The concept of an autarky has a long history and meaning related to its negation and unpopularity. In liberal schools of economics, autarky is usually considered from the perspectives of economic trade protectionism, closed economies, and threats to welfare. Nevertheless, the concept of autarky has gained a new meaning, understood as the local utilization of renewable energy resources from the perspective of their inter- and intragenerational distribution. Local action is shaped by the global perspective. This research consists of three steps. First, a model of energy autarky has been offered based on the system theory. The model shows the variety of the structures and features of energy systems offered in today’s debates on energy autarky. Second, the key postulates of sustainable development have been presented to define an autarkical sustainable energy system. Finally, the concept of bioenergy villages in Germany has been presented to illustrate the approach to energy autarky. The research shows that the concept of autarky and single solutions, such as the use of renewable resources, are not themselves a success from the perspective of sustainable development; this misunderstanding is well illustrated by the evolution of the German concept of bioenergy villages into smart villages.

Abstract This article is part of a first year doctoral research regarding the current state of knowledge in environmental sustainability, energy economics and their impact on European enterprises. As the current changes and modifications of the German energy economics system are observed by people all around the globe, the current paper analyzes what has been said until now in the scientific literature on character of the new strategy for energy consumption and production in Germany and its impact on environmental and social sustainability. With the help of two questionnaire-based surveys conducted in 2013 and 2014 through the German DIHK1, German enterprises were surveyed in order to: identify potential differences and similarities between the two periods, identify the effects of the energy transition on companies’ profitability, and analyze these effects and compare the results in terms of potential trend developments. The research findings confirmed that changes in the energy system affect not only the environmental sustainability only, but also the economy, in some cases even independent of the stage in which the changing system of the economy presently is.

Solar energy systems are becoming potential option for numerous applications. It has been shown that the application of solar energy system is strongly dependent on criteria’s used in their evaluation. Single criteria evaluation of solar energy systems has shown its deficiency due to limited possibility to compare them with other potential options. In particular, present economic system is based on the econometric analysis with priority given to the optimum obtained by the economically justified optimization function. For this reason, it has become needed to introduce multi-criteria evaluation procedure in the assessment of solar energy system and its comparison with other potential options. This paper presents evaluation of the solar photovoltaic system and its comparison with other renewable energy system options for stand-alone application. In this evaluation following energy systems will be taking into a consideration: grid electric energy supply, wind energy system, gas turbine with cogeneration, small hydro energy system and solar photo-voltaic energy system. In the evaluation of these systems the multi-criteria evaluation procedure is used. The multi-criteria evaluation procedure will comprise a following criteria’s: economic, environmental, technological and social indicators. Each of indicators will be based on the sub-criteria which are defined in the paper. The sustainability index as the agglomeration function indicators will be used in the determination of the rating among the options under consideration. Special emphasize in evaluation is given to to the conditional priority of indicators leading to the investigation of the effect of the indicator priority to the finale rating among options.

AbstractOn the path to an energy transition away from fossil fuels to sustainable sources, the European Union is for the moment keeping pace with the objectives of the Strategic Energy Technology-Plan. For this trend to continue after 2020, scientific breakthroughs must be achieved. One main objective is to produce solar fuels from solar energy and water in direct processes to accomplish the efficient storage of solar energy in a chemical form. This is a grand scientific challenge. One important approach to achieve this goal is Artificial Photosynthesis. The European Energy Research Alliance has launched the Joint Programme “Advanced Materials & Processes for Energy Applications” (AMPEA) to foster the role of basic science in Future Emerging Technologies. European researchers in artificial photosynthesis recently met at an AMPEA organized workshop to define common research strategies and milestones for the future. Through this work artificial photosynthesis became the first energy research sub-field to be organised into what is designated “an Application” within AMPEA. The ambition is to drive and accelerate solar fuels research into a powerful European field – in a shorter time and with a broader scope than possible for individual or national initiatives. Within AMPEA the Application Artificial Photosynthesis is inclusive and intended to bring together all European scientists in relevant fields. The goal is to set up a thorough and systematic programme of directed research, which by 2020 will have advanced to a point where commercially viable artificial photosynthetic devices will be under development in partnership with industry.

The Impact

The article considers the preconditions for sustainable development of the energy sector from the standpoint of political and economic basis of energy transitions, actualizes and reveals the scientific problem of the impact of socio-technical transitions, in particular energy, on economic sustainability. It is determined that the task of assessing the efficiency of the energy system as a set of criteria for achieving a compromise of interests, stability and reliability of energy markets is best solved by assessing energy sustainability. Problems and ways to intensify the use of energy policy levers to promote sustainable energy transitions have been identified. It is determined that with the help of sustainable energy transitions the state is able to overcome its own inefficiency of energy conversion and consumption and to demonstrate the phenomenon of decoupling (economic growth without significant growth of energy consumption). Energy policies and strategies as means of energy transition management are considered: creation of preconditions for their occurrence; acceleration / deceleration, support of current transittions; minimization of negative external factors and social factors of vulnerability to changes in socio-technical regimes; maintaining an optimal energy balance. A deeper understanding of the process of energy transition management, vulnerability of energy systems under their influence has been achieved. Three key factors of energy transition management in order to strengthen the level of energy sustainability and ensure sustainable development of the economy: the course (flow) of transitions, the vulnerability of the economic system under their influence and the level of sustainability of energy transitions. Effective management of such transitions with the help of these factors can be a guarantee of sustainable development not only of the energy sector but also of the economy as a whole and create the conditions for its transition to a sustainable and circular type of development. The management of energy transitions in the energy sector of Ukraine is analyzed on the example of diversification of electricity supply through the operation of small solar power plants in private households.

Energy is the prerequisite and most universal measure of all kinds of work by human beings. Everything in this world is the expression of flow of energy in one of its forms. Sustainable resources of energies are those that do not deplete the Earth’s natural resources and are as environmentally benign as possible. These sources are sustainable in that they can be managed to ensure they can be used indefinitely without degrading the environment (Renewable Energy Association, 2009). The energy resources available can be divided into three types. These are primary energy sources (coal, oil, natural gas, uranium) which provide a net supply of energy, secondary energy sources (solar energy, wind energy, hydro energy etc.) which provide no net energy, and supplementary energy sources (geothermal and  tidal) whose net energy yield is zero. Energy is an important input in all sectors of any country’s economy.  The standard of living of any given country can be directly related to per capita energy consumption. Energy crisis is due to the rapid growth of world population and the improved standard of living of human beings. The per capita energy consumption is a measure of the per capita income or it is a measure of the prosperity of the nation.  As the world population is growing at a faster rate, so the conventional sources of energy are depleting on the one hand and its uses are adversely affecting the environment on the other hand. If it will be continued with the same pace, it may be exhausted by the beginning of the next century.  Nuclear energy requires skilled technicians and poses the safety as regards to radioactive waste disposal. Therefore, solar energy and other non-conventional energy sources are the sources; those which are to be utilized in the future. In this paper an attempt has been made to investigate the Potentials of sustainable energy resources in Eritrea with special reference to solar energy. The present study will also explore the intensity of global solar radiation reaching on a horizontal surface over Eritrea. This will be purely done by assessing the degree of solar energy penetration on Eritrea. The paper aims at discussing the cheaper and cleaner use of which is vital to the Eritrean economy and the environment as well.

Currently, the world is confronted with a series of challenges including resource shortage, climate change, environment pollution and energy poverty, which are rooted in the humanity’s deep dependence on and large-scale consumption of fossil energy. To tackle with those challenges is an urgent task for realizing sustainable development. The Global Energy Interconnection (GEI) is a clean energy-dominant, electricity-centered, interconnected and shared modern energy system. It is an important platform for large-scale development, transmission and utilization of clean energy resources at a global level, promoting the global energy transition characterized by cleaning, decarbonization, electrification and networking. The GEI has provided a scientific, novel and systematic solution to implement Agenda 2030 as well as the Paris Agreement. Focusing on the scope of clean transition and sustainable development, this paper has implemented qualitative and quantitative methods based on historic data. The global power demand and supply has been forecasted. Based on global clean energy resources endowments and distribution, a global main clean energy bases layout and generation planning optimization has been proposed. Later in this paper, the global power flow under the GEI scenario and corresponding GEI backbone grid has been explored and proposed. Finally, based on a preliminary investment estimation, the comprehensive benefits of building the GEI have been analyzed.

The article provides an overview of the current state of energy in the world and in Russia, which focuses on the development of renewable energy sources (RES). An analysis is made of the trend in the production and consumption of energy resources, as well as an assessment of the use of renewable energy in Russia. Incentives for the development of renewable energy sources with the characteristics available in the world are determined. Conclusions are drawn about the importance of developing this industry both in Russia and in the Chechen Republic, as one of its regions. An assessment is given of the development of wind and solar energy in Russia. The current power supply structure of the Chechen Republic is considered, where the indicators of maximum electric power, consumed electric power, and also electric power generation of the republic are given. The analysis of the possibility of using wind and solar energy resources, as well as small hydropower of the Chechen Republic. Options for the development and effective use of renewable energy sources are considered, taking into account the fact that the use of energy resources based on modern innovative technologies, the introduction of new promising alternative sources, and the search for ways to stimulate the use of renewable energy sources, where it is supposed to organize and introduce a tariff policy, is one of the main tasks of energy development which give a complete systemic idea of the scale of the problem of transferring the energy system to innovative rails. Some options are proposed for the most expedient development of the energy system of the Chechen Republic, the construction of small pilot plants using renewable energy sources, with the goal of actual (experimental) confirmation of the predicted calculated values, as well as the gradual mass introduction of plants using renewable energy sources in the private sector with the creation of the necessary tariff conditions for use and construction installations on an industrial scale within the framework of energy private or public companies. Priority tasks have been set for the prospective development of the republic’s energy sector by introducing renewable energy sources.
