Actually, no. Let's think this through. Where does electricity come from? Solar or hydro? Great, buy a Nissan Leaf. But most electricity comes from coal. So, in that case… burning gasoline is better for the environment.
Here's the article that led me to think about this.
[UPDATE (a few hours later): I had written "Prius" but it occurred to me that this is ambiguous, since a Prius is technically a hybrid, not an electric car, and thus is just a new model for burning gasoline. I have altered the title and post to reflect this – but there's no majorly iconic electric vehicle, yet. I chose the Nissan Leaf because it's one I happened to have seen recently here in Korea.]
