Local companies don't have to internalize their costs, and few actually do, but they tend to more often because the owners live there and they have to show their face in town, and their kids play with other kids.

Interestingly, the oil companies know very well that in less than 30 years they will not only be charging very high prices, but that they will be uncompetitive with renewables.

We assume that everything's becoming more efficient, and in an immediate sense that's true; our lives are better in many ways. But that improvement has been gained through a massively inefficient use of natural resources.

What a great time to be born! What a great time to be alive! Because this generation gets to essentially completely change the world.

Healing the wounds of the earth and its people does not require saintliness or a political party, only gumption and persistence. It is not a liberal or conservative activity; it is a sacred act.

I'd rather fail at something important than succeed at something trivial.

Don't be put off by people who know what is not possible. Do what needs to be done, and check to see if it was impossible only after you are done.
