Final Energy Consumption

The European Union’s policies regarding the energy security impose to the European countries to take urgent measures because of the global energy demand which is growing rapidly. The ambitious target approved by the renewable energy directive is that 20 % of the final energy consumption has to be provided by renewable sources by 2020. The technological transfer from west to east Europe encourages the eastern countries with a high agricultural potential to develop political, economical, and social strategies to replace the fossil resources with the renewable materials. The main goal of the European countries is to promote the clean energy technologies. Thus, the share of renewable resources such as wind, solar, biomass, geothermal, biogas, etc. has to be increases with 24 % of the final energy consumption compared to the overall EU target of 20 %. The current work emphasize the technological state and perspectives of the biogas production of the Romanian country in comparison with the leader country in Europe, Germany.

The paper provides a comparative analysis of economic growth in Estonia, Latvia and Lithuania and discusses differences in development of the main sectors during the period 2000–2016. Based on detailed analysis of energy sector development, the driving factors influencing changes in primary energy consumption in each country and in the Baltic region are discovered. Increase of renewable energy sources (RES) consumption in the Baltic region over this period by 73.6% is emphasized. The paper presents valuable insights from analysis of trends in final energy consumption by sectors of the national economies, branches of the manufacturing sector, and by energy carriers. Long-term relationships between economic growth and final energy consumption are established. An econometric model was applied to predict final energy demand in the Baltic States for the 2020 horizon. It is emphasized that growing activities in the manufacturing and transport sectors will cause increase of final energy demand in all three countries. Based on detailed analysis of greenhouse gas (GHG) emissions trends some positive shifts are shown and the necessity of new policies in the transport sector and agriculture is identified. Changes of emission intensity indicators are examined and a potential for decoupling of carbon dioxide (CO2) emissions from economic growth in Estonia is indicated.

Final Energy Consumption

The need for decarbonization raises several questions. How can renewable energy supply for the industrial sector be realized in the long term? Furthermore, how must the existing energy system be transformed to achieve the ambitious climate targets in place? In Austria, the share of renewable energy supplying industrial energy demand currently accounts for only 45% of final energy consumption. This clearly shows that a conversion of industrial energy systems is necessary. Different ambitious perspectives for a renewable energy supply for the Austrian industrial sector are calculated for three defined scenarios (base, efficiency, transition) in this paper. In addition, corresponding requirements for the energy infrastructures are discussed. The scenario results show a range of industrial final energy consumption from 78 TWh (efficiency) to 105 TWh (transition) through decarbonizing the industrial energy supply (cf. 87 TWh in 2019). Decarbonization requires an increasing shift towards electrical energy, especially in the transition scenario, whereas in the base and efficiency scenarios, biogenic fuels play an important role. Comprehensive decarbonization and the associated substitution of energy carriers in industry pose significant challenges for the existing energy infrastructure, its expansion, and optimization.

Abstract One of the most important goals of the European Union is to provide citizens of the Member States security and stability in fuel and electricity sectors. The United Nations has defined 17 goals and 169 actions to achieve sustainable development of the world. The goals were to improve the quality of life, reduce the level of poverty, inequalities in the world and sustainable development in terms of climate and environmental protection. The article presents an analysis of the implementation of one of the assumed goals, i.e., sustainable development in the field of Affordable and clean Energy in the European Union. This goal is to ensure that every citizen has access to stable, sustainable, and modern energy at an affordable price. Among others, indicators such as energy import dependency, energy productivity, share of renewable energy in gross final energy consumption, final energy consumption in households per capita were analysed. The authors analysed the trends of the above-mentioned indicators in the European Union, with particular emphasis on Poland. In order to be able to predict how the analysed phenomena will develop until 2030, the authors built forecasts. For this purpose, among others, ARIMA models were used. The authors created several dozen models, from among which model with the smallest ex post errors and the lowest value of information criteria were selected. The models allowed to determine the degree of achievement of the set goals. They also allowed the designation of scenarios for the potential development of the analysed indicators.

Abstract One of the most serious challenges facing the world, including the European Union and Poland, is the climate crisis and environmental pollution. The article presents an analysis of the implementation of sustainable development goals in the field of Affordable and clean Energy in Poland. The Sustainable Development Goals have replaced the Millennium Goals and enable their continuation. They were defined at the United Nations Conference in 2012. 17 goals and 169 actions were set. Sustainable Development Goals are a set of activities, the implementation of which is to lead to the development of sustainable development in the environmental, social and economic terms. Achieving the goals will be possible among others through changes in the field of climate, education, poverty or the natural environment. The study analyses, inter alia, such indicators related to the discussed objectives like energy import dependency by products, energy productivity, share of renewable energy in gross final energy consumption by sector, final energy consumption in households per capita were analysed. This made it possible to indicate the level of achievement of the set goals, as well as to determine the possibility of achieving the goals set by 2030. The authors also presented the results of the generated for the analysed indicators forecasts. The presented results were obtained with the use of mathematical models, which were finally selected by the authors after the validation process. The time horizon of the forecasts was adjusted to the requirements of sustainable development goals. Countermeasures that can be taken to accelerate the deadline for achieving the targets were also outlined.

Austrian district heating (DH) has experienced a fast increasing trend for the last 30 years (with the exception of the period 2010-2014), resulting in a triplication of delivered heat; in the year 2018, with about 2400 networks and 20 TWh supply, DH covered 6.4% of the final energy consumption (1122.5 PJ). Worth to underline is also that this growth of Austrian district heating has been about twice faster than the one of the energy demand in the same period. Currently, district heating provides about 26% of the Austrian households with the energy requested for space heating and domestic hot water preparation.

Abstract Megacities are mainly located in developing countries and face challenges in building infrastructures to ensure modern and clean energy access to citizens while coping with lifestyle changes. This paper assesses the renewables impact on energy transition for megacities (supply and all demand sectors) using the Greater Cairo megacity as case study. The MARKAL-EFOM System (TIMES) model is applied to the Greater Cairo region to investigate how energy supply and demand will evolve till 2050, and what are the impacts in terms of final energy consumption, GHG emissions, as well as share of renewable energy sources consumption in total final energy consumption considering two different emissions mitigation caps, namely 50% and 80%. Compared to the business as usual scenario, the final energy consumption decreases of 46 PJ and 57 PJ respectively in the scenarios with the CO2 cap of 50% and 80%. Besides, the TIMES-Greater Cairo shows that the fossil free energy options are limited and thus, in order to meet the emission cap, it is necessary to deploy more energy efficient technologies than in the scenarios without the cap. Transport is the sector with the higher CO2 emissions contribution and the optimization results show that it may lower the environmental impact of 28% by 2050 with the sole deployment of more efficient technologies.

Hydropower (HP) in Europe is playing an increasingly important role. Its share in final energy consumption varies from country to country, which is associated with different challenges for each of them. This article presents the challenges of HP development in three countries with a diversified domestic share, i.e., Albania (100% share in 2019), Slovenia (25.7%) and Estonia (0.3%). Particular attention was paid to issues of rational management of water resources in conjunction with the objectives of nature protection and European energy policy. As a result of the analysis, the following challenges in the development of HP were identified: the need to modernize the current HP network, conflicts related to the implementation of HP projects in naturally valuable areas, dependence on external electricity supply due to adverse environmental conditions, problems with the diversification of energy sources and lack of cooperation between environments representing different interests. The countries described have different local specificities; therefore, the challenges in the development of HP are different in each of them. The key to solving them is especially mutual cooperation between various environments, integration of energy markets and diversification of used energy sources, with an indication of renewable energy sources (RES). This will enable harmonious development of each country. Furthermore, it cannot be clearly determined whether the assumed objectives of EU energy policy will be achieved. Achieving these goals is possible because the share of RES in final energy consumption in the countries described is growing.

This study investigates the impact of economic growth on three main development sectors, household final consumption expenditure, and trade openness towards the growth of final energy consumption in Indonesia using annual data for the period 1972-2016. We applied autoregressive distributed lag (ARDL) procedures which consist of stationarity test, cointegration test, as well as estimation the short-term and long-term relationships. The cointegration test revealed existence cointegration<br />relationship among the variables in the model. In the short-term and long-term model, our results indicated that the growth of value-added in agriculture sector and industry sector, household final consumption expenditures, and trade openness in the short-term and long-term have a significant effect toward final energy consumption in Indonesia, while the growth of value-added in the service sector only given a short-term effect toward final energy consumption in Indonesia. Based on these<br />results, it can be concluded that sustainable economic development in Indonesia needs to be accompanied by the development of new and renewable energy in order to fulfil domestic energy supply which is predicted to continue to increase rapidly in the future.<br />Keyword : final energi consumption, economic development, household final consumption expenditure, trade openness, autoregressive distributed lag modeling<br />JEL Classification : D1, E21, F14, O13, Q43.

The Death of Industrial Civilization explains how the contemporary ecological crisis within industrial society is caused by the values inherent in unlimited economic growth and competitive materialism. It demonstrates the central role and importance of electricity, and what policy makers need to do in order to ensure that current and future systems remain reliable even as they are transformed by the rise of clean energy technologies. The novel COVID19 pandemic has created an unprecedented global health and economic crisis. The result of such a scenario is that energy demand contracts by 6%, the largest in 70 years in percentage terms and the largest ever in absolute terms. The impact of Covid19 on energy demand in 2020 would be more than seven times larger than the impact of the 2008 financial crisis on global energy demand and this is what the Olduvai theory is defined by e=energy production/population. It states that the life expectancy of Industrial Civilization is less than or equal to 100 years.

Polluting Emissions

Covering the energy demands under environmental protection and satisfying economic and social restrictions, together with decreasing polluting emissions, are impetuous necessities, considering that over half of the pollutant emissions released in the environment are the effect of the processes of electricity and heat production from the classic thermoelectric powerplant. Increasing energy efficiency and intensifying the use of alternative resources are key objectives of global policy. In this context, a range of new energy technologies has been developed, based on alternative energy conversion systems, which have recently been used more and more often for the simultaneous production of electricity and heat. An intensification of the use of combined energy production correlated with the tendency towards the use of clean energy resources can be helpful in achieving the global objectives of increasing fuel diversity and ensuring energy demand. The chapter aims at describing the fuel cell technology, in particular those of the SOFC type, used in the CHP for stationary applications.
