Electric cars keep coming and going, coming and going, coming
  and going.

  Find the guy that makes the perfect battery and THEN it'll be
  possible.

  But even then... by supporting electric_ONLY, one is supporting
  coal, at least in the USA.

  There's no perfect system of course. Down here, in a nearby
  community (Marco Island) is a couple of guys that convert fancy
  cars into using cooking oil from restairants into fuel and they
  make a decent living at it.

  So as long as people are willing to eat fried foods, there will
  always be fuel available tongue emoticon

  My answer: Stay home as much as possible.
