Turkish Public Preferences for Energy
(Elsevier Science, 2018) Ediger, Volkan S.; Kirkil, Gökhan; Çelebi, Emre; Ucal, Meltem Şengün; Kentmen-Cin, Çiğdem
Public concern over energy supplies prices sustainability and efficiency has emerged as a major issue around the world. Yet most of what we know regarding public opinion on energy comes from North America and Europe. This paper presents the results from the 2016 Turkish Public Preferences for Energy Survey which included 1204 respondents and examined Turkish residents' household energy consumption energy policy preferences and environmental concerns. The main findings were that Turkish citizens consider natural gas and electricity highly expensive view dependence on imported energy as Turkey's most pressing energy challenge and recognize the problem of climate change. This lends public support for wind and solar power but at the same time energy issues and the environment policies of political parties do not affect voting choices and political preferences.
Analysis of the Liberalization of the Turkish Natural Gas Market
(Kadir Has Üniversitesi, 2023) UĞUR, ETHEM; Volkan Ediger, Şevket
Natural gas is used as a bridge fuel during the ongoing transition from fossil fuels to renewables because it produces less carbon emissions than oil and coal. In addition, countries, which are aiming to become more carbon neutral, are replacing coal with natural gas. These reasons have led the natural gas industry to grow and the gas business has gained an international dimension. In order to keep up with these developments, countries liberalize their gas markets by opening them to competition. The two important pillars of liberalization are third-party access to the physical infrastructure and the demolition of monopolies in the market. The European Union (EU) has implemented a series of reforms to be able to fully liberalize its internal gas markets. Turkey, the fourth largest gas-consuming country in Europe, has also made a series of reforms in order to harmonize with Europe during the EU accession process since 2001. However, Turkey’s goals to open its internal gas market to competition have only been partially achieved. The main purpose of this study is to analyze the performance of the Turkish natural gas market and to determine to what extent gas market reforms have been successful. The results of a detailed examination of the market and the survey carried out among the major market players have shown that the Turkish natural gas market should be improved in transparency, competitiveness, and cost-based pricing.

Energy Management in Organized Industrial Zones: Promoting the Green Energy Transition in Turkish Manufacturing Industry
(IEEE Computer Society, 2024) Ediger,V.Ş.; Küçüker,M.A.; Berk,I.; Inan,A.; Üçtuǧ,F.G.; 0
Organized Industrial Zones (OIZ), which gained legal status by Law 4562 of 2000, played a significant role in Turkish industrialization policies, particularly in improving Small and Medium-sized Enterprises (SMEs). The energy management (EM) within OIZs is essential for Türkiye's green transition and 2053 net-zero pathway. Following the publication of a directive on OIZ's electricity market activities in 2006, enterprises can purchase electricity directly from OIZ management. Moreover, the Energy Efficiency Law No. 5627 of 2007 required OIZs to establish an energy management unit (EMU) to serve the participants with less than 1000 tons of oil equivalent (toe) energy consumption. EMUs provide OIZ management with a unique opportunity to enhance sustainable energy transition by increasing renewable energy production and improving the energy efficiency of participating enterprises. The primary goal of this research is to evaluate the effectiveness of energy management units in OIZs in encouraging energy efficiency and green energy transition in the Turkish manufacturing industry. As a case study, we examine EM in the Adana Haci Sabanci Organized Industrial Zone (Adana OIZ), which ranks third among OIZs regarding electricity consumption. We analyze data on electricity infrastructures, roof-top PVs, invoice settlements/offsets, energy efficiency investments, and GHG emissions between 2017 and 2023. Our preliminary findings suggest that EMU in the Adana OIZ makes a very important contribution to the green transition of industrial establishments and that regulatory changes over the last decades have had positive effects. The share of renewable energy in the total energy mix increased from 1.6% to 21.4% over six years, and there has been a noteworthy enhancement in energy efficiency, reaching 27% in 22 companies evaluated. The main policy implication of our findings is that the role of regulatory bodies and efficient energy management in OIZs will be critical in achieving Türkiye's net zero target of 2053. © 2024 IEEE.

The Effect of Energy Geopolitics on International Climate Change Initiatives
(Uluslararası İlişkiler Konseyi Derneği, 2017) Ediger, Volkan S.
In this article in general the relationship between international climate change initiatives and energy geopolitics was analyzed and in particular the developments in energy geopolitics were investigated with a historical point of view by dividing the years between 1965 and 2014 into periods of geopolitical intensity and geopolitical stability based on long-term periodic variations in oil prices. More specifically the reasons why international initiatives such as the Kyoto Protocol regarded as an important agreement for imposing commitments in climate change mitigation have not been sufficiently successful were investigated. Regarding the Kyoto Protocol the failure stemmed from three main reasons. The first and the most important reason was the intensification of geopolitical tensions on a global scale. The second reason was the differences among states in terms of their energy needs and possession of indigenous energy sources. The last reason was the ambiguity regarding the role of the state and the market at the implementation level. The author links the general failure in the efforts to tackle climate change to the developments in energy geopolitics and argues that the competition periods in energy geopolitics as observed during the oil crises decrease the chances of success for international initiatives on climate change.
Natural Gas Exploitation in the Eastern Mediterranean: a Holistic Approach
(Kadir Has University Center for Energy and Sustainable Development, 2023) Ediger, Volkan; Elfeky, Rahma; Karampalis, Dimitrios; Mengi, Hazal; Tan, Sadık Erkan; Bowlus, John Vincent; Friedrich Naumann Foundation for Freedom’s Türkiye Office
Discoveries of significant natural gas reserves in the Eastern Mediterranean since 2010 have elevated the region’s geopolitical importance from being strictly based on security to one also based on energy and has thus drawn in outside powers that are eager to address their energy-supply security needs. The energy crises triggered first by the supply chain disruptions in 2021 and then the Russia-Ukraine War in 2022 have elevated the region’s importance as a potential energy supplier and transit hub for Europe. This report takes a holistic approach to critically assess the activities carried out in the Eastern Mediterranean region in the fields of exploration, discovery, development, production, and export of natural gas, and the delimitation of exclusive economic zones (EEZs), as well as the effects that these activities have on the economies, policies, and strategies of Eastern Mediterranean countries at the interstate, regional and global levels. Previous studies have generally evaluated the activities related to natural gas in the Eastern Mediterranean from narrow perspectives and only a very small number have dealt with all these elements considered together and with analysis of cause-and-effect relationships on a regional or global scale. The authors deploy a systemic approach that is similar to the petroleum system concept, which evaluates hydrocarbon generation, migration, accumulation, and entrapment in an entire petroleum system on the basis of its essential elements (sources, reservoirs, seals, and overburden rocks) and processes (trap formations and generation-migration-accumulation) as well as the preservation time and, most importantly, the critical moments when events are significant enough to affect the whole system. Likewise, this report uses qualitative and quantitative media analysis of six newspapers – two from Egypt, two from Greece, and two from Turkey from the first discovery of gas by Israel in 1999 to 2023 – to determine the critical moments that have brought what the authors term the Eastern Mediterranean gas exploitation system (EMGES) to a crossroads, where either conflict and confrontation or stability and cooperation will prevail. No one can predict when this system will be overwhelmed by the essential elements (the ten Eastern Mediterranean states), the essential processes (activities related to gas exploitation and delimitation of EEZs), and the critical moments (major conflict periods). This is rendered even more uncertain by a rapidly shifting geopolitical context that is being shaped by the energy transition from fossil fuels to clean energy sources as well as the transition from a unipolar to a multipolar world. Given how interconnected all these factors are, only a holistic approach can help illustrate how the EMGES has reached this crossroads. For stability and cooperation to prevail in EMGES, two conditions must be met. First, countries must recognize that they are directly interconnected and depend on one another and a common vision that balances the economic and strategic interests of each country to forge development and sustainability. Second, a robust cooperative structural framework must be developed that does not exclude any individual country and involves external powers, most notably the EU and the United States.
Renewable Energy in Turkey: a Cleaner, Self- Sufficient Alternative To Coal
(Kadir Has Üniversitesi, 2019) Karagöz, Gözde Nur; Ediger, Volkan S.
The world is in the midst of a transformative energy transition, moving to renewable energy sources from fossil fuels. The biggest reasons for this transition are global climate change and resource scarcity, both of which are caused by the use of fossil fuels. Among fossil fuels, coal has the highest emissions and causes more significant damage to people and the environment. Despite its negative effects, coal has a large share of the world's energy mix. However, many countries are moving away from coal and switch to renewable energy sources. Turkey is not one of those countries, as the energy system is still heavily dependent on fossil fuels and coal specifically. Turkey is planning on new coal-fired power plants in addition to existing ones and is generally supporting the coal industry. In addition to the environmental harm to Turkey – and the world – of its coal usage, most of the coal that Turkey burns is imported, thus contributing to the country's trade deficit. In order to limit the negative effects of coal use, Turkey needs to utilize its high renewable energy potential. This study reviews the current situation of coal and renewable energy sources in Turkey. It aims to look at current coal and renewable energy policies and compare them. According to this analysis, it will then offer suggestions for how Turkey can phase out coal and switch to renewable energies.

An Assessment of Mining Efficiency in Turkish Lignite Industry
(Elsevier Science, 2015) Ediger, Volkan S.; Berk, Istemi; Ersoy, Mucella
This article focuses on the mining activities of Turkish Coal Enterprises (TKI) the major lignite supplier in Turkey. First we analyzed the lignite production and overburden removal activities of TKI from a historical perspective and then employed the Principle Component Analysis to build a mining efficiency index of TKI and investigated its historical development since the establishment of the company. We found that labor productivity and operational structure have been the most important factors positively affecting the index. The current article makes two important contributions: (1) by using the most comprehensive data set available on TKI for the first time and (2) by developing a Mining Efficiency Index (MEI) which can be used to analyze productivity in lignite mining activities in different countries.

Geopolitics and Gas-Transit Security Through Pipelines
(Springer International Publishing, 2020) Ediger, Volkan S.; Bowlus, John V.; Aydın, Mustafa
Hydrocarbons are valuable only if they can be transited from where they are produced to where they are consumed. Despite the enduring importance of transit to the global energy system, the topic did not begin to be extensively analyzed until contentious relations between Russia and Ukraine disrupted natural gas flows to Europe in 2006. This chapter examines the geopolitics and security of transiting gas through pipelines by exploring the connection between geography, global energy strategies, and natural gas markets. Gas has grown in recent years as a percentage of global energy consumption and is helping the world transition to a cleaner energy regime. At the same time, it is intensifying the contest for and control of gas-transit routes. Russia, the world’s second-largest producer, has built new pipelines to Europe since 2006 in order to diversify its flow from relying on Ukraine, while the USA, the world’s largest gas producer, is increasingly exporting liquefied natural gas (LNG) through sea routes mostly controlled by the US navy. We argue that geostrategic calculations will more profoundly affect gas transit in the future and that countries that rely solely on market or commercial factors for their gas-transit security will become increasingly vulnerable to geopolitical volatility.

A Historical Assessment of Turkey's Natural Gas Import Vulnerability
(Pergamon-Elsevier Science Ltd, 2018) Berk, Istemi; Ediger, Volkan S.; Ediger, Volkan S.
This article aims at evaluating the historical determinants and implications of Turkey's natural gas import dependency. We implement principle component analysis (PCA) methodology to construct a natural gas import vulnerability index (NGIVI) for the period between 1986 and 2014 using five factors: (1) the share of natural gas in primary energy consumption (2) the share of natural gas in primary energy imports (3) the non-diversification of natural gas import sources (4) the share of LNG in total natural gas imports and (5) natural gas import prices. Results reveal that the first two factors have always dominated the NGIVI while the others were consequential but different times. Turkey's NOM increased until 2008 when it peaked and remained relatively flat since then indicating neither an improvement nor a worsening in its vulnerability. We also compared the NGIVI with the oil import vulnerability index (OIVI) of Turkey constructed in 2011 by the authors. Although there has been a remarkable decline in the OIVI since the mid-1980s the NGIVI has remained high until the present day. This result could be attributed to Turkey's different historical experience in importing oil and natural gas. (C) 2018 Elsevier Ltd. All rights reserved.

Lignite Resources of Turkey: Geology Reserves and Exploration History
(Elsevier Science, 2014) Ediger, Volkan S.; Berk, Istemi; Kosebalaban, Ayhan
This article aims to emphasize the importance of lignite which is the mostly used domestic energy source in the Turkish energy mix by briefly overviewing its geology reserves and exploration. Lignites are distributed in mostly continental sedimentary basins of Tertiary age all over the country. The lignite-bearing basins display the characteristics of different geological settings of which grabens and half-grabens are the most common ones especially in western Anatolia. The geological and chemical characteristics of Turkish lignites do not only create some important problems during mining and coal preparation but also make them unfavorable for consumption. However since they are the most valuable energy resource of the country they should benefit the economy in the most efficient and environmentally friendly way. Moreover two most important conclusions of this study are as follows: firstly reserve estimation practices in the country should definitely be revised to provide a more realistic evaluation of the country's lignite potential for developing medium- and long-term energy strategies and policies for decision- and policy-makers. Secondly exploration and development activities should be coordinated by a single institution most likely a government institution as has been the case for some 50 years. (C) 2014 Elsevier B.V.
