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 need to do for clean energy what Kennedy did for space in the original Apollo Project: Set a bold vision that will light the fires of innovation and make a game-changing shift in how we use and produce energy. And nothing less is adequate.

Tolerance is the value that was selected to put on here, and tolerance is as American as apple pie.

Air is one we hold in common; it has a limited carrying capacity for pollutants and that's being used up by those who pollute the atmosphere. So we have to stop that externality. We would never allow a utility to put their coal slag in a dump truck and back it up to the city park and dump it in unlimited amounts for free. But that is exactly what we do with carbon dioxide and methane.

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.

We need to get our sons and daughters home and their responsibility for the security of Iraq needs to be assumed by Iraqis who will stand up and toe the line for their countries.
