I don't believe we're only motivated by our own self-interests. Often out of crisis comes this enormous wellspring of generosity and motivation.

I think that the world is in the middle of a huge transition that we have to make to renewable energy. We have to transition away from fossil fuels very, very quickly.

When the natural gas industry was knocking on my door, they were knocking on the door of millions of people. And that became something that Americans really needed to focus on.

The problem is that everywhere the gas drilling industry goes, a trail of water contamination, air pollution, health concerns and betrayal of basic American civic and community values follows.

It's the next phase of authorship of this country's energy future. It's gonna come from the people. It's not gonna be deus ex machina or Obama ex machina, or science ex machina. It's gonna be the people. It's not going to be a wind energy company that comes in and saves the day. It's going to be the people who figure this out.

Every single dollar spent lobbying a legislator on behalf of oil and gas is a toxic dollar that undermines public health and safety laws that protect Americans. That's contamination of the political system.

In a couple of decades you have half of the wells that are drilled right now, and you're talking about numbers in the millions of wells drilled, leaking. That's a huge crisis in terms of water contamination. There's no way to fix that problem.
