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...

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...

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 updates...

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....

There are at least three ways to evaluate the economic viability of energy projects. The easiest way is to just repeat whatever is in a press release. The other extreme, a mandatory exercise for anyone poised to actually invest and build a project, is to develop complex projections that take into account the benefits of...

California’s state legislature may succeed in destroying its own oil industry, but it won’t change anything in the world. It will only export jobs and raise the cost-of-living here at home. Here’s a reality check. According to the Statistical Review of World Energy, in 2024, oil, natural gas, and coal contributed 87 percent of the world’s...

Earlier this year, the California Coastal Commission released a report titled “Statewide Strategy for the Coexistence of California Fishing Communities and Offshore Wind Energy.” In addition to providing a “guiding framework” to protect California’s fishing communities, it “presents a roadmap for proposed offshore wind projects to become consistent with California’s relevant Coastal Act policies that recognize...

Last month, for the uninitiated, we devoted a newsletter to the topic “Tips to Understand Our Convoluted Yet Obligatory Units of Water.” It attempted to summarize some essential facts and relevant units for anyone who wants to monitor state water policy. Now it’s time for those of us who fancy ourselves members of the energy...

Those of us following water politics and the water industry have become familiar with the most common units of water volume and water flow. Professionals in the industry make constant use of terms, often reduced to acronyms, forgetting that the rest of us may have no idea what they’re talking about. When it comes to...

The lightest and most abundant substance in the universe, the simplest possible molecule, hydrogen (H2), is touted as the clean burning fuel of the future. Zero pollution. But how can hydrogen be extracted or manufactured in its pure form, and how can hydrogen be stored, distributed, and converted into practical applications? If you’re following the...
