Growing demand for energy, along with the depletion of traditional fossil fuels and the development of civilization, raises interest in the use of bioenergy in all sectors of the economy, including electricity, transport, heating, cooling, and industry. In developed countries bioenergy is an alternative to traditional non-renewable energy from fossil fuels, as its resources renew in natural processes, making it practically inexhaustible. Due to the reduction of greenhouse gas emissions, bioenergy is also more environmentally friendly than fossil energy. Thus bioenergy sector is a key segment of bio-economy and determines its competitiveness and development. Increase in bioenergy production, resulting from both market and energy policies, leads to greater interdependence between energy and agricultural markets, affects food and feed prices and change in land use. The aim of this study was to identify changes in the bioenergy market in Poland in 2010-2015, present the role of bioenergy sector production in the structure of bio-economy, the changes in production and directions of biomass-based energy use and determine the importance of the major bioenergy markets in the structure of the energy market in Poland. The study was based on the aggregated statistical data on the acquisition and consumption of bioenergy in Poland, including energy from municipal waste, solid biofuels, biogas and liquid biofuels. Findings prove that bioenergy is the most important renewable energy source in Poland. It is also a diversified source of energy, as it can be converted into solid, liquid and gaseous fuels. Although solid biofuels and liquid biofuels dominate in Poland, the share of biogas and energy produced from municipal waste is small. Concluding, bioenergy in Poland changes its character from traditional and local energy source into modern, international commodity.

The article deals with a current trend of the global energy market, which is characterized by rising tension in relations between the performers of the energy market regulation mechanisms, and it leads to the emergence of alternative energy sources. The article is called to identify the causes of renewable energy markets nascence, to make comparative description of Ukrainian and European Renewable Energy Markets attractiveness, and to characterize the state policy change in a renewable energy market. Different interpretation of nature and classification of the field of renewable energy in foreign and Ukrainian approaches shows the problem of legal criteria of renewable energy markets regulation. It is proved the existence of double barrier penetration of the European market for renewable energy for Ukrainian companies, which includes compliance with the accepted EU Directives and compliance with the Rules of each member individually. The presence of clearly defined standards and certificates of quality for the European market allows producers to show the competitiveness of Ukrainian products in the international market and stimulate Ukrainian manufacturers. The presence of clearly formulated laws, stable and balanced political and legal environment of the EU allows Ukrainian producers of renewable energy to develop such a strategy that considers the time factor, as the primary parameter of competitiveness in international business. The market of solid biofuels in EU is under formation, its development timeframe and uncertainty of environmental risks becoming is especially important for Ukrainian producers.

Energy is considered a critical driver of social and economic progress, but the use of conventional energy from fossil fuel sources is viewed as the main contributor to greenhouse gases that cause global warming. To overcome such issues, renewable energy technologies appeared as a viable substitute which lessens pollutant emissions and protect the environment. This paper investigates the impact of energy consumption and environmental pollution on economic growth, also exploring the causal associations, for a sample of 11 Central and Eastern European states over the period 2000 to 2016. The outcomes of panel data regressions indicate evidence of a non-linear link between renewable energy (both overall, as well as in form of hydro and wind power) and gross domestic product per capita growth. The non-linear relations were also established in case of alternative & nuclear energy and fossil fuel energy consumption. However, the influence of non-renewable energy on growth was not statistically significant, whereas greenhouse gases emissions exhibited mostly a positive impact on economic growth. The robustness checks by panel fully modified and dynamic ordinary least squares showed almost the similar pattern of results. The results of Granger causalities within six panel vector error correction models supported in the short-run the conservation hypothesis for renewable energy (overall), but also for hydro power and solid biofuels, excluding charcoal. In the long-run the growth hypothesis was established for renewable energy (overall), along with wind power, solid biofuels, excluding charcoal and geothermal energy. The findings imply that CEECs policy makers should consider imperative investments in the development of renewable energy sector.

The growing global demand for energy, as well as the global demand for a higher share of the use of renewable energy sources, is leading to intensive development of the production of solid biofuels in the form of pellets. Biomass pelleting technology is successfully used to produce solid high-grade biofuel in the form of pellets. This biofuel is currently an important trade item in the energy markets. The development of pelleting technology also brings higher demands on pelleting machines and tools. Pressing tools are the powerful core of the entire technological line for the production of solid biofuels. The paper deals with biomass pelleting technology and describes the requirements and limits of this technology. It focuses in great detail on the pressing tools of pelleting machines. The work examines in detail the design of pressing dies and pressing rolls. The above knowledge are based on the personal experience of the authors as designers of pelleting machines and tools. The published information is of great practical importance for the development of pelleting technology and for moving forward in the design of pressing tools

The aim of the executed research is to determine the influence of harvesting renewable energy on the labour market. Eurostat Databases provided a source of empirical data concerning the amount of produced energy. The number of the employed and the performance of the installed equipment were determined thanks to reports drafted by EurObserv’ER or International Renewable Energy Agency (2016). The following sectors were considered: solid biofuels, biogas, liquid biofuels, geothermal, hydropower, municipal waste, solar photovoltaic, solar thermal and wind power. The research concerned 28 member states of the EU between 2009 and 2015. The results presented were based on averaged data on both employment and the volume of primary energy production and installed capacity. The estimated models show that the solar and wind energy sectors were characterized by the highest labor intensity in the analyzed period.

Solid biofuels such as woodchips have always been a significant source of fuel in the field of renewable energy. However, the drying of wood chips has been a challenge in preparing biofuels and other applications. The moisture content of below 25% in the wood chips of grade EN 14961 is considered the premium wood chip material. Solar drying emerged as a leading solution for the drying of wood chips. The paper investigates the comparison of moisture removal rate using a natural convective solar dryer compared to open sun drying developed at Miskolc, Hungary (48°06'15.0"N 20°47'30.0"E).
