  We present the results of numerical studies of supernova remnant evolution
and their effects on galactic and globular cluster evolution. We show that
parameters such as the density and the metallicity of the environment
significantly influence the evolution of the remnant, and thus change its
effects on the global environment (e.g., globular clusters, galaxies) as a
source of thermal and kinetic energy.
  We conducted our studies using a one-dimensional hydrodynamics code, in which
we implemented a metallicity dependent cooling function.
  Global time-dependent quantities such as the total kinetic and thermal
energies and the radial extent are calculated for a grid of parameter sets. The
quantities calculated are the total energy, the kinetic energy, the thermal
energy, the radial extent, and the mass. We distinguished between the hot,
rarefied bubble and the cold, dense shell, as those two phases are distinct in
their roles in a gas-stellar system.
  We also present power-law fits to those quantities as a function of
environmental parameters after the extensive cooling has ceased. The power-law
fits enable simple incorporation of improved supernova energy input and matter
redistribution (including the effect of the local conditions) in
galactic/globular cluster models.
  Our results for the energetics of supernova remnants in the late stages of
their expansion give total energies ranging from 9e49 to 3e50 ergs, with a
typical case being 1e50 erg, depending on the surrounding environment. About
8.5e49 erg of this energy can be found in the form of kinetic energy.
