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.

Using Data

This study examines the causal relationship between economic growth and renewable energy consumption using data for 28 countries of European Union, taken from Eurostat database for years from 1995 to 2015. In addition, motivated by EU Directive 2009/28/EC, the tendency of the share of renewable energy consumption into the final energy consumption is analysed. Various panel data techniques implemented in EViews are used. The empirical results suggest a positive impact of renewable energy consumption on economic growth, and emphasize bidirectional or unidirectional Granger causalities between the two macroeconomic indicators, for each country in the panel. These results justify the political decisions of EU concerning the necessity of increasing the renewable energy consumption, and prove that this type of energy consumption has a strong positive impact on economic growth. Thus, the inclusion of such policies in future EU and national strategies is further motivated. Finally, by means of linear regression, an increasing trend was found for the ratio between renewable energy consumption and final energy consumption for all but one of the EU countries.

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.

Final Energy Demand

Achieving energy efficiency in buildings is an important factor in developed and as well in developing countries in order to meet its energy demand. Over the past few years, a number of reports have been emerged stating that the buildings sectors are responsible for approximately 31% of global final energy demand. Buildings account for 35% of total final energy consumption in India and building energy consumption is growing about 8% per years. Final energy demand in Indian building sector will grow up-to five times by the end of this century, driven by rapid income and population growth. Hospitals are institutions for the care of people with health problems and are usually functional 24hrs a day, all year around, which demands a lot of energy. Health sector is one of the largest and fastest growing sectors in India. By 2020, it is expected to become a $ 280 billion industry. In India hospitals contribute 23% of total energy consumption and the hospital building growth rate 12–15% in last decade. The World Health Organization estimated that India need 80,000 additional hospital beds every year to meet the demands of India’s population. The aim of this study is to assess the energy demand, energy savings & reduced greenhouse gas emissions by increasing the energy efficiency using advanced retrofitting. Bottom-Up Energy Analysis System (BUENAS) is an end use energy demand projection model for Hospital buildings in India, to normalize the assessment of energy-saving models also going to fill the gap in energy demand reduction by energy system modeling and decomposition analysis. Energy efficiency retrofitting of existing buildings plays a major role in developing country like India in order improve its energy security and minimizing the greenhouse gases. The positive effects of retrofitting of energy efficiency and need the policies and target base proposal for government intention to achieve the potential for energy efficiency are discussed.

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.

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.

The calculative methods, which are adopted in various fields of engineering, are usually a certain kind of theoretical approximation of reality. The deviations from a full consistency of actual conditions and theoretical assumptions occur also in case of building heating. This work presents the selected results of examinations connected with an annual energy consumption CH and annual final energy demand Qk,H for heating and conducted on the group of educational buildings. The presented analysis and its results regard the group including 46 of 50 educational buildings, which form a municipal group of the buildings of this type. The purpose of presented analysis was to examine the influence of possible occurrence and level of differences between the annual energy consumption CH and annual final energy demand Qk,H for heating of examined buildings. The realization of this purpose is the basis for further research and analysis aimed at determining the dominant reasons of mentioned differences, establishing their level and propose a calculative method for reducing the differences between the values "picturing" the thermal needs of educational buildings in actual (energy consumption CH) and theoretical (final energy demand Qk,H) conditions.

Climate change and global warming are related to the demand for energy, energy efficiency, and CO2 emissions. In this research, in order to project the trends in final energy demand, energy intensity, and CO2 emission production in Ecuador during a period between 2000 and 2030, a model has been developed based on the dynamics of the systems supported by Vensim simulation models. The energy matrix of Ecuador has changed in recent years, giving more importance to hydropower. It is conclusive that, if industrialized country policies or trends on the use of renewable energy and energy efficiency were applied, the production of CO2 emissions by 2030 in Ecuador would reach 42,191.4 KTCO2, a value well below the 75,182.6 KTCO2 that would be seen if the current conditions are maintained. In the same way, by 2030, energy intensity would be reduced to 54% compared to the beginning of the simulation period.

This paper examines the energy consumption, supply and resources of some of the countries in the Southern African Development Community (SADC) in 2005, the base year for this analysis. The region is rich in energy resources and currently enjoys relatively stable and affordable electricity. Except in the case of Botswana, Mauritius, Namibia and South Africa, final energy demand is dominated by the residential sector in the form of biomass. Energy consumption or final energy demand in Angola, Botswana, Mozambique, South Africa, Tanzania, Zambia and Zimbabwe is projected to 2030 using a Long Range Energy Alternatives Plan-ning (LEAP) model in a ‘business as usual’ scenario, the other countries being left out because of poor quality data. The projections are carried out by relating historic sectoral GDP and population growth in each country to energy demand and then using the historical link and the projections of these drivers to project energy demand. The analysis under this ‘business as usual’ scenario seems to indicate that we can expect to see a large increase in consumption in these countries, especially in the form of biomass and electricity. In both cases, supply is a concern. Having established what the present resources are; what some of the supply elements are currently in place; what the base-year demand is; and some basic relationships between demand and socio-economic drivers, this paper sets the stage for further studies that include the future energy supply; regional trade; and scenario analysis using indicators of sustainable development for the region. However, further analysis of the regional energy system, is only valuable if it is supported by good data. A reliable energy balance is needed for the countries not modelled here, and in the case of the modelled countries, better data is also needed, especially in the use biomass.

Adverse Environmental Conditions

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.
