In one embodiment, a sustainable hydroponic growing system comprises at least one hydroponic growing unit, an algae growing unit configured to produce an algae biomass, a biofuel system configured to process the algae biomass to produce a bioethanol fuel and a solid oxide fuel cell configured to use the bioethanol fuel as at least one source of fuel to produce electrical power for use by the at least one hydroponic growing unit. In one embodiment, the solid oxide fuel cell is further configured to produce steam that serves as a water source for the at least one hydroponic growing unit and/or the algae growing unit.
