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.

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.

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

Tolerance is carved into the rostrum of the U.S. House of Representatives and intolerance should not be carved into the U.S. Constitution.

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

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.

If we had continued making progress at the rate we were during the Carter administration, we would be free of oil imports from Saudi Arabia today.
