Answer: 2 — Fission reactors are used to generate electricity, but fusion is not yet practical enough to be used.

Explanation: Commercial nuclear power today comes from fission (splitting heavy nuclei) in hundreds of reactors worldwide. Fusion (combining light nuclei) has been demonstrated in experiments but has not yet been made practical or economical for continuous commercial electricity generation.
