Fission energy and fusion energy are generated by electromagnetism and the strong nuclear force. …

…asteroid mining, from the moon (see helium-3), and from a Dyson sphere though the latter options are currently far beyond the capability of current human technological mastery. Even more speculatively and therefore in the realm of near pure fantasy; the accretion disc of a black hole can convert about 50% of the mass energy of an object into radiation, as opposed to nuclear fusion which can only convert a few percent of the mass to energy.
