We shouldn't have stupid cars that use liquid fossil fuels. Come on, how outmoded is that? We have to get to the point where this is no longer a part of our experience.

Quite frankly, there is no answer to climate change without substantially, dramatically, increasing the amount of renewable energy in the global energy system.

This is probably the most difficult task we have ever given ourselves, which is to intentionally transform the economic development model, for the first time in human history.

I still do not understand why we don't have people on the streets every single day raising their voices for climate.

We cannot ask others to do what we have not done ourselves.

We have to get to the point where each individual, each corporation, each community chooses low carbon, because it makes fundamental sense. It should become a no-brainer.

World events do not occur by accident. They are made to happen, whether it is to do with national issues or commerce; and most of them are staged and managed by those who hold the purse strings.

Men are unwise and curiously planned.

When I was younger, things came so easily to me. It was just natural.
