The Solar Decathlon is being held in California at long last.  The competition was first held in 2002, and features homes powered by rooftop solar panels, and built by teams from across the country and overseas competing to be the most sustainable in various categories.  The overall winning team must design and build a home that meets the following general criteria: Is affordable, attractive, and easy to live in Maintains comfortable and healthy indoor environmental conditions Supplies energy to household appliances for cooking, cleaning, and entertainment Provides adequate hot water Produces as much or more energy than it consumes. Consider the "DesertSol" entry designed and built by the University of Nevada, Las Vegas (UNLV).  The DeserSol house uses a solar thermal system to heat water and the home itself, photovoltaic panels to supply energy, and advanced engineering that reduces framing materials by nearly 20%.  The entry will be on display at the Las

Tbe Bureau of Land Management (BLM) in September released the final environmental impact statement (EIS) for the Silver State South solar project, which would destroy approximately 3.7 square miles of intact desert habitat. Although the direct impact on wildlife may not compare to BrightSource Energy’s Ivanpah Solar project, the Silver State South project almost certainly will have significant long-term effects on the ability of the desert tortoise to maintain habitat connectivity. The BLM’s preferred alternative supports the solar project, and secondarily designates an Area of Critical Environmental Concern (ACEC) to protect the desert tortoise habitat that First Solar does not want to destroy.  The ACEC is a welcomed sweetener, but still does not override the bitterness that arises from the fact that destruction of habitat for the solar project is completely unnecessary since the solar panels would be just as happy on already-disturbed lands somewhere else in the state.  Tort

First Solar, the company destroying several square miles of desert habitat to build solar facilities on pristine desert wildlands,  sided with utilities companies seeking to limit the expansion of rooftop solar in a regulatory filing this month.  First Solar's move is not surprising because the panels it manufactures and uses at its large solar facilities are not very efficient, and typically are not used in rooftop solar installations.  The company depends on monopolistic utility companies to buy energy from its projects, funds anti-environment politicians , and has insisted on building a large project that biologists have warned will degrade habitat connectivity for the threatened desert tortoise.

Southern California Edison (SCE) is planning to invest upwards of one billion dollars in new transmission lines through Lucerne Valley, connecting substations in the Barstow area to Hesperia.  Never mind that the utility already has three existing major transmission pathways through the region, in addition to lines owned by Los Angeles Department of Water and Power (LADWP).  SCE argues in its application to the California Public Utilities Commission (CPUC) that the "Coolwater-Lugo" transmission upgrade is needed to alleviate a bottleneck on the lines running from Kramer Junction to Hesperia, and to provide interconnection for up to 1,000 megawatts of renewable energy development. Although some of the new line would run along an existing transmission corridor, the utility would add nearly 15 miles of lines along a new corridor following Barstow Road before veering northwest to join another LADWP corridor, further entangling otherwise scenic desert with industrial-scale devel

The California Energy Commission (CEC) this month published part of its Final Staff Assessment for BrightSource Energy's Palen Solar power project.  After evidentiary hearings this fall, the CEC plans to decide whether to approve the project proposed for the Chuckwalla Valley between Indio and Blythe, resulting in the destruction of up to 5.9 square miles of desert habitat that currently hosts kit foxes, Mojave fringe-toed lizards, and burrowing owls.  Biologists are concerned that the project would not only disrupt sand transport through the valley that sustains fringe-toed lizard habitat, but also pose a collision and burn risk to a variety of birds, from golden eagles to the endangered Yuma clapper rail.

California's legislature is considering a bill ( A.B. 327 ) that may solidify the monopoly status of investor-owned utility companies by charging all ratepayers a fixed fee.  Not only would this unfairly penalize ratepayers who invest their own money to make their homes and businesses energy efficient, it would strangle nascent efforts to democratize our energy grid with rooftop solar.  California ratepayers are already being taken to the bank by utility companies; each utility collects a guaranteed return of over 10% from ratepayers.  No matter what they build or destroy, they can earn a profit.  Even when utility companies make bad decisions, they expect to be compensated and rewarded.  For example, now that Southern California Edison shut down its failed nuclear plant at San Onofre, it wants to collect 2.4 billion dollars from ratepayers, enough money to pay for its misguided investment and earn at least 5.5% extra.  Apparently utility companies don't want to give up

If you want to have your voice heard regarding the Desert Renewable Energy Conservation Plan (DRECP) - a Federal and state effort to figure out the appropriate locations for large-scale renewable energy development in California's desert - you will have your chance on Friday, September 6, and Saturday, September 7.   As noted in the Desert Sun , the meetings will afford the public a chance to provide input to the planners.  The plan will identify areas for conservation, and areas for renewable energy development.  Speak up in favor of expanded conservation protection for our desert wildlands, and for renewable energy on rooftops and already-disturbed lands.  There is no need to for industry to destroy more wild places when we have a more sustainable alternative. Meeting details: Lucerne When: 6:30-9:30 p.m. Friday Where: Lucerne Valley Elementary School, 10788 Barstow Road Yucca Valley When: 9 a.m.-1 p.m. Saturday Where: Yucca Valley Community Center, 57090 29 Palms High

I've written recently about the desert's visual resources . The term itself - visual resources - seems so inadequate; as if you could actually quantify the serenity and beauty of a desert landscape.  The Mojave Desert has a soundtrack that is equally difficult to capture.  When I'm not in the desert, I can at least enjoy the photos I took of the landscapes, but my cheap camera microphone is never going to pick up all of the beautiful sounds.   I have tried using the video function on my camera to record the sound of the coyotes in the distance, but I'm left with a couple of faint yips drowned out by the breeze hitting the microphone. Luckily a pair of naturalists, Sarah Koschak and Andrew Skeoch, travel the world recording the sounds of nature, and compiled sounds from the Mojave Desert in an album available on their website.   Sarah wrote about realizing her wish to camp amongst Joshua trees under a starry sky, and listening to the yip of the coyotes.  Near the
