I did research just before posting that.  https://minesafety.wv.gov/historical-statistical-data/production-of-coal-and-coke-1863-2013/

Now, lets examine your site.  First this chart:



A typical example of non-rational persuasion.  Notice the downward trend, purposed to give visual reinforcement to the claim made.  Except that downward trend happened under Obama, not Trump.  Once Trump took over, coal jobs stabilized up until Covid when everyone was forced out of work.  And notice also that this chart is nationwide, and not specific to West Virginia which was your original claim.  So maybe you should give your left wing sites a bit more scrutiny before pushing such nonsensical propaganda.

The point made was that lithium mining is both highly exploitive of third world workers and also environmentally damaging.  And solid state batteries do nothing to reduce that.

That would be Factorial Energy.  They still use lithium in their solid state batteries.

The largest Ev solid state battery plant in the world was just built in Massachusetts

And here's how all that cobalt is mined:



Personally, I'd rather drive a car that was fueled with petroleum products derived from a mine with a much smaller environmental footprint than a lithium mine, and that wasn't built with the fruits of child slave labor - African child slave labor, at that.  But then, I'm not a liberal.
