Droughts Exposed California’s Thirst for Groundwater. Now, the State Hopes to Refill its Aquifers

/in , , /by /Science Magazine (American Association for the Advancement of Science) by Erik Stokstad

California’s Central Valley — one of the richest agricultural regions in the world — is sinking. During a recent intense drought, from 2012 to 2016, parts of the valley sank as much as 60 centimeters per year. “It isn’t like an earthquake; it doesn’t happen, boom,” says Claudia Faunt, a hydrologist with the U.S. Geological Survey. But it is evidence of a slow-motion disaster, the result of the region’s insatiable thirst for groundwater.

Study: Warming Makes US West Megadrought Worst in Modern Age

/in , , /by /AP Newsby Seth Borenstein

A two-decade-long dry spell that has parched much of the western United States is turning into one of the deepest megadroughts in the region in more than 1,200 years, a new study found.

And about half of this historic drought can be blamed on man-made global warming, according to a study in Thursday’s journal Science.

Scientists looked at a nine-state area from Oregon and Wyoming down through California and New Mexico, plus a sliver of southwestern Montana and parts of northern Mexico. They used thousands of tree rings to compare a drought that started in 2000 and is still going — despite a wet 2019 — to four past megadroughts since the year 800.

106,000 American Clean Energy Jobs Were Lost in March

/in , /by /pv magazineby Tim Sylvia

The dramatic impacts of the Covid-19 pandemic have hit every sector of the U.S. economy hard, with renewable energy being no exception. Today, BW Research released an analysis of unemployment data that shows more than 106,000 clean energy workers lost their jobs in the month of March.

Those 106,000 job losses represent a 3% loss in employment across the clean energy industry. In 2019, the clean energy industry added more than 70,000 jobs for a 2.2% growth rate, one which outpaced the U.S. workforce as a whole. The renewable energy generation sector alone lost 16,500 jobs.

The analysis, coupled with forecasts from industry trade groups and companies, led BW Research to the conclusion that, if no actions are taken quickly to support the industry, up to 500,000 jobs could be lost — or almost 15% of the clean energy workforce.

Broken down by state, California experienced the largest number of layoffs, losing 19,900 jobs, which equates to more than 3.5% of its clean energy workforce.

Wet Spring a Boon to Water Supply, Native Plants

/in , , /by /The San Diego Union-Tribuneby Robert Krier Quoted: San Diego County Water Authority

In San Diego County and across California, it’s been an awesome April for precipitation.

The Sierra snow pack, although still much smaller than normal for this point in spring, has partially made up what had been a huge shortfall just a few weeks ago. And just about every place from the desert to the coast has benefited from a substantial soaking.

Last week’s record-breaking storm lifted San Diego County well above normal precipitation for the rainfall season. The city of San Diego has had its wettest spring in decades, and it has already recorded 3 more inches of rain since Oct. 1 than it normally gets in an entire year.

Opinion: Collaboration is the Answer to California’s Fishery and Water Supply Challenges

/in , , /by /CalMattersby Roger Cornwell

California has the opportunity to enter a new era in water management. Unprecedented efforts by leaders at the state and national level have led to the kind of cooperation that will provide valuable benefits to water users and the environment.

I know because that’s what we’ve been doing in the Sacramento Valley for many years. The kinds of success we’ve achieved can be replicated in other parts of the state. By working together, we can accomplish much more than can ever be achieved when competing interests are fighting.

California’s current water regulatory system is completely broken. Farms, towns and cities suffer continued cutbacks and threatened fish species continue to dwindle. The only recourse currently available seems to be an ongoing parade of lawsuits that further paralyze the system and help no one.

Early April Precipitation is Expected to be Below Normal Where it is Most Needed in Northern California

/in , , /by /Los Angeles Timesby Paul Duginski

April showers may be more scarce than normal north of Point Conception in California, according to an outlook produced by the National Oceanic and Atmospheric Administration.

This area where the probability of precipitation is below normal includes virtually all of Northern California and the crucial northern Sierra Nevada, where the state’s largest reservoirs are located.

While snow cover has increased thanks to a series of March storms, the Northern Sierra 8-Station Index stands at 56% of normal for the season. As of March 24, another 29.25 inches would be needed to reach the season normal of 54.52 inches.

California Pilot Plant Could be Churning out ‘Sustainable’ Lithium as Early as 2023

/in , /by /Energy Storage Newsby Andy Colthorpe

Following recent reports that newly accessed geothermal power resources in California could also provide access to lithium as a valuable by-product, a pilot facility is now in development.

Resource developer Controlled Thermal Resources recently signed a power purchase agreement for 40MW of geothermal energy with Imperial Irrigation District, a water – and energy – provider in Southern California.

CTR is also now creating Hell’s Kitchen Co, facilities for lithium extraction and chemical processing at its geothermal plant at Imperial Valley’s shallow, saline Salton Sea. CTR has now partnered with technology provider Lilac Solutions, which has its own proprietary ion exchange technology, to open up a pilot plant to extract lithium from the run-off geothermal brine

California Mountains Blanketed in Snow After March Storms

/in , , /by /Associated Press (Sacramento Bee)by John Antczak

California mountains are blanketed in snow and much of the state has had plenty of rain in a remarkable March turnabout from the extremely dry first two months of the year.

The most recent statewide storm started during the weekend and, despite diminishing, snow snowfall and showers were still occurring here and there.

In the Sierra Nevada, Homewood Mountain Resort on the west shore of Lake Tahoe reported late Tuesday a storm total of 114 inches (289.5 centimeters) of snow at its summit and 74 inches (188 centimeters) at the base.

Lithium Startup Backed by Bill Gates Seeks a Breakthrough at the Salton Sea

/in , , /by /Los Angeles Timesby Sammy Roth

David Snydacker knew going in that California’s Imperial Valley was a “graveyard for lithium-extraction technologies.”

For years, companies had tried and failed to find a cost-effective way to pull the valuable mineral — a key ingredient in the batteries that power electric cars — from the naturally heated fluid deep beneath the Salton Sea. One of the most recent busts was Simbol Materials, a much-hyped startup that collapsed in 2015 shortly after Elon Musk’s Tesla Inc. offered to buy the firm for $325 million.
