Research background: Energy policy is closely linked to economic development. Therefore, its optimization is an important issue especially in the contemporary European environmental conditions.  EU regulations enforce a reduction of carbon dioxide emissions and the abandonment of non-renewable energy resources. Instead, they promote renewable energy sources. In this way, new legal and environmental circumstances are becoming the main reason for the transformation of energy balances, which is a real economic and technological challenge. This transformation requires a strategic and effective approach, especially in those countries which until now have used mainly hard coal in the energy sector. Purpose of the article: According to above justification, the main purpose of the article is to identify the strategies for the transformation of energy balances that were implemented in the years 1990–2017 by chosen European countries and Turkey. Methods: The study period covers the years 1990–2017, and the subject of the research at first applies to all European countries, and then to 7 countries selected due to their high share of bituminous coal in energy balance in the first year of the analysis, treated as the initial point of transformation (1990). As a result of this selection, 6 EU members and Turkey with the largest share of coal in energy production in the year 1990 are examined. Particularly, an analysis of the trends in their energy balances in the years 1990–2017 is conducted. The research uses data on non-renewable energy consumption and renewable energy resources and the total energy consumption. The research methodology includes: analysis of the structure and dynamics, evaluation of trends and comparative analysis and presentation of development strategies. At the end of the article, a comparative analysis is carried out, the economic consequences of identified changes are assessed, and recommendations are formulated aimed at optimizing the structure of the energy balance in the future. Findings & Value added: Generally, there are four theoretical and empirical patterns of transformation strategies of energy balances with dominant coal consumption: 1) using other non-renewable energy resources; 2) replacing non-renewable energy resources with renewable ones; 3) using nuclear energy instead of coal; 4) increasing coal consumption as available and efficient energy resource. It was found that the examined countries implement mainly the strategy in which the decreasing share of coal is made up for by an increasing share of gas. Additionally, we can observe an increase in the share of nuclear energy in France, the Czech Republic and the United Kingdom. In Spain and Germany, despite the use of nuclear power plants for the production of energy, the share of nuclear energy in the energy balances has systematically decreased in time. In all analyzed countries, we can also observe an increasing share of renewable sources in energy balances, however, this growth is very slow.

A study of the energy efficiency of the fuel and energy complex of the regions has a great attention. For an integrated introduction of trends and patterns in the energy sector, approaches we use based on the analysis of the fuel and energy balance (FEB). The function of FEB is to show the availability and use of energy resources in a certain territory and determination of indices of energy efficiency. The article presents an approach to the formation of fuel and energy balances based on the available statistical information.

This paper on food energy production and consumption illustrates to what extent agriculture in the Netherlands is dependent on fossil fuel. It can be seen from tabulated data on energy balance in agricultural systems that energy input for secondary production (e.g. meat, milk and eggs) exceeds energy output by approx. 60 X 1012 kcal/yr (70.1 vs. 10.2 X 1012 kcal/yr); this large difference, however, is mainly due to use of fodder (43 X 1012 kcal/yr) rather than use of fossil fuel. Possible ways to diminish the fossil energy input of the modern farm are discussed. (Abstract retrieved from CAB Abstracts by CABI’s permission)

The fuel and energy complex is the basis for the development of the national economy. Computer simulation of the development proces­ses of the fuel and energy complex is of great theoretical and practical importance as an effective method for studying large and complex systems. The purpose of this study is to develop a methodological approach for conducting energy-economic analysis, identifying factors affecting the energy efficiency of the economy. Research methods are economic and mathematical modeling, system and statistical analysis, balance and indicative methods. The article presents the results of the analysis of the fuel and energy complex of Russia and Mongolia based on a combined fuel and energy balance. The conclusion is made about the need to improve the energy efficiency of the countries’ economies. The use of energy-saving technologies and equipment will reduce the cost of production and consumption of fuel and energy resources, reduce losses at all stages of their life cycle, while the planned indicators of socio-economic development can be achieved with less energy and financial costs, which will positively affect the economy and improve the quality of life of the population.

Энергетический баланс и структура потребления энергии являются важными показателями для создания энергетической стратегии Китайской Народной Республики. В данной статье кратко изложены основные направления энергетической стратегии Китая на будущие десять лет, которые представлены в 13-й энергетической пятилетке и Стратегии по изменению в производстве и потреблении энергетических ресурсов (2016-2030 гг.)». Проанализирована текущая структура энергопотребления и баланс энергоресурсов, суммированы результаты 13-го пятилетнего энергетического плана. Представлены обоснования для разработки 14-го пятилетнего энергетического плана. Автор сделал вывод, что в основном 13-я энергетическая пятилетка выполнила задачи в области регулирования энергетической структуры и развитии чистой и низкоуглеродной энергии, но в области природного газа не может достигнуть целевых показателей. The energy balance and energy structure are important indicators for planning a country's energy strategy. This article summarizes the main directions of the country's energy strategy for the next ten years, based on those proposed in the 13th Energy Five-Year Plan, and the Strategy for Changes in the Production and Consumption of Energy Resources (2016–2030). The current structure of energy consumption and the balance of energy resources are analyzed, and the results of the “13th five-year energy plan” are summarized. Based on this, a gap with the energy strategic direction is presented in order to provide justification for the development of the “14th Five-Year Energy Plan”. The author concludes that basically the “13th energy five-year period” fulfilled the tasks in the field of regulation of the energy structure and the development of clean and low-carbon energy, but in the field of natural gas can not reach the target.

Nowadays, in the context of climate change, efficient energy management and increasing the share of renewable energy sources in the energy mix are helping to reduce greenhouse gases. In this research, we present the energy system and its management and the possibilities of its development through the example of an ecovillage. The basic goal of such a community is to be economically, socially, and ecologically sustainable, so the study of energy system of an ecovillage is especially justified. As the goal of this community is sustainability, potential technological and efficiency barriers to the use of renewable energy sources will also become visible. Our sample area is Visnyeszéplak ecovillage, where we examined the energy production and consumption habits and possibilities of the community with the help of interviews, literature, and map databases. By examining the spatial structure of the settlement, we examined the spatial structure of energy management. We formulated development proposals that can make the community’s energy management system more efficient.
