China’s Supercritical CO₂ Power Plant: A Big Step or a Dead End?

China has just added a supercritical carbon dioxide power generator to its energy mix, but will it stick around? The Chaotan One plant in Guizhou province aims to turn waste heat into electricity with impressive efficiency claims. But past performance suggests caution.Key TakeawaysThe new generator promises up to 30% better conversion of industrial waste heat than steam-based systems.This tech has been hailed as a breakthrough, but China's history shows it won't automatically mean widespread adoption.The real test is whether the plant can operate reliably over time and prove its worth economically.China’s approach to new technology often involves building first-of-a-kind systems just to see what works. It's a strategy that allows for learning, but also leads to many dead ends. This supercr...

Solar Dominates US Power Capacity Growth in Q3 2025

The Federal Energy Regulatory Commission's latest report shows solar energy leading the charge with over three-quarters of new power capacity additions through September 2025. Wind and other renewables follow, while natural gas struggles to keep up.Key TakeawaysSolar accounted for 75% of all US electrical generating capacity added in the first nine months of 2025.The mix of renewables is on track to exceed 40% of installed power generation within three years, with solar alone expected to reach 20%.Solar has been leading new capacity additions each month since September 2023.According to FERC's report, utility-scale solar installations reached a staggering total of 158.43 gigawatts by the end of September, marking significant growth from just under 92 GW at the start of 2023.In stark contra...
