The Bureau of Land Management (BLM) released a revised biological assessment for BrightSource Energy's Ivanpah Solar Energy Generating System, indicating the likely presence of a high density of endangered desert tortoises on the 5.6 square mile swath of public land.  The revised assessment is required because BLM and the US Fish and Wildlife Service determined that the number of tortoises impacted by the project would far exceed the 38 expected to be killed or displaced by construction and operation.  The assessment provides detailed estimates of the number of tortoises that might be killed,  harassed (marked, handled, etc), translocated (moved a distance away from where it was found), or held in quarantine.  Capture/Collect: BLM now anticipates capturing and collecting about 162 adult tortoises (animals that are 160mm or larger).   At least 60, but as many as 90 non-adult tortoises (smaller than 160mm) will be captured, although this represents o...

BrightSource Energy is offering to reduce its Ivanpah Solar Energy Generating System project by 12% in response to concerns about its environmental impacts, but will that be enough?  The company already exceeded the "take" limit established by the US Fish and Wildlife Service since it has displaced at least 49 endangered desert tortoises, as of February.  The project was only approved to displace 36.  According to High Country News , a second tortoise died on the site from heat distress as it attempted to return to its now-destroyed burrow in a bulldozed area of the project. The company now expects to displace or kill at least 140 tortoises if all three phases of the approved project are completed.  BrightSource Energy's 12% footprint reduction is likely inadequate, and an official interviewed by High Country News stated that the US Fish and Wildlife Service reserves the right to call "jeopardy" (limiting the project) if the current review determines that i...

In 1913, John Muir found himself confronting formidable forces that sought to entomb a pristine valley he had long fought to protect.  Congress, the White House, and San Francisco's water utility were eager to fill the beautiful Hetch Hetchy Valley near Yosemite with water that would supply a growing metropolis far away on California's coast.  Muir was an amicable, reasonable and open-minded naturalist, as portrayed in A Passion for Nature: The Life of John Muir by Donald Worster.  He did not fight projects for the sake of obstruction, but for sensible policy. There were other sources of water closer to San Fransisco, he argued, and it was needlessly accepted that the city's growth and thirst should not be tamed or made more efficient. Muir would not relent in his battle to save Hetch Hetchy, even when his own friends betrayed him.  Andrew Carnegie cast Muir's concerns aside and said: "John Muir is a fine Scotchman... but for all that it is too foolish to say tha...

The Department of Interior ordered BrightSource Energy LLC to temporarily halt construction on phases 2 and 3 of the Ivanpah Solar Energy Generating System since the project's impacts on the endangered desert tortoise have exceeded initial estimates.  The 5.6 square mile project is being built on public land and was approved by the Department of Interior and California Energy Commission in October after a hasty environmental review process.   Washington and Sacramento were intent on approving the project in time for BrightSource to qualify for taxpayer-backed financing.

During the environmental review last year, the Department of Interior estimated that the Ivanpah project would displace or kill 34 desert tortoises , which was still a phenomenally high number for a species that is in decline throughout its...

The California Supreme Court this month denied a petition by the Sierra Club that challenged the California Energy Commission's (CEC) inadequate environmental review for the Calico Solar power project.  A similar legal challenge by California Unions for Reliable Energy (CURE) was also thrown out by the court.  The Calico Solar power project was initially proposed by Tessera Solar LLC and approved by the CEC and Department of Interior last year.  Tessera Solar has since sold the project rights to K Road Power (aka K Road Solar), which is proposing to modify the 7.2 square mile project to use more photovoltaic panels to supplement Tessera Solar's disastrous SunCatchers .

The court decision is unwelcome news for concerned citizens who point to the Calico site's rich biodiversity and abundant desert tor...

BrightSource Energy LLC's plans to bulldoze 5.6 square miles of pristine desert habitat on public land is expected to displace or kill 140 desert tortoises.  The number of tortoises thriving on this land is a testament to the habitat quality and biodiversity on the site, but the environmental costs were ignored by the Department of Interior, headed by Secretary Ken Salazar, during a faulty approval process for the BrightSource's Ivanpah Solar Energy Generating System. Sign the petition now to tell Secretary Salazar to hault construction at Ivanpah and keep solar panels on rooftops, and off of tortoise habitat!
