for sure, but I don't see this as the massive Tech/Business challenge that it has been presented to be.

Cars are only driven, on average, something like 4% of the time. All those batteries in cars attached to a smart vehicle/smart grid provides for lots of options to smooth out the daily supply/demand curve and max use of intermittent sources like solar. Local sourcing of power(residential solar) are very promising, particularly the really attractive tesla roof..as costs decrease you could install that stuff everywhere. I think those type of shifts could occur over a 10-15 year period once the $$$ demand is in place.

Even if you shift your transportation to electric and power it with worst-case-scenario coal plants, you are still getting huge efficiency/carbon reduction gains. I do believe we can/will continue to ramp industrial solar+battery like crazy and we will see more nuke plants over the next 15 years. I don't see the insurmountable challenges that some describe.

I'm confident this will get sorted out as there doesn't appear to be much supply of new ICE vehicles planned 10 years from now, all the car companies are aggressively phasing out ICE vehicles. Rollout of the grid will likely get the same level of investment as early internet/fiber deployments. Lots of investments coming on top of the significant investments that have already been made. Tesla and VW have both invested Billions in buildout of charging networks.
