You may need small amounts of rare earth elements. Those are definitely a supply chain nightmare.

Not for solar, and not for most forms of Li-ion batteries.

You need them for solar inverters, but you also need them for the turbines like those used to generate power with geothermal/wind/hydro/nuclear/etc.

Erbium perhaps for some power semiconductors, but in very small amounts.

What's the use in turbines? Most generators associated with turbines don't use permanent magnets.
