What is the future of renewable energy under Donald Trump? Are recent gains made by solar and wind in jeopardy? Or is the momentum these industries have gained over the past eight years made them borderline unstoppable. This week on the Trump on Earth podcast we talk with a man who's literally writing the book on this topic. Varun Sivaram has been following following energy policy as the Phillip D. Reed fellow for Science and Technology at the Council on Foreign Relations. He is the author of the forthcoming book, Taming the Sun: Innovations to Harness Solar Energy and Save the Planet (MIT University Press, February 2018).
