  Recent claims in the literature (Bressan, Chiosi & Fagotto 1994) that the
epoch describing the onset of galactic winds in spheroidal star systems has
been severely overestimated in the past, due to the neglect of energy deposited
in the interstellar medium from stellar winds, is evaluated in the light of a
more conservative approach to modeling the input of thermal energy to the
system from massive stars undergoing mass loss. Applying the most recent models
of stellar kinetic energy deposition, coupled with reasonable assumptions
regarding the efficiency of thermalisation, it is shown that contrary to the
aforementioned study, the influence of stellar winds in driving the galactic
winds in ellipticals of mass M_G>1e9 M_Sun is most likely negligible.
