An Eastern Sierra water agency will be filing suit over the approval of a geothermal power plant expansion, saying the project poses a threat to the local water supply.
The Mammoth Community Water District (MCWD), which provides water to Mammoth Lakes and nearby communities in Mono County, announced Friday that it will be suing the Great Basin Unified Air Pollution Control District for signing off on the 33-megawatt Casa Diablo IV geothermal plant east of town.
MCWD charges that the air district illegally approved Casa Diablo's state and federal Environmental Impact assessments despite what it calls a flawed analysis of the project's likely effect on Mammoth's potable groundwater.
Los Angeles has installed only two percent of the rooftop solar that's feasible in the city, and raising that figure to just ten percent would create 47,000 new jobs. That's according to a new report from UCLA's Luskin Center for the Environment and Environmental Defense Fund.
The Los Angeles Solar and Efficiency Report, or LASER, was released today as a response to the White House's Climate Data Initiative. It estimates that bringing L.A. up to ten percent of its rooftop solar potential would prevent about 2.5 million tons of greenhouse gas emissions each year.
That's like taking about 477,000 cars off the road, or burning around 2.4 billion fewer pounds of coal.
We reported earlier this week on a suggestion by state agency scientists that the concentrated solar energy at the Ivanpah Solar Electric Generating System might be killing birds without causing obvious visible burns to their feathers or skin. Now, a Federal wildlife investigations lab says there's no evidence to support that claim -- but it also says that might be because bird carcasses are rarely recovered from Ivanpah in good enough condition to study.
On Monday, our report said that California Energy Commission staff scientists Geoff Lesh and Brett Fooks had uncovered evidence that Ivanpah's concentrated "solar flux" could be killing birds that fly through the facility without causing significant external damage.
But when the commission's Chris Huntley checked with the U.S. Fish and Wildlife Service's forensics lab in Ashland, Oregon to see whether investigators there concurred with Lesh and Fooks, the response was essentially that carcass surveys at Ivanpah haven't given the lab the material they'd need to say yes or no.
The Los Angeles Department of Water and Power and a handful of solar contractors will celebrate the start of construction Wednesday on the Beacon Solar Project near the Kern County town of Cantil. The 250-megawatt project will be built on land adjacent to State Route 14 four miles south of Red Rock Canyon State Park.
LADWP bought the property in late 2012 from NextEra Energy, which had planned to build a solar facility there using parabolic trough mirrors, a technology that concentrates the sun's energy. Instead, LADWP will be using photovoltaic, or PV, panels on the site, which means the remote project in the western Mojave Desert marks another milestone in the last few years' dramatic shift in the solar industry from solar thermal to PV. Since 2007, the price of PV has dropped dramatically, making solar thermal increasingly uncompetitive.
The project will be built by SunEdison and Hecate Energy, which both agreed to build additional solar power stations within Los Angeles city limits. These urban solar projects will total 50 megawatts.
A desert protection group has formally asked the Federal Energy Regulatory Commission to reconsider its approval of a large pumped storage project near Joshua Tree National Park. In a formal legal request filed Monday, the Riverside County-based Desert Protection Society charges that FERC's approval of the controversial Eagle Crest pumped storage project violates several federal laws and should be reconsidered.
The group also says the project poses an undue threat to the Chuckwalla Valley's groundwater, as well as to wildlife including the Federally threatened desert tortoise.
The project, which FERC approved in June, would consist of two reservoirs holding about 21,000 acre-feet of locally pumped groundwater on the old Kaiser Eagle Mountain Mine property at the east end of Joshua Tree National Park. Environmental activists and the National Park Service have said the project would threaten the Park's desert tortoises by providing a gathering place for tortoise-eating ravens, and could permanently damage the Chuckwalla valley aquifer.
A solar power tower facility proposed for Riverside County would kill or injure more than twice as many birds with its concentrated solar radiation as compared to an existing solar project in San Bernardino County, according to a document published by the California Energy Commission on Friday.
The document, which contains testimony from commission staff submitted as part of upcoming hearings on the proposed Palen Solar Electric Generating System, estimates that the dangerous zone of concentrated solar "flux" around each of the project's two 750-foot power towers would be twice as large as those around the three towers at the Ivanpah Solar Electric Generating System near the Mojave National Preserve.
That would make each of the Palen towers almost four times as dangerous as their counterparts at Ivanpah, say commission staff, so that even with just two towers compared to Ivanpah's three, Palen would likely pose a 2.5 times greater risk to birds flying near the facility.
