Query: On the energy of a non-singular black hole solution satisfying the weak
  energy condition   The energy-momentum localization for a new four-dimensional and spherically
symmetric, charged black hole solution that through a coupling of general
relativity with non-linear electrodynamics is everywhere non-singular while it
satisfies the weak energy condition is investigated. The Einstein and M\{o}
ller energy-momentum complexes have been employed in order to calculate the
energy distribution and the momenta for the aforesaid solution. It is found
that the energy distribution depends explicitly on the mass and the charge of
the black hole, on two parameters arising from the space-time geometry
considered, and on the radial coordinate. Further, in both prescriptions all
the momenta vanish.In addition, a comparison of the results obtained by the two
energy-momentum complexes is made, whereby some limiting and particular cases
are pointed out.
