Thank you all for this continuing discussion.
I'm sure all of us agree that an electric vehicle drive train is far superior to that which includes an Internal combustion engine.
The state of batteries as electrical energy storage is another matter at this point in time.
Lithium Ion chemistries have been a HUGE improvement over other, less efficient, less robust options however there certainly are cost, battery longevity as well as environmental concerns while the production of such systems ramps up.
IMO: Hydrogen as an energy carrier/method of storing electrical energy and ultimately hybrid BEV/FCEV vehicles are going to be part of the equation very soon.
The other salient issue here is the de-centralization of cleaner, more efficient energy production and the stationary storage capacity which will drive development in that direction. Frankly, if the Big energy monopolies were doing a better job of transitioning to clean energy infrastructure this would be less of an issue. Unfortunately the baggage most them bring to the table precludes their efforts toward that. Don't get me wrong there will always be a need for grid power going forward in the industrialized world.. just not as big a need.
As more of us become power producers via rooftop solar, other micro-grid developments the utility companies large and small will be confronted with a very real need for Distributed Energy Resource (DER) planning. So-called smart meters and the time-of-use metering they enable are just the beginning for that new paradigm.
We live in interesting times and I'm very pleased and grateful to be sharing the early stage adoption with all of you good people.
Thank you, .. AJ
