Consumption Efficiency

Lithuania, as many other EU countries, encounters key challenges in three energy sector fields: energy independence, energy sector competitiveness and sustainable energy sector development. Such situation is determined by historical and political conditions, as well as by limited internal energy resources. In such context an importance of energy consumption efficiency pursuing country energy sector sustainability is highlighted. By implementing the long-term goals and tasks a country may seek to increase the efficiency of energy production, distribution and consumption, as well as to increase energy production from renewable and waste energy sources. The main objective of the paper is to analyze the efficiency of energy consumption, the factors influencing energy sector competitiveness and sustainability, and to assess the development soundness of the use of renewable energy sources in Lithuania. The paper discusses the main EU legal documents and their provisions regulating energy sector, analyze energy production and consumption efficiency data in Lithuania and reveal the economic effect of the use of renewable energy sources in Lithuania.

Price Increases

Conditions of energy sector development correlated with shrinking resources of the conventional energy sources, increased importance of environmental policy as well as continual price increases cause that the territorial governments should, within the scope of their competences and abilities, rationalise energy consumption and costs. This paper presents the tools for energy sector rationalisation in a commune with consideration of the opportunities for optimisation of energy consumption costs within municipal resources by applying the ESCO model. The paper also draws attention to the possibility of utilising the resources of renewable energy sources by communal governments based on the example of wind energy, of which Warmia and Mazury has some of the largest resources in Poland.

North Eastern

The region of Warmia and Mazury in Poland is fourth largest voivodeship which occupies 7,7 % of the country’s territory. The Region of Warmia and Mazury in north-eastern Poland is situated at a distance from conventional energy sources. Therefore, the Region is a Polish leader in power generation from renewable energy sources. The structure of electrical grids in the Region of Warmia and Mazury is poorly developed and insufficient. Therefore, electric power infrastructure should be expanded and modernized as part of energy sector development to increase energy efficiency as well as electricity and heat production from renewable energy sources. The Region of Warmia and Mazury is characterized by a considerable discrepancy between energy generation and energy use. It recent years, electricity consumption exceeded energy production more than 10-fold. The region has to purchase energy from external sources and develop new generation methods, in particular those that rely on renewable resources of energy. In Warmia and Mazury, the most popular renewable energy sources include biomass, wind turbines, solar and photovoltaic panels, hydropower, heat pumps and geothermal energy. The region is characterized by distributed energy generation in small polants that carter mostly to local needs. The University of Warmia and Mazury in Olsztyn has developed, in collaboration with the Warmia and Mazury Energy Agency, a renewable energy strategy for 2010-2020 in the Region of Warmia and Mazury. The strategy is consistent with the Polish Energy Policy and the national plan for the use of renewable energy sources. In the region Warmia and Mazury, efforts are being made to generate 14,000 TJ of energy from renewable sources ( approx. 18,4 % of energy consumption in the region) and 1,700 GWh of electricity (approx. 49 % of energy consumption in the region), reduce CO2 emissions in the energy sector by 1,530,000 tons, and the decrease energy consumption per unit of GDP (PLN 1 million) from 1.94 TJ to 1.67 TJ by 2020.

In this article, we aim to identify the determinants that profoundly impact renewable energy sources development in Poland. To this end, the authors have conducted qualitative and quantitative analyses of Poland’s renewable energy sector. In this paper, we demonstrate an original approach considering the different development levels of the given sector across provinces (voivodeships). It uses panel data from the Local Data Bank of the Statistics Poland on electricity production from renewable energy sources in individual voivodeships in Poland from 2005 through 2019. The study confronts the results of previous studies and sheds light on the situation in Poland—specifically, upon the changes that have happened over the ten years (2010–2019). The qualitative analysis shows a negative correlation between energy consumption and the share of renewable energy sources in total energy production. Evidence shows that favorable changes are underway in the energy production structure: RES share is growing and by degrees satisfying energy demand, and there is growing potential of energy entities in Poland. Furthermore, the analysis shows that R&D and total expenditures on environmental protection and water management investments do not significantly affect the development of RES. A dynamic panel data model has been used to analyze the group and time effects on the dependent variable. The findings confirm the existence of the persistency effect and indicate positive effects of total installed electric capacity (IEC) and household electricity consumption (HEC). Nonhousehold electricity consumption (NHEC) has a negative effect on the endogenous variable, i.e., the renewable energy sources share in the gross final energy consumption (RESS). The research results may be applicable as recommendations for energy efficiency policy development based on renewable energy sources depending on the RES development level in the regions of Poland.

Abstract The utilization of renewable energy sources has an increasing role in the EU’s climate and energy policy. There are several reasons for increasing the use of renewable energy. The motives are the reduction of imported dependence on fossil fuels, mitigation of the adverse environmental impact of the energy sector and boosting of industrial development. The study provides a comprehensive overview on the structure and utilization of energy production of the Visegrad countries, focusing on the dependence on energy imports. The purpose of the article is to analyze the gross inland energy consumption of the Visegrad countries and to examine the relationship between renewables and non-renewable energy sources. In the course of the analysis, we tried to find out which non-renewable energy carrier is replaced by the renewables.

Energy Independence

In many countries, energy security is treated as a priority for the coming decades, and at the same time energy production from the vast majority conventional energy sources does not meet environmental protection criteria. Hence, the need to use renewable energy sources (RES), which can largely satisfy energy needs. The aim of the study was to identify possibilities of creating autonomous energy regions (ARE) in Poland, based on renewable energy sources. Attention was paid to the role and significance of the potential of rural areas in this respect, taking into account the possibilities of increasing energy production from these sources in individual regions of Poland. The research was conducted on a regional level (division into voivodships) and on a local level (division into powiats, which form voivodships). When assessing the potential for constructing ARE based on RES, the following energy sources were taken into account: water, wind, sun, biogas and biomass. It was found that the highest RES potential versus energy consumption can be obtained in powiats where the share of arable land and forests exceeds 80%. The research showed that in most regions of Poland (powiats, voivodships), there is a large potential for obtaining additional energy from RES, which would cover over 73% of the country’s demand for electricity. This could be the basis for building energy independence on a local scale. The results of the study indicated that as many as seven regions would become self-sufficient in terms of electricity demand.

AbstractThe development of bioenergy markets is beneficial from a climate perspective and helps ensure sustainable forest management both locally and globally. This study aimed to provide an overview of the current state of Lithuanian forest biomass resources with a particular focus on the legal, economic and ecological aspects of forest biomass use for energy and to identify the lessons that should be learned from the history of biomass introduction in the country’s energy sector. These experiences and lessons are valuable both nationally and internationally, where good practices and challenges for the introduction and development of forest biomass for energy production are revealed. We examined the question of whether regulatory drivers in the energy sector can increase forest biomass use for energy production and contribute to sustainable development of Lithuania. To answer this question, we described the legal and market instruments regulating forest biomass use for energy production, the forestry sector and renewable energy policy in Lithuania, the current and potential amount of forest biomass available for energy production and ecological considerations relating to forest biomass use for energy. In Lithuania, forest biomass resources are strategically important for the renewable energy sector. The National Energy Strategy of Lithuania aims to increase the share of renewable energy sources, including forest biomass, within the total energy consumption, with targets of 30% in 2020, 45% in 2030 and 80% in 2050. Lithuania successfully achieved the target of EU legislation on renewables in 2015 ahead of the obligation to achieve it in 2020. Renewable energy is mainly used in heating, as well as in the electricity and transport sectors. This has resulted in a significant price reduction for end users due to the increased use of biomass, mainly local forest biomass, for heat energy production and in the emergence of a biofuel exchange, which acts as a system of biomass auctions that to some extent prevent unjustified price increases. Legislation developed for the energy biomass market in Lithuania allows efficient restructuring of the energy sector, especially for heat production. The Lithuanian energy sector has already successfully replaced imported and relatively expensive natural gas with locally available cheaper renewable energy sources (RES). Compliance with formal environmental regulations is required to protect the soil, ground vegetation, understory and biodiversity during commercial tree harvesting. Lithuania has basic guidelines for the use of wood ash as a compensatory fertiliser, with strict requirements for the chemical quality of wood ash.

The Relationship

In this contemporary era, environmental problems spread at different levels in all countries of the world. Economic growth does not just depend on prioritizing the environment or improving the environmental situation. If the foreign direct investment is directed to the polluting industries, they will increase pollution and damage the environment. The purpose of the study is to consider the relationship between foreign direct investment in Kazakhstan and Uzbekistan and economic growth and renewable energy consumption. The study is based on data obtained from 1992 to 2018. The results show that there is a two-way link between foreign direct investment and renewable energy consumption in the considered two countries. The Granger causality test approach is applied to explore the causal relationship between the variables. The Johansen co-integration test approach is also employed to test for a relationship. The empirical results verify the existence of co-integration between the series. The main factors influencing renewable energy are economic growth and electricity consumption. To reduce dependence on fuel-based energy sources, Kazakhstan and Uzbekistan need to attract energy to renewable energy sources and implement energy efficiency based on rapid progress. This is because renewable energy sources play the role of an engine that stimulates the production process in the economy for all countries.
