: The concept of energy hubs has grown in prominence as a part of future energy systems, driven by the spread of Distributed Energy Resources (DERs) and the inception of the smart grid. This paper systematically reviews 200 articles about energy hubs, published from 2007 to 2017, and summarizes them based on their modeling approach, planning and operation, economic and environmental considerations, and energy hub applications. The common applications of energy hubs are considered, such as distributed energy resources, the consideration of Plug-in Hybrid Electric Vehicles (PHEVs), and the hydrogen economy. This paper examines modeling approaches towards energy hubs, including storage and its network models; it mentions some of the optimization strategies used to tackle the efficient operation and control of energy hubs. The novelty of this work lies in the classification of research papers related to energy hubs, the development of a generic framework for modeling these multiple energy flow carriers with storage and network considerations, and the provision of solution techniques in line with energy hub optimization.

Abstract This paper presents a new architecture of energy hubs for animal farms considering the availability of energy resources in the farm such as biogas, solar, etc. It is proposed to combine three energy carriers: biogas, heat and electricity into an aggregate system to improve the energy efficiency of the farm. The problem is to determine the optimal allocation of distributed energy resources such as biogas generators, photovoltaics, battery and electric grid, etc. with the objective function is minimizing the total cost of energy hubs, i. e. life cycle cost while subjected to the constraint of heat, electricity and gas demands. The uncertainty of renewable energy is taken into account not only with the daily and monthly variation of the resource but the forecasting error as well. In addition, the sensitivity of the life cycle cost with respect to the price of electricity is analysed in different scenarios. The problem is examined in a case study of a typical pig farm in Northern Vietnam in both cases: with and without the ability to sell the surplus electricity to the grid. The simulation result shows the effectiveness of the proposed energy hub compared to other approaches.

The article examines the energy policy of Turkey in connection with the country’s desire to become an international energy hub concentrating supplies from neighboring energy resources exporting countries, due to its unique geographical location. Its key position between Asia and Europe facilitates the passage through its territory of transport routes, allowing diversification of exports and imports for neighboring countries. Turkish economic policy, conducted in recent decades, allowed the country to make a leap in its development. To maintain the existing growth rates of the economy, it is necessary to have sufficient energy consumption. The dependence of the country on external energy sources leads to a multi-vector geopolitics, conducted by the country’s government. Turkey is surrounded by countries with which there are economic and geopolitical disagreements. Orientation on Russia with its large and diverse energy resources and a capacious domestic market will support the existing growth rates of the economy, occupy the unemployed population and stabilize energy supplies. Energy diplomacy has become an important factor in ensuring the energy security of both Turkey and its partners. Energy security is influenced by such factors as disruptions in energy supply and price volatility in the global energy market. The development of energy is currently taking place in the mainstream of energy programs, the main components of which are economics, politics, scientific and technical progress, social and environmental problems. The uniqueness of EGP between the zones of energy production and consumption increased the importance of the country as an transiter of energy, that controling the Black Sea straits and having ports on the Black and Mediterranean Seas.

The article discusses the future of mobility in the light of energy resources. Fossil fuel will not be available for a long time - not to mention its growing environmental and political conflicts. In analysing the potential of biofuel it is argued that the high demands of modern mobility can hardly be fulfilled in the future. Furthermore, the change into using biofuel will probably lead to increasing conflicts between the fuel market and the food market, as well as to conflicts with regional agricultural networks in the third world. Petrol imperialism might be replaced by bio imperialism. Therefore, mobility on a solar base pursues a double strategy of raising efficiency on the one hand and strongly reducing mobility itself on the other.

In the article the global crisis of 2008-2009 is considered as superposition of a few regional crises that occurred simultaneously but for different reasons. However, they have something in common: developed countries tend to maintain a strong level of social security without increasing the real production output. On the one hand, this policy has resulted in trade deficit and partial destruction of market mechanisms. On the other hand, it has clashed with the desire of several oil and gas exporting countries to receive an exclusive price for their energy resources.

Factors and Resources: Identity, Difference, or Opposition?

The article tries to distinguish theoretical notions of factors and resources in economics and to consider paired connections between factors (labor, capital, and land) and resources (information, energy, matter). The author traces the logic of transition from scarcity of direct reproducible material goods via limitations of non-reproducible indirect goods (energy resources) to limiting of individuals creative opportunities as a factor of survival of humanity.
