A look back at the biggest clean energy developments of 2025 — and we reveal why electric trucking in China may be the most important story of the year. We break down record global growth in solar, wind, and EV adoption, explain how renewables are now outpacing fossil fuels in new investment, and explore why China's rising clean power generation is finally pushing its CO₂ emissions lower even as electricity demand grows CES 293 - Google Docs.

(Letters are being held over until our next bonus episode.)

The show also checks in on Norway, the world's EV laboratory, where electric vehicles now dominate both new sales and the overall vehicle fleet. The hosts discuss what Norway's data tells us about the future of gas, diesel, hybrids, and plug-in hybrids — and what it means for automakers still betting on combustion engines. Other highlights include a major San Francisco power outage, Volkswagen shelving the ID. Buzz in the U.S., and encouraging new data suggesting the world may have passed peak air pollution.
