If your electricity comes from coal or oil, I don't really see the where it's perfect solution.
As for the hybrids, I was not pleased when Master told me about the class he took to repair hybrids. If they are working near the batteries: The first guy wears four pairs of gloves. Nytrile, cotton, rubber and leather in hopes of not conducting electricity. A second guy stands behind him with a fiberglass hook, so he can pull the first guy's dead body off the batteries in the case of making a connection.
Somebody was bullshitting. While the batteries do push a lot of amps the voltage is low and almost any decent insulator is sufficient to protect a person. People work barehanded safely around much more dangerous electrical equipment every day. the big key is to wear insulated shoes so there isn't a low resistance path to ground through the body.
I guess I am not sure what "low voltage" means. If you read this link, http://www.autoserviceprofessional.com/article/91647/Electronic-air-conditioning-An-overview-of-systems-found-in-today-s-hybrid-vehicles?Page=1 even the A/C compressor runs at 200+ volts. I guess compared to a couple of KVs, this is not bad, but it is ample voltage to make the use of a curling iron unnecessary. And if you read Toyota's dismantling procedure they seem quite concerned themselves https://www.google.com/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=11&cad=rja&ved=0CEcQFjAAOAo&url=https%3A%2F%2Ftechinfo.toyota.com%2FtechInfoPortal%2Fstaticcontent%2Fen%2Ftechinfo%2Fhtml%2Fprelogin%2Fdocs%2Fpriuscdisman.pdf&ei=u3vFUPjoA8mpqwGMiYDoCA&usg=AFQjCNGDf6EEzDPu-q9h--glYZwn51VlNQ
Since the Insight, we have had what most of us would consider high voltage inside vehicles (~200V). While it might not require 13 sets of gloves and a guy with a hook behind you to collect the dead body, those battery packs have enough juice that at that voltage, they will not only cook one's Goose, they will turn it into Crispy Duck special #5.
I am not an owner of a magic crystal ball and hence I cannot foretell the future. Maybe it will be electric cars in their current form, maybe it will be fuel cell vehicles with electric motors or some sort of a Hydrogen car, but it is a good bet that 200 years from now we will not have cars with internal combustion engines like the ones we have today. Then again, in 200 years, I won't care. For what happens between now and then, we will have to wait and see.
I am not sure it will be a market only evolution. I remember reading (as someone eluded to) that many countries in the EU coaxed by the coal loving Geeeermans, lowered taxes on diesel to help promote it's use (causing the EU to run at a Diesel fuel deficit as I understand it). Here in the US, now that we have switched to ULSD (ultra low sulfur diesel) the economics have not worked out to the favor of diesels especially as GDIs (Gasoline Direct Injection) and Miller cycle engines are re-examined. With combustion models getting better, the invested infrastructure, and their simplicity compared to hybrids, ICE vehicles are not yet ready to give up the spirit.
That is what I think, but YMMV,
