We're going to bake this planet, and be a curse to all species, including our own, if we don't find an alternative to carbon-based fuel. That's the #1 problem.

If we stand for change, we can spark a popular movement with power, influence, magic and genius.

All the old rules - if you say some crazy stuff you get your show canceled or you get your campaign ended - don't apply in the world of social media. They don't apply in the world of reality TV.

People in red states and blue states can agree that if we can fight pollution and poverty at the same time, letting people work their way out of poverty without undermining community health, we have a moral obligation to do so.

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.

There's no higher honor, in my estimation, than being asked to serve in the White House.

We are trying to reinvigorate our stagnant energy sector, to create avenues for new wealth. Clean energy innovation, job creation and energy independence should be common ground for all Americans.
