Jets and outflows are an integral part of the star formation process. While there are many detailed studies of molecular outflows towards individual star-forming sites, few studies have a molecular cloud-wide view of this phenomenon. The 100 square degree FCRAO CO survey of the Taurus molecular cloud provides an excellent opportunity to undertake an unbiased survey of a large, nearby, molecular cloud complex for molecular outflow activity. Our studies provide information on the extent, energetics and frequency of outflows in this region, which are then used to assess the impact of outflows to the parent molecular cloud. The search identified 17 outflows in the Taurus region, 5 of which were previously unknown. Both 12CO and 13CO data cubes from the Taurus molecular map were used, and dynamical properties of the outflows are derived. Even for previously known outflows, our large-scale maps indicate that many of the outflows are much larger than previously suspected. The majority of the newly discovered outflows have no known associated stellar source, indicating that they may be embedded Class 0 sources.
