Geothermal has the same problem as nuclear: it's a low operating cost, high fixed cost energy source. So it either operates in baseload mode or it gets much more expensive. It does not play very well with renewables.

It might make sense for high latitude small communities, since it scales down better than nuclear. It also should work better in cold climates, which helps in extracting work from lower grade heat. Perhaps it can complement solar, which could help compensate for lower efficiency of geothermal during the arctic summer.
