  It is well-known that one of the most interesting and challenging problems of
General Relativity is the energy and momentum localization. There are many
attempts to evaluate the energy distribution in a general relativistic system.
One of the methods used for the energy and momentum localization is the one
which used the energy-momentum complexes. After the Einstein work, a large
number of definitions for the energy distribution was given. We mention the
expressions proposed by Landau and Lifshitz, Papapetrou, Bergmann, Weinberg and
M{\o}ller. The Einstein, Landau and Lifshitz, Papapetrou, Bergmann and Weinberg
energy-momentum complexes are restricted to calculate the energy distribution
in quasi-Cartesian coordinates. The energy-momentum complex of M{\o}ller gives
the possibility to make the calculations in any coordinate system. In this
paper we calculate the energy distribution of three stringy black hole
solutions in the M{\o}ller prescription. The M{\o}ller energy-momentum complex
gives us a consistent result for these three situations.
