  We consider a scenario of the gravitational collapse of the
Oppenheimer-Snyder dust cloud with spatially constant matter density. Given a
closed two-surface within the star, three versions of the quasi-local energy
are investigated. We show that, during the collapse, (i) the Geroch energy of
the surface is nonpositive and increases to zero; (ii) the Hawking energy of
the surface is monotonically increasing and approaches to the Hayward energy of
the initial surface; and (iii) the Hayward energy of the surface is conserved
and remains positive. These results have no restrictions on the topology and
the symmetry of the surface.
