Luckily for the birds using habitat along the Colorado River, part of the bird migratory corridor known as the Pacific Flyway, BrightSource Energy has temporarily suspended its plans to develop the Rio Mesa Solar project.  The California Energy Commission (CEC) staff, wildlife officials and conservation groups expressed concern during environmental review that the project's proposed location and design -- involving the solar power tower technology -- puts birds at risk of collision with the project's thousands of mirrors, or risk of eye damage and burning from superheated air above the project.  A screenshot 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 also found that most birds probably died from collisions with the mirrors.  The study f

Element Power appears to have cancelled its plans to build a wind energy project on desert wildlands near Pioneertown and Joshua Tree National Park, according to BLM records.  The company drew the ire of conservationists and fans of the desert when it installed meteorological testing towers, and signaled interest in eventually installing giant  turbines that would stand over 420 feet tall.  Element Power in December submitted a request to relinquish its wind testing right-of-way due to poor wind resources in the area.

Energy company Iberdrola Renewables is still looking for a way to bulldoze a portion of the Silurian Valley, a quiet desert landscape nearly 15 miles north of the town of Baker, California.  Iberdrola as of last year had plans to build a wind energy project in the Silurian Valley, but likely conflicts with Department of Defense training and testing activities forced the company back to the drawing board.  According to BLM records, Iberdrola is now considering building a large solar project, which probably would sidestep conflicts with Department of Defense interests. Iberdrola has converted over 10 square miles of its wind energy application to a solar right-of-way application, according to the BLM records, although the company has not given up on its wind application.  The company may not plan to use all 10 square miles of the right-of-way application for the solar project, since the current application only describes a 150 megawatt facility, which would require a much smaller footp

The owner of the stalled Calico Solar project is asking for a deferral on nearly 600,000 dollars in rent owed for reserving a large swath of public lands.  You might remember the long saga of the proposed Calico Solar project, which will destroy up to six square miles of desert habitat in the central Mojave Desert if California and Bureau of Land Management (BLM) officials give K Road Power the green light to convert the previously approved plans from solar thermal to photovoltaic technology.   The short version is that the initial project plans were approved in late 2010 despite environmental concerns, but the previous owner went bankrupt and sold the project to K Road Power, which decided to alter the plans enough to warrant further environmental review. After K Road acquired the project, Southern California Edison withdrew its agreement to buy power from it, and now K Road is stymied by unspecified issues with transmission lines.  The project would require expensive new transmiss

It took my sister and I about an hour to remove enough trash from a patch of Joshua tree and pinyon juniper habitat in the west Mojave Desert to fill five garbage bags full of trash, not to mention a few card board boxes that did not fit in the bags.  This is one of the edge effects that population centers have on the desert -- trash that either blows away from the owner or dumped illegally (I'll address the latter in a follow-up post).   The trash can pose a fire hazard, trap or choke some wildlife, and is a blight on the landscape. Pick a place, set aside an hour or two, bring gloves and some trash bags, and get out there and clean. But think about how quickly a few volunteers can make a difference  If you're interested, you can always grab a pair of gloves and some trash bags and clean up your neighborhood.  It is quite fulfilling to look back on your favorite desert spot as you haul away the trash.   If you want a more structured project, check out the Mojave Desert

In a rather strong and thorough letter, the US Fish and Wildlife Service (FWS) in November asked the Bureau of Land Management (BLM) to reject First Solar's Silver State South solar project in the Ivanpah Valley, reiterating FWS concerns that the project will reduce or eliminate a critical linkage for the threatened desert tortoise.  FWS' letter preceded a joint letter submitted in December by eight different environmental groups asking the BLM to suspend approval of any additional projects in the Ivanpah Valley until a conservation plan is in place, indicating that BLM decisions impacting the Ivanpah Valley so far have underestimated its biological importance. FWS Comments on Silver State South Solar FWS's asks the BLM to work with the applicant to modify the layout of the project if it is not possible to reject the project altogether, suggesting the alternatives already analyzed by BLM do not offer a sufficiently wide habitat linkage. Human development to the west,

Some solar companies have insisted on having wide access to remote and intact desert habitat to build new solar facilities, lobbying against land management policies that would restrict industrial-scale energy development on lands of ecological importance.  The Bureau of Land Management and California Energy Commission have rejected requests to analyze disturbed land alternatives for projects being proposed for intact desert habitat, sometimes citing the difficulty companies have in acquiring private lands.  But hundreds of megawatts of solar energy development are proposed or being built on already-disturbed lands in private ownership -- typically on agricultural land -- severely undermining the assertion by the industry and its proponents that the destruction of public lands is necessary to generate solar energy.    In the latest news, SunPower is set to build a 579 megawatt facility in the Antelope Valley on nearly 7.4 square miles of agricultural land, financed by Warren Buffett

The Bureau of Land Management (BLM) last month issued the final environmental impact statement for Duke Energy's Searchlight Wind energy project, signaling initial approval for the company to industrialize nearly 29 square miles of Mojave Desert habitat near the small town of Searchlight, Nevada. Once the Department of Interior signs the record of decision -- expected early this year -- Duke Energy will transform this peaceful corner of the desert with 87 wind turbines (each standing taller than the Statue of Liberty) 35 miles of new gravel roads, and 16 miles of new transmission and collector lines, according to the BLM assessment. Construction will require over 9,000 trips by diesel trucks, and tons of cement and steel. Potential Impacts on Wildlife Are Extensive The area targeted by Duke Energy for the project is full of creosote bushes and Mojave yucca that can be hundreds of years old, and is surrounded by the Piute - El Dorado Critical Habitat Unit for the threatened d
