The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition, we must lead it. We cannot cede to other nations the technology that will power new jobs and new industries, we must claim its promise. That's how we will maintain our economic vitality and our national treasure-our forests and waterways, our crop lands and snow-capped peaks. That is how we will preserve our planet, commanded to our care by God. That's what will lend meaning to the creed our fathers once declared.

I think one of the tragedies of the civil rights movement was because the civil rights movement became so court-focused, I think that there was a tendency to lose track of the political and community organizing, and activities on the ground, that are able to put together the actual coalitions of power throughout which you bring about redistributive change. And in some ways, we still suffer from that.

But you see, a rich country like America can perhaps afford to be stupid.

Our Founding Fathers, faced with perils we can scarcely imagine, drafted a charter to assure the rule of law and the rights of man, a charter expanded by the blood of generations. Those ideals still light the world, and we will not give them up for expedience's sake.

There is no shame in confusion or fear. "There was only shame in the silence fear had produced. . . . It was the silence that betrayed us."

Campaigning is different from governing.

A nation that can't control its energy sources can't control its future.
