#160 – The Energy and Water Footprint of AI

Whether artificial intelligence should be regulated, and if so, how, has almost overnight become one of the biggest political issues of our time.  And with AI comes a surge in construction of massive data centers, for which we should minimize impact on the surrounding communities. But to the question of how we will find enough […]

#159 – Comments on the “Water Quality Control Plan” for the Delta

The August 2026 final draft of the State Water Resources Control Board’s (SWRCB) “Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Watershed” has been released. Written comments will be accepted through September 18, and the board will also take oral comments at the October 28-29, 2026 meeting where the SWRCB may formally adopt the plan. […]

#158 – Where Does California Get its Energy?

Finding quality, consolidated information on energy use in California is surprisingly difficult. The California Department of Energy provides detailed information on electricity production, and a variety of reports on, for example, refinery inputs and production. But there is no report available from official state sources that puts it all together. This is unfortunate, because as a state […]

#156 – Iron Air Batteries – Niche, or Next Big Thing?

Iron air batteries appear poised to play, at the least, an important niche role in the emerging electric age. A very recent example of this is the $750 million equity financing that Form Energy secured this week, raising the total investment in that iron air battery manufacturer to over $2 billion. Iron air batteries offer long-duration electricity storage […]

#155 – Is Covering California’s Aqueducts and Canals with Solar Panels Economical?

Earlier this week, a respected YouTube channel covering the future of technology and energy released a video exploring the viability of solar panels covering California’s canals and aqueducts. The videos are hosted by Ricky Roy, a California-based mechanical engineer whose channel is called “Two Bit Da Vinci.” Reviewing his findings is an opportunity to offer some […]

#154 – Debunking the Allegedly Prohibitive Cost of Desalination

Earlier this summer a guest op-ed appeared in the Orange County Register, “Learning the right lesson from San Diego’s desal water surplus.” But the “lesson” presented was only partly accurate. What the authors, both affiliated with the Property and Environment Research Center (PERC), got right was the need to change regulations that restrict the ability for farmers to […]

#153 – A Fact-Based Appraisal of California’s “Net Zero” Strategy

The Statistical Review of World Energy is arguably the most authoritative and comprehensive source publicly available for national and global energy statistics. And a funny thing happened between the report issued in 2024 and the report issued in 2025. “Renewables” as a percent of total energy consumed in 2023 was quietly lowered from 9.3 in the U.S. […]

#152 – Dredging the Delta Can Prevent a Catastrophe

It’s January 2027, and for the last few months, a super El Nino has already delivered torrential rains to the Pacific Coast of North America. California’s reservoirs have been releasing record quantities of water to preserve space for the next round of precipitation but their remaining capacity to absorb runoff is dangerously low. From the peaks […]

#151 – Commercializing Hydrocarbon Production from Air and Water

Whenever evaluating a new energy technology, caution is warranted. During what was arguably the first big cleantech boom around 2009, schemes were sold to angel investors thrilled to find a hot sector in the wake of the recent financial crash. Almost anything that sounded good got funded. Some of these schemes, such as a “clean” […]
