David Letterman Returns to TV for First Time Since Leaving ‘The Late Show’

Letterman rhapsodizes about the virtues of clean energy

David Letterman is charged up about solar energy in a new promotional video for the second season of Years of Living Dangerously, the Emmy-winning docu-series about the effects of climate change.

For Letterman’s episode — his first television project since retiring as host of The Late Show last year — he travels to India to explore how one of the world’s most populous countries intends to provide power to all its people.

The video features Letterman rhapsodizing about the virtues of clean energy while caressing an array of solar panels.

“I’ve created, excuse the expression, kind of a love affair with this,” he says serenely. “Think about the coal-fired, dangerous, smoke-belching generating plants, and then you look at this and it’s friendly. There’s something very appealing about this, and it’s smooth. Look at it: I can touch it and it’s safe. I put my head right there on it.”

Letterman even leans down and plants a kiss on one of the panels, with shocking results. (Watch the promo above.)

Season 2 of Years of Living Dangerously premieres Oct. 30 on National Geographic. Additional hosts include Arnold Schwarzenegger, America Ferrera, Cecily Strong, and Aasif Mandvi.
