Windfarm sickness spreads by word of mouth, Australian study finds
March 19, 2013 10:36 AM   Subscribe

Sickness being attributed to wind turbines is more likely to have been caused by people getting alarmed at the health warnings circulated by activists, an Australian study has found. Complaints of illness were far more prevalent in communities targeted by anti-windfarm groups, said the report's author, Simon Chapman, professor of public health at Sydney University. His report concludes that illnesses being blamed on windfarms are more than likely caused by the psychological effect of suggestions that the turbines make people ill, rather than by the turbines themselves.

Spatio-temporal differences in the history of health and noise complaints about Australian wind farms: evidence for the psychogenic, “communicated disease” hypothesis. (PDF)
Background and objectives: With often florid allegations about health problems arising from wind turbine exposure now widespread in parts of rural Australia and on the internet, nocebo effects potentially confound any future investigation of turbine health impact. Historical audits of health complaints across periods when such claims were rare are therefore important. We test 4 hypotheses relevant to psychogenic explanations of the variable timing and distribution of health and noise complaints about wind farms in Australia.
Setting: All Australian 49 wind farms (with 1471 turbines) operating from 1993–2012.
Methods: Records of complaints about noise or health obtained from wind farm companies regarding residents living near 47 Australian wind farms, expressed as proportions of estimated populations residing within 5km of wind farms, and corroborated with complaints in submissions to 3 government public enquiries and news media records.
Results: There are large spatio-temporal variations in wind farm noise and health complaints. 31/49 (63%) of Australian wind farms including 17/34 (50%) with turbine size >1MW have never been subject to noise or health complaints. Western Australia has seen no complaints. Only 120 individuals across Australia representing approximately 1 in 272 residents living within 5km of wind farms appear to have complained, with 81 (68%) of these being residents near 5 wind farms which have been heavily targeted by anti wind farm groups. About 1 in 107 of those living near turbines > 1MW have ever complained. The large majority (82%) of health and noise complaints commenced after 2009 when anti wind farm groups began to add health concerns to their wider opposition. In the preceding years, health or noise complaints were rare despite large and small turbined wind farms having operated for many years.
Conclusions: In view of scientific consensus that the evidence for wind turbine noise and infrasound causing health problems is poor, the reported spatio-temporal variations in complaints are consistent with psychogenic hypotheses that health problems arising are “communicated diseases” with nocebo effects likely to play an important role in the aetiology of complaints.

There was a whole back and forth in the BMJ about this issue last year which you can only access as a subscriber, unfortunately. Chapman wrote in his disagreement with a BMJ editorial (this, I think) about wind farm noise written by two British researchers whose work is regularly quoted as gospel by anti-wind farm groups.

They'd be fine if they built mobile phone masts into the windmills.

The psychology of this is so well understood, these days - you can make a good case for it being the same basic driver as that behind the early modern witch hunts - and having researched it for a while

I'd be surprised if there was any new technology which hadn't attracted the fear in some form or another. The curious counterpoint is that things which do have subtle yet pervasive effects on health, such as food chain muck-ups, environmental contamination from internal combustion and plastics, cigarettes and so on, are often not taken seriously by the public for ages.

People, eh?

At least in the UK, my anecdotal understanding of wind farm refuseniks is that it they are typically a self-appointed group of nimbies who don't much care how the next generations will get power and dress up house price concerns variously as health, environmental, economic reasons.

I'm not an expert, but I have commissioned a couple of studies into the economics of wind power. It amuses and infuriates me in equal measures when self appointed experts tell you about the exhorbitant "cost" of wind farms but then can't tell if they mean installation costs, running costs, external costs, lifecycle costs.

They don't know whether those costs are rising or falling as the technology matures. They don't know how the economics of power generation change if the price of oil continues to rise. But they're bloody sure that wind power is expensive because.... they look ugly and they don't work when there's no wind and some sandal wearing environmental hedge fund charlatan has convinced the government to put these windmills round the country and when all we need is more good old power stations like we used to have.

Birdkill and radar effects seem reasonable enough concerns that should be examined without the woo and nimby stuff.

There have been quite a few studies on birdkill, the metadata suggests about 2 bird deaths per turbine per year, with variations depending on siting. There was a fairly large amount of work when turbines started shifting offshore, and new sites like the large Dogger Bank site in the North Sea will likely end up as one of the areas with the most environmental surveys anywhere. Offshore wind along with tidal stream and wave energy is also likely to mean large amounts of research into the possible impacts of noise, electromagnetic fields, etc on fish, pinnepeds, elasmobranches, benthic environment, etc.

Wind turbines do interfere with radar, this is undisputed (TV too - line of sight from a mast to the population centre it serves equals planning rejection in the UK). In the UK, a large percentage of planning applications for turbine siting will automatically be rejected on the say so of the RAF. The wind sector sites away from RAF bases and radar paths accordingly. There is some work underway which will hopefully apply software to lessen the number of sites which are rendered ineligible as a result.

Seriously. They want to install wireless hydro-meters here in my part of my Quebec, which has led to ZOMG THEY WILL KILL US articles in the op-ed parts of the newspapers and on the radio. La Tribune, in response to the encroaching hysteria, even published a graph that showed you should fear your mobile and your microwave more than you should fear these things. And last night it took a five-hour public city council meeting before Sherbrooke said, "You know what? We're doing this. Wireless meters for all! Now go home so we can all get some sleep."

Ironically, if nimbies wouldn't freak out about the possibility that wind turbines might be perceived to negatively affect prices, then they're far less likely to negatively affect prices. It's a self-fulfilling prophesy of destroying your own home value by your own actions.

Home values are increased by having a view of a windmill, and wind turbines could be the same thing (they are definitely a beautiful sight to huge numbers of people), and someday might. The main difference is that turbines represent the future instead of the past.

Oh the best is when they say that wind turbines only work about a third of the time, and show that the nameplate capacity is a "lie". They declare this with some bluster, as though happy that they've discovered the dirty secret of wind energy.

I assume it's a line-of-sight issue - if the "eye" of the radar is situated on the ground, lower than the top of the turbines, then the turbine crops the field-of-vision by half a degree or so, which might only be 300 feet when looking at objects above the turbine, but objects on the far side of the turbine, way out in the distance will have to be progressively higher to not be occluded.

Large turbines are in the 600+ feet range now. Line of sight is one issue. I think (but will stand correction) that part of the problem is that the blade speeds can be pretty fast, ie 100m/s, and this throws up false readings. The UK apparently has specific issues with wind turbines and radar due to its geography that have been harder to solve than elsewhere in Europe.

is this tied to the "fan death" panic in South Korea? It kinda seems like the same thing

In the Canadian incarnation - where it's usually referred to as "wind turbine syndrome" - it's not at all like the South Korean fan death thing.

What happened in Canada was that the province of Ontario passed North America's best renewable energy legislation, a feed-in tariff based on the German model that provided huge incentives for new RE installations.

Owing to the way the tariff was structured and the biases of the lumbering old bureaucracy formerly known as Ontario Hydro, however, the quickest and easiest installations to get approved were huge, rural, industrial-scale windfarms. (In Germany, solar installations led the way and local partnership/ownership of even large windfarms is common, smoothing over much of the NIMBYism.) Developers leaped in to sign leases with local landowners and started plopping down 5-MW turbines by the dozen in very short order, with abysmal local consultation and no local investment other than the land leases. People got agitated, consternated, concerned.

As the situation grew tenser, the junk-science peddler Nina Pierpont started making the rounds, and the provincial Conservatives - who'd opposed the Green Energy Act to the point of near-hysteria and saw an easy wedge issue to mop up votes in rural ridings - took to aiding and abetting any argument that suggested the act was bad for Ontario.

All of a sudden, reported cases of "wind turbine syndrome" skyrocketed. It was an epidemic! (As one rural municipal councillor told me at a conference, "This wind turbine syndrome's the damnedest thing. If you've got wind turbines on your property, you're not affected. But if your neighbour has wind turbines and you don't, you're sick as a dog!")

My take has long been that the symptoms people were reporting might be real, but that they were a product of the sudden spike in stress in their lives and the sort of hypochondria being described in this Australian report. Really, really hope the whole junk science mess of it will soon be dead and buried with reports like these.

In everyday interactions spoiling somebody's view is considered obnoxious: the person in the row in front at a concert who won't sit down, the person who walks in front of the camera just as a photographer is about to snap an elaborate group photo. If somebody spoils the view from our house then that can intuitively feel still more obnoxious: the neighbour's extension will block our view of the mountains and it won't be gone tomorrow. What can surprise people is that society's sympathy is generally on the side of the blocked person in the concert - but it (in the form of planning law) is usually on the side of the neighbour when it comes to their plans to build: one does not own one's view in planning terms. The case of a planned wind farm is more like the neigbouring extension than anything else - but with the important different that the neighbour also picks up a large large sum of money for the privilege of hosting the turbines. Given all this alone (and laying aside all arguments about the effectiveness of turbines, subsidies and everything else) I am not surprised people get upset.

But I do seem to recall seeing a study saying that the (very real) nocebo effects tend to vanish when communities in the line of site are given a share of the payout. That seems a reasonable policy to me.

Wind turbines do interfere with radar, this is undisputed

You can see it yourself. KLOT, the WSR-88D weather radar for Chicago. As I write this, the radar is in clear air mode (VCP 31) so there's more noise -- planes, birds, etc.

But if you zoom in and look between Pontiac and Ottowa, you'll see two blobs that never move, and if you SW of the I-88 sign east of Stirling, you'll see three more. These are all wind farms in Northern IL.

For fixed structures, like the tall buildings in Downtown Chicago, the radar return doesn't change much, so they can filter that out. But the blades on a wind farm are turning, so they don't put out a reliable signal. The other way to tell fixed structures is by the doppler -- they don't move, so no doppler. But windmills, again, with the moving blades defeat that filter as well.

It is an issue -- it only affects the lowest sweep of the radar, but that's the sweep that can see the farthest.

No, the sympathies seem consistent to me - the person who paid for a ticket to a seated concert and won't sit down is analogous to a person who paid for land and builds a structure that ignores its intended zoning. There is more civil recourse in the later case, granted.

Conversely, if a person sitting in the seat in front of you happens to be tall, that's something you have to grin and bear, that's life in a society of a people, and the the same view is taken regarding a person buying a property in front in you to build their house.

If you want an empty seat next to you on the airline, you either pay for that seat, or you accept things if you don't buy it and it turns out the plane is full.

The sympathy lying with the person whose view is being blocked in the theatre as opposed to with a wind turbine falls down in another key area. The person who wants to preserve their view will want to continue to use electricity. Continued generation of electricity will require someone has to live close to a wind farm, or a coal power station or a nuclear power station.

gompa: In Germany, solar installations led the way and local partnership/ownership of even large windfarms is common, smoothing over much of the NIMBYism

Your underlying point is correct but solar did not take the lead. Germany had a meaningful tariff to support wind from 1990 and the initial bulk of German renewable energy was wind power. Solar only really grew in Germany from 2000 onwards, it only broke through 100MW in 2001, at which point there was 6GW of wind. It was community and farmer owned wind and so was generally accepted. The German state and states helped by adopting a proactive approach to planning. The Danish approach was similar but also had rules that you could only own a small share of generation and had to live within a certain radius of the turbine you had shares in. This also aided acceptance - "your own pigs don't smell". The Danes also required counties to come up with a forward plan for where turbines could be sited.

Oh, man, I had never seen/thought of that before. I would lose my fucking mind. There is a smoke stack a half block south-west of my home and occasionally--once a month, maybe?--the wind will blow the smoke in our direction and blot the sun out in flickers and stutters all afternoon. And that drives me mental. I'd for sure grow a brain tumour of consternation if I had to endure windmill flicker over my home every day.

On the other hand, this seems like a tremendous opportunity to do good by creating research that shows that windmills make people smarter, richer and better lovers.

The farmer-owner thing with wind in Germany is really interesting. They're all over the place in northwest Germany where i travel for work and the system seems great. Your local farmer puts up a tiny segment of land for a turbine and gets some remuneration to support the farm. It barely interferes with farm operations at all. Pretty much win-win, I would say.

How useful is radar 300 feet from the ground?

Just reiterating, the radars they use do sweeps at different angles to cover the different layers of the atmosphere in order to build a three dimensional image of the weather. A sweep that is nearly parallel to the ground will catch any rain that is falling, but it won't catch the giant thunderhead 40,000 feet in the air that has yet to begin raining.

Imagine a flashlight in a dark field. If you point it straight ahead, you will see people, but not critters. If you point it down, you will see critters and holes in the ground, but you'll miss the tree branch that you are about to smack your head into. Same idea.

Sovacool (Energy Policy 37 (2009) pp2241–2248) suggests "that wind farms and nuclear power stations are responsible each for between 0.3 and 0.4 fatalities per gigawatt-hour (GWh) of electricity while fossil-fueled power stations are responsible for about 5.2 fatalities per GWh. While this paper should be respected as a preliminary assessment, the estimate means that wind farms killed approximately seven thousand birds in the United States in 2006 but nuclear plants killed about 327,000 and fossil-fueled power plants 14.5 million. The paper concludes that further study is needed, but also that fossil-fueled power stations appear to pose a much greater threat to avian wildlife than wind and nuclear power technologies."

Who hates wind turbines more than anyone?

Oil Corporations: Traditional Energy Providers; Bottom line.


What happened in Canada was that the province of Ontario passed North America's best renewable energy legislation, a feed-in tariff based on the German model that provided huge incentives for new RE installations...

Germany doesn't quite have those big Traditional Energy Providers sitting right beside the P.M., unlike Ottawa..

The recent former premier of Ontario, Dalton McGuinty, went against the tide, like a boat against the current. He brought in North America's best renewable energy legislation based on European concepts, which I think is a good idea. (He was also trying to catch up with the kilowatts of Quebec's environmentally questionable James Bay Hydroelectric Project).

Nimbyism (different Nimbys from the wind farms, actually) bit Dalton hard when he replaced old coal plants with gas plants, and locals near the new gas plants squeaked enough to get the opposition political parties involved. Then he jiggled locations for these plants in order to win a pretty tight election... but then he also had problems with various dumb scandals by greedy underlings in the health sector, and then he took out his frustration randomly on the education sector... so is Dalton like the Prometheus or Icarus of Energy in Ontario for the 21st Century?


Energy is a big deal. Who provides it. How much it costs. How much are you willing to pay?

There have been quite a few studies on birdkill, the metadata suggests about 2 bird deaths per turbine per year, with variations depending on siting.

So ... one outdoor moggie ~= 50 wind turbines.

"The results were certainly surprising, if not startling," says UGA researcher and lead author Kerrie Anne Loyd. "In Athens-Clarke County, we found that about 30 percent of the sampled cats were successful in capturing and killing prey, and that those cats averaged about one kill for every 17 hours outdoors, or 2.1 kills per week. It was also surprising to learn that cats only brought 23 percent of their kills back to a residence." - http://www.mnn.com/earth-matters/animals/blogs/outdoor-cats-are-prolific-killers-study-finds

Lynda Barry on wind turbines. As much as the evidence seems to be piling up that turbines are harmless, I also find it hard to believe that Barry is just imagining things.

Why? This whole post is about people starting to imagine symptoms when they hear about them.

Why? It's pretty obvious a lot of other people are. Is it because she has some special skill/ability that isn't obvious? Because she writes hyperbole with skill? Because she's a noted and talented cartoonist? Just curious, because there is precisely nothing in that article that isn't debunked in the FPP and endlessly repeated in every other OMFG Windfarms, OMFG Cell Towers, OMFG HAARP, etc., etc. articles.

So if my home electric usage is 1kW for my 100-year life, I use ~.9GWh of electricity; if it all came from wind, then I was the cause of death of .4*.9 = .36 excess bird deaths, and if it was from coal 5.2*.9=4.7 excess deaths? I feel like I must have slipped a decimal place somewhere, because that might as well be nothing. About on par with the carnage from a bucket of KFC.

Windmills and brain cancer? Windmills and disease? When will they start to examine the obvious link between windmills and stupidity?

is this tied to the "fan death" panic in South Korea? It kinda seems like the same thing

There is a shocking preponderance of unscientific magical thinking here in Korea (including but not limited to things like 'fan death' and nonsense like talking nicely to onions (or whatever) makes them rot slower or makes plants grow faster), but no, there is no connection. There are quite a lot of wind turbines here, and as far as I know, not a lot of hysteria about them.

Jepler: I am not sure how system losses are taken into account in those figures but those are the direct impacts. Bear in mind everything you buy will also be bathed in the blood of sparrows. Embedded bird deaths one might say.

This isn't to say the wind industry is a blameless beacon of community-first policy - a nearby town has a 300' tall paperweight because the company who sold the town on a community turbine also sold them a bum gearbox. Of course they'll replace it... for half a million dollars. The town does not have a half a million dollars, the turbine was supposed to be generating electricity and cash by selling juice back into the grid; massive overhauls after less than 5 years of operation were not part of the deal. Insurance on the structure won't cover "minor" mechanical repair, and the maintenance contract won't cover "major" mechanical repair. So the damn thing is idle, and the town will be paying it off with tax revenue rather than electricity revenue for the next 20 years unless they take another bond to fix the gearbox and get better insurance and maintenance contracts.

stavros, to be fair, there's lots of magical thinking here in N. Am. as well. We just keep it in the kitchen.

I would be really interested in a post about this.

I've been doing wind turbines for 20-ish years. No new issues have come up in that time. Sure, some of the understanding of long-range noise propagation has improved, but also - watt for watt - new turbines are quieter than old ones. The anti-wind echo chamber is amazing; they all use wordpress.com blogs, and I'm pretty sure they're using auto-posts from RSS feeds so that all the groups (I use that term loosely; some of the groups are actually individuals) appear to be producing a united, massive and fast-acting front. The cross-pollination between the Ontario groups and the Australian groups produced a 24-hour news battering against wind energy.

One of the surprisingly large opponents of wind power are power workers. Apart from maintenance crews, wind farms don't employ thousands of people. They dispatch and shut down as the weather changes. In the words of a certain computer company, wind turbines just work.

There are other less overt anti groups, such as the Renewable Energy Foundation. They come up with delightful bits of misinformation like their report that shows that turbines get less efficient as they get older. If you dig through the data yourself, you realise that it's actually new turbines being so much taller than old ones that makes them perform better. It's a bit like saying that computer gets slower as they got older, because your Vic-20 is now 30 years old and a bit rubbish compared to a quad core.

Shadow flicker can be a thing, but we can design around that. We can either make a flicker map of the area, and make sure turbines don't cast long shadows on houses, or use light sensors and time of day restrictions that will stop the turbine at certain times is the sun is bright and clear and the wind is from a certain direction. It's standard on some vendors' equipment.

But yeah, Chapman's work codifies what we knew all along. Hysteria feeds on itself. It's why I have this on my office wall.

I think this is not quite right, there is a fair amount of evidence that renewable energy provides more jobs per MW installed, though as the technology becomes more mature the number of jobs per unit declines, though not below FF levels. Wind is a bit mroe than gas or coal and PV is a lot more jobs. Biomass is more by a factor of 2-3. The problem for current power workers is that RE jobs, as with the technology itself, will not be centralised where they live, they will be distributed.
