The uncertainties are of a different order for geothermal as it is a much more immature technology.
That assumes that you are talking about using it for really substantial power generation, which means hot dry rock.
A number of problems have been encountered, notably getting just the right amount of fractioning in the rock to allow the water to flow through to the well which extracts it, and that problem will be different for every field.
At present it also costs a fortune - that may change, but we are talking about uncertainties.
You also can't build a geothermal plant just anywhere, and practically speaking the areas where you can hope to build them are relatively limited.
Iceland seems to be at the leading edge for geothermal. It is one of many renewable energy resources that I think we need to develop in order to keep the electric grid functioning. It will be a different set of technologies for each locale. I really cannot see nuclear at 17% of world production. Financing, adequate cooling water coupled with climate change, containment building production capacity these are just the direct difficulties The energy problem needs many diffuse solutions based on local resources and needs, not a handful of concentrated one designed to keep the energy fat cats engorged.
