It's not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it's a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere.

We have this handy fusion reactor in the sky called the sun, you don't have to do anything, it just works. It shows up every day.

I'm extremely confident that solar will be at least a plurality of power, and most likely a majority... in less than 20 years.

I don't spend my time pontificating about high-concept things; I spend my time solving engineering and manufacturing problems.

I wouldn't say I have a lack of fear. In fact, I'd like my fear emotion to be less because it's very distracting and fries my nervous system.

If you think back to the beginning of cell phones, laptops or really any new technology, it's always expensive.

As you heat the planet up, it's just like boiling a pot.
