Indeed.

Somewhat solved, yes - but the "planetary power grid" scenario that
Bill C. envisioned would require its deployment on a much larger scale
than at present, and in manners outside the scope of present capability.
(The Pacific DC Intertie operates at +/-500kV on overhead wires, but we
don't have multi-megavolt undersea power cable technology - yet...)
