“…Source: Author's calculations Figure 2 shows the changes in the mean energy efficiencies of the EU-28 countries for the period of 2005-2017 expressed in terms of their total factor productivity index values. The empirical findings were consistent with the studies by Vlahinic-Dizdarevic and Segota (2012), Sözen and Alp (2013), Borozan (2018) and Chang (2020). Accordingly, as the energy efficiency in the countries with the index values of 1 was unchanged in the period, those countries with the index values higher than 1 and lower than 1, respectively, increased and decreased.…”

Energy efficiency is one of the most effective methods of fighting climate change, achieving supply security and succeeding in resource effectiveness. For this reason, European Union (EU) countries follow mutual energy policies related to energy efficiency, with directives of the European Commission. This study used the Malmquist Total Factor Productivity Index to determine the extent to which 28 EU countries used energy efficiently in the output (GDP) production process in the period of 2005-2017. The results of the analysis indicated that the energy efficiency of EU-28 countries increased by an average of 1.1% for the period under review, and that the increases in efficiency varied between countries. Also, energy efficiency decreased only in Poland throughout the studied period. Although the Union has a common energy policy, it is thought that there are two main reasons for the energy efficiency differences in the member countries of the Union. The first of these is the energy structures of the countries, while the second is the energy policies of the countries that are shaped by their own internal dynamics.

Summary Traditional gasification parameters, such as cold gas efficiency, hot gas efficiency, or thermal efficiency, only evaluate the heat energy utilisation efficiency of gasifiers and do not take into account the gasification processes expending electricity and other types of energies. Therefore, the energy conversion efficiency cannot be assessed using these parameters. The calculation process on the energy conversion efficiency of underground coal gasification (UCG) is the basis for obtaining quantitative data of carbon emission reduction and establishing the carbon trading methodology of UCG. Moreover, the energy conversion efficiency both for surface coal gasification and UCG is a key research topic because it directly affects the economic and environmental benefits of gasification projects. This study proposed that two parameters, the integrated gasification efficiency (hcom) and the hot gas integrated gasification efficiency ( hnormalcnormalonormalm′), should be included into the coal gasification parameters and used to evaluate the energy conversion efficiency of coal gasification. In addition, the calculation methods of these two parameters for both surface gasification and UCG were established. Using the method, hcom and hnormalcnormalonormalm′, of the UCG and Texaco gasification under the same scale was compared and that of various UCG processes was calculated. The results proved the necessity and reasonability of the two parameters and suggested that a certain amount of CO2 was favourable to improve hcom and hnormalcnormalonormalm′ of UCG. However, a certain amount of pure O2 can improve hcom of UCG without direct influences on hnormalcnormalonormalm′. Under the condition of each process, to maximise hcom and hnormalcnormalonormalm′, there must be an optimal steam (CO2) to O2 rate. Copyright © 2015 John Wiley & Sons, Ltd.

“…Data envelopment analysis is a linear programming based technique which aims to measure the relative performance of decision units in times when it is hard to make a comparison between inputs and outputs which have been measured by a number of different measures or which have different measurement units. "Decision Units" are management or economic organizations whose performances will be compared (Zhou et al, 2008;Sozen and Alp, 2013). The method was developed firstly by Charnes Cooper and Rhodes.…”
