[RE-wrenches] Wind Turbines killing birds and bats

Fri Jun 22 11:55:30 PDT 2012

Jason and Ryan,

Sure, I'll send a link to the monitoring site when it goes live. Ryan, I
agree with your opinion and wouldn't recommend vertical axis turbines for
any project that I can think of. Having a public monitoring site will help
reduce the back and forth debate - I suppose if people still want vertical
axis  turbines after seeing the data that will be their decision and of
course the installer's decision if they want to partake in the
installation. Maintenance and longevity issues of these turbines are
another really big concern past just the production issue. Having wind
turbines in such a public place has certainly garnered a lot of attention
to renewables in general and that part is good.

-August

Hello August,

Would you be willing to post the website URL for the vertical axis wind
turbines to the list when it becomes available?  It would be great for
potential vertical axis owners (and installers) to see.

Thank you,
