If you're not limited by the need to move around, then lithium doesn't make as much sense for power arbitrage technologies. There are literally dozens of such technologies capabale of storing intermittent solar/wind inputs in physical or chemical forms that can be pumped back out onto the grid as needed.

It's so ridiculous to think that human civilization would collapse just because we will eventually run out of stuff to dig out of the ground and burn, when the biosphere has been humming along on sunlight for about three billion years. Why is this so hard to explain to people?

I agree, but we also need a storage system that can move around, and the aggregate scale of that is inherently more than enough for grid storage. This is why I'm not going to rule out hydrogen despite it having not worked out even back during the 1973 OPEC fuel crisis when alternatives were desperately needed and nuclear power (which is useful for among other things electrolysis) was The Future.

(Also, on paper one doesn't need any grid storage, if only we could get governments to cope rates on a planetary grid. Texas doing it's own thing and Japan having two frequency zones shows how hard this would be in practice, but in principle it can work just fine).

How much energy does all of humanity use compared to the rest of the biosphere? Genuine question not intended to be leading, it's a very interesting point.

It doesn't matter, the energy provided by the sun is mind numbingly insane.

The total sunlight that hits the Earth in 2 minutes is more than whats needed to power the entire world for a year.
