🔍 Episode Summary

Can the sun save civilization? In this episode of Saving the World from Bad Ideas, Mark Lynas sits down with legendary climate author and activist Bill McKibben to take on Bad Idea #22: "Solar can’t power the world."

McKibben, co-founder of 350.org and Third Act, makes a powerful case for solar as our best hope to avert climate catastrophe — and explains why a rapid, global energy transformation is not only possible, but already underway. They dive into the economics of solar, the moral urgency of ditching fossil fuels, the false promise of geoengineering, and why the shift to sun and wind can unlock a fairer, more democratic world. Bill’s new book Here Comes the Sun offers both realism and hope — and in this episode, he brings that rare combination to life.
