Are electric cars really more environmentally friendly?

I haven't looked through the maths here, but I did notice that the comparisons seem to be based on calculating efficiency of the entire delivery system for a fully charged battery (mentioning heat/mechanical/AC/DC/voltages).

I think it should be pointed out that even though crude oil contains a great deal of potential energy, distilling petroleum fuels from it, plus transporting & storing them goes along way to offsetting that figure in just the same way as talk about the electricity generating network does. -Comparitively, coal has to be dug out of the ground. But it doesn't need to be distilled as well!

To bring us back to Paul's (who started the thread) question:
Electrically powered (by which we mean chemical battery storage) could be infinitely more environmentally sustainable than our current mainstream solutions IF the energy came solely from a renewable resource such as PV solar.

Thanks for the link, Pumblechook. I'm away for a few days, will look at it on return.
Based on you're description of the Dickens character, I could probably out-Pumblechook you!

Perhaps a way round the battery problem on future electric vehicles would be to develop a standard sized slot in battery pack that could be exchanged for a charged pack at the equivalent of a petrol station.
