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.

I reflect back 35 years ago, and look how far we have come in America with our environmental policy to improve the conditions of our air and water, and we have had some real successes.

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.

There is no excuse for this administration shielding information about Iraq and the fact that we have great difficulties there from the American people.

We have had a loss in manufacturing base and a loss of some of our productive capability that can be filled with the green-collar jobs of tomorrow. But it will only happen if we recognize the scale and scope of both the challenge and the opportunity.

I'm sure that in the fullness of time we'll learn that one or more of these seemingly promising technologies were dead ends. And that's the nature of innovation, and that's why we should spread our bets; we should not put our eggs in any one basket. Some of these will be grand successes, some of them will be average, and some of them will be abject failures.

We [USA and China] have a common responsibility with different numerical targets, and that's the situation ultimately we are going to have with China. We emit six times more per person than they do. It's hard to tell them to cut theirs in half right now until we start moving. Being the ostrich with your head in the sand and tail feathers in the air like some would have us to do while China continues to pollute is simply not an option.
