Since President Trump returned to office, his administration has been aggressive in rolling back clean energy initiatives. But that isn’t the whole story. Texas, California, and other states are bringing so much solar and battery power online that in March, fossil fuels generated less than half the electricity in the US for the first time ever. And internationally, solar has gotten so cheap to build and install that it’s fundamentally transforming many countries’ power grids. So where exactly does solar adoption stand in the US and across the world right now?

Climate activist Bill McKibben joins Host Ira Flatow to talk about the recent wins and future challenges that sun-powered energy faces, which he writes about in his new book Here Comes The Sun: A Last Chance for the Climate and a Fresh Chance for Civilization.

Guest: Bill McKibben is a climate activist and founder of Third Act. He’s based in Middlebury, Vermont.
