I approached the bulk of my schoolwork as a chore rather than an intellectual adventure. The tedium was relieved by a few courses that seem to be qualitatively different. Geometry was the first exciting course I remember. Instead of memorizing facts, we were asked to think in clear, logical steps. Beginning from a few intuitive postulates, far reaching consequences could be derived, and I took immediately to the sport of proving theorems.

If other countries don't impose a cost on carbon, then we will be at a disadvantage...we would look at considering perhaps duties that would offset that cost.

While we cannot accurately predict the course of climate change in the coming decades, the risks we run if we don't change our course are enormous. Prudent risk management does not equate uncertainty with inaction.

So imagine a world 6 degrees warmer. It's not going to recognize geographical boundaries. It's not going to recognize anything. So agriculture regions today will be wiped out.

If there is a regulation that says you have to do something-whether it be putting in seat belts, catalytic converters, clean air for coal plants, clean water-the first tack that the lawyers use, among others things, and that companies use, is that it's going to drive the electricity bill up, drive the cost of cars up, drive everything up. It repeatedly has been demonstrated that once the engineers start thinking about it, it's actually far less than the original estimates. We should remember that when we hear this again, because you will hear it again.

Education in my family was not merely emphasized, it was our raison d'être. Virtually all of our aunts and uncles had Ph.D.s in science or engineering, and it was taken for granted that the next generation of Chu's were to follow the family tradition. When the dust had settled, my two brothers and four cousins collected three MDs, four Ph.D.s and a law degree. I could manage only a single advanced degree.

Just refrigerator efficiency saves more energy than all that we're generating from renewables, excluding hydroelectric power... I cannot impress upon you how important energy efficiency is. It doesn't mean you eat lukewarm food and your beers are lukewarm. You can still have it; you just make a better thing
