The downside of windmills

I have been reading a lot lately that windmills have a serious downside: killing birds, including endangered ones. Also bats. I don't see how birds and bats can be protected and view this as another human in-humanity. see clip:

Article abstract:

Quote:
Based on operating performance in the United States and Europe, this study offers an approximate calculation for the number of birds killed per kWh generated for wind electricity, fossil-fuel, and nuclear power systems. The study estimates 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.

 

From a birdwatcher's blog:

Quote:
Here's what we know: researchers have found that on most modern wind farms, each turbine kills an average of 2.3 birds each year (read the latest NWCC report here*).

So if they want to put a monster 500 turbine wind farm in your county, that might kill an estimated (reaching for the calculator...) 1150 birds a year. Still sounds like a lot?

It is estimated that the average house kills around 10 birds a year that smack into its nice picture windows. The average outdoor cat may kill 10 birds each year as well. There are about 100 million homes in the U.S. and maybe that many cats as well. Are you doing the math? We're looking at something like a billion birds killed by windows, and another billion killed by cats, each and every year. With an estimated 20 billion birds in the U.S. each fall, windows and cats may be killing about 10% of all birds every year.

* I replaced the original (dead) link with a new one which will soon (I hope) connect to an updated report. - M.S.

Thanks M. Spector -- the whole "wind farms kills birds" thing is definitely blown out of proportion when you look at the relative affects of the other industries.

I went to a community meeting about windmills the other day. It was fairly well attended, with a lot of frustration being expressed about lack of clarity.

There were a few people there from areas where windmills are already operating. It seems that some people get sick from living near those huge industrial windmills and are having trouble selling their homes, because of a drop in the realestate vaues of their homes on account of the proximity to the windmills. Also I got the impression that the Ontario government is attemting to take away local council's right to restrick these projects.

Germany has over 19,000 wind turbines and a much greater population density than Canada.  Have the Germans run into health problems?

The Danes get 20% of their power from wind turbines.  What sort of sicknesses do they suffer?

well, there was one elderly woman that lives near the clear creek windfarm. She is experiencing hearing loss, she said it feels like having her ears full of cotton balls. Her hearing recovers when she leaves the area, but it takes longer and longer to recover. She also has chest pains, which was initialy thought to be heart problems but no heart problems where found. She had more problems but do not recall what they were. Sleep deprivation seems to be a big problem also. It all might have something to do with low frequency vibration that those mill emit.

I remember there being a segment on CBC Radio's The Current a few months back on the subject.   Ontario residents living near windmills claimed that there was an incessant low frequency hum that was destroying their lives.

Is this for real? I've lived in houses most of my life and have never known a bird to fly into a window? 10 a year? That doesn't sound right.

It does happen.  Just because the bird doesn't drop dead immediately after impact doesn't mean it won't die later with broken bones.

Would this be the same people like the Paris suburb where a Cell Antenna went up and people complained about the health issues and sickness and cancer before it was revealed that it had not even been turned on during the period they were complaining?

Take heart. Linda Hasenfratz's auto parts giant, Linamar is going to to making the nacelles for a revolutionary made-in-Canada, 2 mgw wind turbine that is expected to be able to generate electricity at lower wind speeds. And people will be employed here in making them -. They are big suckers, but there must be somewhere in the middle of Lake Ontario that they won't bother anyone (Scotland puts them out in the North Sea).

I am not sure if we solve anything by making light of these peoples problems with windmills or cell towers. I am convinced that for them the problem is very real. And that it is something we will have to deal with.

Some are afraid of hights, others of spiders, open spaces, small spaces, buttons, flighing, etc,etc. I have seen people get violently ill from blood and gore, motion sickness. These are very unpleasant experiences to the people involved and literaly make them sick. Pharmaceuticals might block some of these experiences, but as far as I know provide no cure. I am not sure if they could be psychosomatic ilnesses, by that I mean illnesses that have an origine in the mind, what ever that is. If these real reactions have the origine in the mind then some of these illnesses might have a cultural component, since culture shapes so much of our mind.

Missed your post George. They are big indeed. the ones proposed for this area will be in the range of 460ft.

We've talked about this before.  The last time I attempted looking up stuff on line about low frequency or infra sound coming from windmills, it seems the windmill industry had studies, but are keeping them under wraps.  But they say they don't pose a problem. 

I'm guessing of course, based on some things I've seen and things I've read, but I think these low frequency sound waves can bother some people, and not others.   I wouldn't dissmiss claims out of hand, anyway. 

I find it irksome, however, because this is all measureable and testable, we should know deffinatively by now. 

Denmark wouldn't have as many complaints because their wind farms are in the North Sea, far away from Danes. 

It's too bad Toronto isn't located near a large body of water where windfarms would be close to the users, but far away enough not to encroach on people's real estate values or health.  

I guess we'll just have to put them in rural backyards.  Nothing to be done about that.

A friend has built a home made windmill to generate electricity -- very inspiring.  I want to build and install a windmill for power generation for our home.  I am sure there are some downsides:  cost, time, safety concerns.  The upsides: return on investment, possibly not having to pay a hydro bill, ever again.  Not contributing to the wellfare of large corporations.  Being a role model for others -- showing that things like this are possible.

Sometimes I think Ontario is making a mistake by installing windpowered electric generators. Most power is probably used in the Windsor to Quebec corridor. Storing electricity is a big expensive problem. Why not built a big pipe from Lake Ontario to lake Erie. Built a whole bunch of windmills on top of this pipe to pump water from Lake Ontario into Lake Erie and use that extra water in Lake Erie to run electric generators in the Niagara gorge  as needed. I have not done the math, but suspect that a six to twelve inch level variation in Lake Erie would represent a huge storage of electrical capacity.

Any chance they (windmills) can be modified to emit frequencies that will drive squirrels away? I so totally promise not to be NIMBY about them if they can guarantee that.

Just get a few cats, they will not catch all, but certainly will keep the numbers down to tolerable levels. It is probably cheaper then see your property value go bown by 30 percent or so, when one of these 460ft structures grace your back yard. Also when the windmill operator goes bankrupt you will not get stuck with a lean against your property, as some farmers have had the pleasure of experiencing.

The cats are afraid of this bunch and, living on the prairies, there is a shortage of mink, marten, lynx etc. to keep that particular type of rodent under control. I keep hoping coyotes will hurry up their evolutionary progression and develop the ability to pursue them into trees.

I'm sure it does happen.  But 10 times a year for each house?  I've never actually seen a bird hit a window.  Ever.

Windmill problems.

Wind turbine syndrome.

If these people are imagining their problems, they're getting their doctors to imagine them too.

Maybe it's an average. One house I lived in birds would fly into one particular window frequently. Most would just be stunned and eventually fly away, a few I actually picked up and set in small box on the deck where they either recovered or died. Occasionally one would hit hard enough to leave feathers behind. We finally got some window stickers that looked like spider webs and they stopped.

Growing up just outside Ottawa in a big house with two large picture windows set in an angle opposite each other, we had lots of bird strikes as birds tried to fly through. The solution was to keep the curtains closed on one side.

After reading this, I'm thinking it's more of an educated guess.

Quote:

But even such small glass kills can add up to big trouble, believes ornithologist Daniel Klem of Muhlenberg College, in Allentown, Pennsylvania. Between 100 million and 1 billion birds die in glass collisions every year in North America alone, Klem estimates. At the very least, that's an average of one bird a year slamming into each of the roughly 100 million homes, apartment buildings, office towers, schools, and storefronts that dot the American landscape.

Quote:

Such anecdotes, along with statistics from an array of studies, ultimately became the basis for Klem's glass-kill estimates, which he first published in 1990 in the Journal of Field Ornithology. He admits that some of his assumptions-such as a key estimate that 1 to 10 birds die per year at the average structure may be "a bit soft."

If you shell out for some black sunflower seed (cheaper than the larger striped variety, which is feeding more people this year, a mennonite farmer tells me) you have happy squirrels and ALL the birds, all too fat to be an aerial problem.  (And I would not want to live within hearing distance of a wind turbine.

 

And Tommy :

"It's too bad Toronto isn't located near a large body of water where windfarms would be close to the users, but far away enough not to encroach on people's real estate values or health. "

...you're puttin' us on with this geographically challenged observation. It doubles as your comment on not just property values but also human values in the Big Smoke. As observed from a smaller community tired of Hogtown's carryin' on... Subtle.

Reefer, possibly it just is an educated guess. I'm not sure if it really matters that much to the overall argument. The stats on cats are likely more accurate but particularly telling is the report that M. Spector posted which looked at bird kills related to other forms of energy production. Yes wind turbines kill birds but relative to a whole lot of other human related activity they pale in comparison. The numbers on bats are even more difficult to get a handle on. I went to talk given by a bat biologist who said that they suspect that they do kill bats but getting exact figures and even studying it is very difficult due to the nature of bats themselves. Of way more concern is the mystery fungus that's ravaging bat colonies as we speak, is spreading geographically each year and is pushing some colonies numbers to extinction levels. To use the word decimation and total destruction to describe whats happening is not hyperbole. If they don't get an handle on what's causing it and figure out if there are human caused reasons for this and/or figure out if there's anything that can be done to stop it then in many areas there just won't be a whole lot of bats to hit or be killed by anything. I do think the potential health affects are an aspect that warrants some serious study and don't think it's something that should be just dismissed as some sort anti-windfarm nimbyism. Whatever the reasons there is something going on. I know a few people who have developed some of the health problems that the articles talked about and they aren't the type of people to just make stuff up and neither were they against the turbines when they went up. My parents live within the shadows of a recently built windfarm and my father did develop heart problems last year. Though neither of us are blaming the turbines for it as there are likely other factors involved it is difficult to completely dismiss it as some sort of woo when some of your neighbors start complaining of similar ailments or similar symptoms are being reported from other places. There is enough I think to at least place some serious consideration on the possibility. My Dad is someone who is likely to correlate the cause of his problems with anything but the turbines as overall they both have no problems with them and are supportive of building them. They were one of the first households to say they were fine with it when the proposal was first put out. Most of the people in that area were and that project in particular went up with very little conflict from the residents. I personally hope there isn't any correlation either. I do have some concern about it though because from a completely personal viewpoint if there is indeed some sort of provable connections then it will devastate my family. What it means is that a five generation family home becomes virtually unlivable as I expect that if it comes to and either or situation that metal will win over flesh.
