Water and energy are both important resources for regional
economies, and they are inextricably and reciprocally linked. Energy
producers require a lot of water. Crude oil production, for
example, consumes 1.1 m3 water/GJ [1]. Numerous studies have
investigated the water footprint of energy production (WFEP),
which is the water directly and indirectly required for energy
production. The WFEP of bioenergy is especially of interest because
of the large amount of water consumed per unit of energy produced
