Some aspects of European climate policy

Being heavily energy dependent, it is not much of a surprise that Europe pays special attention to reducing the use of fossil fuels. Each one of the ten new member states is characterized by relatively low per capita energy consumption and relatively low energy efficiency, and the share of renewables in their energy mix tends to be low, too. The paper examines the problem, when the policy measures create a decrease in environmental capital instead of an increase. In this case it hardly seems justified to talk about environmental protection. The authors describe a case of a rapeseed oil mill which would not be of too much interest on its own but given that almost all similar plants went bankrupt, there are some important lessons to learn from its survival. The enterprise the authors examined aimed at establishing a micro-regional network. They completed a brown-field development to establish a small plant on the premises of a former large agricultural cooperative. By partnering with the former employees and suppliers of the sometime cooperative, they enjoyed some benefits which all the other green-field businesses focusing on fuel production could not. The project improved food security, energy security and population retention as well.

Kihívások és lehetőségek a hazai megújuló energiaszektorban (Challenges and possibilities in the Hungarian renewable sector)

A megújuló energiatermelés szerepének erősödését figyelhetjük meg az utóbbi években, évtizedekben. A zöldenergiák iránti igényt három fő motivátorcsoporttal lehet indokolni: ellátásbiztonság növelése, környezetvédelem és gazdaságélénkítés. Ezek a szempontok együttesen a fenntartható fejlődést szolgálják, és egyre inkább előtérbe kerülnek mind az EU, mind pedig hazánk szintjén. Magyarország 2010 végén az EU által előírt, 2020-ra elérendő 13%-os megújuló energiaarányt meghaladó, 14,65%-os vállalást tett a Nemzeti Cselekvési Tervben, ezzel is kifejezve elköteleződését a zöldenergiák ösztönzése felé. A jelenlegi kapacitások több mint megkétszerezését igénylő cél a hazai megújuló energiaszektor számára érdemi lehetőségeket jelent, de ezek megvalósításához szükség lenne az ígért új zöldenergia-támogatási rendszer, mielőbbi életbe lépésére. ____ The role of the renewable energy generation is getting even bigger and bigger in the last years, decades. The demand for the green energy has three main motivators: energy security, protecting the environment and fostering innovation. These goals serve the conception of sustainable development, and their function is increasingly highlighted in the EU and in Hungary as well. The EU has prescribed Hungary to reach a 13% share of renewable energy sources in 2020, but in the Hungarian national renewable action plan we have aimed to top the EU request, and to reach a 14,65% in the renewable proportion. This shows that our country is committed to inspire the renewables. In order to reach this goal, Hungary has to more than double its green power plant capacity, which means great possibilities in the sector; but at the same time means challenges as well, because the new renewable promoting system needs to come into force as soon as possible.

Aplicação do exame da proporcionalidade diante da implantação de empreendimentos eólicos em áreas de preservação permanente

The setting up of wind power enterprises at Permanent Preservation Areas reflects the obvious conflict and necessary convergence between free market and energy security on the one hand, and the promotion of environmental quality on the other. From the perspective of energy sustainability, and in order to achieve development (in its complex meaning, which converges economic, social, environmental and cultural aspects), the harmonization between free market and an ecologically sustainable environment is required. This work aims to identify the link between the protection system of the Permanent Preservation Areas and the current constitutional order, by analyzing the implementation of wind power enterprises in these protected zones focusing on the proportionality aspects. A legal and purposeful research was developed, from a theoretical method, followed by collecting and analyzing both primary and secondary data. From these data, the law, the legal literature and judicial decisions were cross-examined, under the light of the Constitution and guided by the theory of proportionality and related development imperatives. In this context, the present study identified the link between the principles of the economic order, environment and energy law, finding their basis under the Federal Constitution and development. By reproducing this interrelationship and by means of post-crisis institutional reforms, the guiding objectives of the Brazilian electric sector began to corroborate the precepts of development, although issues regarding its sustainability still persist. The appraisal of proportionality indicates that the Permanent Preservation Areas protection system is insufficient to materialize the right to a healthy quality of life upon the implementation of wind projects at Permanent Preservation Areas, albeit seeking the harmonization between free market and environmental protection.

The European Union Foreign Policy in the Caucasus and Central Asia: The Limitations of the Opening towards the East

This article intends to study the evolution of the European Union foreign policy in the Southern Caucasus and Central Area throughout the Post-Cold War era. The aim is to analyze Brussels’ fundamental interests and limitations in the area, the strategies it has implemented in the last few years, and the extent to which the EU has been able to undermine the regional hegemons’ traditional supremacy. As will be highlighted, the Community’s chronic weaknesses, the local determination to preserve sovereignty and an increasing international geopolitical competition undermine any European aspiration to become a pre-eminent actor at the heart of the Eurasian continent in the near future.

El Cambio Climático en la Estrategia Global de Seguridad de la Unión Europea

El cambio climático es uno de los mayores desafíos de la actualidad. La UE ha abordado el tema de forma claramente insuficiente desde el punto de vista teórico, con unos planteamientos demasiado inmovilistas y hasta conformistas con su propia acción. Pero, al mismo tiempo, ha sido uno de los primeros y principales actores internacionales en actuar y posicionarse claramente en la lucha contra el cambio climático. La Estrategia Global de Seguridad de la UE no aborda adecuadamente ni el cambio climático como prioridad fundamental ni algunas de sus implicaciones en las políticas de los Estados Miembros de la UE.

La Seguridad Energética y la Estrategia Global de Seguridad de la Unión Europea

El presente artículo plantea una definición ampliada del concepto de seguridad energética, yendo más allá del concepto clásico establecido por la Agencia Internacional de la Energía, incorporando cuestiones relativas a la eficiencia energética, la aceptabilidad del modelo energético y los retos que impone el cambio climático, pero sin perder de perspectiva las exigencias y las dinámicas competitivas económicas globales. Sobre la base de este concepto ampliado, se examina la evolución de la seguridad energética en el marco de la Unión Europea, con una atención particular a cómo se concibe la seguridad energética en la Estrategia Global de Seguridad de 2016.

Wind turbine indirect ice detection and operational analysis

Wind energy is one of the most promising and fast growing sector of energy production. Wind is ecologically friendly and relatively cheap energy resource available for development in practically all corners of the world (where only the wind blows). Today wind power gained broad development in the Scandinavian countries. Three important challenges concerning sustainable development, i.e. energy security, climate change and energy access make a compelling case for large-scale utilization of wind energy. In Finland, according to the climate and energy strategy, accepted in 2008, the total consumption of electricity generated by means of wind farms by 2020, should reach 6 - 7% of total consumption in the country [1]. The main challenges associated with wind energy production are harsh operational conditions that often accompany the turbine operation in the climatic conditions of the north and poor accessibility for maintenance and service. One of the major problems that require a solution is the icing of turbine structures. Icing reduces the performance of wind turbines, which in the conditions of a long cold period, can significantly affect the reliability of power supply. In order to predict and control power performance, the process of ice accretion has to be carefully tracked. There are two ways to detect icing – directly or indirectly. The first way applies to the special ice detection instruments. The second one is using indirect characteristics of turbine performance. One of such indirect methods for ice detection and power loss estimation has been proposed and used in this paper. The results were compared to the results directly gained from the ice sensors. The data used was measured in Muukko wind farm, southeast Finland during a project 'Wind power in cold climate and complex terrain'. The project was carried out in 9/2013 - 8/2015 with the partners Lappeenranta university of technology, Alstom renovables España S.L., TuuliMuukko, and TuuliSaimaa.

Os Estados Unidos da América e a Revolução do Shale

Ao longo dos últimos anos, tem-se verificado grandes mudanças no mercado energético global, sendo os Estados Unidos da América um dos grandes protagonistas. A presente investigação tem como principal objetivo compreender e clarificar o conceito de independência energética/auto-suficiência energética e averiguar a possibilidade e o alcance deste propósito por parte dos Estados Unidos da América, desde a Revolução do Shale. Ao longo desta investigação haverá oportunidade de estudar as políticas energéticas assumidas durante aproximadamente os últimos 40 anos, obter informações sobre a segurança energética dos Estados Unidos, bem como formas de exploração energética americana, política para exportação de energia e impactos geopolíticos. Facilmente se observa ao longo deste trabalho que a auto-suficência não pode ser vista numa perspetiva de criação de condições para o isolacionismo americano mas sim numa perspetiva de instrumentalização e proteção dos seus aliados.

Heterogeneously catalyzed hydrothermal processing of C5-C6 sugars

Biomass has been long exploited as an anthropogenic energy source; however, the 21st century challenges of energy security and climate change are driving resurgence in its utilization both as a renewable alternative to fossil fuels and as a sustainable carbon feedstock for chemicals production. Deconstruction of cellulose and hemicellulose carbohydrate polymers into their constituent C5 and C6 sugars, and subsequent heterogeneously catalyzed transformations, offer the promise of unlocking diverse oxygenates such as furfural, 5-hydroxymethylfurfural, xylitol, sorbitol, mannitol, and gluconic acid as biorefinery platform chemicals. Here, we review recent advances in the design and development of catalysts and processes for C5-C6 sugar reforming into chemical intermediates and products, and highlight the challenges of aqueous phase operation and catalyst evaluation, in addition to process considerations such as solvent and reactor selection.

Las empresas energéticas y la gran estrategia estadounidense hacia Irak : una reflexión sobre el rol de Exxon Mobil y Chevron como grupos económicos y de presión (2001- 2011)

La monografía pretende explicar el rol desempeñado por Exxon Mobil y Chevron en la formulación de la Gran Estrategia del gobierno Bush hacia Irak. Especialmente, se sostiene que las dos compañías multinacionales mencionadas lograron que la intervención militar en Irak, fuera pensada como un objetivo fundamental de la política energética del gobierno Bush. Para lograr este objetivo, Chevron y Exxon aprovecharon principalmente su posición en la economía nacional estadounidense. De hecho, lograron celebrar contratos a largo plazo para la extracción del crudo y de gas en Irak. Fundamentándose en un análisis documental, estas compañías son analizadas como grupos de presión empresarial y grupos económicos, cuyos beneficios derivados de la invasión en Irak pueden encontrarse incluso durante el gobierno Obama.

La seguridad energética de Estados Unidos a inicios del siglo XXI: ¿securitización o politización del acceso a recursos energéticos?

Tradicionalmente, la consolidación de la seguridad energética en Estados Unidos se ha mostrado como un asunto de seguridad nacional. En especial, la escasez de recursos energéticos ha sido vista como un problema existencial que requiere de medidas de emergencia en el marco de un proceso de securitización. Sin embargo, esta investigación surgiere que el tema ha sido mayoritariamente politizado a inicios del siglo XXI. Quizá este proceso de securitización tan solo fue implícitamente planteado con ocasión de la invasión a Irak en 2003, en la medida en que dicha intervención pudo haberse inspirado por la necesidad de derrocar a un régimen que había impedido el acceso estadounidense a recursos petroleros iraquíes. En este orden de ideas, la investigación analiza las políticas de seguridad energética de los gobiernos de George W. Bush y Barack H. Obama con el propósito de entender el grado en el que estas estuvieron vinculadas a sus respectivas agendas de seguridad nacional.

Evaluation, energy optimization, and spectrum analysis of an artificial noise technique to improve CWSN security

This paper presents the security evaluation, energy consumption optimization, and spectrum scarcity analysis of artificial noise techniques to increase physical-layer security in Cognitive Wireless Sensor Networks (CWSNs). These techniques introduce noise into the spectrum in order to hide real information. Nevertheless, they directly affect two important parameters in Cognitive Wireless Sensor Networks (CWSNs), energy consumption and spectrum utilization. Both are affected because the number of packets transmitted by the network and the active period of the nodes increase. Security evaluation demonstrates that these techniques are effective against eavesdropper attacks, but also optimization allows for the implementation of these approaches in low-resource networks such as Cognitive Wireless Sensor Networks. In this work, the scenario is formally modeled and the optimization according to the simulation results and the impact analysis over the frequency spectrum are presented.

Towards a new multilateral energy architecture? Security Policy Brief No. 39, October 2012

From climate change over peak oil to the geopolitical scramble for the Arctic, there are ample signs that a global energy crisis is unfolding. The sheer scale and urgency of this looming crisis calls for international coordination. Yet, even a cursory look at the existing international energy institutions leads to a sobering conclusion: the global energy governance architecture is weak, fragmented and incomplete. This policy brief discusses both the flaws in the multilateral energy architecture and some emerging ideas to strengthen it, such as the proposal for a Sustainable Energy Trade Agreement and the new American disclosure rules for the extractive sector.
