The agricultural biogas market differs in different European countries. Both in Europe and in Poland, the basic form is the use of biogas to generate electricity and heat. In nine EU countries, the biogas produced is also used in local gas networks and in transport, especially communal. Biogas production can be based on agricultural raw materials (Germany) or the use and processing of all agricultural, industrial and municipal waste (Denmark, Sweden). The aim of this article is to present dynamics and structure of biogas market development, raw materials used and profitability in various legal and financial models. The presented analyzes have concluded that biogas plants could be an important part of the energy market in the future, particularly at the local level and an important part of a sustainable economy.

In energy policy, various organizational forms are used. At local and regional levels, energy cooperatives and energy clusters are perfect. Their main advantages are: socialization of the production process, combining social and economic goals and a beneficial effect on the improvement of the natural environment. The aim of the article was to recognize the conditions and state of development of energy cooperatives and energy clusters in Poland and their impact on local development and the entire energy sector as compared with similar activities in Germany. Germany has the largest number of energy cooperatives that operate in the European Union. They lead to the development of civic energy in which the interests of energy producers and consumers are integrated on a large scale. The conducted analysis led to the conclusion that energy cooperatives should have flexible structures resulting from local needs and possibilities, starting from social cooperatives to structures functioning in the form of regional clusters

Artykuł opisuje następstwa procesu restrukturyzacji sektora rolnictwa państwowego na obszarze Polski Północnej i Zachodniej. Pomimo, że od początku zmian minęło już 20 lat, to ich skutki widoczne są do chwili obecnej. Na obszarach, na których dominowała własność państwowa, nadal występuje wysoki wskaźnik bezrobocia, niski wskaźnik aktywizacji zawodowej oraz znaczne uzależnienie mieszkańców od pomocy społecznej. Częściej niż na innych obszarach, występuje zjawisko marginalizacji i wykluczenia społecznego. Długotrwałe działania, jakie są podejmowane przez instytucjonalne podmioty społeczne nie przynoszą spodziewanych efektów. W artykule zaproponowano wykorzystanie zasobów pracy i ziemi na tych obszarach do pozyskania biomasy energetycznej i jej lokalnego zagospodarowania. Działalność tę należy traktować jako jeden z czynników aktywizacji obszarów wiejskich i kształtowania nowej funkcji rolnictwa.

The article analyzes both existing and proposed legal acts in the field of promoting and generating energy from renewable sources. The model of energy management based on renewable sources is implemented differently in individual countries. With the increasing share of renewable energy and the level of objectives for the coming years, it is essential that they are achieved with the lowest possible cost of support from public funds. For this reason, many countries have decided to gradually move to the auction system, giving control over the costs, structure and capacity increase of new RES installations. The research problem is the evaluation of the effectiveness of the auction system against the background of the instruments used so far, both in terms of the increase in new generation capacities and the costs of achieving the intended objectives. These issues, due to the short period of functioning of the new system, have not been properly identified yet. The study uses data from the years 2010-2018. The spatial range was mainly in Poland, but examples from other countries around the world were also used. The research and analysis used a comparative method and a list of individual renewable energy production technologies according to the analyzed values. It has been hypothesized that an auction system based on competitive principles, more effectively and with lower support of public funds will allow for achieving goals related to the promotion of renewable energy sources. The aim of the article is to present the current and new RES support system, prices obtained in auctions and the first experience in its implementation. The research material were Eurostat and GUS statistical materials, documents from the European Commission, the Ministry of Energy, the Energy Regulatory Office, reports on support systems from European countries and Poland. Research methods used in the work include analysis of documents, normative acts, subsequent amendments to the Act on renewable energy sources and regulations issued on their basis. The assessment and recognition of the level of support in the auction system in countries that have been using this instrument for many years was also made. These analyses allowed the assessment of the effects of the auctions carried out, their advantages and disadvantages, and helped formulate conclusions in the field of organizational changes ensuring efficient functioning of the auction system.
