When Education Becomes "Misuse"

BrightSource Energy does not want you to see photographs of birds burned by its solar power tower technology, according to an excellent article in the Press-Enterprise.  The company's archaic solar design involves thousands of giant mirrors heating up a cauldron at the top of a tower (taller than the Statue of Liberty) to generate steam.  The company also uses natural gas to keep the boilers warm, so it is not entirely "clean" energy, unless you think fracking is clean.  The air above the field of mirrors can become super-heated, and burn birds' feathers and damage their eyes, according to wildlife experts and a study at a similar facility in the 1980s.

The photos were presented in a special closed door session of the California Energy Commission (CEC) proceeding for BrightSource's proposed Hidden Hills Solar project, only after the CEC issued a subpoena to get them.  According to a BrightSource statement to the Press-Enterprise, the company is afraid of that the photographs would be "misused" if entered into the public domain.  In other words, people might actually know more about BrightSource Energy's impacts on wildlife.  Check out the article.

The threat of burned feathers and eye damage is only one aspect of the project's impacts on birds, since collision with the "heliostat" mirrors may turn out to be the highest cause of mortality.

No, these are not BrightSource's "secret" photos.  This is an excerpt from Avian Mortality at a Solar Energy Power Plant, a study by Michael McCrary and others at a solar power tower plant in California that found these birds burned by the super-heated air generated by the mirrors focusing the suns rays at central points above ground. The study looked at a 10 megawatt solar power tower plant in the 1980s.  BrightSource Energy's Hidden Hills project would generate 500 megawatts and cover nearly 5 square miles with mirrors.

How Many Plants Species in the Desert?

Would you expect that California's desert hosts gives the redwood forest a run for its money when it comes to plant biodiversity?  It's easy to take the desert for granted when all you want to do is zoom through it on the highway and get to your destination. But you are passing by an amazing and biologically diverse ecosystem.  There are at least 2,450 native plant species found in California's desert, according to a great article by Chris Clarke on desert life , posted at KCET. If you want to learn more about our amazing deserts, join Desert Biodiversity, a new organization dedicated to exploring, respecting and defending the deserts.

Mowing Vegetation as Mitigation: Trump Administration Practice Goes Unchallenged

Image
The Trump administration is again touting the practice of mowing thousands of acres of desert vegetation as environmentally-responsible, despite a preponderance of evidence to the contrary.  The draft environmental review of the Yellow Pine Solar project in southern Nevada claims that vegetation mowing - as opposed to bulldozing - will yield positive outcomes that are highly doubtful.   This positive framing of the construction practice misleads the public and decisionmakers and ignores decades of scientific research regarding the impacts of mechanized disturbance on desert wildlands.  According to the draft environmental review: "Mowing is becoming the standard on large site-type ROWs to prevent permanent impairment of public lands (as mandated by FLPMA) and in lieu of off-site mitigation... Mowing methods are designed to help preserve soils, biological soil crusts, soil seed banks, native perennial vegetation diversity and structure, and cacti and yucca species, and to resist

The Absurdity of the Cadiz Water Export Scheme

Image
The Department of Interior this month reversed a policy to make it easier for the Cadiz company to pump billions of gallons of water from an ancient Mojave Desert aquifer - killing off natural springs that wildlife depend upon - to ship that water to the lush landscaping of Orange County.   Cadiz still has other hurdles in its way, but the company's tenacity and willingness to line the pockets of politicians could spell doom for Mojave wildlife. Cadiz Calls it Conservation The Cadiz company has a contract to export nearly 16.3 billion gallons (yes, that is billion with a 'b') a year for 50 years from the Mojave to the Santa Margarita Water District ( SMWD ) in Orange County.  The Cadiz company claims that it will only pump water that would otherwise evaporate from a dry lake bed and that the aquifer will naturally recharge from rainfall, leaving no significant impacts on wildlife or groundwater levels.  According to Cadiz propaganda, this isn't a water export sche
