  J. E. Hirsch [EPL 130 (2020) 17006] claimed an inconsistency between
thermodynamics and the theory of superconductivity. We argue that he overlooked
a crucial term which determines the supercurrent dynamics and ensures energy
conservation by providing an internal energy source for the Joule heating.
Thermodynamic consistency is restored by restoring energy conservation. The
correct dynamics is given by Maxwell's equations in the superconductor.
