The rise of solar and hope for the future | Bill McKibben

In this episode of Climate Positive, Gil Jenkins speaks with Bill McKibben: author, educator, and one of the most acclaimed environmental voices of our time. His latest book, Here Comes the Sun, traces the rise of abundant, inexpensive solar power and argues that if we keep accelerating, we have a real chance not only to limit climate damage, but also to reorder the world on saner and more humane grounds. We dig into the data, the politics, and the people driving the global shift to solar, and Bill also opens up about the role of faith in his work and how he views the environmental movement’s trajectory today.

About Bill:

Bill McKibben is founder of Third Act, which organizes people over the age of 60 for action on climate and justice. His 1989 book The End of Nature is regarded as the first book for a general audience about climate change, and has appeared in 24 languages. He’s gone on to write 20 books, and his work appears regularly in periodicals from the New Yorker to Rolling Stone. He serves as the Schumann Distinguished Scholar in Environmental Studies at Middlebury College, as a fellow of the American Academy of Arts and Sciences, and he has won the Gandhi Peace Prize as well as honorary degrees from 20 colleges and universities. He was awarded the Right Livelihood Award, sometimes called the alternative Nobel, in the Swedish Parliament. Foreign Policy named him to its inaugural list of the world’s 100 most important global thinkers. McKibben helped found 350.org, the first global grassroots climate campaign, which has organized protests on every continent, including Antarctica, for climate action. He played a leading role in launching the opposition to big oil pipeline projects like Keystone XL, and the fossil fuel divestment campaign, which has become the biggest anti-corporate campaign in history, with endowments worth more than $40 trillion stepping back from oil, gas and coal. He stepped down as board chair of 350 in 2015, and left the board and stepped down from his volunteer role as senior adviser in 2020, accepting emeritus status. He lives in the mountains above Lake Champlain with his wife, the writer Sue Halpern, where he spends as much time as possible outdoors. In 2014, biologists credited his career by naming a new species of woodland gnat—Megophthalmidia mckibbeni–in his honor.

Book Blurb:

From the acclaimed environmentalist, a call to harness the power of the sun and rewrite our scientific, economic, and political future. Our climate, and our democracy, are melting down. But Bill McKibben, one of the first to sound the alarm about the climate crisis, insists the moment is also full of possibility. Energy from the sun and wind is suddenly the cheapest power on the planet and growing faster than any energy source in history—if we can keep accelerating the pace, we have a chance. Here Comes the Sun tells the story of the sudden spike in power from the sun and wind—and the desperate fight of the fossil fuel industry and their politicians to hold this new power at bay. From the everyday citizens who installed solar panels equal to a third of Pakistan’s electric grid in a year to the world’s sixth-largest economy—California—nearly halving its use of natural gas in the last two years, Bill McKibben traces the arrival of plentiful, inexpensive solar energy. And he shows how solar power is more than just a path out of the climate crisis: it is a chance to reorder the world on saner and more humane grounds. You can’t hoard solar energy or hold it in reserves—it’s available to all.

There’s no guarantee we can make this change in time, but there is a hope—in McKibben’s eyes, our best hope for a new civilization: one that looks up to the sun, every day, as the star that fuels our world.
