OK Arg not much different to my numbers really. However these "average" numbers are hopeless for planning. Charging has to be 24 hr availability as otherwise any trip longer than 60 miles is no longer possible without an overnight stay. I can see motorway services offering charge at £5 per kWh already! So the non-green conventional generating capacity has to meet another 10GW peak load on a dark wet windless day, and that is an "average figure", every house with 4 cars taking an extra 120A at night might also be amusing for the distribution infrastructure, as might every house taking 30A extra, it would lead to total failure immediately because each 50 - 60 houses usually have one 600A fuse! Only 5 more nuclear power stations need to be built in the next 20 years then. It is not sensible to suggest a plan which requires that all the domestic electrical infrastructure be hugely uprated, or plan on the basis that only 1 in 10 houses will have one car and the rest none. The missing information is still "who pays" and sounds like the magic money tree again! Of course this could just be an aspiration and not really on the table at all. I estimate that this plan costs £500 Billion to £1 Trillion at today's prices, so not a loose change job.
Changing the subject slightly, it has now been admitted that the high pollution levels in Oxford Street and elsewhere are caused by buses and taxis and only a little by private cars, so this plan seems to be solving a non-problem. Diesels can be made very clean with Ad-blue or similar, such as tier 6 lorries, so more misinformation is being used to promote a political viewpoint. I have still failed to find any papers which actually analyse very low level NOx toxicity, so there doesn't seem to be much science either. Good here isn't it!
