Mass can be destroyed to release energy. Relativistic energy is conserved as long as we define it to include the possibility of mass changing to energy. At extremely high velocities, the rest energy \(mc^2\) becomes negligible, and \(E = pc\).

What about intermediate cases?

Not only does energy have many important forms, but each form can be converted to any other. We know that classically the total amount of energy in a system remains constant. Relativistically, energy is still conserved, provided its definition is altered to include the possibility of mass changing to energy, as in the reactions that occur within a nuclear reactor.
