Abstract A sample of young stellar objects selected from the IRAS Point Source Catalog (1985) has been surveyed for the presence of high-velocity (C-12)O J = 1-0 emission with the Five College Radio Astronomy Observatory 14-m telescope. Three new molecular outflows have been detected from this survey. The high-velocity emission from these regions is dominated by redshifted material indicative of monopolar outflow. The energy injection rate from all stellar winds within the Taurus cloud complex is compared to the energy dissipation rate due to radiative collisions of clumps. It is uncertain, based on these observations, that the stellar winds can provide the energy necessary to sustain the supersonic turbulent motions which characterize molecular clouds. From a map of (C-13)O J = 1-0 emission of the B18 cloud, the ring of enhanced line widths detected from an earlier study of (C-12)O J = 1-0 emission is confirmed. This ring may be due to the cumulative interaction of accelerated shells driven by stellar winds from several T Tauri stars associated with the cloud.
