Dams Could Protect Ranchers From Climate Change’s Drought…But Could They Also Contribute To It?

It’s late May in Wyoming. It snowed last night, and more snow is predicted. That’s why it’s good that Big Piney Rancher Chad Espenscheid is behind the wheel of the truck. The roads are sloppy and Middle Piney Creek is running high. “Speaking of water,” he says, laughing. “Yeah, seems like it’s starting to flood,” I observe. “Yeah, it’s just wet.” That wetness is nerve-wracking for ranchers like Espenscheid. “It’s been a cold, long winter,” he says. “The cows and calves are really needing some sunshine about now. We got quite a bit of sickness going on around the valley.”

OPINION: Faulconer’s Welcome Housing Plan Also Helps With Climate Change

In the state Capitol, the response to California’s chronic housing shortage this year has been hugely disappointing. A bold proposal to make it easier to put up new apartment buildings and condos near mass transit and in single-family neighborhoods was abruptly killed last month by Sen. Anthony Portantino, D-La Cañada Flintridge, the chair of the Senate Appropriations Committee. State lawmakers continue to focus on subsidized “affordable housing” projects despite the years of evidence that this approach does little or nothing to bring down the high cost of housing in the Golden State.

OPINION: Climate Change Could Wipe Out L.A.’s June Gloom. Losing It Would Be Disastrous

For many of us in Southern California, the marine layer is a lifesaver. Those low decks of clouds — you might know them as June Gloom or May Gray — roll in off cool, ocean waters, shading coastal regions and cooling beaches and West Side cities even as the Inland Empire scorches. Now, we may be losing them. A new study by a Caltech climate scientist and two colleagues suggests those familiar low decks of stratus clouds could eventually become a casualty of the increasing CO2 emissions that are warming the planet.

 

Climate change: One Man’s Fight To Save A California Tree

As a child, he had happily played and hiked among these statuesque conifers, which provide shelter to black bears and black-tailed deer. By the age of 37, he wanted to do his bit to conserve and repair the land. But in the six years since he began, California has experienced severe drought, which scientists link to global warming, and 650 of Cody’s 750 seedlings died. Cody’s emotional account of surveying his dying trees struck a chord with thousands of people on social media when it was posted on Earth Day, in April.

Pumped Hydro 2 - SanV-WaterAuthority-May 2019

Water Authority Supports Bill to Spur Pumped Storage Projects

A bill that the San Diego County Water Authority’s Board of Directors voted to support in March is scheduled for a hearing Thursday in the state Senate Appropriations Committee. The proposed state legislation promotes the development of pumped hydroelectric storage projects to help meet state energy and climate goals.

Senate Bill 772 by Sen. Steven Bradford of Gardena promotes the development of pumped hydroelectric storage projects to help meet state energy and climate goals.

The Board’s support for the legislation followed the March release of a research paper from a team led by UC San Diego Professor David G. Victor that emphasizes the benefits of expanding pumped hydro energy storage as a cost-effective way to help California meet its renewable energy goals and reduce greenhouse gas emissions.

The Water Authority and the City of San Diego are exploring a potential pumped storage energy project at the San Vicente Reservoir that could store 4,000 megawatt-hours per day of energy, or 500 megawatts of capacity for eight hours.

Energy generated by renewable sources, like wind and solar, can be captured by energy storage facilities and then distributed then needed. Batteries and pumped energy storage will provide the needed energy storage for both short-term needs (batteries, less than 4 hours) and long-duration needs (pumped energy storage, 8 hours or more).

Large-scale, long-duration renewable energy source

A key to the San Vicente concept and others is development of statewide institutional and regulatory support for large-scale, long duration energy storage lasting up to eight hours. Pumped storage projects store solar and wind power during low-demand periods for use during high-demand periods, such as evenings when people are cooking, washing clothes and running air conditioners.

The State Energy Resources Conservation and Development Commission has identified bulk energy storage – including pumped hydroelectric storage – as a core strategy for integrating renewable energy resources into the California electrical grid and reducing greenhouse gases.

In addition, the white paper stresses the need for new state policies that will ensure that pumped energy storage projects enter commercial operations when they will be critically needed.

“To be consistent with California’s energy vision, active new policy support is needed to facilitate the development of pumped energy storage,” according to Victor’s paper. “Those policies should recognize the long lead times in building pumped energy storage projects (5 to 10 years). New policy efforts must begin now.

“Among the needed actions are state-backed support for some early projects that would jump start investment in this proven technology. This support can demonstrate viable business models and investment strategies that will pave the way for more private sector-led projects in the future.”

Providing ratepayer benefits

Pumped energy storage projects work like giant batteries by storing excess renewable energy during the day, when renewable power production peaks. Energy is released from the “battery” in the evening, when energy use increases, and renewable energy is not available.

Keeping the electrical grid reliable requires not only short-term energy storage, but long-duration, large-scale storage.

“Many expert studies have been performed that demonstrate the value of pumped energy storage, including CAISO’s Bulk Energy Storage Case Study, which found that a 500 megawatts (MW) pumped energy storage project in Southern California would provide ratepayers with a savings of up to $51M per year from improved efficiencies in system operation,” according to Victor’s white paper.

“Without significant new large-scale energy storage, California will likely be required to import more energy from other states, including potentially power generated with higher carbon emissions, such as coal,” the paper said. “The State will be unable to meet its renewable and climate goals reliably without large-scale energy storage.”

SB 772 is an attempt to address some of the issues identified by Victor and others. The legislation would require the California Independent System Operator, which runs the state’s power grid, to create a competitive bidding process by June 2022 to acquire a substantial quantity of long-duration energy storage – the type created by pumped hydroelectric storage.

OPINION: To Address Climate Threat, California Must Lead The Way On Green Bonds

We celebrated Earth Day last week, but climate change threatens our quality of life and poses material risk to our communities every day. A recent article by the Federal Reserve Bank of San Francisco points out that climate change also poses a real threat to our economy. Similarly, other reports identify tens of billions of dollars in infrastructure needs in California. They also say new infrastructure must be resilient, adaptable and responsive to the threat of climate change.

Western Bird Species Are Struggling In Face Of Rapidly Changing Climate

New research finds that climate change is putting stress on wetlands in the West’s Great Basin and that is putting pressure on bird populations navigating the Pacific Flyway. Changing water conditions linked to climate change are impacting the wetland habitats that waterbirds rely on. The basin includes most of Nevada and parts of Utah, Arizona, Oregon and the eastern edge of California. Warmer temperatures and less rain are affecting wetland habitats. “Eleven of those 14 birds that we looked at there were significant correlations between changes in climate and a decrease in population,” said Susan Haig, U.S. Geological Survey researcher emeritus.

Climate Change Is Already Hurting Fruit Breeders, And Consumers Could Soon Feel The Pain

In Mark Demuth’s research orchard in the shadow of the Blue Ridge Mountains, the peach tree twigs glow a soft red-brown under the strengthening late winter sun. The peaches are emerging from hibernation, he says, as he points out which of the stirring buds will open as leaves and which as blossoms come early April. Until then, the trees must undertake their most perilous journey of the year.

California Backs Imperial Beach Climate Change Lawsuit

A legal effort to get oil companies to pay for damage linked to climate change is getting a boost this week from California. Imperial Beach and Marin and San Mateo counties filed suit, hoping to force oil companies to pay for climate change impacts caused by their products. The municipalities argue the companies knew about the climate change their products would cause. The state is asking the court to keep the legal challenges in state court, where they stand a better chance of winning. More than a dozen suits around the country argue the energy firms spent years denying climate change impacts they knew would happen.

OPINION: Did Jerry Brown Do Enough On Climate Change?

Jerry Brown, in the last term of his two-part, 16-year governorship, came close to redeeming his environmental faults. Brown deserves a salute for striving to get out the message that climate change is indeed, in his words, a global “existential crisis” and that we are living in the “new abnormal.” He has been doing what a U.S. president ought to do, finding allies among nations, regions and cities for a crucial struggle — in contrast to President Trump , who abdicated the job.
