It takes carbon to produce a BEV as well. And somehow BEVs are a lot more expensive (up to 40% more, when there are no subsidies) to produce than HEVs, which suggests more resources and energy is spent on producing a BEV.

For many people that initial price difference is high enough that buying a BEV instead of HEV makes totally no economical sense - so likely the lower emissions from usage are not going to offset higher emissions on production, for the whole lifetime of a car.

The BEV economics work only if you drive really a lot on long distances, but that's unfortunately the area where BEVs lose to HEVs on convenience.

Not one that's already on the road.
