The project so far revealed that energy efficiency measures belong to the top activities selected by enterprises to react to these new challenges. The main purpose of the study is to determine the role of KIBS in the currently changing German energy sector. The general context of KIBS is being presented through a literature research, including the KIBS framework in the sectors of energy efficiency, energy audit, energy management and related areas. As being top actual, this specific topic was sofar not researched yet, the article covers the identified gap in literature.
