Effect of pluginhybrids with 90km range on oil consumption in Germany http://www.heise.de/tp/r4/artikel/26/26669/1.html
to keep it short:
if every car would be a plugin hybrid with a 90km electric only range, oil consumption in the transport sector of germany could be halved and germany needs to consume only 10% more electricity;
to keep the cost at todays levels (europe levels, which are 1,5-2 times as much then those in USA), the cost of Li accumulators has to be halved; (industry is even promising more)
the study also says, that the step to 100% electric cars would be more difficult,
{in my opinion this isn't needed, since this little bit of oil could be replaced by biofuels, synthetic fuels;}
to keep it short, it really seems that individual mobility will be affordable at todays levels even without oil; the study itself is good, our group did some verifications and we didn't find real weak points
