I suspect the main reason fission is having a resurgence of popularity is because it maintains the current power structure of a rare large facilities controlled by a handful of actors. This has obvious advantages if you are a rich person concerned about keeping wealth concentrated into a few sets of hands.

Renewables are by their nature much more distributed in space, which makes them much harder to enclose and control in the way required to reproduce the current structure, especially as they are mainly being built by challengers who aren't really interested of forming monopolies with the fossil industry.
