Religion asks you to believe things without questioning, and technology and science always encourage you to ask hard questions and why it is important in science and technology. So I was always interested in science and technology.

For electric power generation, we are very optimistic about solar-thermal technology, and we’re intrigued by the potential of enhanced geothermal energy to replace coal-based power generation. Traditional carbon capture and sequestration-based coal power generation is somewhat unlikely to be competitive.

It doesn't matter what your probability of failure is. If there's a 90% chance of failure, there's a 10% chance of changing the world.

Imagine the world of mobile based on Nokia and Motorola if Apple had not been restarted by a missionary entrepreneur named Steve Jobs who cared more for his vision than being tactical and financial.

The world is hung up on food-based biofuels. Not only are they the wrong thing, they're the uneconomic thing.

I do not know what got me interested in technology. What was very clear to me very early on was that I was not interested in religion and that naturally increased my curiosity about science and technology, and I fundamentally believe the two are conflicting.

As for companies invested in the space - I think its important to distinguish between a good investment and a material climate change technology - you can have the first without the second, even in the "clean tech" space.
