Energy Balances

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.

The main purpose of this study is to investigate the causal relationship among renewable energy, nuclear energy consumption, economic growth, and CO2 emissions for selected OECD countries over the period 1980 to 2013. All variables are found to be cointgrated.Results of Granger causality show long-run relationship from GDP, renewable energy consumption and nuclear energy consumption to CO2 emissions, from CO2 emissions, GDP, to renewable energy consumption, from emissions, GDP to renewable energy, and from CO2 emissions GDP and nuclear energy consumption.In short run, results show that there exists bidirectional causality between GDP and CO2 emissions, and unidirectional causality running from renewable energy consumption to GDP. Also unidirectional causality running from renewable energy consumption to CO2 emissions without feedback but no causality running from nuclear energy consumption to CO2 emissions was found. This evidence suggests that renewable energy can help to mitigate CO2 emissions, but so far, nuclear energy consumption has not reached a level where it can CO2 emissions.

Abstract The article presents the analysis of the potential of using biomass and coal co-firing in the Polish electro energetic system and shows the benefits resulting from an increase of biomass amount in electricity production in one of the largest Polish power stations. The paper discusses the most often used technologies for biomass co-firing and the potential of using biomass in electricity production in Poland. It also emphasises the fact that biomass co-firing allows a reduction of greenhouse gases emissions to the atmosphere and helps decrease consumption of energy resources. The article also emphasises the economic meaning of increasing the share of renewable energy resources in energy balance, including biomass, due to costs related to greenhouse gases emissions charges. Finally, conclusions from using biomass and coal co-firing in electricity production are presented

The World

Europe is transforming its energy balance and increasing the use of local renewable energy sources. Russia's economy depends on the export of fossil (non-renewable) energy resources. About half of the country's energy resources are exported, primarily to European countries. A change in the fuel and energy balance of European countries, as the main consumer of Russian energy resources, will affect the Russian economy. Therefore, Russia urgently needs to know the state of alternative energy in Europe. The purpose of this article is to assess the growth rate of the share of innovative alternative energy sources in the energy balance of Germany and Denmark, as leading countries. The background for the implementation of energy policy in the field of alternative energy is different. First of all, these are countries with developed economies. They need a reliable, uninterrupted supply of energy sources. The Danish government was the first among European countries to evaluate the potential of alternative energy and began to develop it. Denmark is the first country in Europe to use wind energy to generate electricity. In 1991, the first offshore wind energy plant in Europe appeared in Denmark. Germany started the construction of wind power parks only in 2008. Nevertheless, today Germany, along with China and the United States, is among the top three world leaders in terms of wind power capacity, and also has become one of the world leaders in terms of the total installed capacity of solar panels. In absolute terms, characterizing the development of alternative energy, Germany is the world leader, in relative terms - Denmark. Germanys economy is many times larger than Denmarks. Therefore, Germany cannot rebuild the fuel structure of its economy as fast as Denmark. The Danish leadership has set ambitious goals for the development of alternative energy. In 2050, 100% of the energy supplied to end consumers will be generated from renewable sources. Germany cannot rebuild its economy with this fast pace. In Germany in 2050, the share of renewable energy in final energy consumption will be 60%. Germany, unlike Denmark, initially relied not on the development of alternative energy, but on the development of nuclear energy. However, through consistent energy policies, it has become a world leader in alternative energy use. When Germany began to implement energy policy, it already had a prototype - Denmark. But then, as the study showed, the country chose its own path. And then Germany and Denmark developed alternative energy in different ways. Nowadays the international cooperation has a great importance. Germany and Denmark collaborate in regional and transregional projects in terms of renewable energy sources. North Sea Wind Power Hub is a successful example of their work together. The experience of Germany and Denmark has shown that alternative energy development programs do not exist by themselves. The alternative energy development program is only part of several other related programs. Among them are programs on the rejection of the use of nuclear energy (in relation to Germany), measures to increase the energy efficiency of economies, construction of infrastructure, changes in the organizational structure of energy, etc. Nowadays, many countries in the world pursue an energy policy in the field of renewable energy. In 2009, Russia also committed to increase the share of alternative energy sources to 4.5% by 2020. In the implementation of this policy, it is necessary to take into account the experience of Western countries. The difficulties faced by countries in the new energy sector do not allow us to talk about a decrease in their dependence on energy imports.

The paper presents the results of the comparative analysis of operation modes of an autonomous hybrid power complex with/without the energy store. We offere the technique which defines the power characteristics of the main components of a hybrid power complex: the consumers of the electric power, wind power and photo-electric installations (the last ones have been constructed). The paper establishes that, in order to compensate the seasonal fluctuations of power in autonomous power systems with renewable energy resources, the accumulative devices are required, with a capacity of tens of MWh including devices that are capable to provide energy storage with duration about half a year. This allows abandoning the storage devices for smoothing the seasonal fluctuations in the energy balance.The analysis of operation modes of energy stores has shown that for a stock and delivery of energy on time intervals, lasting several hours, the accumulative devices with rather high values of charging and digit power aren't required. It allows using the lead-acid rechargeable batteries of the deep category for smoothing the daily peaks of surplus and a capacity shortage. Moreover, the analysis of operation modes of energy stores as a part of the hybrid complexes has demonstrated that in charging/digit currents of the energy store the low-frequency and high-frequency pulsations of big amplitude caused by changes of size of output power of the renewable power installations and loading are inevitable. If low-frequency pulsations (the period of tens of minutes) can partially be damped due to the restriction of size of the maximum charging current of rechargeable batteries, then it is essentially impossible to eliminate high-frequency pulsations (the period of tens of seconds) in the power systems with the only store of energy. The paper finds out that the combined energy store having characteristics of the accumulator in the modes of receiving and delivery of power on daily time intervals, and at the same time having properties of the supercondenser in the modes of reception and return of impulses of power on second intervals of time is best suited to requirements of the autonomous power complexes with renewable energy resources.
