We speak with author and activist Bill McKibben about the worsening climate crisis and why the world must rapidly transition to renewable energy in order to stave off the worst impacts. He says the Iran war has exposed the “utter folly” of fossil fuel dependence. “Sunlight has to travel 93 million miles to reach the Earth, but none of those miles go through the Strait of Hormuz,” says McKibben. “That makes it a very appealing alternative, especially now that it’s cheaper than burning coal and gas and oil.”

“…everyone around the world can suddenly see the utter folly of relying on a fuel that not only is destroying the planet’s climate, but also that can be bottled up behind a 20-mile-long waterway. Sunlight has to travel 93 million miles to reach the Earth, but none of those miles go through the Strait of Hormuz,” says [activist Bill] McKibben. “That makes it a very appealing alternative, especially now that it’s cheaper than burning coal and gas and oil.”
