Recorded bird deaths at the Ivanpah Solar Electric Generating System ebbed only slightly in May after their peak in April, and more than half the bird carcasses reported to the state energy agency showed signs of injury from the plant's concentrated solar energy.
According to the Monthly Compliance Report for May filed with the California Energy Commission (CEC), a total of 80 birds were confirmed killed at the San Bernardino County solar plant in May. 44 of the birds showed clear signs of scorching, singeing, or melting of feathers consistent with exposure to extreme temperatures, as would happen if the birds flew through the plant's solar flux fields.
Solar flux burns weren't just recorded on the birds' sensitive feathers. Several of the carcasses were described as having had burns to the skin beneath the feathers. Two birds, both barn swallows, were described as showing injuries to their eyes consistent with solar flux injuries, and one of the two swallows had burns on his cloacal protuberance -- an organ roughly equivalent to the mammalian scrotum.
A 33-megawatt geothermal power plant approved in August by the Bureau of Land Management and U.S. Forest Service has the town of Mammoth Lakes worried about its drinking water supply.
Ormat Technologies' Casa Diablo IV Geothermal Energy Project would draw 29,000 acre-feet of extremely hot water per year from deep within the rock layers of the tectonically active region, using up to 16 newly drilled wells.
But that geothermally heated aquifer lies beneath the cold water aquifer from which Mammoth Lakes draws its drinking water, and locals are worried that the Ormat's pumping could draw down the cold water aquifer: a troubling prospect in this drought as locals become increasingly dependent on groundwater.
The California Energy Commission has turned down a request from the Sierra Club to become a formal legal party to proceedings regarding the proposed Palen Solar Electric Generating System west of Blythe in Riverside County.
The Sierra Club filed to "intervene" in the CEC's Palen proceedings on June 6. "Intervening" is a bit of jargon meaning to become a full legal party to the CEC's quasijudicial proceedings, whose testimony must be given full consideration in any decision. It's a step that gives more influence than members of the public have in the process; more like becoming a party to a lawsuit.
In its decision today denying the Sierra Club's petition, CEC pointed out that the official deadline for intervention in the case passed last September. Ordinarily, that'd be a slam dunk reason to deny the Club's petition. But the Palen case has gone through such a complex set of changes since that deadline, with new information being revealed, that granting the Club status as an intervenor would have been more than justified.
Over the last couple of weeks, ReWire's gotten a boatload of emails and social media forwards about the "Solar Freaking Roadways" Indiegogo campaign, in which inventors Julie and Scott Brusaw have raised well over $1.9 million to develop their modular solar-powered paving tiles. The Brusaws' goal is nothing less than replacing every bit of paved surface in the U.S. with the tiles, each of which will generate a maximum of 52 watts of electrical power when illuminated by the sun.
The Brusaws offer a vision of a nation that derives all its power from its roadways, which would include baked-in LEDs (to replace lane striping paint), heating elements to melt ice and snow, and integrated GPS. They claim that replacing our roadways with their panels will offer a source of solar energy enough to meet the United States' power needs three times over, with a roadway that's safer for pedestrians and animals.
As with any promise that sounds too good to be true, this one merits careful scrutiny -- especially since what the Brusaws are offering something a lot of us really want. Here are four reasons to take the Solar Roadways hype with a large amount of salt.
The U.S Environmental Protection Agency issued its long-awaited plan to reduce greenhouse gas emissions from power plants on Monday, but some climate activists are saying the move doesn't go far enough.
The EPA's proposed Clean Power Plan would, if approved, direct states to develop a range of programs to cut carbon dioxide emissions from power plants to 70 percent of 2005 emissions levels no later than 2030. Under the proposed rule, California would be asked to cut its power plant emissions by about 23 percent from 2012.
Though Monday's announcement was lauded by many in the environmental movement, the Clean Power Plan did not escape criticism from some who say the reductions goals are too little, and 2030 too late to forestall devastating climate change.
More solar was installed on residential rooftops than in big commercial settings during the first quarter of 2014, according to a trade report released Wednesday.
According to the Q1 2014 U.S. Solar Market Insight Report, released this week by GTM Research and the Solar Energy Industries Association (SEIA), the U.S. saw 232 megawatts' worth of residential rooftop solar installed from January through March of this year, while commercial installations, such as those atop big-box stores and warehouses, lagged slightly behind at 225 megawatts.
Utility-scale solar installations, a.k.a. those gigantic solar panel arrays out in the desert or on converted farmland, neatly outstripped both commercial and residential installations put together, at 873 megawatts installed in the first three months of the year.
The last time residential solar installations outstripped commercial projects was in 2002, according to SEIA, well before the current boom in solar started. The report's authors expect commercial installations to gain steam later in the year, but say the long-term trend likely favors household rooftop over commercial.
