2nd Tribal Solar Plant Approved On Nevada Reservation

With ground only newly broken on a 250 megawatt solar project that will cover about 2,000 acres of the Moapa Paiute Reservation north of Las Vegas, the Interior Department today announced its approval of a second solar project on the tribe's lands.

The Moapa Solar Energy Center Project will be built on about 850 acres of the reservation in the shadow of the soon-to-be-shuttered Reid Gardner coal-fired power plant, and will generate a maximum of 200 megawatts of power.

"Today's announcement reflects the Obama Administration's steadfast commitment to work with Indian Country leaders to promote strong, prosperous and resilient tribal economies and communities," said U.S. Secretary of the Interior Sally Jewell, in announcing Interior's decision approving the project. "This solar project and these grants also deliver on the President's Climate Action Plan goals to spur important investments and jobs in tribal communities."

Natural Gas May Be a Lot Worse for Climate Than Suspected

Natural gas and oil fields may well be releasing far more climate-killing methane into the atmosphere than previously thought, undermining natural gas' usefulness as an alternative "bridge fuel" for society to use to wean itself off coal in fighting climate change.

That's according to a new federally funded study to be published in the Journal of Geophysical Research: Atmospheres. In the study, conducted by researchers from NOAA's Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder (CIRES), oil and gas fields in Weld County, Colorado were revealed to be leaking three times as much methane as expected into the atmosphere. Methane, a primary constituent of natural gas, is a greenhouse gas 34 times more potent as carbon dioxide.

The researchers also found seven times as much atmospheric benzene coming off the wells as had been expected, and about twice the expected levels of a set of volatile organic compounds that contribute to ozone formation. Benzene is a known human carcinogen.

Fact Check: How Much Water Does Solar Power Really Use?

There's an infographic going around lately that claims to show the relative amounts of water used by four different sources of electrical power: coal, nuclear, natural gas and solar. The graphic claims that solar comes out the clear winner in terms of water conservation, using no water at all to generate power. But is the claim correct? Not quite.

The graphic, produced by the "Climate Reality Project," is making the rounds of social media. It's pretty straightforward, at first glance. Coal-fired power plants use up 1,100 gallons of water for each megawatt-hour of power produced. (A megawatt-hour is about what a typical California household would consume in six or seven weeks.) Nuclear and natural-gas-fired power plants use water 800 and 300 gallons for the same amount of power, respectively. And solar, according to the Climate Reality Project, is the least water-wasteful of all four sources of energy, at zero gallons of water per megawatt-hour.

On Facebook, the graphic's creators share the news breathlessly, saying "Whoa - you probably know that solar power plants produce electricity without producing carbon pollution, but did you all realize they also save so much water? 'Share' to let your friends know, too!" But is the graphic accurate? That depends what you mean by "accurate."

Opposition Grows To Proposed Solar Tower Project

When last ReWire checked in on the proposed Palen solar project, its builders were asking the California Energy Commission to restart hearings on the project that had been suspended in January. That was in March; now, it's becoming clear that there's significant opposition to putting the project back on the table -- including from the CEC's own staff.

The Palen Solar Electric Generating System (SEGS), to be built by BrightSource Energy and Abengoa Solar (doing business as Palen Solar Holdings, or PSH) on four square miles of desert just off Interstate 10 in Riverside County, would generate a maximum of 500 megawatts by using tens of thousands of mirrors to focus sunlight on boilers atop two 750-foot solar towers. That much concentrated "solar flux" is proving to have nasty effects on wildlife at BrightSource's significantly smaller Ivanpah project.

Solar flux damage to wildlife was the main reason that the CEC proposed to reject Palen SEGS' design, just before PSH asked the Commission to suspend hearings on the project in January. Now, the builders say they've collected data that says their design poses no more risk to birds than alternatives suggested by CEC. But opponents aren't convinced -- including Audubon California.

Another Huge Solar Plant Goes Online in California's Desert

With a flick of a giant ceremonial switch but not much else in the way of fanfare, the Genesis Solar Energy Project has gone online in the eastern desert of Riverside County. The 4,600-acre project near Ford Dry Lake will generate up to 250 megawatts of power to be bought by the Northern California utility Pacific Gas & Electric (PG&E).

Approved by the California Energy Commission and the Department of the Interior in 2010, the project, built by NextEra Energy Resources 25 miles west of Blythe, hit speedbumps ranging from lawsuits to wildlife illnesses to unanticipated archaeological discoveries on the path to Thursday's figurative ribbon-cutting.

Among the dignitaries flipping the "switch" on April 24 at Genesis were CEC Commissioner David Hochschild and Michael Peavey of the California Public Utilities Commission. The event formally adds up to 250 megawatts to California's solar thermal generating capacity.

Giant Kern County Solar Project Officially Dead

The California Energy Commission just dealt the final death blow to a proposed solar project that was once one of the most controversial in the California Desert. With no one making any moves to object, the CEC terminated the application process for the Ridgecrest Solar Power Project, which would have generated 250 megawatts on almost 4,000 acres of public lands in the western Mojave.

Tuesday's move by the CEC will surprise no one: the project has been effectively dead for some years. The proponent, Solar Millennium, filed for bankruptcy in 2012 and was liquidated by 2013. The Bureau of Land Management revoked the project's right to use public lands even earlier, in 2011, a year after the CEC staff recommended against approving the project because of the damage it would do to the desert's wildlife.

But today's action does close a chapter in the early history of utility-scale desert solar projects, and it's worth remarking upon as the end of an era -- and as good news for one of the Mojave's rarest mammals.
