Fossil Lobby Is Out of Arguments in 2025

TL;DR: Fossil narratives are collapsing. Economics, physics, and real-world deployment all now point one way: solar + storage. For several decades now, the fossil lobby has followed the renewable sector like a bad debt — constantly painting molehills as mountains, inventing false comparisons, and trying to derail public understanding any … [continued]

Why Molten Salt Won’t Be the Future of Industrial Heat Storage

Molten salt has long been positioned as the workhorse of high temperature thermal storage. Its story began with research in the 1980s and early deployment in Spanish parabolic trough plants in the 2000s. The technology was appealing on paper. A mixture of sodium and potassium nitrate has a high heat … [continued]

Ivanpah & Heliogen: Lessons from Concentrated Solar’s Decline

Ivanpah was supposed to be the future. When it opened in the Mojave Desert in 2014, with its three towers glowing like beacons and almost 400 MW of capacity, it was the largest concentrated solar power plant in the world. It had the backing of Google, NRG Energy, BrightSource, and … [continued]

Beyond the Hype: A Clear-Eyed Look at Geothermal’s Role in the Energy Transition

When I began writing about geothermal energy, I did not expect it to turn into a project that would span a dozen in depth articles, weeks of research, lengthy discussions with experts and eventually a full report. The original intent was modest. I wanted to understand where geothermal actually fits … [continued]
