Which generates more energy: fusion or fission?

Answer 1

Fusion generates more energy per unit mass of fuel.

Since it takes a lot of energy to reach a sustainable fusion state, fusion reactions release three to four times as much energy as fission reactions do. For this reason, current power production relies on the (relatively) less energetic fission process.

Because fission only involves regulating a spontaneous process rather than starting a process with a very high activation energy requirement, it is comparatively easy to initiate and control.
