Water Footprint of bioenergy from Wheat Crop in Iran

All energy scenarios show that the energy supply approach is shifting to renewable energy, in particular energy from biofuels. On the other hand, in the context of this type of energy, water which is a limiting factor in the discussion of agricultural products, arises. In this research, using the water footprint index, the amount of water consumed for the production of each energy unit was calculated from wheat biomass. In this regard, six provinces of the country with the highest production value were selected. The purpose of this study was to determine the most desirable province for producing bioenergy from wheat biomass from the perspective of the water footprint index. The results of this study showed that Golestan, Kermanshah, Ardebil, Khuzestan, Fars and Khorasan Razavi provinces devoted 25.1, 33, 35.5, 39.4, 43.9 and 83.7 cubic meter of water per GJ, respectively and this values showed the priority to produce bioenergy from wheat biomass. In other words, from the perspective of the water footprint, the productivity of bioenergy production in Golestan province is more than other provinces. Therefore, this situation has created an advantage for the use of wheat biomass in the province.
