i dont think highlighting a major obstacle to adoption is dismissing. there are presently MILLIONS of drivers who would not have access to their own charge point, with a very very different usage profile to existing fuel stations.

still need to generate a large amount. the current energy use for transport is about 40% total consumption. renewables are about 20% generation. even with clever charging/discharging theres a large gap to fill...
