Ugh no thanks! Electric cars are a nasty fad that offer no vehicular, monetary or ecological benefit whatsoever over the internal combustion engine. I think you need to look a little further into the future for your comparison
I know
almost everyone here hates my posts, but i have to do it.
As of now, electric cars have no vehicular or monetary benefits, that's true. But the "has no ecological benefit" makes me want to hack the forums (even if it's most probably not possible and i will never success, i can try).
As you know, cars and almost every transportation uses oil or derivates (plane, ships, cars, bus, some trains, tir, bla bla bla). The fact is that we use the 95% of the oil (petroleum? don't know the exactly english translation for this) to move stuff. We use the remaining 5% to build pens, imacs, fragances, almost everything of what was invented (or went on mass production) in the last 50 years.
By supposing we have 20 years left of petroleum, in 2030 we will no have personal computers anymore. If, from tomorrow, we start using the oil only for derivates, "the 5%" we will have (100/5)*20 = 400years where we can still make pcs.
By having only electric cars we can centralize the energy production, where the performance of the energy transformation is better. Of course, we will still lose during the transport of the electric energy, the reloading of the batteries and so on, but it will never be as bad as it is know. For example here (it:
http://it.wikipedia.org/wiki/Motore_Diesel) it says that the efficiency of a Diesel engine is of the 15%. That means (i think you know it) that the 85% of the energy is used to heat up the engine and make noise, while the 15% is mechanical energy.
I hope that this post has resulted useful to someone.
]. vB and IPB seem to be at best hybrids still dealing with the internal combustion engine and spark plugs. 
much much more in the future.
