Özet:

The need and consumption of energy in the world is increasing rapidly because of factors such as population growth and technological developments. In recent years, the increase in per capita energy consumption has reached remarkable levels, the purpose of reducing foreign dependency in energy production and being a determinant actor in global economic competition have increased the importance of energy production. For this reason, countries that have energy resources have moved to an economically different position than other countries. However, the reasons such as today's environmental problems, the exhaustion of fossil resources or the lack of fossil resources have increased the interest in renewable energy sources. In the EU membership process, evaluating the performances of Turkey and EU countries in context of renewable energy will contribute to the literature and studies. The aim of this study was to evaluate the efficiency of Turkey and EU countries in terms of renewable energy and economic growth relationship. As a result of the literature review conducted within the scope of the study, 5 variables related to renewable energy indicators were determined. CO2 Emission, Percentage of Renewable Electricity Output in Total Electric Output, Labor are input variables; GDP per capita and the Percentage of Renewable Energy in Total Energy Supply are output variables. In this study, changes in performances of EU countries and Turkey during the period 2008-2015 are evaluated with the help of aforementioned economic and renewable energy indicators. The Malmquist Total Factor Productivity (TFP) index was used to evaluate the development of productivity over time. Since the Malmquist Index is an index based on Data Envelopment Analysis (DEA), a cluster analysis has been performed and similar countries have been grouped in order to ensure homogeneity among decision-making units. Since the Malmquist Index is an index based on DEA, a cluster analysis has been performed and similar countries have been grouped in order to ensure homogeneity among decision-making units. As a result of the study, when the countries have been ranked according to TFP average values in the period 2008-2015, it is seen that Luxembourg ranks first with a significant difference from other countries. Belgium, Turkey, Bulgaria, Slovenia, Croatia, Cyprus follow Luxembourg respectively and Turkey also appears to be one of the successful countries according to the average value TFPD.
