The High-Carbon Truth Behind A ‘Green’ California Microgrid
The just-commissioned Calistoga hydrogen microgrid is a telling example of how public money can end up funding energy pathways that deliver little of what they promise. At first glance, the project appears well-intentioned. PG&E has positioned it as a resilience measure for a California community that faces wildfire-driven grid shutoffs. … [continued]

Beyond CATF’s Biased Analysis: Why Firm Power Isn’t The Full Answer
CATF recently published a report entitled Beyond LCOE: A Systems-Oriented Perspective for Evaluating Electricity Decarbonization Pathways advocating for a shift in how we evaluate energy technologies. At face value, their core criticism, that Levelized Cost of Electricity (LCOE) alone does not capture the full economic complexity of integrating intermittent renewable … [continued]

Renewables as a Bridge to Gas? America’s Energy Logic Goes Backwards
In recent remarks, John Ketchum, CEO of NextEra Energy, laid out a curious and somewhat baffling narrative: renewables should serve as a transition solution toward expanding natural gas generation. Yes, you read that correctly. After decades of framing gas as a so-called “bridge fuel” to a renewable future, the argument … [continued]
