Whatever my current beliefs are, on any topic, they're all open to being changed by the right facts and the right evidence.

You have to be able to generate usable energy without greenhouse gas emissions and you have to be able to do it cheaply if you want people to choose that approach.

If you want to feed the planet and keep the forests we have, you need to be able to grow roughly twice as much food per acre around the world. How do you do that? New technology.

That, to me, is a kind of brilliant environmental ju-jitsu - using the energy of the market and the profit-motive to get businesses to invest in preserving and improving natural systems.

Whatever my current beliefs are, on any topic, they're all open to being changed by the right facts and the right evidence.

We have climate change caused by greenhouse gas emissions, mostly from human power and transportation infrastructure. At the same time, we have 2 billion people who live in energy poverty.

Technology is incredibly powerful. And in many ways, the sky is the limit in terms of what you can actually accomplish with the right science and the right technology.
