Where are those numbers from? Wikipedia[0] states 8.90% in 2002 to 12.22% in 2012. (Edit: I see we're agreed on that.) Again, that's percent of the total electrical energy generation, not the entire energy budget, which is much higher.

I'm fairly optimistic that we'll end up using electrical vehicles down the road. But it's a long way off from becoming a sensible alternative; it'll take a long time to satisfy the current electrical energy requirements by renewables, and adding the transport budget essentially doubles the amount required.

And people are deluding themselves if they think they're being environmentally responsible by driving around a Model S. Maybe if you buy a Model S and don't drive it.

Electric vehicles aren't going to flood the market overnight, just as renewable energy isn't going to suddenly become our primary source of energy. These things take time and money. The more traction we give them, the more attainable they will become.

Environmental responsibility isn't possible when you ignore hard facts about the future. By the time I reach old age there will be 2 billion more people on this planet. They are capable of much more damage than we are.
