“…The Polish power industry is in an energy transformation process [10]. In Poland, the proportion of energy from renewable sources to the total primary energy generated increased from 11.73% to 14.46% in 2012-2018 [11].…”

The aim of this study was to investigate the influence of biomass micronization on energy production using a converted aircraft turbine AI-20. The test system was constructed in such a way to ensure continuous operation for a given period of time and was equipped in a chopper, a flail mill, and a micronizer. The turbine had the ability to produce energy from solid biomass and as well conventional fuels. The most energy was obtained from absolutely dry sunflower husk (17.27 MJ/kg) and the least from Poplar (7.82 MJ/kg). Miscanthus, wheat straw, and hay (approximately 17 MJ/kg) showed high values of energy production. In addition, the thermal decomposition of wheat straw at 350 and 450 °C was studied using the Py-GC/MS technique in a helium atmosphere to determine the gaseous compounds formed during biomass gasification under anaerobic conditions. The results obtained indicate the formation of compounds classified as phenols (vanillin, hydroxymethylfurfural).

The main purpose of the study was to identify the level and factors influencing investments in renewable energy sources (RES) in basic local government units in rural areas. The specific objectives were to define the conditions for the development of renewable energy sources in Poland, to determine the directions of changes as well as the importance of renewable energy in Poland, to present the relationship between the level of expenditure on renewable energy and budget components in rural and rural-urban communes. The Świętokrzyskie voivodeship (Voivodship—a unit of the highest administration level in Poland, since 1990 a unit of the primary territorial division of government administration, since 1999 also a unit of local government, there were 16 voivodships in Poland.), which is one of the centrally located voivodeships in Poland, was purposefully selected for the research. The research period covered the years 2016–2019. The sources of materials were the literature on the subject, as well as empirical materials obtained at the Voivodeship Statistical Office. The following methods were used for the analysis and presentation of materials: descriptive, tabular, graphical, Gini concentration coefficient, Lorenz concentration curve, Kendall’s tau correlation coefficient and Spearman’s rank correlation coefficient. Poland is one of the countries with quite high dependence on hard and brown coal. Changes in the structure of energy sources are slow. Investments in renewable energy are necessary. The problem in this respect is the lack of a proper law. Despite this, investments in renewable energy are being made in rural areas. In the Świętokrzyskie voivodeship, only 28% of communes made such investments. It was found that only in urban rural communes the amount of investment expenditures in renewable energy sources was related to the level of budget expenditures and property expenditures of the commune. The amount of support from the European Union aid funds was positively correlated with the level of expenditure on investments in renewable energy. Therefore, it can be concluded that without the support from EU funds, it is not possible to invest in renewable energy in local government units.

“…Most of the expenditure related to renewable energy is related to the materials and labor needed to build and maintain facilities. However, there are no costs of importing energy [25][26][27]. The main advantages of renewable energy include ensuring energy security for the future, which means a continuous and uninterrupted supply of energy necessary to run the economy [28].…”

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.
