spell of really nice weather and they weren’t working at all. But since we’ve had the wind and the recent spell of bad weather the noise is unbearable of a night time.”

“It’s unbelievable the noise they make sometimes,” said Mr Paulton, 68.

A Torrington couple are selling their home and business following the erection of a wind farm in a field opposite their bungalow.

Patricia and Arthur Poulton say they are being kept awake at night by the noise from a trio of giant turbines less than 500 metres from their home at Higher Darracott.

The couple, who have operated their Deepmoor Metal Processors scrap metal business from the site for the last 21 years, said they now had no option but to sell up and move on.

“I can hear the turbines through my pillow at night,” said Mrs Paulton, 70.

“It’s a droning whooshing sound and as the blade passes the upright, the windier it gets, the noisier it gets. I have to close the window but you can still just about hear it through the double glazing.

“When they were first put up we had a long spell of really nice weather and they weren’t working at all. But since we’ve had the wind and the recent spell of bad weather the noise is unbearable of a night time.”

“It’s unbelievable the noise they make sometimes,” said Mr Paulton, 68.

“They are supposed to be no more than five decibels above background noise but when the wind blows across the bungalow it’s surprising how far it travels.”

The 240ft turbines were constructed by FIM Services Ltd in March and became operational in April. Planning consent was originally refused by Torridge District Council in May 2004 but later granted by a Government Inspector following a High Court appeal by land owners.

When the Gazette visited the couple on Wednesday, heavy blobs of white and grey cloud blotted out all but a few snatches of blue sky. On the hillside overlooking Torrington, two of the three turbines turned in a stiff breeze.

On the approaches to the town, the first of 22 ESB Wind Development UK turbines can be seen being built at Fullabrook Down on the other side of the Taw Estuary.

When the sun does shine here – especially towards the end of the day – the couple say the blades produce a “flicker shadow” over their bungalow.

“The sun goes down right behind the turbines and you get this strobe effect,” said Mrs Paulton, who suffers from Ménière’s disease – a disorder of the inner ear that can affect hearing and balance.

“They also produce a low frequency noise that you can’t hear but can cause dizziness, nausea and headaches. I’m not sure if it’s a coincidence but I’d not been ill for about five months but as soon as the turbines started I was sick for two weeks and have had to take the medication.

“We had a couple of break-ins at the yard last year and were thinking of selling up, but this has been the final straw.”

The couple have been in contact with Torridge District Council and have been asked to fill in forms to record their disturbance.

A spokesperson for the council said an official investigation had already started.

A statement from the council said: “The necessary forms have been sent to the complainants and our environmental protection team is awaiting the return of the paperwork with a diary of noise disturbances to see whether or not further investigation is required.”

Regarding shadow flicker, it said: “In the planning permission the inspector stipulated that a report should be submitted on shadow flicker which concluded that there would be very little chance of it happening. However, should it occur, effective steps should be taken to stop it.”

The couple were keen to point out that they were not concerned about the turbines’ impact on the landscape.

“We’re not bothered about how they look,” said Mrs Paulton.

The Gazette contacted FIM Service but a spokesperson was unavailable for comment.

Overcoming President Obama's Wind Power Addiction

An alternative form of energy with embarrassingly underwhelming returns.

Cumulative federal subsidies for wind are now well north of $100 billion. The very business running the Pennsylvania facility at which Obama made that bold prediction--Spanish wind company Iberdola--has received an astounding $1 billion in grants, tax credits and other incentives from the U.S. government (a.k.a., you and me).

This spring, Secretary of the Interior Ken Salazar announced federal approval for the construction of a huge new offshore wind farm in Massachusetts. The so-called Cape Wind project will include 130 turbines, each roughly 440 feet tall, and span 25 miles of ocean off the coast of Cape Cod. Construction is expected to commence this fall--assuming the troubling economics of the project can be resolved.

Getting Cape Wind approved was no easy task. The project had been stalled in controversy for nearly a decade. Even the late Sen. Ted Kennedy opposed the turbines for spoiling the tranquility of his seaside vacation home.

But Cape Wind survived its environmental review. And that's in no small part due to the Obama administration. Expanding wind power is core to the president's peculiar, ill-defined green energy agenda. At an April visit to a Pennsylvania turbine manufacturing facility, he went so far as to declare wind "the future of American energy."

That's quite a claim--and hardly true. Our country's history with wind power consists of grand promises from politicians, huge investments of taxpayer dollars, ratepayer sacrifice and embarrassingly underwhelming returns. More of the same can be expected.

Of the $10 billion invested by wind developers last year, $3.4 billion came in the form of federal grants. Thus taxpayers picked up a full one-third of the tab. And ratepayers have no choice but to pay the extra cost from wind power in states that mandate its use even after the tax subsidies.

Cumulative federal subsidies for wind are now well north of $100 billion. The very business running the Pennsylvania facility at which Obama made that bold prediction--Spanish wind company Iberdola--has received an astounding $1 billion in grants, tax credits and other incentives from the U.S. government (a.k.a., you and me).

WIND POWER TURBINES AT ALTAMONT PASS THREATEN PROTECTED BIRDS

Read entire story at the source: Los Angeles Times, www.latimes.com

June 6, 2011

By Louis Sahagun

“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.”

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.”

The fate of the Bay Area’s golden eagles highlights the complex issues facing wildlife authorities, wind turbine companies and regulatory agencies as they promote renewable energy development in the Altamont Pass and across the nation and adds urgency to efforts to make the technology safer for wildlife, including bats, thousands of which are killed each year by wind turbines.

Gov. Jerry Brown in April signed into law a mandate that a third of the electricity used in California come from renewable sources, including wind and solar, by 2020. The new law is the most aggressive of any state.

The development and delivery of renewable energy is also one of the highest priorities of the Interior Department, which recently proposed voluntary guidelines for the sighting and operation of wind farms. Environmental organizations led by the American Bird Conservancy had called for mandatory standards.

The U.S. Fish and Wildlife Service authorizes limited incidental mortality and disturbance of eagles at wind facilities, provided the operators take measures to mitigate the losses by replacing older turbines with newer models that are meant to be less hazardous to birds, removing turbines located in the paths of hunting raptors and turning off certain turbines during periods of heavy bird migration. So far, no wind energy company has been prosecuted by federal wildlife authorities in connection with the death of birds protected by the Migratory Bird Act, the Bald and Golden Eagle Protection Act or the federal Endangered Species Act.

The survival of the Bay Area’s golden eagles may depend on data gathered by trapping and banding and then monitoring their behavior in the wilds and in wind farms.

On a recent weekday, Bell shinnied up the gnarled branches of an old oak to a bathtub-sized golden eagle nest overlooking a canyon about 25 miles south of Altamont Pass.

Two fluffy white and black chicks, blinked and hissed nervously as he scooped them up and placed them into cloth sacks. He attached the sacks to a rope and delicately lowered them 45 feet to the ground.

“As adults, these birds could eventually wind up anywhere in the Western United States or Mexico — that is, if they live that long,” Bell said.

With field biologist Joe DiDonato, he banded the birds’ legs and recorded their vital statistics in a journal that chronicles more than a decade of raptor research in the region. The message is a grim one.

Each year, about 2,000 raptors are killed in the Altamont Pass by wind turbines, according to on-site surveys conducted by field biologists. The toll, however, could be higher because bird carcasses are quickly removed by scavengers.

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.

And while “there’s quite a bit of growth to come in wind energy development, it won’t be popping up everywhere,” said attorney Allan Marks, who specializes in the development of renewable energy projects. “That is because you can only build these machines where the wind is blowing. So a lot of the new development will be replacing old facilities in areas such as Cabazon, the Tehachapi Mountains and Altamont Pass.”

Nonetheless, the generating facilities will continue to threaten federally protected species such as eagles and California condors, a successfully recovered species that is expanding its range into existing and proposed wind farms in Kern and Fresno counties.

NextEra Energy’s proposed North Sky River Project calls for 102 wind turbines across 12,582 acres on the east flank of the Piute Mountains, about 17 miles northeast of the Tehachapis. A risk assessment of that project warned that condors spend considerable time soaring within the potential rotor-swept heights of modern wind turbines, which are more than 200 feet tall. It also pointed out that condor roosts are as close as 25 miles away.

“We taxpayers have spent millions of dollars saving the California condor from extinction,” said Gary George, spokesman for Audubon California. “How’s the public going to feel about wind energy if a condor hits the turbines?”

In the meantime, raptors such as golden eagles, American kestrels, red-tail hawks and prairie falcons continue to compete with wind turbines for their share of the winds blowing from the southwest through the Altamont Pass.

Golden eagles weigh about 14 pounds, stand up to 40 inches tall and are equipped with large hooked bills and ice-pick talons. Their flight behavior and size make it difficult for them to maneuver through forests of wind turbine towers, especially when distracted by the sight of prey animals such as ground squirrels and rabbits.

“The eagles usually die of blunt-force trauma injuries,” Bell said. “Once, I discovered a wounded golden eagle hobbling through tall grass, about a quarter mile from the turbine blades that had clipped its flight feathers.”

As he spoke, an adult male golden eagle glided a few yards above the contours of Buena Vista’s sloped grasslands, prowling for prey. It floated up and over a rise, narrowly evading turbine blades as it followed the tantalizing sight of a ground squirrel scurrying through the brush.

Bell sighed with relief. “A wind farm owner once told me that if there were no witnesses, it would be impossible to prove a bird had been killed by a wind turbine blade,” he said. “My response was this: If you see a golden eagle sliced in half in a wind farm, what other explanation is there?”
