Renewable energy also creates more jobs than other sources of energy - most of these will be created in the struggling manufacturing sector, which will pioneer the new energy future by investment that allows manufacturers to retool and adopt new technologies and methods.

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.

There's no silver bullet here, but there are lots of opportunities.

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.

With millions of family wage manufacturing jobs lost since 2001, we need an energy bill that takes bold action to tap into American ingenuity in order to lead the world in new clean energy technology, rather than playing catch-up to the Japanese, Danish, and Germans.
