Oh well. You can call the Volt 'green' if'n ya like. 'Round here we call it BS ...
Sorry Doug...but you just haven't done you're homework on this one. They are not the ultimate solution, that's true, they are considered a 'bridge' technology designed to get us to hydrogen fuel cells 20-30 years on...
Fuel cells are a ways off...the infrastructure just isn't built out yet.
Studies have shown that the vast majority of driving is done locally, which would mean the Volt would very rarely use the gas engine. (Which btw is an extremely small & clean engine emission-wise.) However, its nice to know you can drive cross country in one if need be.
So...I'm all for driving around a car that has zero emissons 95% of the time, and keeps a sheikh's hand (in some country that doesn't like us very much), out of my pocket.
You're forgetting about wind, solar & hydroelectric...the fields up here are completely covered with wind turbines now. Besides coal fired electric plants (pound for pound) are much cleaner than all the trucks required to move & produce fuel, and all the emissions reduced by owning these types of cars...its win win.
Personally, as a 2nd vehicle I think they're a great option. True, I wouldn't buy one if I only had 1 car. I could literally drive one for weeks, and never use a drop of gas.
But it is a bridge...not an ultimate solution...but that ultimate solution is a long way off.
