Fusion: yes, when eventually feasible.
Fission: maybe. It has high energy density. But uranium ore is very thin and needs to be refined a lot. Storage of spent fuel is problematic. Generally, it costs a whole lot. Even if I consider it green, I don't see it solving the most pressing problems - setting up nuclear energy is slow.
If fusion were ever to be feasible, would it also need to used mined uranium, or are there other fuel sources?
Current fusion (thermonuclear bombs) require a fission bomb trigger to start fusion in a lithium deuteride body, but reactors - absolutely not.
Fusion reactors do one of the following:
Short version: fusion needs fission only in warfare.
I love nuclear energy. Well maybe to strong of a word. I am extremely favorable towards it.
But we needed to go majority nuclear 10-20 years ago...
There are so many nuclear safety regulations and red tape (for good reason) that it makes new reactors being started now not financially profitable. Renewables are mugh much better until the current highly excessible lithium deposits dry up (tons of lithium in the world, but a tiny fraction of it is minable without decimating the environment)
But that brings me to my main point: energy providers are constantly for profit just like leacherous landlords. Basic necessities should be run publically in many cases. If you can get electric prices so low that it is almost free provided a large governmental investment (a mere tiny fraction of the military industrial complex budget) then you could literally turn the world around in 10 years. But that is a pipe dream that will never happen.
Oil companies control all of the energy decisions around the world and will sooner invest in renewables than nuclear.
