  We present preliminary results on the energy budgets of clouds in
two-dimensional numerical simulations of the interstellar medium. Using an
automated cloud-identification algorithm, we calculate the gravitational,
internal, kinetic and magnetic energies of the clouds. We find that, within a
dispersion of roughly one order of magnitude, the gravitational energy in the
clouds is balanced by the remaining energies. Furthermore, within the same
dispersion, there appears to be equipartition between the kinetic and magnetic
energies.
