I'm a fiscal hawk. I vote against all taxes, but I do believe the environment, and climate change, is a bigger issue than fiscal deficits are as a risk to the nation.

The only way you multiply resources is with technology. To really affect poverty, energy, health, education, or anything else - there is no other way.

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.

Oil replacements and then efficiencies in engines and housing and the way we build houses is a very interesting market.

In the next 10 years, data science and software will do more for medicine than all of the biological sciences together.

Spreadsheets are fiction. Believing in what you're doing and what you're building is what's important.

Setting an aggressive enough carbon-reduction goal will result in an appropriate price for carbon and will help many a renewable technology. Consumer education will help. Most importantly, though, will be the continually declining cost trajectory of the real breakthrough in clean-technology costs driven by research and innovation. In the end, private capital is the real barometer of change.
