Medication data show no link between wind farm and "syndrome"

A survey of four towns in Victoria and South Australia has shown that the symptoms of “Wind Turbine Syndrome” -- a collection of adverse health effects that have been associated with low frequency noise from wind turbines -- are experienced no more frequently near wind farms than in comparable areas. The research, lead by Head of the University of Adelaide Discipline of Medicine Professor Gary Wittert, is yet to be published, but was covered by ABC News here, and featured in Monday’s Four Corners program, “Against the Wind.”

Wittert used Pharmaceutical Benefits Scheme (PBS) data to map the prescriptions of medications for sleeplessness, blood pressure and other cardiovascular conditions, and found that these conditions are no more prevalent within 10 km of wind farms at Waubra, Yambuk, Snowtown and Hallett Hill than in control areas with similar demographics. This defies the expectations of those who argue that prolonged exposure to high levels of low frequency noise and infra-sound can cause adverse health effects up to 10 km from a wind farm.

Wind Turbine Syndrome, which encapsulates a range of symptoms such as sleeplessness, high blood pressure, migraines, depression, tinnitus and nausea, was defined by American paediatrician Dr Nina Pierpont in her 2009 book of the same name, based on a voluntary study of 10 families (38 subjects) in 5 countries. In Australia, the campaign has been led by Dr Sarah Laurie, an unregistered GP from South Australia and the Medical Director of the Waubra Foundation. Dr Laurie’s research so far (summarised here) is based on interviews with 60 subjects, mostly residents living near wind farms.

The worrying findings of Pierpont and Laurie have so far been based on small samples of voluntary respondents, and sceptics are quick to point out that no residents with wind turbines on their property have made health complaints. This year’s federal Senate inquiry into The Social and Economic Impact of Rural Wind Farms cited literature reviews by National Health and Medical Research Council (NHMRC) in 2010, and by the American Wind Energy Association (AWEA) and Canadian Wind Energy Association (CWEA) in 2009, which both found no suggestion in the existing research for a positive link between wind farm noise and adverse health effects. Neverthless, the Inquiry and NHMRC did recommend further research.

Based on Laurie’s findings, the Waubra Foundation calls for health studies in the form of residents’ personal health journals and ongoing noise monitoring. These studies may yield valuable data, but will take many years to deliver viable scientific conclusions. But if vibration and low frequency noise from wind farms cause adverse health effects, any number of historical data records should reflect the systematic increase of these symptoms in the area of wind farms. As Wittert points out, we have up to 25 years of experience of living and farming around wind farms in Australia, and over 30 years internationally:

[...] if you think about the density of turbines in some European countries, such as Germany and Scandinavia, one would expect that if there was that much infrasound causing people and animals to vibrate that you would notice some significant effects. There is no data coming out of Europe that there are any changes in lambing, in milk production, in the quality of beef or in any other form of agricultural products that involve livestock. Nor are there any reports of significant health effects coming out of any of those countries.

If exposure to wind farm noise was the cause of these severe health effects in humans and livestock, historical records should be sufficient to show the link. While acting as an expert witness for wind farm developer Acciona, Wittert conceived of an elegant method for quantifying the geographical and historical prevalence of these health effects. Before undertaking the study, he explained his planned methodology to the Senate inquiry:

Senator ADAMS—You were talking earlier about trying to get independent people. How would you go about that? You were talking about a 10-kilometre area for doing your PBS investigation. How would you find a cohort that was large enough within that particular area to do these other observations and have independent witnesses?

Prof. Wittert—That is why GIS methodology is probably the optimal way of doing it if you can get enough pool data. Let me give you an example. Let us say there were 2,000 dwellings within 10 kilometres of a set of turbines and I knew that the turbine was erected in 2007 or 2008. PBS could give me data over 4½ years. So let us say I can get data from 2006-07 and I know that there are a certain number of prescriptions being issued for blood pressure medication. Over the period of the next few years I could then determine whether there were any change in the provision of blood pressure medication. If I could do the same thing across two, three or four areas where there were turbines erected, I could compare those to other areas of similar demographics where there were no turbines erected. I would now be able to compare across time within an area where there is a turbine. I could compare across time in an area where there is no turbine. I could then compare between the two areas. I could do that across a range of conditions—assuming, of course, that there is a prescription issued for that condition and it is diagnosed. What you can then use is geographic information systems to overlay things like distance to the nearest doctor, a whole bunch of socioeconomic data, the age profile of the population et cetera.

In contrast with the dozens of voluntary respondents featured in Pierpont’s and Laurie’s studies, the PBS data account for more than 10,000 subjects near four different wind farms. This kind of geostatistical study removes questions of selection bias, and allows for quantitative comparison within each community before and after the installation of the wind farm, and against comparable communities without wind farm developments.

Given the health complaints of dozens of residents near wind farms, the NHMRC and Senate inquiry, alongside the Waubra Foundation, are right to call for more research. But the aims of that research, its methodology and the tone of its discussion in the community, deserve some scrutiny. Wittert’s study, based on historical data collected for an independent purpose, shows no link between proximity to wind farms and prevalence of the expected symptoms of Wind Turbine Syndrome. The methodology is straightforward, and the academic report is unlikely to be inflammatory. By contrast, the kind of small scale studies carried out by Pierpont and Laurie -- based on interviews and personal health diaries -- privilege the most dramatic accounts of aggrieved residents, and provide powerful anecdotes for emotive media coverage.

This focus on the subjective and emotional often pushes the actual science to the end of the article, without advancing knowledge about the issue. At the height of the Senate inquiry Professor Simon Chapman of the University of Sydney vented some frustration with a cutting analysis at the ABC's The Drum. In this context, Wittert's study is a welcome contribution to the scientific discourse. As he said to the Senate inquiry, “there is also an awful lot of anxiety being generated, and it would be nice to have some objectivity and rationality around it.”

The Australian IT article on Cyclopic Energy

As we mentioned last time, Cyclopic Energy has been attracting some attention in the last few months for our use of cloud computing services to deliver complex wind simulations for the wind energy and construction industries.

So we were pleased when Ian Grayson, a leading Australian IT journalist who has been covering cloud computing closely, contacted Rick Morgans to research an article featuring us for The Australian. “Super computers when you need them” is a special report in today's issue of The Australian IT, and we think it sheds some light on the practical aspects of our business, explaining the tools we use to deliver very large, high resolution wind simulations in a matter of days.

This has been a good opportunity to catch up with Ian Grayson's broader coverage of cloud computing, and other IT news, both in The Australian and at his blog Hydrapinion.

BRW Features Cyclopic Energy on Cloud Computing

Cyclopic Energy has attracted significant attention in recent months as an example of a new Australian company making innovative use of cloud computing. Jeanne-Vida Douglas of BRW recently spoke to Rick about the benefits of on-demand supercomputing facilities:

“When Rick Morgans and Damien Leclercq set out to turn what they knew about engineering, modelling and wind into a business in 2008, they knew their success would depend on being able to punch above their weight and deliver highly professional services to some of the largest companies in Australia.”

The article focuses on the advantages of cloud computing to small, smart businesses: low costs and high performance, with a high degree of flexibility. When needed, Cyclopic Energy spin up a battery of high-performance instances which execute large Computational Fluid Dynamics simulations on demand. We use these dynamic and scalable supercomputing services facilitated by Amazon Web Services to deliver high quality wind modelling and analysis services at low cost.

As Rick says: “it's enabled us to compete with much larger companies and deliver high-fidelity simulations we would never otherwise been able to afford. What it means is we can grow without spending on extra computing power.”

You can read the full article in the April 21st edition of BRW, or electronically here (with a subscription).

Wind Farms: What Causes the Angst?

Former rural GP Dr Sarah Laurie has fast become the spokesperson for the anti-wind movement. She has embarked on a mission to travel the country roads of Australia, spreading the message that low frequency noise and vibration from wind farms will destroy the health and livelihoods of the local residents. The subsequent angst has consumed otherwise peaceful communities with suspicion, anger, and psychological stress. That some people genuinely feel affected by nearby wind farms is accepted, but to this date the causes remain largely unexplained.
Dr Laurie's roadshow recently made a stop in a seminar room at the University of Adelaide, where the audience was largely made up of researchers, academics, engineers and students. Despite attempts at giving the presentation a scientific feel, the poorly constructed argument - an emotional mix of hearsay, frightening anecdotes presented as scientific evidence, misrepresented research papers, and heart warming pictures of babies and cute animals - did not stand up to the ensuing questions. Most were met with admissions of insufficient knowledge, absence of proper studies, and a lack of evidence.
Dr Laurie will probably keep travelling around the country, raising the spectre of Wind Turbine Syndrome in communities who trust a well meaning country doctor, thus seeding deep anguish and psychological stress on fertile ground. Interestingly enough, the symptoms of the so-called Wind Turbine Syndrome that Dr Laurie describes are similar to those of the deep anguish and psychological stress that her presentation will understandably cause. Is it ethically right for someone who claims to be a caring medical practitioner to disrupt entire communities based on anecdotes and unproven allegations? One would think not. Unfortunately, the AMA is in no position to regulate this; Dr Laurie is unregistered.
If you ever come across Dr Laurie or any of the Wind Turbine Syndrome apologists, do yourself a favour: seek an alternative, professional opinion before making up your mind. The alarmist, bite-sized message is easy to understand and quite effective. Actual facts are generally more nuanced and boring, but at least they let you sleep at night.

Innovate SA Focuses on Cloud Computing

At Cyclopic Energy, we use cloud computing to mobilise supercomputing resources on demand. This allows us to run large Computational Fluid Dynamics simulations in volume and at short notice, without maintaining expensive computing infrastructure locally. This has revolutionised the way we deliver high resolution CFD analysis, and we're constantly exploring ways the cloud can make our services faster, cheaper and more efficient.

Cloud computing promises opportunities for new and existing services. To facilitate new innovation in this area, Innovate SA has dedicated a Product Commercialisation Case Study Seminar to helping South Australian companies understand how the cloud can advantage their business. Our Technical Director, Dr Rick Morgans, will be speaking about Cyclopic Energy's innovative use of cloud computing at the Seminar on 4 April.

Cyclopic Energy announces new capabilities

Cyclopic Energy is pleased to announce the addition of visual impact and shadow flicker studies to its range of services.

When our clients are developing a wind turbine installation, particularly in the urban environment, there is often a need to understand its visual impact for nearby observers. In response to this need, Cyclopic Energy recently developed analysis tools to quantify wind turbine visibility and shadow flicker in the area around an installation.

Based on the same detailed 3D models we build for our CFD simulations of wind flow over buildings and complex terrain, we can now map the apparent size and visibility of wind turbines over an area, accounting for local topography and foliage.

An important consideration when siting wind turbines is the frequency of shadow flicker, which occurs when the rotating wind turbine casts a moving shadow over an observer. Cyclopic Energy models the maximum hours per year (assuming it's sunny) where the wind turbine's shadow is cast, producing maps of annual frequency over public areas and building façades.

We're always excited to improve our tools, and we're constantly working to develop services for wind power and the built environment. Read more about our services here.

Building mounted wind turbine failures in Hobart

On 11 August two of the four large wind turbines mounted on the roof of the Marine Board building in Hobart suffered an impressive (but fortunately, it appears, not catastrophic) failure. For some of the news coverage read The Mercury (here and later here), ABC News (here and here), and the Sydney Morning Herald (here). This is of course a very damaging case for the small wind industry, particularly in the building-mounted sector.

We would like to take this opportunity to re-iterate Cyclopic Energy’s position on building-mounted wind turbines:

  • Wind flows around buildings are extremely complex and require detailed measurement and modelling in order to minimise excessive structural loading on the turbines and the building structure. This involves a detailed understanding of the effects of flow acceleration, turbulence, wind shear, and yawed winds.
  • Wind turbines need to be selected carefully, and it is important to research the history of the product, previous similar installations, and compliance to standards. This is of critical importance in urban installations, where structural failure is likely to have grave consequences. The mere fact that the machines are commercially available, and therefore come by law under warranty, is insufficient to guarantee reliability.
  • Inspection and maintenance regimes should follow a conservative schedule, again because of the possible consequences of catastrophic failure.
  • If these basic precautions are taken, building-mounted wind turbines can be made to operate safely.

Please contact Cyclopic Energy to discuss how we can assist you to develop a safe and successful wind turbine installation.

Policy Adjustment to Stabilise REC Prices

The Federal Government has responded to feedback from industry, announcing the Enhanced Renewable Energy Target (ERET) Scheme. The changes, to be affected from January 1 2011, will isolate incentives for utility-scale renewables from those offered to households who invest in small wind and solar systems.The adjustment is a move to stabilise the price of Renewable Energy Certificates (RECs), which has fallen sharply following the introduction of Solar Credits scheme for small generation units.

The Renewable Energy Target (RET) Scheme is a market-based mechanism to drive Australia's electricity supply toward a target of 20 per cent renewable energy by 2020. Under the scheme electricity retailers must meet a mandatory Renewable Power Percentage (RPP) each year, a requirement they can fulfil by purchasing sufficient RECs at market price; each Certificate represents 1 MWh of renewable energy.

The Solar Credits scheme, introduced in June 2009, applied a 5-times multiplier to the RECs deemable against the first 1.5 kW of small wind, solar or hydro systems. An unintended consequence of this market-based system, which was designed to replace direct Federal rebates, was a severe drop in the price of RECs and a subsequent loss of investor confidence in large-scale renewable projects. In recent weeks both Pacific Hydro in South Australia, and Roaring 40s in Tasmania, had announced holds on wind farm projects as a direct result of falling REC prices.

The Enhanced Renewable Energy Target Scheme stabilises the REC market by separating incentives for small generation units (SGUs) from the market system which applies to utility-scale generators and retailers. The Large-scale Renewable Energy Target (LRET) will continue trading RECs at market price, and will meet the majority of the renewable energy target by 2020, while RECs earned by small generation units will be sold at a fixed price of $40 per MWh under the Small-scale Renewable Energy Scheme (SRES).

The adjustment is expected to restore confidence in the REC market and re-start progress on utility-scale wind farms, while increasing incentives in the small wind and rooftop solar markets. To learn more about the Enhanced Renewable Energy Target Scheme, read the Department of Climate Change Fact Sheet.

Tax rebate for SA wind projects

The South Australian Government has introduced a new incentive for investment in large scale renewable energy projects in the state, announcing tax rebates for companies investing in wind farms and solar projects above 30 MW in scale. A payroll tax rebate of $1 million for wind farms, and up to $5 million for solar projects, will be given for labour costs related to direct on-site construction starting after July 1 2010. The tax exemptions will be available for four years, driving investment in utility-scale renewables toward South Australia's goal to generate 20% of its electricity from renewable sources by 2014.

Premier Mike Rann announced the plan yesterday from Copenhagen, where he is chairing a states and regions committee on climate change as part of the ongoing UN summit.

Detroit Small and Community Wind Expo a success!

Our Directors Damien and Rick spent a week at Detroit's Small and Community Wind Exhibition and Conference, where they made contact with key manufacturers, distributors and consultants in North America's vibrant small wind industry. The American Wind Energy Association recorded a 78% growth in the US small wind market over 2008, and with on-going federal and state incentive schemes in the United States and Canada, North America is an exciting market to be involved with.

Unlike commercial scale wind farms, small and mid-scale wind installations often go ahead without detailed analysis of the local wind resource. Cyclopic Energy has identified a strong potential for our services in wind resource assessment and wind turbine micro-siting in the North American market, and we look forward to working with suppliers and consultants to develop quality wind power solutions internationally.

New South Wales switches to gross Feed-in Tariff, includes small wind

The New South Wales Government has announced its new Solar Bonus Scheme, covering small wind turbines and replacing the previous net metered model with a gross Feed-in Tariff. Under the new scheme all electricity generated by wind or solar systems with rated capacity under 10 kW will earn a 60 c/kWh tariff, not just the excess power exported to the grid. The new Solar Bonus Scheme has extended coverage in NSW to small wind turbines up to 10 kW, a significant shift from solar-only incentives. The Solar Bonus Scheme will last for seven years, providing significant incentives for the small wind industry in the state.Read more about the NSW Government's Solar Bonus Scheme here.

The announcement makes NSW the second government in Australia to adopt a gross Feed-in Tariff, after ACT; all other states have announced or implemented net Feed-in Tariff schemes. The South Australian Government is currently reviewing its Solar Feed-In Scheme, which recently saw installed capacity of eligible solar PV systems reach 10 MW; one consideration is extending the tariff to include small wind turbines, a move which would be a major boon for the small wind industry in South Australia.

Wind turbine installations require expert siting: Solar Shop Australia stops selling residential wind turbines

Solar Shop Australia, a major provider of residential-scale renewable systems, has stopped selling wind turbines. Citing the necessity of on-site wind resource monitoring and the difficulty of turbine siting, Solar Shop explained that, unlike solar systems, "wind power requires careful consideration and specific site information in order to ensure optimal performance." Read the statement here.

Cyclopic Energy agrees. Detailed site modelling and on-site wind monitoring are the foundations of our approach, and should be the primary concerns of anyone considering an investment in on-site small wind generation. Read about our robust approach to wind resource measurement and wind turbine siting here.

What to expect from building-mounted wind turbines

Our article in The Fifth Estate uses some back-of-the-envelope calculations to estimate the contribution a building-mounted wind turbine installation could reasonably be expected to make against the energy demand of a typical office building.

Interest in building-mounted small wind generation has increased drastically in recent years, and many turbine manufacturers and property developers are eager to drive the industry further with a number of high-profile investments in the build environment. These are exciting projects, and Cyclopic Energy has an interest in seeing the successful growth of the small wind industry - including, where appropriate, building-mounted installations.

In the excitement, however, some optimistic claims have been made about the expected performance of building-mounted wind turbine installations. We believe that no one's long-term interests are served by making unrealistic estimates of the contribution of roof-top wind turbines.

The Fifth Estate is an online magazine providing news and networking with a focus on the sustainable built environment.
