Farmland Owners Look to Solar As Groundwater Restrictions Loom

New solar energy installations may be headed to the valley portion of Kern County as investors, government officials and advocacy groups weigh options for reusing land that will have to be taken out of production as a result of state restrictions on groundwater pumping.

Photovoltaic solar arrays, for years an attractive investment for local farmland owners, would appear to align with California’s ambitious goal of meeting all its electricity needs with renewable energy.

Renewable Energy’s Booming, But Still Falling Far Short of Climate Goals

Renewable energy capacity quadrupled worldwide over the past 10 years, with an estimated $2.6 trillion invested in its growth, a new report from the United Nations Environment Programme shows. But the speed of that growth still falls far short of what researchers say is needed to keep global warming in check.

California’s Clean Energy Conundrum

San Diego – While California draws nearly one third of its power from renewables, solar and wind energy systems are periodically pulled offline because there’s not enough demand when the wind is blowing and the sun is shining. These so-called “curtailments” increased significantly between 2014 (when they were almost non-existent) and today. They could soon become a major barrier to a more sustainable future as more and more renewable energy sources are developed to meet peak demands.

Thankfully, California water agencies are well-positioned to play a pivotal role with a solution that makes the state’s electrical grid more flexible, stable and efficient. Strategic deployment of large-scale, long-duration pumped storage facilities could minimize curtailments and provide many other benefits. That would help California achieve its aggressive targets to supply at least 60 percent of the state’s energy from renewables by 2030 and 100 percent from clean energy sources by 2045.

Rep. Scott Peters Pledges Town Hall On Climate Crisis Following Activist Pressure To Support Green New Deal

Rep. Scott Peters of San Diego has agreed to hold a town hall meeting on climate issues following months of pressure by local activists on him and other members of Congress to support the Green New Deal. Peters’ announcement comes after Rep. Susan Davis, D-San Diego, cosponsored the hotly debated resolution in June, which calls on the federal government to zero out greenhouse emissions by 2030 and create jobs in renewable energy and other sectors. After initially brushing off calls to support the Green New Deal, the congresswoman surprised constituents and local climate groups when she announced her support for the resolution during a town hall-style event last month.

Power Plants Create Giant Water Battery

California is a leader in renewable energy, and the state has pledged to use only clean sources for electricity, including wind and solar power, by 2045. One hurdle is energy storage, but an old solution involving water may help the state reach its goal of zero emissions. The solution is “pumped storage,” which uses water in reservoirs at different elevations to smooth the fluctuations of intermittent power from the wind and sun, and makes electricity available when it is needed. California has mandated 60% renewable energy sources for its power generation by 2030, and all zero-emission sources by 2045, which could include nuclear generation along with renewables.

San Diego County Quality of Life Indicators Mostly Positive in 2018

A report released today showed improvement in 2018 for the majority of 15 indicators used to measure San Diego County’s quality of life. The Equinox Project Quality of Life Dashboard measures and benchmarks several environmental and economic trends throughout the region.

The analysis highlighted the San Diego County Water Authority for developing water solutions for San Diego and the Southwest using a “portfolio approach.” One of the initiatives under that approach includes efforts to store water in Lake Mead on the Colorado River, which would benefit both San Diego County residents and many other river users.

The nonpartisan Equinox Project report is a source of public policy research and analysis to guide policymakers, planners and other officials, said Emily Young, executive director of The Nonprofit Institute at the University of San Diego, where the project is based.

Water use increased in 2018

“There’s no one indicator when you’re talking our quality of life in the San Diego region,” Young said. “And in fact, the whole point is all of these things are connected. If you’re talking about air quality, you really can’t talk about that if you’re not also talking about our transportation systems and the pollution generated from them.

“Whether we’re looking at an issue like water, which is very precious to the San Diego region, or other issues around transportation or housing, all of these are things that we’re measuring our progress on,” said Young.

Per capita water use in San Diego County

*This data includes agricultural water use served by local water agencies.
In 2018, National City had the lowest municipal and industrial (M&I) water use at 78 gallons per capita daily. Yuima’s high per capita M&I potable water use occurs because a large amount of water used for horticultural irrigation is classified as M&I, and the district services a small population (less than 2,000 people).

Measuring quality of life

Six of the 15 indicators received a “thumbs-up” in the report, including air quality, electricity use and renewable energy. Four indicators, including water use, received a “thumbs-down.”

“Daily residential water consumption in San Diego County increased by 8.3% from 84 gallons per capita in 2017 to 91 gallons in 2018,” according to the report. “Water use has increased since the statewide water restrictions were lifted in 2017, though below pre-drought levels.”

Water use lower in 2019

Despite the slight increase in water use during 2018, residents continue to conserve compared to previous years.

“While extreme dry conditions contributed to increased residential water use in 2018, per capita water use was still lower than historical, pre-drought levels,” said Alexi Schnell, water resources specialist with the Water Authority. “Water use to date in 2019, a much wetter year, has been consistently lower than in 2018.

“There will always be fluctuations based on weather and other factors, but the San Diego region continues to embrace water-use efficiency, and per capita water use in the region is not forecasted to return to pre-drought levels for the foreseeable future,” Schnell added.

The report noted that “the San Diego region is making significant commitments to water efficiency and recycling” and has diversified local supply with the Claude “Bud” Lewis Desalination Plant in Carlsbad, the nation’s largest seawater desalination plant.

California ALJ Proposes Statewide Renewable Energy Procurement For Utilities

A California Administrative Law Judge (ALJ) on Monday proposed statewide procurement for renewable resources, finding that proposed resource plans from utilities and other power providers will not reduce greenhouse gases enough to meet state goals. The proposed decision from ALJ Julie Fitch would refuse to adopt the combined integrated resource plan (IRP) from the state’s utilities and community choice aggregators (CCA) because it “does not meet the GHG emissions goals” and could challenge reliability. Instead, Fitch proposed a new statewide Preferred System Portfolio that would guide generation decisions out to 2030.
