Not wasting energy. It is the least sexy, but the single most important and always the least expensive. You would be very interested in a report by the McKinsey consulting firm that concluded that 40 percent of everything that we have to do to mitigate our emissions are net economic winners. They are cost effective and the most cost effective is not wasting energy. That's actually going to be the largest part of this whole journey, I believe - using less energy with the same beneficial results.

Things are difficult enough about Iraq without the Federal Government suppressing the truth about Iraq.

We allow it to be dumped into this community asset, which is our one and only atmosphere. So that has to change, and there's really only one entity that can do that. So we have proposed a cap-and-trade system to stop that unlimited pollution, to use the forces of the market to efficiently allocate scarce permits to allow CO2 into the atmosphere. That's just one of 500 things we need to do, but it's probably the granddaddy of them all.

When Arnold Schwarzenegger goes to his reward - how's that? That's a crack, but I treat Governor Schwarzenegger well in my book. He's done such great work in California; we'll forgive him one personal habit. Everybody should have one not-totally-CO2-friendly habit they can be forgiven for. So we'll forgive him that one.

I talk about reducing our dependence on foreign oil. If we're buying electricity from a solar-thermal plant in Tijuana, I'm not sure we should say that's evil. If we are buying wind power from Alberta, I don't have a huge objection to that.

We clearly need to break our addiction on Saudi Arabian oil that is a security threat to the United States.

I am going to leave everything on the field. I am going everywhere, and I am going to listen to everybody.
