Electric cars could drive the future – but not without old-fashioned vehicles

New report finds 'that the energy of 87% of vehicle-days could be met by an existing, affordable electric vehicle' - but that's not quite good enough

Electric cars could take over most driving necessities tomorrow, according to a group of scientists at the Massachusetts Institute of Technology, but they'll need the help of internal combustion engines to do it.

Using travel surveys and global positioning data, the MIT team has evaluated the possible widespread use of electric cars, and has found that grids could easily support today's cheap electric cars, and that the cars themselves can already meet drivers' requirements almost nine times out of 10.
