The present invention is directed to a process for the production of ethanol and energy. The process includes the steps of fermenting a corn mash in an aqueous medium to produce a beer. Next, the beer is distilled to produce ethanol and a whole stillage. The whole stillage is anaerobically digested to produce a biogas and a residue. The biogas is combusted to produce electricity and steam. The electricity and steam are used during the fermentation and distillation process. The residue may further be separated into a liquid fertilizer and top soil residue.
