Cost, space, safety risk, threats to flora and fauna, noise, aesthetic intrusion, shadow flicker: problems with wind energy

Ton van de Wekken, of KEMA Nederland, an energy systems consultancy, writes in the April 1 Renewable Energy World (excerpts):

The costs of onshore wind ranges from €55–100/MWh, depending on the wind resource. For most locations, though, wind energy is not cost-effective and incentives are a prerequisite to make a wind farm profitable.

Inevitably, offshore wind farms are more expensive to develop than onshore farms – requiring about double the initial investment and double the operational costs – due to the extra costs of construction, transport to site and interconnection.

Initiation and feasibility

... Wind farms require large sites. Depending on the rotor diameter the required mutual separation is 300–500 metres with a similar separation distance from dwellings and commercial buildings to limit noise nuisance and provide a safety zone. Even for a medium-sized wind farm, say 5 × 2 MW machines, a substantial land area is required.

Planning requirements of local authorities

The wind farm site has to meet planning and regulatory requirements. In most countries wind turbines may not rotate above roads, railway tracks and waterways, and a minimum clearance from public infrastructure must be observed such as facilities for transport, storage or processing of hazardous goods, and residential, commercial or public buildings.

In northern countries and countries with a continental climate, specific attention has to be paid to the possibility of icing. Ice developed on rotating rotor blades can be thrown long distances, potentially causing injury and damage and planning authorities and regulatory bodies may require an additional risk analysis if the site is subject to icing.

There may also be a zoning plan that prohibits wind turbines or limits the maximum height of structures. Under such circumstances, the relevant authorities should be approached to investigate the possibility of obtaining permission at the earliest possible stage.

In most European countries wind turbines must also be certified according to the relevant national or international safety standards. Manufacturers have to demonstrate conformance by the production of a valid type-certificate.

For any proposed wind farm the following should be considered:
  • Check municipal zoning plan on competing activities and maximum building height
  • Mutual distance between wind turbines 400 metres
  • There are to be no buildings and as few obstacles as possible within 300–500 metres
  • Authorities or concerned parties may request a risk analysis if other activities are to take place within 400–500 metres of the wind turbines.
Planning procedures and environmental issues

The wind farm must comply with all relevant environmental regulations. This may require a number of studies of, for example, the effects on birds, animals and plant life during the construction and use phases. Key parameters include noise, visual impact and safety, and most planning authorities also demand safety and risk assessment studies.

Wind turbines produce noise, mostly caused by the rotor blades and drive train, and the noise impact of wind turbines on the environment is one of the major planning issues. The distance to nearby residential buildings has to be sufficient to ensure that the noise level at the house front is below the statutory limit. The visual impact of a wind farm is also an important planning consideration. Wind farms require open, often elevated, sites and are consequently highly visible from a distance. Many of the potentially most productive sites are in areas of great natural beauty where planning regulation can be very restrictive. Shadow flickering on dwellings and offices due to the periodic – about once per second – passage of the rotating blades across the sun can be very annoying for the occupants, although it is not regulated by law.

Paul Gaynor forgets to mention mafia connection

In today’s New York Times, First Wind CEO Paul Gaynor writes:

In 2004, another G.E. colleague asked me to join UPC Wind Management as president and chief executive, and I accepted. Because another wind company had a similar name, we changed our name to First Wind in 2008.
That “other” wind company was in fact its own parent. They changed the name because its deep corruption was coming to light in Italy. That “other GE colleague” was Brian Caffyn  ...

UPC Solar: Our Management
Mr. Caffyn ... was the founder and inaugural Chairman of UPC Wind (now First Wind). ... Mr. Caffyn is also Managing Partner of UPC Capital Partners and UPC Energy Partners. He spent the first part of his career in project financing for wind, cogeneration, hydro, solar, geothermal, waste-to-energy and biomass energy projects with GE Capital, Heller Financial, Inc., and several private companies. Mr. Caffyn personally oversaw the establishment and construction of the largest wind energy company in Italy — Italian Vento Power Corporation.
Brian Caffyn: Executive Profile & Biography, Business Week
Mr. Caffyn is a co-founder of UPC Energy Group and UPC Group. ... He founded First Wind Energy Company in 1996 ... He founded First Wind Holdings, Inc. and served as its Chairman. He founded and served as Chairman of First Wind Energy LLC (UPC Wind Partners, LLC). ... Mr. Caffyn served as Director or Partner of ... Italian Vento Power Corporation (IVPC), Srl, ...
Caffyn, founder and former CEO and [still?] chairman, has been expunged from mention on the First Wind web site.

Italian Vento Power Corporation: Background
The Group [Italian Vento Power Corporation] came to light in 1993 from an idea of Oreste Vigorito who formed the company IVPC Srl on behalf of UPC, an American company which operates in the wind sector in California. ...

Between 1996 and 2000, UPC forms several project companies for the installation of new Wind Farms in the Campania Region, in Sardinia and in Sicily. During this period, the Group develops 241MW. In 2005, UPC sells its assets held in Italy to the Irish group Trinergy and furthermore, sells the 50% of the original IVPC Srl (with its trade mark) to Oreste Vigorito who remains in partnership with Eurus Energy (ex Tomen) which owns the other 50%.

Trinergy, in its turn, in 2007, sells the assets previously acquired from UPC to the English group International Power [IP]. Oreste Vigorito is Managing Director of the ex IVPC Group, previously called Trinergy and now IP Maestrale, until November 2008 when he hands in his resignation.
Anti-mafia police make largest asset seizure, by Guy Dinmore, Financial Times, September 14, 2010
Italian anti-mafia police have made their largest seizure of assets as part of an investigation into windfarm contracts in Sicily. Officers confiscated property and accounts valued at €1.5bn belonging to a businessman suspected of having links with the mafia.

Roberto Maroni, interior minister, on Tuesday accused the businessman – identified by police as Vito Nicastri and known as the island’s “lord of the winds” – of being close to a fugitive mafia boss, Matteo Messina Denaro.

General Antonio Mirone, of the anti-mafia police, said the seized assets included 43 companies – some with foreign participation and mostly in the solar and windpower sector – as well as about 100 plots of land, villas and warehouses, luxury cars and a catamaran. More than 60 bank accounts were frozen. ...

The renewable energy sector is under scrutiny across much of southern Italy. Some windfarms, built with official subsidies, have never functioned. ...

Mr Nicastri sold most of his windfarm projects to IVPC, a company near Naples run by Oreste Vigorito, also president of Italy’s windpower association. Mr Vigorito was also arrested last November on suspicion of fraud and later released.
Green energy tangled in web of shady deals, by Guy Dinmore, Financial Times, May 5, 2009
Over coffee, Mr Nicastri confirms that he has developed the "majority" of Sicily's wind farms, arranging land, financing and official permits. He then sold the projects for construction to IVPC, a company run by Oreste Vigorito, who is also president of Italy's wind power association.

Mr Nicastri says he has worked on projects resulting in construction of wind farms for International Power (IP) of the UK; Falck Renewables, the London subsidiary of Falck Group based in Milan; IVPC; and Veronagest, another Italian company.

"I am not a prostitute for everyone. There are other prostitutes for the others," Mr Nicastri laughs, mentioning other multinationals with wind assets in Sicily. ...

IP became the single largest wind farmer in Italy with its 2007 purchase of the Maestrale portfolio of mostly Italian wind farms, including five in Sicily, for €1.8bn from Trinergy, an Irish company, which had purchased them from IVPC.
Wind Power, by Joan Killough-Miller, WPI [Worcester Polytechnic Institute] Transformations, Summer 2005
As president and CEO of UPC Wind Management, located in Newton, Mass., Gaynor was tapped to bring the success of the parent company, UPC Group, to North America. In Europe and North Africa, UPC affiliates — including Italian Vento Power Corporation — have raised over $900 million in financing and installed some 900 utility-scale wind turbine generators (WTGs), with a total capacity of more than 635 megawatts. UPC subsidiary companies, positioned across the United States and in Toronto, are currently pursing some 2,000 megawatts in projects from Maine to Maui.
Also of note from Gaynor's NY Times piece: “Some people will always be against development, whether it’s a shopping mall, a condo project or a wind farm.” Yes, “wind farms” are “development”, no different from shopping malls and condo projects, which is why they should similarly never be allowed on the ridges, open spaces, and coasts that wind developers target.

Kittitas Valley Audubon Society rejects wind

The Kittitas Audubon Society board of directors on September 2 voted 10-3 to oppose three wind facilities proposed in the Kittitas valley of central Washington state.

"Kittitas Audubon believes that lacking a national, state, and local commitment within the framework of a national energy policy to promote conservation, the [perception of -- KM] additional energy supplied by the wind farms will only help continue and actually increase the current wasteful level of energy use. National, state, county, and city governments must develop energy conservation strategies to offset the demand for more energy. Wind farm development in this county is at a stage similar to that of hydropower 50 years ago and of nuclear power 25 or more years ago. Planners for those projects likely thought they had planned things well. However, here we are in 2004 with drastically impacted fish stocks, searching for ways to restore them that include removal of dams. We are still trying to find places to store nuclear waste, and attempting to clean up the leaking sites at Hanford before contamination reaches the Columbia River. Now we have an overnight overwhelming rush to build numerous industrial wind farms in this part of the Kittitas valley that occupy thousands of acres -- 7,000 acres for the KVWPP [one of the projects] alone. Since we cannot predict with reasonable accuracy the long-term environmental impacts of these projects, it is imperative that caution be taken. Policies and guidelines must be in place to protect the natural environment with special consideration for birds and bats. Wind power developers are guests of Kittitas County. Citizens of the county are the ones whose lands and environment will be affected by the wind farms. Kittitas Audubon Society is a voice for the birds of this valley and those that pass through. Our comments and recommendations are made from a perspective that the air space must be kept safe for birds and bats.

"KAS Board of Directors voted not to approve applications for any of the three wind farms because of the lack of adequate study of environmental factors affecting birds, bats, and habitat. Also, the cumulative effects of the three wind farms in relationship to other existing and future wind farms have not been studies or considered. Conservation of energy should be promoted as an alternative."

((((((((((

Here's an appropriate quote from another story. "They creep closer and closer to the marsh with larger and larger turbines," said Nick Jacobs [of Advocates for the Suisun Marsh (near San Francisco, California, and the largest contiguous brackish water marsh remaining on the west coast of North America)].

((((((((((

And to help you think about the size of industrial windmills, the 35-meter blades of a 1.5-MW GE assembly sweeps an acre of air, at a speed of up to 165 mph at the tips.

Stretching and ignoring the facts about wind power

Glenn Schleede has written a new paper about industrial wind energy, mostly looking at the economics: "Stretching or Ignoring Facts and Making Unwarranted Assumptions When Attempting to Justify Wind Energy." It can be downloaded from the National Wind Watch Resource Library. Here is the outline of section D, which concisely lists the issues to be weighed.

D. Facts about wind energy that are often ignored by federal, state and local officials when considering wind energy policies or facilities
 1. Electricity produced by wind turbines is lower in quality and value than electricity produced from reliable generating units.
 2. Building wind turbines will not replace the need for building reliable, dispatchable generating capacity.
 3. Published information on the cost of electricity from wind per kWh generally is not valid or reliable.
 4. True costs of electricity from wind are much higher than often admitted because important elements of cost are ignored.
  a. Federal and state tax breaks for wind energy are part of the true cost of electricity from wind.
   1) Two very generous tax breaks are available from the federal government.
    • The wind production tax credit (PTC) of $0.019 per kWh for electricity produced during the first ten years of a wind facility's operation.
    • The ability to deduct the entire capital cost of a "wind farm" from taxable using 5-year double declining balance accelerated depreciation.
   2) "Wind farms" enjoy other tax breaks from the state.
   3) Other subsidies are also a part of the true cost but are hidden in either tax or monthly electric bills.
  b. The intermittent, volatile and unreliability of electricity from wind turbines also adds to the true cost of that electricity.
  c. Adding transmission capacity to serve "wind farms" adds to customer costs.
 5. Local economic benefits of "wind farms" are generally exaggerated.
 6. Environmental benefits of wind energy are typically overstated.
 7. Wind energy advocates try to ignore adverse environmental, ecological, scenic and property value impacts of "wind farms."

"An ugly face of ecology"

George Monbiot has written an incisive critique of industrial wind power and its "green" supporters. It is in the Guardian (click the title of this post) as well as on his own site, where it includes notes.
The people fighting the new wind farm in Cumbria have cheated and exaggerated. They appear to possess little understanding of the dangers of global warming. They are supported by an unsavoury coalition of nuclear-power lobbyists and climate-change deniers. But it would still be wrong to dismiss them. ...

Wind farms, while necessary, are a classic example of what environmentalists call an "end-of-the-pipe solution". Instead of tackling the problem - our massive demand for energy - at source, they provide less damaging means of accommodating it. Or part of it. The Whinash project, by replacing energy generation from power stations burning fossil fuel, will reduce carbon dioxide emission by 178,000 tonnes a year. This is impressive, until you discover that a single jumbo jet, flying from London to Miami and back every day, releases the climate-change equivalent of 520,000 tonnes of carbon dioxide a year. One daily connection between Britain and Florida costs three giant wind farms.

Alternative technology permits us to imagine that we can build our way out of trouble. By responding to one form of overdevelopment with another, we can, we believe, continue to expand our total energy demands without destroying the planetary systems required to sustain human life. This might, for a while, be true. But it would soon require the use of the entire land surface of the UK. ...

I believe the Whinash wind farm should be built. But I also believe that those who defend it should be a good deal more sensitive towards local objectors. Why? Because in any other circumstances they would find themselves fighting on the same side.
Monbiot is right to express discomfort with the pro-nuclear and climate-change-denying tendencies of many wind energy opponents. Yet ultimately they are defending the landscape against needless industrialization. Many opponents are indeed conservationists and defenders of wildlife without the baggage Monbiot decries. Even Greenpeace, adamantly pro-wind, has balked at the extent of the proposed facilities on the island of Lewis, as has almost every wildlife and natural heritage group. Many opponents recognize the problem exactly as Monbiot describes it and agree with his assessment of the futility of building ever more giant wind farms. How he concludes from this forthright analysis that industrial wind facilities are "necessary" is a mystery.

Monbiot argues from the need to reduce carbon emissions, pointing out that wind turbines currently provide only 0.32% of the U.K.'s electricity. That represents the output from 888.8 MW of wind power, according to the British Wind Energy Association. The addition of the 67.5-MW Whinash Wind Farm would increase that to 0.34%. To get to the target of 10% would require the addition of 26,576 MW after Whinash (using the less-rounded figures from Monbiot's notes). No wonder capital is so excited. No wonder sensible people resist.

"This sentence is dangerous"

The Den Brook Judicial Review Group were recently successful in a Freedom of Information request to obtain drafts of a government-contracted report about noise levels from wind turbine facilities: "The measurement of low frequency noise at three UK wind farms" by Hayes McKenzie Partnership Ltd. for the (former) Department of Trade and Industry, 2006, contract no. W/45/00656/00/00; URN no. 06/1412. See the material posted at National Wind Watch, by courtesy of the Den Brook Judicial Review Group.

3rd draft, page 35:
It is important to note, however, that for Site 1: Location 1, the occupant complained of wind turbine noise only after being woken by the passage of a motor vehicle on the nearby A-Class road. As such, this indicates that, rather than wind turbine noise resulting in noise which is of sufficient level as to awaken a sleeping person, it is the inability to return to sleep associated with some audible wind turbine noise within the bedroom which is of more concern to that occupant. A difficulty in returning to sleep will result in tiredness the next day and all the associated descriptions of ill health which might be associated with a lack of sleep – this sentence is dangerous and could be read that windfarms cause ill-health which is not the intention. We need the report to stick to the facts that LFN is bleow the guidelines but that once woken by a car there may be problems getting gback to sleep for those with sensitive hearing as result of the windfarm – something like that.[Personal Details/Name of official removed under Reg 12(3) of the EIRs]
In the final report, page 48, the "dangerous" sentence has been deleted.

It is also interesting to note how the conclusion statements regarding aerodynamic modulation changed from draft to final report:

3rd draft, pages 45-46 (essentially the same from 2nd draft, not yet written in 1st draft):
The common cause of complaints associated with wind turbine noise at all three wind farms is the audible modulation of the aerodynamic noise, especially at night. Although the internal noise levels associated with this noise source are not high enough to result in the awakening of a resident, once awoken the audibility of this noise results in difficulties in returning to sleep.

The analysis of the external and internal noise levels indicates that it may be appropriate to re-visit the issue of the absolute night-time noise criterion specified within ETSU-R-97. To provide protection to wind farm neighbours, it would seem appropriate to reduce the absolute noise criterion for periods when background noise levels are low. In the absence of high levels of modulation, then a level of 38 dB LA90 (40 dB LAeq) will reduce levels to an internal noise level which lies around or below 30 dB LAeq with windows open for ventilation. In the presence of high levels of aerodynamic modulation of the incident noise, then a correction for the presence of the noise should be considered.
Final report, page 67 (deletions indicated, and additions in italics):
The common cause of complaints associated with wind turbine noise at all three wind farms is not associated with low frequency noise, but is the audible modulation of the aerodynamic noise, especially at night. Although the internal noise levels associated with this noise source are not high enough to result in the awakening of a resident, once awoken the audibility of this noise can results in difficulties in returning to sleep. It is also not uncommon for a wind farm to be identified as a cause of the awakening although noise levels and the measurements/recordings indicate to the contrary.

The analysis of the external and internal noise levels indicates that it may be appropriate to re-visit the issue of the absolute night-time noise criterion specified within ETSU-R-97. To provide protection to wind farm neighbours, it would seem appropriate to reduce the absolute noise criterion for periods when background noise levels are low<. In the absence of high levels of modulation, then a level of 38 dB LA90 (40 dB LAeq) will reduce levels to an internal noise level which lies around or below 30 dB LAeq with windows open for ventilation aerodynamic modulation and the means by which it should be assessed. In the presence of high levels of aerodynamic modulation of the incident noise, then a correction for the presence of the noise acoustic feature should be considered.

Reviews of wind turbines’ effects on human health

Elsewhere on this blog, there is an inclusive list of reviews of the literature concerning human health and the noise from industrial wind turbines. It was compiled to provide a more complete list than the highly selective one presented by Simon Chapman of the University of Sydney that is often cited by wind power promoters. It also showed that while Chapman presented the reviews as reason to dismiss health concerns, most of them actually note the limited number and power of studies but that the evidence justifies further investigation and caution.

Most of the reviews, however, are government reports: nine of Chapman’s original 17, all of the three he later added, and five of the additional reviews listed earlier on this blog. Furthermore, of Chapman’s list, four are irrelevant (three not about wind turbines and one a press release about one of the other reviews), two are industry reports, and two are just rehashes of an earlier review. Only three of the reviews he originally listed merit attention:

Vetting these eleven, we find that: Dani Fiumicelli is Technical Director (Head of Noise and Vibration) of Temple Group, a development consultancy in the U.K., and is an author of a 2013 report for the Scottish government to deny concerns of health effects; Loren Knopper is Senior Scientist and Christopher Ollson is Vice President for Strategic Development of Intrinsik, an environment and health consultancy in Ontario, and in their paper they disclose that they “have worked with wind power companies”, that Ollson “has acted as an expert witness for wind power companies during a number of legal hearings”, and that all of the authors of their 2014 review are also disclosed to be employees of Intrinsik: “the authors work for a consulting firm and have worked with wind power companies”; in 2015 the Canadian Wind Energy Association honored Knopper and Ollson with their R. J. Templin Award for “results that have served to significantly advance the wind energy industry in Canada”; Mark Roberts is Principal Scientist of Exponent, an engineering and scientific consulting firm involved in wind energy development; and Kurpas et al. mention in passing towards the end of their paper that they “are involved in community public consultations with the advocates of new projects”. These potential conflicts are noted in the following quotes (ordered by date).

Villey-Migraine: “Wind turbines emit infrasound, this is not disputed by anyone. ... It seems to us immoral on the part of this organization [Agency of the Environment and Energy Management] to assert, without any reference, that infrasound emitted by wind turbines is perfectly harmless, and furthermore, to make claims of so-called ‘action,’ but that we can not prove the impact of wind turbine infrasound on humans by epidemiological studies. ... Noise and infrasound emitted by wind turbines have a definite impact on the health of humans and can harm people’s lives. ... Wind developers have a responsibility to put in place adequate measures to reduce the risks of damage to the health of residents living near wind turbines by siting turbines no closer to homes than – not 500 m as suggested in their publications – but 1600 m considering audible noise and at least 5 km considering infrasound.” [translated]

Chouard: “Whether it is quite intense or it represents a more moderate noise pollution, noise is the complaint most frequently made concerning wind turbines. It can have a real impact, and so far disregarded, on human health. ... It would be desirable, as a precaution, to halt the construction of wind turbine facilities greater than 2.5 MW closer than 1500 meters from homes.” [translated]

NRC: “In the absence of extensive data, this report focuses mainly on appropriate methods for analysis and assessment and on recommended practices in the face of uncertainty. ... Low-frequency vibration and its effects on humans are not well understood. Sensitivity to such vibration resulting from wind-turbine noise is highly variable among humans. ... More needs to be understood regarding the effects of low-frequency noise on humans.”

Quambusch & Lauffer: “There is no doubt that wind turbines produce infrasound. In contrast to the pronouncements of the authorities, plant operators, and related institutions that infrasound is "completely harmless", there are an increasing number of scientists noting the health risks of infrasound. The risk is sufficient that new regulations are required for prevention. As long as and to the extent that the health risks are not prevented by technical or similar guidelines, construction and operation of these plants should be allowed only if they are out of sight of residential areas.” [translated]

Knopper &: Ollson [industry consultants, non-medical]: “wind turbines can be a source of annoyance for some people”

Fiumicelli [industry consultant, non-medical]: “uncertainty about human response to wind turbine noise”

James [acoustician, non-medical]: “There is sufficient research and history to link the sensitivity of some people to inaudible amplitude-modulated infra and low-frequency noise to the type of symptoms described by those living near industrial wind turbines.”

Hanning & Evans: “A large body of evidence now exists to suggest that wind turbines disturb sleep and impair health at distances and external noise levels that are permitted in most jurisdictions ... Sleep disturbance may be a particular problem in children, and it may have important implications for public health. ... Robust independent research into the health effects of existing wind farms is long overdue.”)

Farboud et al.: “There is some evidence of symptoms in patients exposed to wind turbine noise. The effects of infrasound require further investigation.”

Doolan: “Low-frequency noise levels from wind turbines may exceed audibility thresholds and thus it is possible that they are correlated with annoyance. A review of studies related to general low-frequency noise annoyance shows there are similarities with annoyance studies involving wind turbine noise. ... noise levels may comply with existing environmental noise guidelines based on the dB(A) scale yet still cause annoyance due to the uniqueness of low-frequency noise problems. However, there is very little information (level, spectral balance, temporal qualities, etc) regarding low-frequency noise in people’s homes affected by wind turbines. ... Thus more research is needed in understanding the fundamental aspects of wind turbine low-frequency noise generation, propagation and perception.”

Roberts & Roberts [industry consultants]: “The answer to the question of whether or not exposure to wind turbine sound is a human health risk is still under review and warrants further research. Although limited, research has demonstrated that LFS [low-frequency sound] can elicit adverse physical health effects, such as vibration or fatigue, as well as an annoyance or unpleasantness response. The current research on exposure to wind turbine sound and the mere presence of wind turbines have also demonstrated a significant annoyance response among study participants. But the association and particular pathway between LFS specifically generated from wind turbines, annoyance, and adverse physical health effects have yet to be fully characterized.” [These authors also ignore the Nissenbaum et al. study in Noise & Health.]

Kurpas et al. [industry consultants]: “Short description of state of the art: The nuisance caused by wind turbines is stereotypically linked with the noise that they produce. Nevertheless, the visual aspect of wind farms, opinions about them, and sensitivity to sound seem to be of the greater importance. ... Health effects are more probably associated with some environmental factors leading to annoyance or frustration. All types of studies share the same conclusion: wind turbines can provoke annoyance. ... The influence of wind turbines on human emotional and physical health is a relatively new field of research. Further analyses of these issues are justified, especially because none of the studies published in peer-reviewed journals so far meet the criteria for cohort or case-control studies. ... The authors did not analyse coherent publications or website documents (study by M. Alves-Pereira and N.C. Branco and the study by N. Pierpont).” [The authors also missed the Nissenbaum 2012 paper in Noise & Health, which appeared after their submission. And they assert that noise from wind turbines cause only subjective effects, despite the evidence under review of interference with, e.g., sleep, and physiological effects.]

Enbom & Malcus Enbom: “Infrasound from wind turbines affects the inner ear and is a potential health risk for people with migraine or other type of central sentitisation. Regulations for construction of wind turbines should be revised, taking this fact into account.” [translated]

Nissenbaum: “In summary, in many IWT projects, the preconstruction sound modeling has underestimated the eventual real world sound levels those turbine projects eventually produce. When coupled with the underappreciated human physiological responses to the type of noise large turbines produce (adverse sleep and mental health effects), this has had real world consequences for those living near them. The relationship of noise to sleep disturbances is established. The biological plausibility of sleep disturbances resulting in ill health is settled science. Chronic noise exposure leads to chronic sleep disturbance in many of those exposed, often resulting in ill health. Observed adverse human effects must trump preconstruction sound modeling; changes in practice must occur when there are errors. It’s all about distance when siting decisions are made.”

Arra et al.: “In this review, we have demonstrated the presence of reasonable evidence (Level Four and Five) that an association exists between wind turbines and distress in humans. The existence of a dose-response relationship (between distance from wind turbines and distress) and the consistency of association across studies found in the scientific literature argues for the credibility of this association.”

Knopper, Ollson, et al. [industry consultants, non-medical]: “Setbacks should be sound-based rather than distance-based alone. Preference should be given to sound emissions of ≤40 dB(A) for non-participating receptors, measured outside, at a dwelling, and not including ambient noise. ... Post construction monitoring should be common place to ensure modeled sound levels are within required noise limits. If sound emissions from wind projects is in the 40–45 dB(A) range for non-participating receptors, we suggest community consultation and community support. Setbacks that permit sound levels >45 dB(A) (wind turbine noise only; not including ambient noise) for non-participating receptors directly outside a dwelling are not supported due to possible direct effects from audibility and possible levels of annoyance above background. When ambient noise is taken into account, wind turbine noise can be >45 dB(A), but a combined wind turbine–ambient noise should not exceed >55 dB(A) for non-participating and participating receptors. Our suggested upper limit is based on WHO conclusions that noise above 55 dB(A) is ‘considered increasingly dangerous for public health,’ is when ‘adverse health effects occur frequently, a sizeable proportion of the population is highly annoyed and sleep-disturbed’ and ‘cardiovascular effects become the major public health concern, which are likely to be less dependent on the nature of the noise.’”

Schmidt and Klokker: “At present it seems reasonable to conclude that noise from wind turbines increases the risk of annoyance and disturbed sleep in exposed subjects in a dose-response relationship. There seems to be a tolerable limit of around LAeq of 35 dB. Logically, accepting higher limits in legislations may lead to increased numbers of annoyed subjects. It therefore seems reasonable to conclude that a cautious approach is needed when planning future wind farms. Furthermore, there is an indication that noise annoyance and sleep disturbance are related and that disturbed sleep potentially can lead to adverse health effects. These conclusions are, however, affected by a potential risk for selection and information bias even in the larger cross-sectional studies providing the current best evidence. The evidence for adverse health effects other than sleep disturbance is primarily supported by case-series reports which certainly may be affected by various sources of bias. Larger cross-sectional surveys have so far been unable to document a relationship between various symptoms such as tinnitus, hearing loss, vertigo, headache and exposure to wind turbine noise. One limitation causing this could be that most studies so far have only measured LAeq or Lden. An additional focus on the measurement of low-frequency sound exposure as well as a more thorough characterisation of the amplitude modulated sound and the relationship between objective and subjective health parameters could lead to different conclusions in the future. Finally, in regards to the objective measurement of health-related disorders in relation to wind turbine noise, it would be valuable to demonstrate if such health-related outcomes fluctuate depending on exposure to wind turbine noise.”

Tran Ba Huy: “[L]e caractère intermittent, aléatoire, imprévisible, envahissant du bruit généré par la rotation des pales, survenant lorsque le vent se lève, variant avec son intensité, interdisant toute habituation, peut indubitablement perturber l’état psychologique de ceux qui y sont exposés. Ce sont notamment les modulations d’amplitudes causées par le passage des pales devant le mât qui sont dénoncées comme particulièrement dérangeantes.” [The intermittent, random, unpredictable, invasive character of the noise generated by the rotation of the blades, arising when the wind rises and varying along with its intensity, preventing habituation, can undoubtedly disturb the psychological state of those who are exposed to it. These include amplitude modulation caused by the passage of the blades in front of the mast, which is noted as particularly disturbing.] “[L]e groupe de travail recommande: ... de revenir pour ce qui concerne leur bruit (et tout en laissant les éoliennes sous le régime des Installations Classées pour le Protection de l’Environnement) au décret du 31 août 2006 relatif à la lutte contre les bruits du voisinage (relevant du code de Santé publique et non de celui de l’Environnement), ramenant le seuil de déclenchement des mesures d’émergence à 30 dB A à l’extérieur des habitations et à 25 à l’intérieur.” [The working group recommends returning to the decree of 31 August 2006 concerning the fight against neighborhood noise, reducing the the threshold for emergency measures to [ambient levels] 30 dBA outside residences and 25 dBA inside [limiting wind turbine noise to +5 dBA in daytime (7am–10pm) and +3 dBA at night (10pm–7am)].]

Also:  “There is clear evidence of an annoyance or irritability caused by the acoustic signal from wind turbines that appears to be greater compared to other equivalent-level environmental noise such as airport or road traffic noise. In this regard, wind turbine noise is unique in having low-frequency signal components including infrasound (below 20 Hz). The sounds that are audible have a distinct amplitude modulation component, generally described as a “swish” or “thump”. This rhythmic characteristic makes the noise difficult to ignore or to adapt to, and its enhanced perception compared to un-modulated noise appears to contribute to its increased annoyance factor. Biological health issues can arise when the irritability and annoyance leads to sleep disturbance and stress.” —Robert Harrison: On the biological plausibility of Wind Turbine Syndrome.

Which Side Are You On?

Eric Rosenbloom, president of National Wind Watch, replies (larger roman type) to Robert Freehling, research director of Local Power, Oakland, California (smaller italic type) ...

Subject: RE: [Fwd: rfk jr + on wind energy]
Date: Mon, 22 Aug 2011 19:15:25 -0700
From: rfreeh

... Wind Watch, the principle source of anti-wind material in this thread, opposes all wind power and refuses to support any form of renewable power. See this quote from their FAQ webpage:

“What do you support?

National Wind Watch supports an open and honest debate about our energy use and the costs and benefits of all methods of generation, efficient use, and conservation. NWW supports continuing research and development of new energy sources. NWW supports the protection of rural communities and wild places threatened by fruitless industrial development. The mission of National Wind Watch is to provide the information needed for proper debate about industrial wind power, particularly that which isn't provided by government agencies or the industry and its supporters.” http://www.wind-watch.org/faq-aboutus.php

In other words the only things that Wind Watch supports are “debate” and “research and development”. They cannot name one source of renewable energy that they support, even on their own FAQ page when they ask themselves this question. On this same FAQ page, Wind Watch acknowledges climate change and the destructive character of our current energy use.

Wind Watch's mission is to provide information about industrial wind, not to endorse any other energy source, renewable or otherwise. It is true that many opponents of industrial wind are skeptical about other renewables as well. It is also true that most support decentralized solar and geothermal. But Wind Watch's mission is to serve all opponents of industrial wind, no matter their views on other forms of energy.

They are the archetype of the NIMBY organization, yet they deny that they are NIMBY’s because they don’t like the negative implication of that label. In reality, they are planet destroyers claiming the garb of being pro-environment. They twist the facts to their case, and make statements removed from the full context. For instance, they try to minimize the contribution of wind to getting rid of coal, based upon the argument that “wind power does not and cannot contribute significantly to our electricity needs.” (wind-watch.org (http://wind-watch.org/) faq page)

The negative implication of "Nimby" derives from hypocrisy in one's opposition. Wind Watch supports such "Nimby"s in their local battles, but not their suggestion that industrial wind development is more appropriate elsewhere. Wind Watch advocates for local opposition because it is more more meaningful to fight to protect your own back yard, and most opponents — because they have been compelled to learn about what will be affecting their back yards — recognize that industrial wind development is not appropriate anywhere else as well.

In other words, most opponents are indeed fighting locally — that's called civic engagement — but without the hypocrisy implied by the "Nimby" pejorative.

Similarly, it is ridiculous to call such people "planet destroyers" who are fighting, after learning and weighing the costs and benefits of industrial wind development, to protect their part of the planet from large-scale industrial development.

What they fail to mention is that they personally want to do everything in their power to insure that wind never contributes significantly to our electricity needs.

This would be a more valid criticism if we did not already have the experience of Europe to learn from. Large-scale wind, even to the extent that Denmark boasts of, has not appeared to reduce coal use. It is the nature of wind energy that ensures that it can never contribute significantly to our electricity needs.

They also do not mention that wind is by far the most successful and fastest growing source of renewable energy. And that wind is on track to become one of the world’s major sources of energy within the next two decades. And that is why it is so important for opponents of renewable energy to take down wind above all.

This year worldwide installed wind power grew past 200 Gigawatts, with about 40 Gigawatts of new wind going in every year. By 2015 the rate of installation is forecast to increase to over 80 Gigawatts per year, with cumulative capacity reaching 500 Gigawatts. Total installed wind capacity should reach one Terawatt (trillion watts) sometime in the early to mid 2020s.

News on global wind capacity: http://www.renewableenergyworld.com/rea/news/article/2011/08/world-wind-market-record-installations-but-growth-rates-still-falling

Success in building wind turbines is not success in replacing other sources of energy. In fact, there was virtually no new coal capacity built in the U.S. for 20 years, until wind energy started to be developed in a big way. Similarly, natural gas keeps pace with wind, because it is necessary to add for dealing with wind's variability.

For scale: one Terawatt is the capacity of all the generation in the US combined, and the total world electric generation capacity is today about 4.5 Terawatts.

One Terawatt of wind will generate more electricity than all the coal plants in the US combined. Wind infrastructure has the fastest payback for embodied energy and carbon used in its construction of any energy source currently being used; and when generating electricity it consumes no fuel and emits zero carbon or other greenhouse gases. Thus, to say that hundreds of Gigawatts or a Terawatt of wind cannot contribute significantly to our electricity needs, and cannot reduce pollution and help protect the climate, is beyond absurd.

If there is already 200 GW of wind capacity installed, surely its contribution to meeting electricity demand, reducing pollution, and protecting the climate should be detectable.

I became involved with this issue in 2003 when I sought out information about what a small wind facility bordering where I lived at the time would entail. While I was concerned about the impact of such constructions on a wild ridgeline, I had no reason to be skeptical about the benefits. But I started to notice that the promises of wind were always in the future or expressed in theoretical equivalencies. There were no actual data showing benefits that justify the industrialization of any rural or wild place. There still aren't.

As comments about wind only being commercially viable due to “subsidies from taxpayers” in the form of tax credits, this is at best a half truth. The wind tax credit is about 2 cents per kilowatt-hour and it is only paid for the first ten years of a wind plant’s operation. Since wind turbines have an economic life of 20 years, this tax credit is only about 1 cent per kilowatt-hour when averaged over the life of the plant. This credit is paid for every kilowatt-hour generated, and thus is performance and value based.

Very few wind turbines last 20 years. Ten years is in fact a more realistic span for their useful life. Many don't make it that long. Besides the production tax credit, wind developers enjoy 5-year double-declining depreciation and in many places a forced market, not only of actual energy generated but also of "green tags", or renewable energy credits, a lucrative secondary market invented by Enron.

Again, however, generation of energy by a wind turbine does not necessarily translate to comparable reduction of fossil fuel use or carbon or other emissions.

This compares with solar power, which gets a 30% tax credit upfront. An investment credit established as a percentage of the initial cost of the solar plant means that the more the solar plant costs the higher the value of the tax credit. It also means that the solar plant gets the credit irrespective of how much electricity it generates. Thus, the wind power—unlike solar— has to actually earn its tax credits.

As part of the recent economic stimulus package, wind developers also have had the option of taking a 30% tax credit up front, or a 30% cash grant, instead of the 2.2-cents/kWh production tax credit.

In general, wind power tax credits are not “paid for” by taxpayers, they are simply taxes not collected by the federal government. In the case of wind, the infrastructure would mostly otherwise not get built; thus there is little or no real “revenue loss”. However, there are US congressional rules that require the credits to be offset by other adjustments to the budget.

On the other side of the balance, there will be significant tax revenues gained by the commercial activity of manufacturing, constructing and operating a wind plant. The California Energy Commission’s most recent in-depth report on cost of electricity generation shows that wind plants would pay, over the full life of the plant, about 8/10ths of a cent per kilowatt-hour in “ad valorum” expenses; i.e., property taxes. The report also shows that a wind plant will pay four times the amount of property tax per kilowatt-hour than a natural gas combined cycle baseload plant.

CEC Cost of Generation report (Table 6 on pdf p. 46 = document p. 28): http://www.energy.ca.gov/2009publications/CEC-200-2009-017/CEC-200-2009-017-SF.PDF

If wind worked, this would be a valid — and unnecessary — argument. Since wind does not show measurable benefits to the environment, and in fact shows significant adverse impacts to the environment, proponents are reduced to presenting it as a (very inefficient) works program.

The message to rural towns throughout the country, like that from any predatory capitalist in a third-world country, boils down to: "Give us your mountain/fields and we'll give you a shiny new firetruck."

The new local tax revenue from a wind plant offsets the federal tax revenue lost due to the Production Tax Credit. Thus, the federal government’s Wind Production Tax Credit helps local government raise more taxes by stimulating local economic activity in renewable energy. Other tax revenues will be created by employment and business activity of the wind plant, both direct and indirect. The result is that there is little to no net cost to taxpayers.

Again, that's no doubt what Exxon and GE and Florida Power & Light say to rationalize their nonpayment of income tax. And this critique does not consider the simple passing on to ratepayers the costs to utilities of integrating wind.

As for the ultimate NIMBY group Wind Watch’s claim that wind power is not “competitive” without tax credits, the RETI data base shows wind projects with cost of energy averaging about 13 cents per kilowatt-hour—with all tax benefits stripped away, and the CEC Cost of Generation report shows new natural gas combined cycle plants generating electricity at a levelized cost of about 12.5 cents per kilowatt-hour. If tax benefits are factored in, then the cost is lower. Both natural gas and wind power vary in cost over a wide range, and thus wind projects can generate electricity at a similar cost of energy as a new natural gas plant, when both plants are compared over their full lifecycle. It is noteworthy that the CEC’s cost estimate for natural gas power does not include any cost for carbon, and thus does not capture the externalized burden of climate change.

RETI database of potential renewable energy powerplants and cost of energy from them: http://www.energy.ca.gov/reti/documents/phase2B/CREZ_name_and_number.xls

Externalized costs are indeed important to consider. Wind has them, too, including a complete dependence on petroleum products, steel, concrete, and rare earth metals. But again, these are accounting games. Wind does not appear to measurably reduce the impacts of other sources; it just adds its own.

The email thread also points to an article and video from KATU.com in Portland citing a staffer from Bonneville Power Administration that wind does not provide any carbon benefit. Taken out of context that might seem an embarrassment for wind. However, Bonneville is quite different from most electric power providers in the US in its carbon profile, since its primary source of energy is from hydropower which has no carbon emissions. If you actually read the article it paraphrases a secondary source— Todd Wynn— from the Cascade Policy Institute who is paraphrasing a statement allegedly made to his think tank by an unspecified staffer from Bonneville. But the actual quote from Wynn is quite specific:

“So when the wind blows, the dams stop generating electricity, and when the wind stops, the dams continue to generate electricity,” said Wynn. “So, in fact, wind power is just offsetting another renewable energy source. It’s not necessarily offsetting any fossil fuel generation.” http://www.katu.com/news/local/87439577.html

In other words, zero carbon wind power is displacing zero carbon hydropower in Bonneville’s service territory. Of course, if you start with a source of power that has no carbon emissions, then adding wind will have no carbon benefit. By cherry picking such cases as Bonneville, wind can be made to look bad to those who don’t have any information to make a reasonable judgment. It would be far more valid to look at how adding wind affects carbon emissions in the US as a whole, which gets about 70 percent of its electricity from the greenhouse gas emitting sources of coal and natural gas. The US electricity supply does not look anything like Bonneville’s.

Thus, this Bonneville case is an idiotic argument against wind. Sorry, but there is no kinder word for it.

But it is a very good argument against wind in the BPA control area. And it is a good example of how the claims made for wind by its salespeople and lobbyists don't quite hold up in the real world.

There are so many misleading statements in this thread of emails and articles, that it would be very time consuming to disprove them all. I am only picking some key issues to provide a sense of the scale of misrepresentation. The most amazing, is that Marin critics of the oil, gas and coal industry would first accuse MEA and wind developers of being pro-nuclear and pro-fossil fuel, and then include a full article by Robert Bryce (see below in thread)—one of his attack pieces on wind.

Bryce throws in “everything but the kitchen sink” in his attempt to “refute” wind power, piling bits of “evidence” taken out of context, to “prove” that wind a) causes noise, b) costs too much, c) does not reduce carbon emissions, and d) kills bats and birds. Some of these have a loose connection to reality. The wind industry is not, after all, spotless, and has significant problems which we have a duty to press wind developers to address. However, several major problems caused by our current reliance on coal, nuclear and natural gas electric power- causing catastrophic climate change, killing tens of thousands of people per year from air pollution, nuclear proliferation and radioactivity, and global energy wars— are not among the problems caused by wind, to put the discussion in the correct perspective.

(Briefly, again, there is a leap from noting the problems of our current energy use to claiming wind as a solution — that is a form of both ad populum and non sequitur logical fallacies. But we are not arguing about the existing problems; we are arguing about wind's usefulness.)

The low frequency whooshing noise from the rotating blades can be a problem for some people who live near large wind turbines. The facilities should probably be generally located at a good distance from people, and especially so for those who are sensitive to this sound. On the other hand, there are many noises that people accept as part of daily life that probably do not have worse effect than wind, such as the sound of cars and trucks on freeways and streets, construction equipment, the repeated humming and buzzing of electrical appliances such as air conditioners, refrigerators and transformers, the ground shaking and squealing sounds of railroads and light rail, etc. But the one that gets singled out for major action is, of course, windmills.

It is callous to disregard the continuing reports of people suffering ill effects from wind turbine noise. Noise regulations exist — often already inadequate — for noises we have had experience with. The unique sounds generated by giant wind turbine blades moving through different layers of air at tip speeds approaching 200 mph — and their physiological and psychological effects, from loss of sleep and stress to "wind turbine syndrome" — are still being researched and are clearly not adequately regulated.

As for cost, Bryce discusses the variable price of natural gas as the “determining factor” for whether wind power is competitive. However, he is misinformed, as apparently is his favorite source for information on wind cost and aesthetics: Texas fossil fuel billionaire T. Boone Pickens. At this point in time, natural gas is not the main expense for new natural gas plants in the US. Fuel may be the big expense for legacy plants that have paid down their initial investment, but not for new plants. Natural gas fuel becomes the main expense only when power plants operate in “base load” mode—running at steady output 24/7. Coal and nuclear plants operate that way, but most natural gas plants do not. When natural gas plants operate at fractional capacity, then the major cost is not the fuel, but the power plant. And while natural gas fuel prices are relatively moderate in 2011, natural gas power plants have skyrocketed in cost. Indeed, all new conventional power plants—coal, natural gas and nuclear power, have gone up dramatically in cost over the past decade. This is reflected by the Power Capital Costs Index, which reached 219 based upon a 100 starting index in 2000, meaning that a power plant built in North America in 2011 would cost more than double what it did in the year 2000. http://www.platts.com/RSSFeedDetailedNews/RSSFeed/ElectricPower/6253299

A natural gas plant built today and operating at, say, only 23 percent capacity, would produce electricity at about 13 cents per kilowatt-hour. This assumes the current cheap price for natural gas that Bryce proposes--$4.50 per million btu. Most modern wind plants can beat this cost of natural gas electricity—even without any tax subsidies. With tax benefits and offering lower early year prices in a escalating price contract, the first year price of wind may be as low as 4 cents per kilowatt-hour. Take away the tax credit and the first year price on a similar contract might go up to 5 or 6 cents per kilowatt-hour. Fixed price contracts might be 8 or 9 cents per kilowatt-hour. This is cheaper than any other new form of electric generation, including nuclear or coal.

Again, these are arguments as if there is a choice. Since a complete non-wind grid needs to be in place for times when the wind is not blowing sufficiently (or blowing too hard, or not in the right direction), you have to pay for both. So the comparison needs to be between wind plus gas versus gas alone.

... [Robert Bryce on Cape Wind costs] ...

Bryce’s analysis of the cost of natural gas power is closely related to his misrepresentation of the carbon benefits of wind. When modern “combined cycle” natural gas plants operate as base load—steady 24/7 at full output—they can reach efficiencies near 50%. Bryce argues that wind pulls natural gas plant out of operating as efficient base load to operating at part load to compensate for wind power. In partial or variable load, the natural gas plants may only operate at 35% or less efficiency, meaning the plant burns more fuel to generate each kilowatt-hour of electricity than when operating as a base load plant. Thus, if wind changed natural gas plant operations from base load to partial and variable load, the efficiency loss would increase fuel use and offset much of the carbon benefit of wind.

This assumes, however, that current natural gas plants generally operate in base load. That turns out to be quite incorrect for the general fleet of gas plants in the US. The vast majority of base load power in this country comes from coal and nuclear power, and to much a lesser extent from hydro and natural gas. In general, natural gas is used as a flexible resource mostly operating in partial and variable load—meaning it is already operating at lower efficiency in the vast majority of cases. This can easily be demonstrated with data about operations of US natural gas plants.

The US Government reports that as of 2009 there was 459,000 Megawatts of nameplate natural gas capacity. http://www.eia.gov/cneaf/electricity/epa/epat1p2.html Those plants generated 920 Billion Kilowatt-hours of electricity. http://www.eia.gov/totalenergy/data/annual/txt/ptb0802a.html If 459,000 Megawatts of power plants operated 24/7 year round, they would generate .459 × 8760 = 4020 Billion Kilowatt-hours of electricity. In other words, natural gas plants only operated about 920/4020 = 22.8% of their capacity. That means that natural gas plants in the US overall do not typically operate in highly efficient base load, but rather operate at their least efficient mode— the same as they would do for backing up wind.

In other words, Bryce’s argument that wind power reduces the efficiency of natural gas plants is highly misleading, since natural gas plants already operate at relatively low efficiency, and in this context wind power will make relatively little difference.

But the goal is to replace coal, i.e., base load. That could be done with very efficient combined-cycle gas turbines, effectively reducing carbon emissions by three-fourths. If wind is part of that effort, then half as efficient open-cycle gas turbines would have to be used, since CCGT isn't able to respond quickly enough to wind's variability. So the question is, again, what is the carbon effect of wind plus OCGT versus CCGT alone? Many analysts have found it to be no better and in some cases worse.

This also means that Bryce’s argument for “cheap” natural gas power— based on the current low fuel price— is wrong, since the low capacity utilization of natural gas plants means that the power costs are mostly driven by the cost of the power plant, not the cost of natural gas.

Bryce brings back another round of “bait and switch” comparisons on carbon benefit of wind power. He says:

“The American Wind Energy Association insists that the wind business ‘could avoid 825 million tons of carbon dioxide annually by 2030.’ (http://www.awea.org/_cs_upload/learnabout/publications/4136_1.pdf) That 825 million tons sounds like a lot. It’s not. In 2010, global carbon dioxide emissions totaled 33.1 billion tons. Thus, if the US went on a wind energy binge, and installed thousands of turbines in every available location, doing so might reduce global carbon dioxide emissions by about 2.5%. And that calculation assumes that global carbon dioxide emissions will stay flat over the next two decades. They won’t.”

It is a clever trick to make 825 million tons of annual carbon dioxide emissions avoided by wind power disappear into insignificance. This is actually a double bait and switch. First, if you go to the linked article, this savings claim is NOT from the American Wind Energy Association— it is a scenario from the US Department of Energy. The scenario is that 20% of US electricity comes from wind by 2030, which is equivalent to taking 140 million cars off the road and offsetting 20% to 25% of greenhouse gas emissions from the electricity sector. Not a trivial accomplishment. The second bait and switch is that Bryce compares the US wind scenario against global carbon reduction. This assumes that only the United States is installing wind, which is very far from the truth, and it compares apples to oranges. US wind power should be compared to US carbon emissions or you will make incorrect inferences about the result.

These criticisms are valid. But Bryce doesn't need to make 825 million tons look insignificant. That avoided CO₂ is already an imaginary projection based on theoretical equivalences, not real-world data.

Bryce goes on to the “bird and bat” argument. He cherry picks a study about bird kills at Altamont, considered by most wind experts as just about the worst case scenario for wind. Indeed, some wind advocates think that wind power should never have been developed at Altamont, as— in addition to being questionable environmentally— it is not a particularly good wind site.

Nevertheless, wind turbines do kill lots of birds and bats. Of course, so do many other things, such as power lines, buildings, cats, chemicals, and catastrophic climate change. It has been estimated that the average turbine kills about 2 to 3 birds per year. Getting all US electricity from wind would take about 1 million turbines that are 1.5 megawatts in size. That might kill about 2 to 3 million birds per year— assuming we got all of our electricity from wind, which no one expects ever to happen.

By comparison, communication towers are estimated at present to kill between 4 million and 50 million birds per year, and electric power lines may kill anywhere from hundreds of thousands to 175 million birds per year. http://www.fs.fed.us/psw/publications/documents/psw_gtr191/Asilomar/pdfs/1051-1064.pdf

And cats are estimated to kill hundreds of millions of birds per year, and more than a billion small mammals—including rabbits, squirrels and chipmunks— according to the American Bird Conservancy. http://www.abcbirds.org/abcprograms/policy/cats/index.html

All this is not to minimize the very real problem with birds and bats.

Actually, it obviously is meant to minimize the problem by comparisons irrelevant to the issue of wind's additional impacts.

Wind turbines do threaten certain specific species, such as raptors and certain types of bats. However, Bryce again goes out of his way to present selective data that skews the results against wind. He mentions that “In 2008, a study funded by the Alameda County Community Development Agency (http://www.altamontsrc.org/alt_doc/m30_apwra_monitoring_report_exec_sum.pdf) estimated that about 2,400 raptors, including burrowing owls, American kestrels, and red-tailed hawks – as well as about 7,500 other birds, nearly all of which are protected under the MBTA – are being killed every year by the wind turbines located at Altamont Pass, California.”

True enough, but he leaves out the most important finding of the study—the new “Diablo” turbines killed between 60% and 80% less birds than the old “Non-Diablo” ones. This means that the high level of bird kills at Altamont is a mostly legacy problem that can be greatly reduced with modern wind technology. Bryce is absolutely silent on this aspect of the Altamont study. Table ES3: http://www.altamontsrc.org/alt_doc/m30_apwra_monitoring_report_exec_sum.pdf

A reduction of an appalling death rate remains unacceptable. If bird mortality were no longer a problem, then why is the AWEA fighting new Fish and Wildlife guidelines that would make them comply with migratory bird treaties and eagle protection laws? Besides the 3,500 to 5,000 raptors estimated by ecologist Shawn Smallwood being killed annually at Altamont, other facilities also continue to report thousands of bird and bat deaths, e.g., at Wolfe Island, Ontario, and Maple Ridge, New York.

This takes us back to the question about why Bryce is chasing wind with a hatchet. What is his agenda?

Bryce, in his banner energy policy book “Power Hungry”, supports a vision very different than what anti-wind environmentalists claim to believe:

“The United States has built a $14-trillion-per-year economy based on hydrocarbons: coal, oil, and natural gas. We cannot— and will not— quit using carbon-based fuels for this simple reason: they provide the power that we crave. Nine out of every ten units of energy we consume come from hydrocarbons.

Power Hungry proves that what we want isn’t energy at all— it’s power. Bryce masterfully deciphers essential terms like power density, energy density, joules, watts, and horsepower to illuminate the differences between political rhetoric and reality. Then he methodically details how the United States can lead the global transition to a cleaner, lower-carbon future by embracing the fuels of the future, a future that can be summarized as N2N: natural gas to nuclear. The United States sits atop galaxies of natural gas, enough to last a hundred years. By using that gas in parallel with new nuclear technologies, America can boost its economy while benefiting the environment.” http://www.manhattan-institute.org/power_hungry/

Bryce also hates energy efficiency, and explains why in his book:

“He goes on to eviscerate the notion that the United States wastes huge amounts of energy. Indeed, the facts show that over the past three decades the United States has been among the world’s best at reducing its energy intensity, carbon intensity, and per-capita energy use.”http://www.manhattan-institute.org/power_hungry/

In other words, Bryce opposes the entire green agenda. Bryce is a big believer in nuclear and natural gas power— explicitly. He defends these sources as cheap and necessary, and in this context attacks solar, wind and even energy efficiency. Bryce is a key policy guy at the Manhattan Institute, an institution described in Sourcewatch:

The *Manhattan Institute* (MI) is a right-wing 501(c)(3) non-profit think tank founded in 1978 by William J. Casey who later became President Ronald Reagan's CIA director.

The Manhattan Institute is "focused on promoting free-market principles whose mission is to 'develop and disseminate new ideas that foster greater economic choice and individual responsibility.'"

"The Manhattan Institute concerns itself with such things as 'welfare reform' (dismantling social programs), 'faith-based initiatives' (blurring the distinction between church and state), and 'education reform' (destroying public education)," Kurt Nimmo wrote October 10, 2002, in CounterPunch. http://www.sourcewatch.org/index.php?title=Manhattan_Institute_for_Policy_Research

The Manhattan Institute, when it is not trying to destroy the environment and social programs, also likes to promote global energy wars. Perhaps its most famous contribution to public discourse was from David Frum, who left the institute to become a Bush speechwriter and coined the term “Axis of Evil”, a key concept that helped push the US into several international conflicts. The Manhattan Institute is big on “market competition”, also hard right style, which explains why it is so important to make the case that wind is dependent on welfare subsidies and “can’t compete” on the free market. Because if wind is lower cost without subsidies, Bryce and the other pro-fossil fuel and pro-nuclear folks decisively lose the battle on the conservative side of the political spectrum. Then they have to decide between dirty fuel and conservative principle.

So, if MEA and the wind developers are guilty of promoting wind and renewable energy, those who oppose wind are clearly siding with the authors of global energy wars, nuclear and fossil fuels.

Like Earth First, who have consistently recognized the predatory nature of industrial wind and led protests against construction of a facility in the mountains of Maine? Or the Zapatistas in Mexico supporting the Zapoteco farmers of the Isthmus of Tehuantapec against the theft of their land for a giant Spanish wind energy facility (the Zapotecos have written about "the imposition of neoliberal megacorporations destroying nature and our cultures")? Or the Adivasis of India, who are against being evicted from their forests so they can be mowed down for giant wind turbines? Or the diverse group of protesters camping out in northwest Denmark determined to save one of their last large forests from clearance for a giant wind turbine "test facility"? Or the anticapitalist antiwar Bread and Puppet Theater, who have been fighting big wind on Vermont's mountains? Or the established environmental advocate who lives off-grid and is leading the fight against industrial wind in Vermont?

Or do all supporters of wind power share the world view of all other supporters, such as T. Boone ("Swift Boater") Pickens; wind pioneers George W. Bush and Kenneth Lay of Enron (Bush was keynote speaker at the American Wind Energy Association convention in 2010); AWEA's own CEO, Denise Bode, former natural gas and petroleum lobbyist; anti-environment Christian fundamentalist Rick Perry; anti–environmental regulation lobbyist Frank Maisano of Bracewell-Giuliani, the spokesman for mid-Atlantic wind developers; nuclear plant builder and war profiteer GE, the country's biggest manufacturer of wind turbines (after buying Enron's wind division)? Or indeed, nuclear giant Electricité de France?

In fact, all of these supporters of wind are featured at Sourcewatch.org, and Counterpunch regularly reproduces Robert Bryce's work and has published an article by Nina Pierpont about wind turbine syndrome.

It is true that conventional energy companies are developing renewable energy projects, since many people in the energy industry see the writing on the wall. As Helen points out: “Wind developers are also oil and gas developers, they are one and the same.”

Well, the evidence shows that the opposite is true too: the wind opponents are supporters of oil, gas, coal and nuclear— they are one and the same. For, among renewable energy sources, wind is the closest to seriously challenge or displace fossil fuels in a big way. Strike down wind and you will set back renewable energy by 5 to 10 years. Of course, Bryce and Wind-Watch do not just want to get in the way of wind; their efforts also create roadblocks to other sources of renewable energy as well.

After the ad populum, non sequitur, red herring, and ad hominem efforts, now it's time for the straw man, or paper tiger. Robert Bryce does not represent all, or even most, opponents of wind. From that misrepresentation it is an unsupported leap to claim that "wind opponents are supporters of oil, gas, coal and nuclear" and "create roadblocks to other sources of renewable energy as well". Would Freehling similarly claim that opponents of big hydro are against other renewables? Rather than creating roadblocks, fighting the harm and waste of resources caused by industrial-scale wind is to the benefit of other renewables, such as decentralized small-scale vertical-axis wind. It would be more reasonable to argue that industrial wind itself has set back the cause of renewable energy with its aggressive encroachments on rural and wild land and habitats.

There is no choice about the fact that we are all— people who take pro-wind and anti-wind positions alike— enmeshed in a world controlled by conventional energy resources. But there is a big difference which side of this paradox you are on. Those who oppose wind because oil and gas interests are involved will leave us addicted to fossil and nuclear fuel, with no alternative energy source. That is not smart.

It was argued earlier that association with fossil fuel and nuclear interests adversely colored at least one writer's opposition to wind. But now it appears to be acceptable for wind proponents to consort with big energy. Clearly paradox, or real-world complexity, is allowed only for those who agree with Robert Freehling. Those with differing views must remain a caricature.

But to his final assertion, big wind is indeed big energy, and there is no sign that wind seriously threatens fossil fuels or nuclear. There is no justification for its novel impacts if it can not meaningfully diminish existing impacts from other sources of energy. At best, it might help drive the replacement of coal or even nuclear with natural gas (as required for back-up), but it would require less efficient gas turbines to be built than would be possible without wind. And then there's fracking.

To be pro-wind requires being pro–natural gas. Can we say therefore that to be pro-wind means to be pro-fracking? And to be pro-fracking is to be pro-Halliburton, and to be pro-Halliburton is to be pro-war ... (and former Halliburton division and war contractor Kellogg Brown & Root used to boast of being "in the vanguard of the development of offshore wind power in the UK" and still notes, "KBR has established itself as a key provider of services for the indispensable wind farm industry")?

Which side are you on, indeed.

"The menaced landscape"

Here is an excerpt from Robert Macfarlane's essay in today's Guardian about the "wind rush," in which he asks, "Wind farms? You may as well take a knife to a Constable":

'Wild and open spaces, for obvious reasons, are proving most attractive to candy-grab developers, and some of the most extraordinary mountain, moor and coastal landscapes in the British Isles - unique as a Turner or a Spencer - are currently menaced with ill-thought-out development proposals.

'The debate over wind power in Britain suffers, as do so many "countryside" issues, from a crippling polarity. Both sides are guilty of this, but let me take as a relevant example Polly Toynbee, who has voiced in these pages the standard leftwing, pro-wind position.

'Those who resist the spread of wind farms, wrote Toynbee, are Tory-minded "rural nimbyists", worried about the depreciation of their properties, or peddling "sob stories" about the visual pollution of their precious views. As climate change accelerates, these people are fiddling while the world heats up. They are, she ringingly concluded, "small, selfish and short-sighted".

'Toynbee should take a trip to Lewis in the Outer Hebrides. There, the energy giant Amec is pushing to establish the world's biggest wind farm. The local community is resisting as best it can. The farm is to be built on the northern part of Mòinteach riabhach Leòdhais, the Brindled Moor of Lewis - a wind-swept, hyena-coloured expanse of bog, waterfall, cliff and scarp. The moor is one of the world's last great peat-bogs, whose ecological significance has been compared to that of the Serengeti. It is under protected status as a UN Ramsar Site, a Special Protection Area, and a Berne Convention Important Bird Area: designations that Amec would steamroll. Its biodiversity and appearance make it the centrepiece of the Hebrides' £60m-a-year tourism industry.

'The moor, in its strange, wild beauty, is also at the core of Lewis's embattled Gaelic self-identity. For centuries, the people of Lewis have worked the moor. As Finlay McLeod of the Lewis protest group has put it: "Language and even a people may go - but the land was immutable, a last and lasting bastion for human sanity and belonging. Now, this itself is seen to be under threat."

'Amec has not, of course, come to Lewis out of the greenness of its conscience. It is there for the money. It hopes, with the help of government subsidies, to make about £68m a year if the farm is built. "Farm", though, is far too homesteadish a word for what will happen if Amec gets the go-ahead. It will erect 234 turbines, each nearly 140 metres high with a blade-span of more than 80 metres. (Imagine 234 structures, each more than twice the height of Nelson's Column, and carrying a propeller with a diameter greater than the length of a Boeing 747.) The energy will be carried off the island by 210 pylons, each 26 metres high, and their adjoining overhead lines. To service the turbines, 104 miles of roads will be built, as well as nine electrical substations. Lewis, it is clear even from these bald statistics, is to be turned not into a wind farm but a wind factory.

'The Lewis development will be irreversible. Wind turbines, it is often forgotten in the organicist rhetoric of the pro-wind farmists, require anchorage. One does not simply plant them like outsize seedlings. Each turbine will be counter-sunk into 726 cubic metres of concrete. In total, 5m cubic metres of rock and 2.5m cubic metres of peat-bog will be excavated. Such statistics render ridiculous Toynbee's claim that if another renewable energy source is found "the wind-turbines can be dismantled and taken away, no harm done".

'The Lewis project is a salutary case study. It reveals that an American-Puritan error - that wild land is waste land, there to be put to industrial use - is rearing its head. Wild places, it has come to be understood, are the "uplands" of civilisation: landscapes that can renew, console, and lift us in unique ways.

'Lewis's situation also reminds us of the spiritual, aesthetic, historical and ecological values that are put at risk when extraordinary landscapes are industrially menaced. These values are harder to measure, and harder to articulate than the hard numerical wattage of the turbines. But they are, unlike the wattage, non-transferable.

'A new study by the German energy agency, the world's leading producer of wind energy, has concluded that wind farms are an inefficient tool in our desperate battle against climate change. But even if this were not the case, certain types of landscape are too valuable to be turned into outdoor power-stations. The Lewis development is only the biggest instance: one grimly thinks of the 150-turbine development in Eisken on Harris, the planned development on the Sleat peninsula on Skye, and the "interconnector" - the 50m-high pylon-line required to carry the power from the wind farms of the Scottish west coast to the southern demand centres: a knife-slash through some of Britain's wildest vistas.'
