Are you saying that the main problem with battery electrics is also that most of the power it uses is not renewable?

You can have it at home, though it is very expensive. But prices are dropping more quickly than that of of, say batteries. Right now, there is NO silver bullet. > > >> On Wed, Jun 25, 2014 at 10:20 PM, Mark Abramowitz via EV <[email protected]> >> wrote: >> Old news. >> >> http://www.arb.ca.gov/planning/vision/docs/vision_for_clean_air_public_review_draft.pdf >> >> Sent from my iPhone >> >> > On Jun 25, 2014, at 6:06 PM, Cor van de Water via EV <[email protected]> >> > wrote: >> > >> > - this is news to me.
