Not at all. I think the world will still be dependent on gas regardless.  The electric cars   major challenge is costs. Battery technology is expensive, and because batteries in electric cars need to be able to hold massive amounts of charge to make the cars practical for most drivers, they have to be built using expensive materials, most of which are tough to procure. Because electric cars cost a lot to build.
 This industry (electric cars)  will not grow as much .. probably need another decade or so. for us  to see if it can really effect the oil industry.
