Kazakhstan’s Prime Minister, Karim Massimov, once referred to energy cooperation as the ‘core’ of relations between his country and the European Union (EU). Indeed, there is great mutual interest in this area. Six percent of the EU’s crude oil imports and 16 percent of its uranium imports come from Kazakhstan. And around 80 percent of the latter’s oil exports go towards Europe. For Kazakhstani producers, access to European lucrative and reliable markets is of utmost importance. Over the last several years, the thrust of Kazakhstan’s foreign policy was aimed at increasing the capacity of the Caspian Pipeline Consortium (CPC) that pumps Kazakhstani oil to Europe. Moreover, Kazmunaigaz’s (KMG) – the national oil and gas company – major external investment was in the Romanian oil company Rompetrol.

The oil sector has been the major element of Russian-Chinese energy cooperation. The years 2013–2015 saw a significant increase in the volume of crude oil exported by Russia. In 2015, China became the main importer of Russian oil; Russia became the second largest supplier of oil to the Chinese market, after Saudi Arabia. From Beijing’s perspective, supplies of Russian oil are of strategic importance because the main supply routes are overland routes. Russia, for its part, is interested in boosting its export because of its deteriorating position on the European market, which hitherto has been considered a strategic market.

In energy harvesting communications, users transmit messages using energy harvested from nature. In such systems, transmission policies of the users need to be carefully designed according to the energy arrival profiles. When the energy management policies are optimized, the resulting performance of the system depends only on the energy arrival profiles. In this dissertation, we introduce and analyze the notion of energy cooperation in energy harvesting communications where users can share a portion of their harvested energy with the other users via wireless energy transfer. This energy cooperation enables us to control and optimize the energy arrivals at users to the extent possible. In the classical setting of cooperation, users help each other in the transmission of their data by exploiting the broadcast nature of wireless communications and the resulting overheard information. In contrast to the usual notion of cooperation, which is at the signal level, energy cooperation we introduce here is at the battery energy level. In a multi-user setting, energy may be abundant in one user in which case the loss incurred by transferring it to another user may be less than the gain it yields for the other user. It is this cooperation that we explore in this dissertation for several multi-user scenarios, where energy can be transferred from one user to another through a separate wireless energy transfer unit. We first consider the offline optimal energy management problem for several basic multi-user network structures with energy harvesting transmitters and one-way wireless energy transfer. In energy harvesting transmitters, energy arrivals in time impose energy causality constraints on the transmission policies of the users. In the presence of wireless energy transfer, energy causality constraints take a new form: energy can flow in time from the past to the future for each user, and from one user to the other at each time. This requires a careful joint management of energy flow in two separate dimensions, and different management policies are required depending on how users share the common wireless medium and interact over it. In this context, we analyze several basic multi-user energy harvesting network structures with wireless energy transfer. To capture the main trade-offs and insights that arise due to wireless energy transfer, we focus our attention on simple two- and three-user communication systems, such as the relay channel, multiple access channel and the two-way channel. Next, we focus on the delay minimization problem for networks. We consider a general network topology of energy harvesting and energy cooperating nodes. Each node harvests energy from nature and all nodes may share a portion of their harvested energies with neighboring nodes through energy cooperation. We consider the joint data routing and capacity assignment problem for this setting under fixed data and energy routing topologies. We determine the joint routing of energy and data in a general multi-user scenario with data and energy transfer. Next, we consider the cooperative energy harvesting diamond channel, where the source and two relays harvest energy from nature and the physical layer is modeled as a concatenation of a broadcast and a multiple access channel. Since the broadcast channel is degraded, one of the relays has the message of the other relay. Therefore, the multiple access channel is an extended multiple access channel with common data. We determine the optimum power and rate allocation policies of the users in order to maximize the end-to-end throughput of this system. Finally, we consider the two-user cooperative multiple access channel with energy harvesting users. The users cooperate at the physical layer (data cooperation) by establishing common messages through overheard signals and then cooperatively sending them. For this channel model, we investigate the effect of intermittent data arrivals to the users. We find the optimal offline transmit power and rate allocation policy that maximize the departure region. When the users can further cooperate at the battery level (energy cooperation), we find the jointly optimal offline transmit power and rate allocation policy together with the energy transfer policy that maximize the departure region.

Summary. Expanding EU-China institutional cooperation in the energy sector has been matched by a parallel process of stronger economic ties between European and Chinese companies in the renewable energy (RE) sector (particularly wind and photovoltaics). While the foundation of early EU-China institutional relations was based primarily on trade cooperation, international efforts to mitigate climate change and the common challenge of decreasing energy dependence in a sustainable manner brought a new dimension to their partnership in the energy sector in the mid 90s. Although the role of EU-China energy cooperation has grown tremendously in the context of EU external trade policy and EU strategy to boost its energy independence and international climate policy, the potential of civil society collaboration in this partnership has remained rather unexploited. Based on major civil society initiatives in the RE field that have been developed in recent years, this policy brief argues that civil society dialogue between China and EU could be an important driving force in deepening EU-China cooperation on RE and a bridge towards a more sustainable future.

This paper explains the conflictive and cooperative elements of energy diplomacy between the European Union (EU) and Russia. It argues that interdependence forms the underlying principle of this relationship and creates both sensitivity and vulnerability for the interdependent parties, thus carrying the sperms of both conflict and cooperation. Both sides would be negatively affected by the other side’s noncooperation within the current policy framework and the prevailing mistrust and recurring tensions can be explained by this sensitivity. However, even if both sides’ policies were adjusted, vulnerability interdependence would still prevent them from seriously reducing their energy cooperation. It is necessary then to see how EU and Russian energy diplomacy can converge and how their strategic energy partnership can be cemented.

For many years the European Union has been improving the efficient use of energy resources and yet the demand for energy in the EU continues to increase. When Europe belonged to one of the world’s key energy markets with relatively easy access to energy resources, growing energy needs were not seen as a source of concern. Today, however, as the competition for energy resources is intensifying and the global position of the EU energy market is being challenged by growing economies in the developing countries, above all China and India, the EU needs to adopt bold policies to guarantee the sustainable supply of energy. This report argues the EU needs to develop a fully-fledged external energy policy; i.e. a common, coherent, strategic approach that build bridges between the interests and needs of the EU integrated energy market on the one hand and supplier countries on the other. The EU’s external energy policy has two main objectives. The first one is to ensure a sustainable, stable and cost-effective energy supply. The second is to promote energy market integration and regulatory convergence with neighbouring countries (often but not always this supports the achievement of the first objective). However, in order to improve its effectiveness, the EU’s external energy policy needs to be seen in a broader economic and political context. Any progress in energy cooperation with third countries is contingent upon the EU’s general stance and offer to those countries.

From the Introduction. In order to address the different challenges and opportunities on energy cooperation in the Eastern Mediterranean Region and Levant Basin, EGMONT – The Royal Institute for International Relations of Belgium – together with the Atlantic Council, and supported by H. E. Belgian Minister for Foreign Affairs Didier Reynders, opened an expert dialogue in 2013 in order to look at how the management of the new energy resources could act as a vector of cooperation instead of conflict between the concerned countries. The activities have targeted finding new possibilities for cooperation on political and security challenges, energy infrastructure development, the regulatory and legal framework, environmental concerns, and bilateral and regional structures, in a manner that enhances stability and security in the region, increases European energy security, contributes to rather than hinders a comprehensive Cyprus settlement, and promotes wider regional cooperation.

Back in the autumn of 2014, the deal between Russia and Turkey on the Turkish Stream pipeline was expected to start a period of close energy cooperation between the two countries, potentially able to change the energy game in the region and consolidate political relations in a long-term perspective. One year later, after announcing the project’s size would be reduced by half, Moscow suspended the negotiations in retaliation to the downing of a Russian fighter jet by the Turkish Air Force at the border between Turkey and Syria. This seems to complement growing doubts about Turkish Stream, which already started as a result of Russia’s military involvement in Syria. From an EU perspective, recent developments raise doubts about Turkey’s role in the Union’s energy strategy.

El Grupo Visegrád es un escenario de cooperación multilateral, conformado por Polonia, República Checa, Eslovaquia y Hungría, el cual tiene como objetivo principal contribuir al cumplimiento de los intereses de dichos países, por medio de la financiación de proyectos culturales. El interés de esta monografía consiste en determinar la incidencia de la cooperación cultural en la reafirmación identitaria de cada uno de los miembros del Grupo y, por ende, en la manera como éstos se proyectan dentro de la Unión Europea. Así pues, se identifican los principales hechos históricos que han moldeado los intereses de los países del V4 y que condujeron a la creación de una estructura institucional sólida, que ha servido como plataforma para el accionar de dichos países dentro del bloque europeo. Se utiliza la perspectiva constructivista de Alexander Wendt, la cual permite entender la naturaleza de la cooperación y, su relación con las identidades y los intereses de los Estados.

Las reformas económicas iniciadas por Deng Xiaoping en China y la continuación de estas por sus líderes, han hecho del país asiático una de las mayores fuerzas económicas en el mundo. Sin embargo, su crecimiento económico se ve obstaculizado cuando sus fuentes de recursos energéticos escasean. A partir de esto, China ha iniciado una estrategia en política exterior que combina herramientas de baja política, como lo son la economía y la atracción cultural, para obtener un mayor acceso a hidrocarburos. Uno de los escenarios en donde dicha estrategia se ha hecho más visible es en la relación establecida con Venezuela. En este trabajo se discuten los principales intereses que China tiene en la región, la relación de cooperación energética que entrañan los dos países y las estrategias de corte geoeconómico que la potencia emergente ha implementado para garantizar un aumento en su potencial económico.

The contradictory interests of the EU and Azerbaijan have brought negotiations on their contractual relations to a halt. The EU’s dependence on Azerbaijan’s rich energy resources has weakened the normative dimension of its policy towards Azerbaijan, rendering it incapable of countering rejection of democratic reform by Azerbaijan’s authorities. While the EU’s current approach seems to favour a more pragmatic focus on energy cooperation, this policy brief argues that a combination of normative obligations and pragmatic interests is required − implemented through leverage over Azerbaijan and a better coordination of this policy across the EU member states and institutions.
