世界需要务实的解决方案，而不仅仅是理想主义的愿景。

You see, in the final analysis, it is between you and God; It is never between you and them anyway。

——2000年10月18日出席西雅图一次会议时的发言

Sustainability isn't an option; it's a necessity for the future of energy.

I don’t live in the past. I don’t live in the future. I live now.

大约99%的时候，最佳时机就是现在。
