  The paper is devoted to an explanation of the accelerated rate of expansion
of the Universe. Usually the acceleration of the Universe, which is described
by FRW metric, is due to dark energy. It is shown that this effect may be
considered as a manifestation of torsion tensor for a flat Universe in the
realm of Teleparallel gravity. An observer with radial field velocity obey
Hubble's Law. As a consequence it is established that this is radial
acceleration in a flat Universe. In Eq. (\ref{24}) the acceleration is written
in terms of the deceleration parameter, the Hubble's constant and the proper
distance. This may be interpreted as an acceleration of the Universe.
