Healing is a moral thing to do.

We must start... rebuilding our cities around energy efficiency and human needs, rather than around the car and wasted energy.

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.

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

We could never light another match, and if China continues to build one coal-fired power plant a week, we are doomed. China is going to have to have new technologies made available to it to stop this. They're not going to live in poverty.

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.

The need to help spread democracy and the ability to do that will be much greater if we break this addiction to oil, which gives the oil princes and sultans the power in the Mideast.
