Future Biomass Energy Supply: The Consumptive Water Use Perspective

• There are major expectations that bioenergy will supply large amounts of CO2 neutral energy for the future. A large-scale expansion of energy crop production would lead to a large increase in evapotranspiration appropriation for human uses, potentially as large as the present evapotranspiration from global cropland. In some countries this could lead to further enhancement of an already stressed water situation. However, there are also countries where such impacts are less likely to occur. Studies that assess bioenergy potentials need to consider restrictions from competing demand for water resources. Studies of the future state of water availability and use need to include the possibility of new high demands for water from a growing bioenergy sector.
