  Finite entropy and energy are obtained for the horizon of a Rindler observer
on the grounds of the nonstatic character of the geometry beyond the horizon.
Edery - Constantineau prescription is used to find the dynamical phase space of
this particular spacetime. The number of microstates rooted from the ignorance
of a Rindler observer of the parameter $t$ from the nonstationary region is
calculated.
  We suggest that the gravitational energy density constructed by means of the
horizon energy and using the Holographic Principle is proportional to $g^{2}$,
similar with a result recently obtained by Padmanabhan and with the energy
density of the electromagnetic field.
