Perspectives of energetic exports of Russia in terms of development of the renewable energy sources

The changes in the sphere of the main energy sources in the world and in individual countries were highlighted; the prospects for Russian energy carriers in the global hydrocarbon market were identified. The demand for an energy carrier whose use in Germany is planned to be discontinued (coal) and the demand and competition for natural gas - Russian energy carrier that remains competitive in the conditions of “green” energy were analyzed. The Russian opportunity to save the energy supply market on the background of the new energy order are considered.

The Impact

Greening the economy requires green innovations, and innovations require investments. Most countries of the world are still relying on conventional (fossil-based) sources of energy. The transition toward green or renewable energy sources is an effective and innovative way to meet ever-increasing demand as a result of the rising population. Another reason for innovations in the field of green energy is the need to mitigate climate change and avoid pollution, especially in developing countries. The monitored investments into renewable energy sources are usually public. Therefore, this paper aims to determine whether the selected countries of the world produced renewable energy efficiently, considering the investments made by public financial institutions and installed electricity capacity for renewable energy sources, for the period 2013–2017 (for a deeper analysis, the year 2017 was chosen). For this purpose, the Stochastic Frontier Analysis model in the logarithmic form of the Cobb-Douglas production function is used, which helps to judge the competitiveness of countries based on effectively transforming the inputs into outputs. Results suggest that the effect of the first variable “installed electricity capacity” on electricity generation was highly statistically significant, and the impact of the second variable “public investments” was characterized as statistically insignificant. The monitored countries were divided into 10 groups according to the different range of estimated output-oriented technical efficiency from 0.00 to 1.00. Most countries should increase the renewable electricity generation approximately by 40-49%, given the level of inputs (16 countries of 6th group with estimated output-oriented technical efficiency 0.51-0.60) for the year 2017.

Background: Future sustainable energy industrialization is a green energy source that has a lower circumstantial impact than traditional energy technologies. The advancement of new energy generation is important to expand the share of renewable energy sources. Objective: Worldwide, for the next generation, future energy demand may be fulfilled by using one of the renewable energy sources such as thermo electricity. Methods: The bismuth telluride-based (Bi2Te3-based) nanostructure material in thermo electricity stillhas a major part of applications. It is known as the most prospective TE device manufactured from a research arena towards successful commercialization. Results: The Bi2Te3-based nanostructure material is now on commercialization stages that it has some limitations. In order to find out the future direction of research and development of this material, the material will face a challenging way. Conclusion: The review paper provides an effective approach to overcome the limitation of Bi2Te3-based nanostructure. Moreover, in this review paper, the performance evaluation with existing Bi2Te3-based nanostructure and some other TE materials will be discussed in detail.

The World

The sustainable energy goals are vectors for universal access to affordable, sustainable and modern energy for all. The aim of this work is to study the structure of the world energy supply, including Russia, and the role of energy cooperatives abroad in the past and present on energy supply to agriculture and rural areas, and the possibility of applying their experience in the Russian economy. The authors used observation, abstraction, analysis and synthesis, as well as dialectical and logical methods. Having studied the data of domestic and foreign statistical institutes, the authors came to the conclusion that non-renewable energy sources make up the largest share in the world. In addition to the economical use and efficient conversion of fossil raw materials, the focus is increasingly shifting to the use of renewable energy sources that reduce dependence on oil and gas, in particular in countries that do not have their own reserves, and therefore ensure sustainable energy production. At the same time, the global energy transition to energy resources, which will be available to all, can be carried out with the help of energy cooperatives. In Russia, the capacity of renewable energy facilities is also constantly growing. The peculiarity of the country is the need to transfer energy over long distances with significant wear of transmission networks, a deep monopoly of the market, and, consequently, high tariffs for consumers. One of the ways to solve the problems of affordable energy availability for agriculture, the authors see the creation of energy cooperatives. In the article the approximate model of energy cooperative is offered, their classification is given. The results of the study will help to create competition in the energy market, optimize the budgets of the village and reduce costs in the process of commodity circulation of agricultural products to the final consumer.
