Does it, though? Assuming 80% of energy use is fossil and fossil has a 50% loss, if all that fossil were to transition to ~100% efficient electricity[0] we'd already be at 33% of our renewable electricity needs. That's quite a bit more than the 20% the "80% fossil" seems to suggest!
"One-third done" sounds an awful lot like we're going to start seeing optimistic "we'll be halfway there at the end of the decade" headlines soon...
[0]: Things like the grid and car batteries don't operate at 100% but closer to 95%, but things like heat pumps operate at 300% efficiency, so I reckon that'll more-or-less cancel out for back-of-the-napkin math.
Yes we're not done yet, but renewable only started gaining share again around 2010, and how quickly solar/battery is being deployed is really impressive.
