Sure. Cheap superconductors would also be a "black swan" for energy markets. They could enable trans-oceanic power lines for example, which would allow solar in Africa to power Manhattan at night. You could create a planetary power grid, which seems to me like something that would almost define a Kardashev type I civilization.
Fascinating. Never heard of this categorization of civilization technology before.
Apparently, according the wiki, in 2012 we were at type rating 0.724, presumably a large portion of that is non-renewable sources like coal/petroleum/natural gas.
Interesting that TypeII is almost a quantum leap over the TypeI - construction of a dyson sphere sounds like an almost unimaginably massive undertaking compared to blanketing the globe with solar cells.
