Reviewing DEA applications in empirical energy efficiency studies

Energy is indispensable in the creation of value added, and energy efficiency is critical not only for the existence and growth of any entity, but also for achieving the sustainable development goals in general. Hence, improving energy efficiency and consequently environmental efficiency has become one of the most important energy, economic and ecological policy challenges which requires a comparable longitudinal measurement and monitoring of the same as a major prerequisite. To raise awareness and knowledge of researchers, practitioners and policy authorities on how to measure energy efficiency, which is a part of environmental efficiency, this paper introduces the basic data envelopment analysis (DEA) models and explains their main assumptions, benefits and limitations. It also briefly reviews the literature covering DEA applications related to energy efficiency for which considerable growth has been recorded in the past two decades. The findings indicate that recent applications of DEA in the field of energy efficiency obviously go beyond pure energy efficiency towards its explicit integration with various environmental concerns. This fact will mark future trends of DEA applications in energy efficiency and energy economics in general.
