How Much is Too Much Heat for Birds?

Image
In testimony submitted in advance of California Energy Commission (CEC) evidentiary hearings scheduled for the end of this month, the CEC staff estimates that the impact of heated air above BrightSource's proposed Palen hybrid solar and natural gas project may result in as much as 2.5 times more bird deaths than at the BrightSource's Ivanpah hybrid project (I use the term "hybrid" because Ivanpah will burn nearly 525 million standard cubic feet  of natural gas, annually.  Palen will burn at least 728 million standard cubic feet of gas, annually.  Unlike photovoltaic solar projects, BrightSource's power tower design needs fossil fuels to warm up the boilers that also convert the sun's energy into electricity). This peregrine falcon was found emaciated at BrightSource Energy's Ivanpah solar project and later died. Note the clear singing of the feathers likely caused by the intense heat generated by BrightSource's mirrors. Photo from the Nationa

Coolwater-Lugo Transmission Line: A Horse Following the Cart

Image
Southern California Edison (SCE) is suggesting that interconnection of Abengoa's Mojave Solar project is the primary reason it needs to build the nearly 75 mile Coolwater-Lugo transmission line through the Lucerne Valley, according to the Daily Press , even though Abengoa told the California Energy Commission (CEC) and Bureau of Land Management (BLM) in 2010 that these transmission lines would not be necessary.   Misrepresenting the need for new transmission lines during the CEC and BLM review of the project would have allowed Abengoa to downplay the costs and environmental impacts associated with approving the project.  The Coolwater-Lugo transmission line is likely to cost ratepayers at least 509 million dollars, and bring bulldozers and transmission towers to mostly undisturbed desert. Without the Abengoa Mojave Solar project as an excuse,  SCE probably could address other distribution needs - such as relieving the transmission bottleneck at Kramer Junction - by upgrading ex

First Solar Begins Ecosystem Destruction in Ivanpah

Image
First Solar has begun construction on the 2.6 square mile Stateline Solar project - one of the company's two additional solar projects in the Ivanpah Valley - after a judge turned down a request for an injunction by the Defenders of Wildlife .   First Solar is also expected to begin bulldozing desert habitat for the Silver State South project, which will destroy over 3.7 square miles of tortoise habitat on the Nevada side of the Ivanpah Valley.  Both projects will destroy some of the best quality desert tortoise habitat in the Mojave Desert and, more insidiously, likely sever a habitat corridor linking separate populations of the tortoise. A tractor begins clearing intact desert habitat for First Solar's Stateline project in the Ivanpah Valley.  In the initial phase of construction, the project has already displaced at least 16 desert tortoises, including one that was pushed out of its burrow by a bulldozer and happened to survive.  Photo from construction monitoring report

BrightSource Underperforming; Adds Fossil Fuels

Image
The California Energy Commission (CEC) last week signaled support for BrightSource Energy's request to increase natural gas use at the Ivanpah Solar project to nearly 525 million standard cubic feet each year to help heat steam when the sun is not shining.   BrightSource's request to burn more natural gas underscores the difficulty the company has had with its experimental power tower project, even as the company proposes building the even larger Palen Solar project east of Joshua Tree National Park.  The difficulties at Ivanpah - increased fossil fuel use, impacts on birds and bats , and poor operational performance - undermine the company's argument that the CEC should approve Palen because of the project's proposed renewable energy and storage benefits. The photo and text above were submitted by CEC staff as part of a supplemental staff assessment in the Palen Solar project proceeding regarding glare.  The Caltrans Aeronautics Division Chief was also part of th

Industry Influence Limits Discussion Space

Image
Protecting intact ecosystems from unnecessary destruction should be considered a core objective for  people concerned with the fate of the planet and our ability to live sustainably, yet the climate crisis has prompted various facets of the energy industry - from fossil fuel interests, to utility companies, wind turbine manufacturers, wind project developers, solar panel makers, and solar panel installers - to manipulate how we discuss the solution to the climate crisis.  Just as any industry tends to lobby and influence the parameters of debates that might affect their profits (e.g., the tobacco industry and public health, and the gun industry and gun ownership regulation) the energy industry will similarly seek to influence how we define and pursue sustainability.  So it is imperative that environmentalists participate in this discussion with a critical eye, questioning not just the information they are given, but also questioning the boundaries placed on the discussion and how those

Sierra Club Joins Opposition to Palen Solar Project

Image
The Sierra Club filed a petition this month opposing BrightSource Energy's plans to build the nearly six square mile Palen Solar power project in the Colorado Desert between Joshua Tree National Park and Blythe, California.  Although the California Energy Commission (CEC) denied the Sierra Club's petition to formally participate in evidentiary hearings regarding the project, the Sierra Club's public opposition adds to the persistent environmental concerns expressed by desert conservationists, including the Center for Biological Diversity and Basin and Range Watch. [click on image to expand] The Palen Solar power project would blanket nearly 6 square miles of Colorado Desert habitat with thousands of giant mirrors and two power towers taller than the Washington Monument.  Based on initial observations of other solar project in the desert, the Palen Solar project is likely to attract and kill a significant number of migratory and resident birds. What makes the proposed

Wildlife Viewing at the Preserve this Weekend

Image
If you are free on Saturday, June 7, head out to the Mojave National Preserve for an opportunity to learn from wildlife experts and a chance to see bighorn sheep and other desert denizens.   I had the fortune of visiting the Desert Studies Center at Zzyzx last month, and the even greater fortune of viewing desert bighorn sheep along the rocky slopes that meet the Soda Dry Lake.  Although the landscape is mostly dry, natural springs in the area provide a critical water source for the sheep and habitat for the endangered Mohave tui chub.  I would highly recommend heading out to this event early, and consider camping in the Preserve that night if you want to prolong your escape into the desert! These bighorn sheep were photographed just above the Desert Studies Center, which lies in the Mojave National Preserve at Zzyzx.
