Probably, but there is another issue that is ignored. The manufacturing
process creates waste streams that must be handled. How nasty these are
compared to fly ash disposal with coal I do not know. I have not seen
anyone actually look at this.

A similar problem exists with electric cars. Besides the problems of
battery life/range, you have disposal of the batteries, manufacturing of
the batteries, and the extra load on the electric grid. Each will add
potential environmental issues. Whether they are worse than the problems
of internal combustion engines, again I have seen anyone actually
address.
