The specific objectives were to assess the degree of concentration of renewable energy and the pace of changes in the volume of production of this energy from individual sources in the countries of Central and Eastern Europe, as well as to determine the structure according to renewable energy sources to show the directions of changes. Central and Eastern Europe countries were covered in the research, meaning that a total of 23 countries were included in the analysis. The data used in the study was obtained from the IRENA and World Bank databases. The research period covered the years from 2011 to 2019. For data analysis, the following methods were used: Index methods, Gini coefficient, Lorenz curve, and Grade Data Analysis. The development of the renewable energy sector and modernisation of the energy structure are of great importance for countries to meet their climate obligations. Large-scale energy production from renewable sources could reduce a 60% reduction in the temperature rise. Additionally, such activities will contribute to an increase in energy efficiency by 90%. The energy transition would also bring more comprehensive social and environmental benefits. Thus far, researchers have dealt with energy consumption-related problems in Central and Eastern Europe countries. This article focuses on the production of renewable energy in countries of Central and Eastern Europe. The article fills the research gap in this area. It refers to the situation in the countries of Central and Eastern Europe at a time when developing renewable energy has become very important. In our analysis, we examine renewable energy production in countries located in one region but are and are not EU members. Thanks to this, it will be possible to observe differences in terms of belonging to economic groups. In the case of the pace of changes and the structure of renewable energy produced, a difference can be found between the EU member countries of Central and Eastern Europe and the group of countries outside the EU. The fastest renewable energy production growth was achieved in EU member countries of Central and Eastern Europe. In the case of the mentioned countries, the production of solar, wind, and bioenergy was developed. In other countries, hydropower production was set and treated as a traditional energy source. Generally, in countries of Central and Eastern Europe, the development of energy based on renewable energy sources was not dependent on the pace of economic development of the country. Decision-makers in the countries of Central and Eastern Europe should develop the production of renewable energy from sources that are the easiest and cheapest to use. This is the only way to increase the production of renewable energy in developing countries.

The specific objectives are to highlight the directions and differentiation of price changes in EU states, determine the degree of volatility (or stability) of electricity rates, and establish the correlation between electricity prices for household consumers and economic and energy parameters. All members of the European Union were chosen for this project as of 31 December 2019 (28 countries). The analyzed period covered the years 2008-2019. The source of collected information was the thematic literature review and the data from Eurostat. Descriptive, tabular and graphical methods, constant-based dynamics indicators, coefficient of variation, Kendall's tau correlation coefficient, and Spearman's rank correlation coefficient were used to analyze and present the materials. It was determined that higher electricity prices for households in the EU states were associated with better economic parameters. Developed countries must have higher energy rates because they will ensure energy transformation, i.e., implementing energy-saving technologies. In the EU, electricity prices for household consumers showed little volatility, but that variability increased in line with the surge of the volume of household energy consumption.

Tytuł pracy: Energy Self-Subsistence of Agriculture in EU Countries Tytuł czasopisma: Szczegóły: 2021, Vol. 14, issue 11, article number 3014 p-ISSN: 1996-1073 Charakterystyka formalna: artykuł w czasopiśmie zagranicznym Charakterystyka merytoryczna: artykuł oryginalny naukowy Charakterystyka wg MNiSW: artykuł w czasopiśmie z IF (wykaz MEiN) Język publikacji: ENG Wskaźnik Impact Factor ISI: 3.252 Punktacja ministerstwa: 140.000 Słowa kluczowe ang.: agriculture ; bioenergy ; energy policy ; renewable energy sources https://www.mdpi.com/1996-1073/14/11/3014 DOI: 10.3390/en14113014 Streszczenie: The paper's main purpose was to identify the level and factors influencing the consumption of bioenergy of agricultural origin in agriculture in EU countries. All EU countries were deliberately selected for research, as of 31 December 2018. The research period covered the years 2004 to 2018. The sources of materials were the subject literature, Eurostat data, and IEA (International Energy Agency) data. The following methods were used for the analysis and presentation of materials: descriptive, tabular, graphical, Gini concentration coefficient, Lorenz concentration curve, descriptive statistics, Kendall's tau correlation coefficient and Spearman's rank correlation coefficient. In the EU, there was a high level of concentration of renewable energy consumption in several countries. There was also no change in the use of bioenergy of agricultural origin in agriculture, but the concentration level was low. The degree of concentration has not changed for both parameters of renewable energy over a dozen or so years, which proves a similar pace of development of the use of renewable energy sources in individual EU countries. Higher consumption of bioenergy of agricultural origin in agriculture was shown to occur in economically developed countries, but with high agricultural production. There was a strong correlation between the consumption of bioenergy of agricultural origin in agriculture for the entire EU and individual economic parameters in the field of energy and agriculture. The relations were positive for all economic parameters, for total renewables and biofuels consumption and for agricultural production parameters. Negative relations concerned the total energy consumption and parameters related to the area of agricultural crops.
