<span>nuclear fusion is observed in stars coming from the combination of two hydrogens to form an atom of helium. Fusion means combination of two or more elements. helium is known to fuel energy which in this case, the great sun which is more than a million Kelvin in temperature already today. hence the answer is true.</span>

<span>Radioactivity is the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei. Particles are emitted from the nuclei as a result of nuclear instability.
</span><span>
The radioactivity of an atom is dependent on the difference in binding energy .</span>
(comparing the before and after states, the binding energy of the <span>product nucleus and the binding energy of the initial decaying nucleus)</span>
Here are the ones that I know about
and can think of just now:
-- wind
-- solar
-- nuclear
-- tidal
-- hydro
-- geothermal
-- biomass
