There are some cities that are doing good stuff, but there aren't enough of them. If you don't fight for what you want, then you deserve what you get. And in politics, if you don't ask, you don't get at all.

There are about 46,000 jobs supported by the solar industry right now. That's fewer than it should be, too. And you have a whole other set of jobs in energy-efficiency in buildings and in creating the "Smart Grid," as we call it.

By kicking its carbon addiction, America will increase its national wealth and generate millions of jobs that can't be outsourced.

On the eve of historic fights for health care and clean energy, opponents of reform have mounted a vicious smear campaign against me. They are using lies and distortions to distract and divide. I have been inundated with calls - from across the political spectrum -- urging me to 'stay and fight.' But I came here to fight for others, not for myself. I cannot in good conscience ask my colleagues to expend precious time and energy defending or explaining my past. We need all hands on deck, fighting for the future.

The usual pattern of demagogues is to promise the moon, fail to deliver, and then blame vulnerable others for those failures.

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.

The question is: do we pay a little bit more now? Or do we pay a whole lot later? For the equivalent of a postage stamp a day for each American, we can put a price on carbon today that will send a signal to private capital to invest in the clean technologies of tomorrow. Taking a vast portfolio of new energy solutions to scale will ultimately drive down costs through competition.
