The problem that we have in America now is, some people only see the positive stuff and wave off the toxic stuff, and some people only see the toxic stuff and wave off the positive stuff. You can't have an honest conversation.

Rather than continuing to base our economy on a finite supply of dead things, we can base it on sources that are practically infinite and eternal: the sun, the moon, and the Earth's inner fire.

We're just trying to end illegitimate government support for a single technology, which is un-American. We should be leading the world in the next generation of technological innovation. But we can't unleash private capital because of what the government is doing to stifle innovation and to choke competition.

To change our laws and culture, the green movement must attract and include the majority of all people, not just the majority of affluent people.

The problem that we have is that most Americans don't even study American history, let alone Pinochet, Mussolini, Hitler, Stalin and all these guys.

The government also has to get the public rules right. That means putting a price on carbon, so the cleaner forms of energy become more competitive. As soon as that happens, a tidal wave of new capital, innovation and entrepreneurship will flood into the clean energy space - creating new jobs and opportunities for Americans of all walks of life. We did that for the internet, with public investments in the basic system through the Pentagon, followed by rules that encouraged innovation and competition. And that is why the internet took off in the United States first.

America should be leading the world in green and clean solutions, and human rights. We shouldn't be leading the world in wars and incarceration rates and pollution. We can be a better country. I think we're going to be a better country.
