Geopolitics and gas-transit security through pipelines
Authors:
Publisher and Date:(Springer International Publishing, 2020)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 ...

An integrated review and analysis of multi-energy transition from fossil fuels to renewables
Authors:
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 ...

Greasing the wheels: the Berlin-Baghdad railway and Ottoman oil, 1888?1907
Authors:
Publisher and Date:(Routledge Journals, Taylor & Francis Ltd, 2020)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 ...

Perception, petroleum, and power: Mythmaking in oil-scarce Turkey and Jordan
Authors:
Publisher and Date:(Elsevier, 2020)Oil has been a cardinal driver of economic growth and national development in the twentieth and twenty-first centuries. States that produce oil in globally exportable quantities tend to be more powerful than those that do not. Oil-scarce states in the Middle East that neighbor oil-rich states and rely on them for imports create myths to explain their relatively unfortunate geology. This study illustrates and analyzes the myths that people in Turkey and Jordan have created to explain why they lack ...

Introduction: Energy economics finance and geostrategy
Authors:
Publisher and Date:(Springer International Publishing, 2018)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 ...

Geostrategic challenges in the oil and gas sectors
Authors:
Publisher and Date:(Springer International Publishing, 2018)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 ...

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