> CO2 capture is an area of active research and it's entirely possible that advances there will make Tesla and Solar City moot.

I don't know how likely that is. Even if carbon capture comes through, the low hanging fruit of fossil fuels are gone so now we have to get more invasive in harvesting the hard-to-get ones (strip mining, fracking, etc). It's likely that even with C02 emissions taken care of that we'll want electric vehicles and renewable power in general.
