What is a fish without a river? What is a bird without a tree to nest in? What is an Endangered Species Act without any enforcement mechanism to ensure their habitat is protected? It is nothing.

We can't tell China what to do if we don't do it ourselves. You don't inspire someone to take an action by refusing to take it yourself. We are in a race to be the dominant clean-energy provider to the world. Maybe this goes without saying: We've got to get China into an international protocol and the magic words are "common responsibility with differentiated action."

We've introduced the New Apollo Energy Act, which is, I think, safe to say the most comprehensive and aggressive bill that has been introduced in Congress because it does have the scale, scope, and ambition of the original Apollo Project, and it attacks the problem in every way you can imagine. There's no silver bullet here, but there are lots of opportunities.

We’re the first generation to feel the impact of climate change and the last generation that can do something about it.'

We would never allow a utility to put their coal slag in a dump truck and back it up to the city park and dump it in unlimited amounts for free. But that is exactly what we do with carbon dioxide and methane.

We need to do for clean energy what Kennedy did for space in the original Apollo Project: Set a bold vision that will light the fires of innovation and make a game-changing shift in how we use and produce energy. And nothing less is adequate.
