Wind power effects... for Wolfgang

Nice to see you back Wolgang. Hope you are well.

I recall you have an interest in wind power. I though you might be
interested in the following link that describes one off-target effect on
bats.

Thanks Tim, doing as well as can be expected, I guess, for one in robust
good health and possessed of sufficient resources to pursue a few at a time
of a host of varied interests......time being the limiting reagent. I hope
you can say the same, or better.

This is very interesting. A few months ago I spent the better part of a day
talking to a DNR naturalist at the Horicon Marsh state wildlife refuge in
southeastern Wisconsin, who expressed a concern about the effects of a
proposed wind farm on the local bat population. Evidently there is a
substantial population that roosts through the winter in a nearby cave. As
he didn't say anything specific about what the machines might do to bats, I
assumed he was simply concerned about collisions. I was skeptical about
bats being unable to avoid the vanes under any conditions. The wind farm,
which covers a large area to the east and northeast of the marsh, is now
fully operational and I have not yet heard anything about the expected
casualties among birds and bats. However, I am aware, largely due to
monitoring a birding oriented listserve, of studies (both planned and
currently underway) using volunteers to make routine checks under the
turbines. The problem detailed in the story linked to above sounds highly
plausible and I'll be watching the studies I mentioned closely to see what
the results are.

Thanks for the heads up.

bat and bird impact statements are usually required as part of the
regulatory approval process for wind farms. i'll be interested in your
report and opinion of the experience up there. the wind farm i saw in
wyoming this summer was visually appealing on the windy plains and hills
in unitas county. while i have no doubt there are and will be bat
casualties, i doubt it will be of sufficient significance in most of the
areas wind farms will be located.

On a much smaller scale, the Dutch have done some tremendous work in
area of urban wind power. They have a helix type that mounts on
buildings and homes, generates 1.8 to 7.9 KW (depending on model) that
is quieter than a home air conditioner. I don't know anything about
the sonic levels driving bats nuts, but because of the shape, it
appears solid to birds and bats, reducing the chance of bird strike.
There are even areas in South America where they are mounting these on
cell phone towers to power the systems.

Lots of durability items to overcome but it looks like fun.
If'n we had a bit of wind here this would be a candidate for my next
failed energy project.

That's pretty neat, though I'm not sure how practical it is. Kinda noisy
too, it seemed. However, it might be just the thing I need for my planned
huntin' cabin on my uncle's mountain property.

As far as videos go I like this one just a bit better. It's short and to the
point.

I attended a conference a couple of years ago on windfarms. One thing
I remember is that cats kill 80 times more birds than windmills,
buildings with windows somewhere around 40 times.
Killing raptors was a problem as they sometimes fly backward relative
to the ground.and "back" in the blades.

USA and UK have one thing in common ....."U"

If you want to have another view on Bird casualties because of wind
farms Try Googling "Bird Casualty statistics in the UK" and you will
find some interesting articles there completely opposed to the
proliferation of wind farms in this green and pleasant land. Oh yes -
off shore ones as well.

Interestingly, I got a couple of emails on Thursday (while I was out of
state) concerning efforts to evaluate wind power generation from a number of
perspectives. Both of these came from people involved in birdwatching and
involved in various organizations related to this avocation as well as
others on broadly environmental themes. One of those emails concerned
proposals to set up windfarms IN the great lakes.......an idea I seem to
recall hearing something about a while back.

As Bill Grey pointed out, not everyone is yet sanguine about the birds and
whirling blades scenario. However, I suspect that even in these days of
increasing green consciousness, economics will come to dwarf other
considerations. In the meantime, while the currently available technology
is rather mature (enough so that major electrical power generation companies
are now large players in this nascent industry), there are vast untapped
resources available in as yet untested....hell, even undreamed
of.....designs, many of which will be safer for wildlife (assuming that the
risks, which are by no means yet clearly understood in enough detail, are
great enough to warrant greater protection) and various of which are likely
to be more efficient than current designs in differing sets of conditions.
In the near future, there is every reason to believe that new designs will
overcome many of the remaining technological hurdles. This is no pie in the
sky dreaming of miracle solutions. Rather, it is a sober reflection on the
vast technological and engineering forces that are currently available, and
the money which will soon become available in the search for replacements
for fossil fuels. Solar generation, on the other hand, MAY be feasible on a
large scale.....someday.....but most certainly not without some
unpredictable major technological breakthroughs.

At any rate, it's going to be fun to watch what happens in the next couple
of decades......and the smart money will be on wind.

I'll keep you posted on anything that crops up around here.
