    Publisher and Date:(Routledge Journals Taylor & Francis Ltd, 2017)
    Since the discovery of oil at Kirkuk in northern Iraq oil has shaped relations between Iraq and Turkey as the former needed markets and export routes to the Mediterranean and the latter reliable sources of supply. This article examines the origins of the Kirkuk-Ceyhan oil pipeline from northern Iraq to the Turkish Mediterranean coast charting the period of Iraqi-Turkish economic rapprochement in the 1960s to the construction of the pipeline in the 1970s. It also seeks to add to our collective ...

  • A Farewell to King Coal: Geopolitics, Energy Security, and the Transition to Oil, 1898–1917 

    Authors:Ediger, Volkan S.; Bowlus, John V.
    Publisher and Date:(Cambridge Univ Press, 2019)
    Interest in energy transitions has accelerated in recent years due to rising concerns about global warming and resource scarcity but the drivers of these phenomena are not well understood. To date scholars have primarily focused on commercial and technological factors highlighting that oil was 'better' than coal - more powerful cheaper cleaner and more practical to use - and that the internal combustion engine made it more advantageous to use in transportation. Yet oil was also a strategic commodity ...

We found that labor productivity and operational structure have been the most important factors ...

  • Energy in Turkey and Russia's Roller-Coaster Relationship 

    Authors:Ediger, Volkan S.; Durmaz, Duygu
    Publisher and Date:(Seta Foundation, 2017)
    Energy relations between Turkey and Russia provide an excellent example of how energy and politics interrelate in countries with a historically up-and-down relationship. Having started in the 1960s the two countries' energy relations gained a new dimension after 1991 with the intensification of pipeline politics. In the 2000s energy relations gained impetus owing to the leadership of Erdogan and Putin and reached an apex with the establishment of a cooperation council in 2010. Since 2011 Turkey's ...

  • Europeanization under Membership Uncertainty: The Cases of Environmental and Energy Policy in Turkey 

    This article examines modalities of rule adoption from the EU's acquis communautaire under conditions of membership uncertainty Drawing upon the case of Turkey we probe into the viability of a policy-type approach (drawing upon Theodor Lowi). Our main contention is that the substantive design of policies (distributive or redistributive qualities) has consequential implications for the form (conflict-free vs. veto player constellations) and outcome (transposition likelihood) of the subsequent ...

  • Flow Structure in a Mixing Layer Developing Over Flat Bed at High Reynolds Numbers 

    Authors:Kirkil, Gökhan
    Publisher and Date:(CRC Press/Balkema, 2016)
    Results of a high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel with a flat bed at a high Reynolds number (ReD = 160000). The influence of Reynolds number on the development of the mixing layer as well as the vertical non-uniformity in the mixing layer structure is discussed. The numerical results show that as Reynolds number increases the mixing layer grows rapidly but also ...

The study discusses the vertical non-uniformity in the mixing layer and provides a quantitative characterization of the growth of the large-scale quasi 2D coherent structures with the distance from the splitter plate. The presence of large-scale roughness elements in the form of an array of ...

  • Forecasting the Coal Production: Hubbert Curve Application on Turkey's Lignite Fields 

    Authors:Berk, Istemi; Ediger, Volkan S.
    Publisher and Date:(Elsevier Science, 2016)
    The dependence on imported energy sources is one of the biggest challenges that Turkey and many other similar countries face in the 21st Century and the gap between production and consumption cannot be decreased without increasing the domestic production. Forecasting of domestic energy production therefore plays a vital role in order to be able to develop sound energy policies towards maintaining sustainable development. However although this question is essential in this respect especially for ...

  • Geopolitics and gas-transit security through pipelines 

    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 ...

  • Geopolitics of oil & gas 

    Authors:Ediger, Volkan S.
    Publisher and Date:(Energy Institute, 2014)

  • Geostrategic challenges in the oil and gas sectors 

    This chapter identifies the major geostrategic challenges that have emerged during the last two decades and assesses their implications for the global oil and gas sectors. The historical development of oil prices shows that there have been two major periods of volatility 1973-1986 and 1998-present each of which was preceded by two relatively stable periods. The two oil price shocks of the 1970s that were triggered by geopolitical events had long-term effects on global politics and economics. Major ...

  • Greasing the wheels: the Berlin-Baghdad railway and Ottoman oil, 1888?1907 

    In the 1880s, Germany cultivated an alliance with the Ottoman Empire that led to a concession to build one of history?s most storied, diplomatically contentious, and financially challenging infrastructure projects: the Berlin-Baghdad Railroad. While Germany had many goals in pursuing the project, oil was the only way to make the railroad economic. Drawing on Ottoman archival sources, this article examines the policies and strategies of Sultan Abd?lhamid II in relation to Germany?s attempt to develop ...

  • An integrated review and analysis of multi-energy transition from fossil fuels to renewables 

    Authors:Ediger, Volkan S.
    Publisher and Date:(Elsevier Science Bv, 2019)
    We are in the midst of a transition from a fossil fuel-dominated energy regime to a more sustainable lower-carbon one in which natural gas is a bridge fuel. Since the 1970s oil crises, however, the forecasts for gas and coal have changed three times. Gas is currently achieving a major position in the world's energy mix but under challenging geopolitical forces; for this reason, different countries will follow different paths for adopting gas. This article uses a ternary diagram to shows that the ...

  • Introduction: Energy economics finance and geostrategy 

    Since countries’ economic independence is based on energy security decisions on energy economy and financing are assessed mainly by geostrategic considerations. Economically optimal decisions are not enough regarding geostrategy. This situation makes it difficult to make decisions in energy markets and it creates considerable controversy. The role of financial markets is to measure the risk of this complex structure or energy projects and price them in financial basis. Understanding behavior of ...
