Good lord. Today was overwhelming. There were about 10 sessions, every one thought-provoking. I interviewed Jim Rogers, CEO of Duke Energy. I saw energy advisers from all three presidential campaigns offer substantive comparisons of the candidates’ climate positions. I saw in-depth discussions of carbon trading, green automobiles, shareholder resolutions, and the structure of cap-and-trade systems. I talked to journalists, people working on water and carbon trading, the guy who runs the X-Prize foundation, heads of NGOs, and representatives from Wal-Mart and Exxon. It’s friggin’ wonk heaven. I’m half-drunk and I’ve lost my voice from talking so much.

Over the next few days I’ll try to get up several more posts looking at some of the sessions and themes in detail. But I’ve got to be up in six hours to start all over again, so for now, I’m going to bed.
