The primary process responsible for generating the immense energy within the core of the sun is nuclear fusion. Specifically, it is the fusion of hydrogen nuclei into helium nuclei under extremely high temperatures and pressures.

Nuclear fusion is a process where light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy. In the Sun, this process is primarily the proton-proton chain, where four hydrogen nuclei (protons) ultimately fuse to form one helium nucleus.

Nuclear fission is the splitting of heavy atomic nuclei, typically used in nuclear power plants. Atomic collision and excitation are processes involving electrons changing energy levels, which can release energy but are not the main source of power for stars.
