I think the most important thing is discovering an idea that moves you, and then letting people who are moved by that idea find each other, and work together. A lot of times people focus on the technical side-"oh, I've got to take a class on non-profit development." Too few people allow themselves to think outside the box with regard to their issue areas.

We need a national renewable energy goal. Such a goal, sometimes called a renewable energy standard (RES), would spell out what percentage of our power America plans to get from renewable sources.

The dirty energy crowd can be offset only by the power of the rising clean energy sector and the American people, aroused across party lines.

In America, we're in the middle of a cyberwar with Russia.

We need to aim high - in the area of 20-25 percent - to create the urgent demand for new technologies, manufacturing plants and green jobs.

The people who seem to us to be a very tiny elite, far off and mysterious, actually live in a fairly big world. The way they look at the planet is like they're looking at an index card covered in supply routes. We protestors had imagined ourselves this huge threat. But we were at best bemusing. To the extent that the people inside did care, it was almost like we were paying them a compliment-it reinforced their sense of power.

I used to go to all the environmental conferences when I wasn't an invited speaker. I was just somebody in the back taking a lot of notes. It was when I was least visible that I came up with the most cool stuff. Now, because I don't get to be Clark Kent, I feel like my learning curve is slowing way down. I'm always afraid the conversation will move on and I'll be up at the front of the room saying last year's speech.
