To me it's not about the environment. It's about less dependency on oil.
Good to have alternate technologies. Also, like any emerging technology, you can't use current models and infrastructure to fairly compare. The whole thing will quickly develop and improve to address environmental concerns, be it cleaner electric generation, or more enviro-friendly battery technology etc. It's a step in the right direction.
