Perhaps it depends on the distance from them, or maybe the design of the
blades. Either way, noisy or not, they are still a blot on the landscape,
and IMHO, a huge waste of resources for the relatively small amount of
power
that they generate.

Do you have evidence for that, one way or the other?


And actually, who's to say that by 'stealing' the wind, they
don't cause some 'butterfly effect' elsewhere ? :-) Little of what
man does actually has a zero effect on his environment ...

The same thought has crossed my mind, too. But they're unlikely to have a
significant effect, for roughly the same reason that humans are unable to
deliberately modify the weather -- it takes too much energy.


Nuclear reactors don't bother me, much. Nuclear waste does. Do you know what
a pebble bed reactor is? It appears to have the potentional to end all the
problems with nuclear energy, but nobody's doing much about it.
