@ Ashton Black (was: Re: What happens to the grid ...)
You've avoided the obvious.
We already have rotating brownouts. The local grid will fail if a large percentage of the population uses said "green" plug-in transportation.
Battery powered transportation simply doesn't scale.
Fuck CO2, that's a red herring. H2O is a far worse greenhouse gas. Don't believe me? Try running a CO2 scrubber in a greenhouse[1]. Take note of temperature. Then run a desiccator, take note of temperature. The high H2O/low CO2 environment will be much hotter than the high CO2/low H2O.
[1] To say nothing of the fact that CO2 is plant food ... and H2O contributes to rotting.
