1564: Practical Roadmap to 100 Percent Clean Energy Worldwide with Mark Z. Jacobson

Saturday, April 11, 2026

From smoggy San Diego tennis courts to shaping the Green New Deal, my guest Mark Z. Jacobson has spent his life answering one question: How do we actually fix air pollution and climate change? In this episode, I talk with the Stanford professor and director of the Atmosphere/Energy Program about why we don’t need miracle technologies we just need to deploy the clean solutions that already work. You’ll hear why many “solutions” like carbon capture, blue hydrogen, biofuels, and new nuclear are expensive distractions, how wind, water, and solar can reliably power the grid 100%, and why electrifying everything (cars, heating, cooking, industry) slashes both energy use and deaths from air pollution.

Mark also walks me through real-world data from 150+ country-level transition plans, his own 100% renewable home, and why the biggest barrier now isn’t technology it’s politics, misinformation, and lack of focus. If you’re a founder, policymaker, or just a concerned citizen wondering whether we’re doomed or if the solutions are real, this episode will help you see what actually works, what doesn’t, and how you and I can both help accelerate the transition.

Quotes:

“We don’t need miracle technologies to solve climate change we need the courage to deploy the solutions we already have.”

“Every year we delay the transition to clean energy, seven and a half million more people die from air pollution. Waiting is not neutral it’s deadly.”

“This isn’t a technology problem anymore; it’s a focus problem. When we ignore the distractions and double down on wind, water, and solar, a 100% clean energy world becomes inevitable.”
