I think we're in an era of unprecedented dominance by corporations. I think people understand that deeply; I don't think that's even questioned.

It is an incredibly hopeful experience watching communities come together and actually reassemble democracy. The democracy's been taken away from us. But they're reinventing democracy out there in rural Pennsylvania, in Philadelphia, in Pittsburgh.

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.

When your science runs into a policy roadblock, all of a sudden the science starts to disappear.

We're not living in a society that science actually dominates the conversation. We're living in a situation where some science is allowed and a lot of it's about policy.

There are regulations all over the spectrum that have to be done to the existing situation right now. But the only policy that makes sense is a nationwide moratorium: no new fracking, no new fracked wells.

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.
