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.

There's something really happening and really moving, and it's exciting and it makes me very optimistic because it is going to be the engine for how we really combat climate change. Which is strong communities.

We should be moving vigorously towards renewable energy. The technology of which is right here right now.

What we've got is the wholesale embrace of fracking domestically, internationally and for export. And this couldn't be further from what we really need to do to address climate change.

When you live in a watershed area, in a pristine area, and you could watch this whole place fall apart in front of your eyes, you don't sell your soul for a buck.

I have to have faith that we're going to succeed in transforming where we get our energy from. The big worry is whether or not we're going to do it before it's too late. And I think nobody knows the answer to that.

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.
