A new field in human knowledge is nowadays in its way of getting a shape the theory of the bioenergetic evaluation and analysis of fuel and energy. The beginning of this science was set on a congress held in August 1975 in Sweden by a working team on methodlogy og the management of the International Federation of the long-term research institutes. The elaborated joint methodology and the numerous publications that followed from various authors considered single particular matters of the problem, not being subject to a unified scientifically grounded theory and not communicating between themselves. The published results have been of differing objectives and conflicting. Furthermore the general methodology does not provide answers to a number of important questions: when the energy efficiency coefficient assumes maximal values, what the optimum energy consumption levels are, what moderate levels of the yields means, etc.

Key words: energy consumption, grain production, optimum energy levels
