are electric cars really that green? obviously the power must be generated somewhere - much of it with coal.
but even if you assume that it is clean electricity (with the Niagara Power project and potential for wind and water generation, it isnt too great a leap), those big ol' batteries need to be manufactured and disposed of somewhere. both of those processes arent exactly clean or energy efficient.
is it possible that a hyper-efficient gasoline auto could be more environmentally friendly than electric cars (at least this generation)? i dont know, but it seems that it could be competitive.
for that matter, is CNG, clean diesel or LPG a better alternative? i dont know, im far from an engineer or environmental scientist. but should we be picking winners and losers for the marketplace at this point? id hate to dedicate resources to a technology that might not prove to be the best answer to transportation needs.

and of course, there are proven green infrastructure improvements that can be made now, with long lasting and relatively expensive off the shelf equipment - public transit!
