Not with enough batteries or hydroelectric storage.

As I understand it, the batteries are dangerous also, being lithium or sodium. These are potentially city block-size Note 7s, right?

  Not when engineered properly. https://electrek.co/2016/12/19/tesla-fire-powerpack-test-safety/ https://electrek.co/2016/12/19/tesla-fire-powerpack-test-saf... EDIT: Wide swaths of land aren't off limits to humans for decades when a lithium ion substation burns down.

    So are reactors, in fact everything is bulletproof if you only count the successes.

    Interesting. So, it's much less impressive than a substation transformer explosion; I had expected it to be similar. A "transformer substation explosion" scenario is a good base for a comparison, since we have a lot of experience with them, and the scenario (within a city, near other buildings, with high-voltage wiring) is similar.

  AFAIK the danger of Note 7s is mostly due to the small size of these batteries, i.e. how close anode/cathode are times the energy density times the amount of space it has for thermal expansion. In infrastructure sized batteries this isn't really a big issue.

How many greenhouse gasses are created from manufacturing batteries?

  Here you go [1]. You're looking for the blue part of the bars. Compared to operating and manufacturing the rest of the vehicle it seems rather negligible, i.e. switching to EVs (and plugin hybrids) and then switching the power grid to something Carbon neutral should be your first concern, only then should we think about how to optimise the footprint of batteries.

Edit: As a bonus, here's a map showing how much the grey part of the bar reduces depending on the country you live in: https://docs.google.com/spreadsheets/d/16K4gNhy_AN8Eg4Ov3z7pF_dgON1oObkHQ8Px5I73Hvc/pubhtml https://docs.google.com/spreadsheets/d/16K4gNhy_AN8Eg4Ov3z7p...
