It is becoming more and more likely that molecular outflows are related to the birth of stars in dense molecular gas. The author reviews previous searches for molecular outflows and newly catalogues 144 molecular outflows. The new list is used to test (1) evolutionary status of molecular outflows, and (2) role of molecular outflows in cloud support. An analysis of a complete sample of molecular outflows in L1641 indicates that outflow sources are characterized by significantly greater radiation luminosity than T Tauri stars. Their luminosity excess is explained by the gravitational energy released in the dynamical mass accretion onto the protostellar core. It is therefore suggested that molecular outflows correspond to the main accretion phase of the protostellar evolution. It is shown that outflows can supply turbulence momentum within the cloud free-fall time. It is thus probable that outflows play a role in cloud support.
