  The aim of this paper is to evaluate the energy distribution of some 2+1
black hole solutions applying the Landau-Lifshitz and Weinberg definitions. The
metrics under consideration describe the charged black hole, the solution
coupling to a static scalar field and the static and circularly symmetric exact
solution of the Einstein-massless scalar equation. Further, we compare the
expressions for energy with those obtained using the Einstein and Moller
prescriptions and give a discussion of the results.
