When you take the rare earth metals required for the motors and batteries, add in the energy to produce those batteries then to dispose or hopefully recycle the batteries the savings in energy over the life of vehicle is negated.
I agree there are conflicting opinions as to how much, but everything I have read shows most or all + of the savings are lost.
From what I have read Solar is somewhat similiar, although they have gotten much better.
An article I read a few years back showed that over the life of the solar cell, it will only procduce about 80 to 90 % of the energy used to produce them.
I do not agree, but it was written by a scientist from one of the producers of solar cells.
