That's wrong. Hydro is a clean, renewable form of energy. You can make an argument about the environmental impact of the dams, but that horse left the barn a long time ago... previous generations made the decision to flood northern lands and build the dams. So for better or for worse we now have hydro... how does it not make sense to use the clean energy we have either way to replace internal combustion engines?
Also, manufacturing plant and delivery related emissions are irrelevant since you're going to get that type of environmental overhead with any type of vehicle. What matters here is the impact of the 20 years that the vehicle is likely to be on the road.
The battery issue in terms of manufacturing and disposal is a fair criticism, though.
