Occasionally, I would focus on a particular school project and become obsessed with, what seemed to my mother, to be trivial details instead of apportioning the time I spent on school work in a more efficient way.

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.

I think the Caribbean countries face rising oceans and they face increase in the severity of hurricanes. This is something that is very, very scary to all of us. The island states in the world represent - I remember this number - one-half of 1 percent of the carbon emissions in the world. And they will - some of them will disappear.

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 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.

The biggest gains, in terms of decreasing the country's energy bill, the amount of carbon dioxide we put into the atmosphere, and our dependency on foreign oil, will come from energy efficiency and conservation in the next 20 years. Make no doubt about it. That's where everybody who has really thought about the problem thinks the biggest gains can be and should be.
