Abstract

The demand for energy is growing day by day, and at the same time economy is an important issue to be handled with this growing. In this respect, many countries are undertaking significant roles to decline their energy intensities (energy supply or consumption per unit of economic output) whereas this variable may be single factor for the international comparisons. This study including many factors with the energy intensity measures energy efficiency of countries and positions Turkey among them. Data envelopment analysis (DEA) using multiple input and outputs is a non-parametric technique for the efficiency evaluation of a set of decision making units (DMUs). In the analyzes, the OECD and BRICS (Brazil, Russia, India, Democratic People of China and South Africa) countries were used for 2009–2013 period. For this period, the Malmquist productivity index (MPI) method was also used to observe the dynamic progress of DEA analyzes. The efficiency analysis of OECD (Organization for Economic Cooperation and Development) and BRICS (Brazil, Russia, India, China and South Africa) countries is conducted from 2009 to 2013. According to the results, the efficient countries are members of the OECD group and MPI of an average country worsens 1.4% over the period. As a member of OECD, Turkey is not efficient country with the score of 0.048 and Turkey’s MPI also worsens 4.5% for the whole period. Because the energy imports have become a threat to Turkey’s economy in recent years, the findings will be helpful guidance in seeing its relative position and in taking precautions. As a result of this study, it is given some suggestions to increase the efficiency of Turkey in the model.
