Exploitation of renewable energy sources for power generation has been more and more important in recent years. This results from the economic issues and the measures taken to ensure the energy security. The aim of this research was to determine the significance of renewable energy sources (RES) in the energy mix of Poland, and to elicit the opinions and the level of knowledge of the society on the use and development of non-conventional energy. The article also presents advantages and disadvantages of types of RES, the obstacles which hinder the progress of green energy in Poland, and the proposed measures to expand the share of the RES in the overall energy mix. The research relied on the statistical data gathered by Statistics Poland. The opinions of respondents were elicited through a diagnostic survey based on a questionnaire. The research has demonstrated that the respondents support the development of RES in Poland. However, they also maintain that the purchase and installation of devices for the production of non-conventional energy are too expensive. The respondents believe that in order to increase the number of green power plants, subsidies to encourage RES investment and tax reliefs related to this investment should be bigger.

A crucial factor that determines the development of production and consumption markets for biofuels is the choice of raw materials that can ensure the highest possible production efficiency, the lowest cost and the smallest emission of harmful substances to the atmosphere during all production stages. Considerations underlying the development of biofuel production have been discussed as well as the theoretical mechanisms linking the generation of biofuels to the level of production and the variability of prices of agricultural raw products. The aim of this study has been to identify the scale at which energy raw materials originating from agriculture are used for liquid biofuels production and to explore their impact on food security. The study used public statistical data (OECD-FAO and IndexMundi). The time span of the analysis was from 2005 to 2018. First-generation biofuels based on food raw materials (cereal grains, root crops, sugarcane and vegetable oils) are becoming increasingly competitive with food production recent years have been a period of the dynamic growth in production of liquid biofuels. In 2018, the global production of these substances reached 167.9 billion litres (bioethanol and biodiesel together), consuming 16.1% of maize grain, 1.7% of wheat grain, 3.3% of grain of other feed grains and 13.5% of vegetable oil.

Biomass is playing an increasingly important role as a source of renewable energy. The aim of this study has been to identify the potential applicability of straw from agricultural crops to generate energy within the district of Braniewo, in the province Warmia and Mazury, Poland. The study covered the years 2015 to 2017. Based on statistical data, and using appropriate equations and norms, the structure of crop production and the number of livestock in the mentioned district were analysed; the potential production volume of straw was estimated, from which the amount needed for animal production (feed and bedding) was deducted, while the organic substance balance in soil was calculated. An annual average amount of straw remaining to be used for energy purposes in the district of Braniewo is about 41,531 t of straw, equivalent to about 60,222 GJ of energy (24,088 t of coal). In addition to the above analyses, a survey was conducted among local farmers, which showed their opinions about barriers to and opportunities for growing crops for energy purposes and using renewable energy resources. The survey results justify the claim that there is certain potential among farmers in the district of Braniewo to grow crops for energy purposes.

Growing environmental and climate problems in the contemporary world necessitate the search for efficient solutions, including changes in agriculture, which has been reflected in the new package of reforms of the EU climate policy, called the European Green Deal (the EGD). Agriculture and rural areas play an essential role in the attainment of the EGD goals, and one of the prerequisites for an effective implementation of the EGD assumptions is to recognize the mechanism underlying the activity of agricultural farms in the scope of pro-environmental measures implemented under the Common Agricultural Policy (CAP). This article presents an endeavour to make a multidimensional evaluation of the spatial diversification in such activities, using Polish farms as an example. Compared to other EU member states, Poland is a country where agriculture remains a substantial sector in the national economy. This research is based on data from several institutions, including the Central Statistical Office (CSO) and the Agency for Restructuring and Modernisation of Agriculture (ARMA), responsible for the allocation of funds from the EU budget and for providing support to the development of agriculture and rural areas. The level and structure of the absorption of funds from the CAP underwent analysis, including three pro-environmental measures of the Rural Development Programme: organic farming (OF), agri-environment climate measure (AECM), and afforestation and creation of forest areas (ACFA). In order to achieve a holistic approach to these measures, an innovative analytical model was developed. It can be applied to analyses on a regional, national, and European level, and it is based on several novel indicators, as well as advanced statistical and spatial analyses. The research demonstrates that the pro-environment activities of farmers are characterized by a significant geographical diversity. The most active in soliciting payments from the CAP were agricultural farms with a high level of pro-environment internal characteristics of agriculture (IPEAF = 30.1%, with national average = 11.6%). With regard to anthropogenic determinants, relatively higher values of the IPEAF indicator were found in the municipalities with a lower level of socio-economic development (12.1%) and those located in northern and western Poland, within the borders of the former Prussian Partition (18.6%), characterised by higher farming culture. The research results imply that the effectiveness of the up-to-date solutions needs to be improved, also by taking into consideration the endogenous conditions and potential of individual territorial units. The research results also prove the expediency of implementing the European Green Deal. Conducting an analysis of the pro-environmental activity of farms, taking into account both the applications of the current CAP financial perspective and those resulting from follow-up activities regarding the previous perspective, is an innovative approach to the issue.

Analyses of statistical data were made and their results discussed in this article to identify the level of Poland’s energy security and to determine the role of agriculture in ensuring it. It has been demonstrated that coal continues to be the staple resource for the generation of energy in Poland. The current demands and requirements concerning the reduced consumption of non-renewable resources and Poland’s obligations towards the European Union regarding the production of energy from renewable resources—all these considerations contribute to the promotion of a skillful development of energy crop farming, which, in Poland, is likely to be very successful. Agriculture plays an important role in ensuring Poland’s energy security, and this branch of farming can grow dynamically provided adequate legal regulations and promotion are in place. The chief resource for renewable energy generation is biomass. Straw and biogas production in agricultural biogas plants are two solutions whose full energy production potential still awaits to be tapped.

Europe is currently facing the potentially biggest energy crisis in history. There are many reasons for this, and the current geopolitical situation makes it clear that we are being forced to take immediate action to ensure sufficient energy supplies to consumers. Until recently, the European Union was dependent on Russian energy resources (mainly oil and gas). For many years, the EU countries had been shutting down their own production and importing much cheaper raw material from Russia. The threat of a blackout is becoming increasingly possible. European governments are preparing businesses and households for the energy crisis in various ways, but there is also a great deal of mobilization to accelerate the development of renewable energy sources (RES). The aim of this study was to identify the barriers and prospects for RES development in Poland in the current geopolitical conditions. The reasons for insufficient grid HC were analyzed. Additionally, the article aimed to assess the prospects for solar energy development in Poland. Wind power was discussed only in general terms because the development of wind farms is inhibited by the regulatory framework. Particular attention was paid to hosting capacity (HC) and the condition of the power infrastructure as the main determinants of RES development in Poland. Numerous documents developed by power companies and government agencies responsible for implementing and managing energy in Poland were analyzed. Special attention was paid to legal regulations and the need for legislative changes. As a country, Poland has one of the highest growth rates in photovoltaic (PV) installations. The forecasts for increasing HC, as a prerequisite for RES development in Poland, are not promising.
