  Superbubbles (SBs) are amongst the greatest injectors of energy into the
Galaxy, and have been proposed to be the acceleration site of Galactic cosmic
rays. They are thought to be powered by the fast stellar winds and powerful
supernova explosions of massive stars in dense stellar clusters and
associations. Observations of the SB 'DEM L192' in the neighboring Large
Magellenic Cloud (LMC) galaxy show that it contains only about one-third the
energy injected by its constituent stars via fast stellar winds and supernovae.
It is not yet understood where the excess energy is going, thus, the so-called
'energy crisis'. We show here that it is very likely that a significant
fraction of the unaccounted for energy is being taken up in accelerating cosmic
rays, thus bolstering the argument for the SB origin of cosmic rays.
