Electric Vehicle Study Praises Tech, but There's a Catch

In the following video, Motley Fool industrials analyst Blake Bos takes a look at a study done by Scientific American, which says that an electric vehicle can drive 6,500 miles on one gigajoule of energy invested into producing the electricity required to propel the vehicle. This was nearly twice the distance that a gasoline-powered car could go on the same amount of energy. But, there's a catch. Blake tells us what the caveat is, and why electric vehicle investors may have a while to wait before we crack this nut.
