The French Bioenergetics Group (GFB) is an association under the 1901 law whose objective is to support the development of scientific research in the field of bioenergetics and to federate all the laboratories working in this field. The main activity of the GFB is the organization of a biannual congress.

Bioenergetics focuses on the mechanisms of energy conversion by living organisms, whether they are bacteria, unicellular eukaryotes (diatoms, amoebae, yeasts, etc.), plants or animals. This energy can be light, electrical, chemical, osmotic, mechanical or thermal.
