If you don't have sustainable energy, you have unsustainable energy. The fundamental value of a company like Tesla is the degree to which it accelerates the advent of sustainable energy faster than it would otherwise occur.

In just a few hundred years, we will have to cover the entire surface of the Earth in solar cells if we want to continue to grow our energy usage.

India has now graduated from megawatts to gigawatts in terms of renewable energy production.

I really do encourage other manufacturers to bring electric cars to market. It's a good thing, and they need to bring it to market and keep iterating and improving and make better and better electric cars, and that's what going to result in humanity achieving a sustainable transport future. I wish it was growing faster than it is.

It really matters whether people are working on generating clean energy or improving transportation or making the Internet work better and all those things. And small groups of people can have a really huge impact.

I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that.
