Revisiting Ocotillo
Author: Hales, Roy
Ocotillo, in Imperial County, has been inflicted by massive dust storms ever since 112 turbines were built around it. The desert surface was scraped clean of vegetation as a preparation for the project. Now there is nothing to hold the dust down. That’s not the only complaint. Since the project went online, less than two years ago: 3 turbines have had their gear boxes replaced, 9 turbines have had blade replacements a 173-foot-long-blade flew off one turbine Ocotillo residents have . . .

Author: Cryan, Paul; et al.
Significance: Bats are dying in unprecedented numbers at wind turbines, but causes of their susceptibility are unknown. Fatalities peak during low-wind conditions in late summer and autumn and primarily involve species that evolved to roost in trees. Common behaviors of “tree bats” might put them at risk, yet the difficulty of observing high-flying nocturnal animals has limited our understanding of their behaviors around tall structures. We used thermal surveillance cameras for, to our knowledge, the first time to observe behaviors . . .

Author: Various
On Tuesday 7 June 2011 NHMRC [National Health and Medical Research Council, Australia] conducted a scientific forum on the possible health effects of wind turbines. The forum provided an opportunity for NHMRC to hear the latest international scientific evidence and to engage with stakeholders over the range of issues for which there is public concern.
