The undeniable fact is that humans are very electricity hungry. Cheap electricity opens up tons of downstream benefits.

I am envisioning something like an international market for clean electricity. Something like an internet for power. This would enable developing countries to leapfrog dirty methods like coal, similar to how many countries leapfrogged over credit cards and cheques we still have in the US. Of course the UHVDC technology may not be ready for it yet.
