Tesla has pushed the needle but the automotive was trending towards electric before Tesla. How much energy have the on grid batteries saved?

It isn't an outlandish thing to say that those companies deliver a disproportionate amount of hype to results as other companies in the same space.

A few companies had built extremely compromised electric vehicles (Leaf, e-Golf, etc) with anemic range. No one built a 200-300 mile range electric sedan with the best in-class performance and best safety features seen in an auto to-date. (speaking of crash safety, not Autopilot).

Asking how much energy the on-grid batteries have saved is a non-sequitur. That's like asking how much energy Tesla automobiles have saved. Probably very little, but that is irrelevant in the grand scheme. The short-term (1-2 yr) question of energy saved doesn't matter. The long-term (10-50) question of "is this pushing the entire industry in a better direction" is the important question. I think it is Yes for on-grid battery storage, as it is Yes for Tesla automobiles, as it is Yes for reusable rockets for space transit. Must take the long view.
