The potential for alternative energy sources, mainly solar and wind power, to completely replace coal and gas for utility generation globally is, I think, certain. The question is only whether it takes 30 years or 70 years.

We live on a finite planet. We have finite resources, and we're running out of good, arable land.

It is better to be lucky than good, but of course appropriate to aspire to both.

There is a lot of pain still to be had in the equity markets, particularly aimed at the risky end of the spectrum. We think the fair value on the market is about a third lower in the U.S. . .

The world is using up its natural resources at an alarming rate, and this has caused a permanent shift in their value. We all need to adjust our behavior to this new environment. It would help if we did it quickly.

I like to be right. I try not to miss the big ideas, forget the little ones, and try to get them right. End of job description.
