That's a good point: peak when electric vehicles become mainstream. Is transportation the main driver for crude oil? How about plastic?

I'd love to see solar take a dominant role in energy—the question I have is will PV technology and geographic climate constraints push solar forward fast enough?

Writing a response to you also made me think about energy storage. I think that'll play a much larger role and I didn't think of it earlier.



The energy storage issue for renewable energy can be solved with today's technology just by making the grid bigger. Think of distribution networks spanning multiple timezones and geographic region.

For plastic i believe the recycling rate is already very high.


That's interesting, I didn't know; what are some companies betting on energy storage?


More than 80% of U.S. petroleum consumption is transport fuel:

Thanks for this—I need to read up!


If it is a major economic activity, it is a safe assumption that the U.S. gov is collecting statistics on it. The pain in the ass is finding where they publish them.
