NEW WIND DESIGN TO PROTECT BIRDS

Researchers, wind energy companies seek more "bird-friendly" turbines on Altamont Pass

"…[T]he Altamont Wind Resource Area (AWRA)… -- one of the largest concentrations of wind farms in the country -- is in the middle of a decommission of 4,000 old turbines that use 1970s and '80s technology; nearly all will have to be removed or replaced by 2018. The world's most heavily studied area for wildlife impacts could also be the proving ground for a new type of turbine…[Ogin Inc. is seeking] approval to install 40 of its ‘shrouded’ turbines in the Sand Hill area to test its theory that the turbine's unique design will help prevent golden eagles, red-tailed hawks and other species from colliding with the blades, hopefully reducing deaths…The key is the shroud -- two concentric covers around the blades -- which the company says not only make them more efficient than older turbines, but also less accessible to approaching birds and bats…The Golden Gate Audubon Society in Berkeley is supportive of the study…” click here for more
