The aim of this paper is to define the factors influencing the level of energy poverty among students. The analysis of these factors is based on the results of a survey conducted among a group of 937 students at the Cracow University of Economics. The study takes into consideration the changes in the attitudes and behavior of students resulting from the introduction of distance learning during the COVID-19 pandemic. The switch to distance learning resulted in a significant increase in the number of responses related to feeling ill or sick due to inadequate temperature (from 24% before a lockdown to 32% after the introduction of a lockdown). Students experienced temporary surges in their overall living costs due to the pandemic, especially during the first wave. The respondents who experienced inappropriate temperatures (inadequate heating) due to excessive costs felt ill or became sick more often than others. The study demonstrated that those who pay more for energy (defined as a surplus payment in excess of 10%) tended to be, on average, less energy-aware than others. The following indicators of energy poverty among the students were distinguished: high living costs, small degree of influence over the choice of living quarters, as well as concerns over energy efficiency and environment. The conclusions drawn from the conducted studies may be utilized to design public policies aimed at curtailing the phenomenon of energy poverty among students. This issue is particularly prominent in large urban agglomerations where the costs of living are high and result in the feeling of pressure regarding the need to save money on thermal energy consumption.
Biogas development is expected to contribute to the National Recovery and Resilience plan to overcome the COVID-19 shock. Estimation of the agricultural biogas potential in economic terms can contribute to refining policies inciting effective sector development. In this paper, we attempt to do so by modeling a biogas chain from dedicated crops and livestock waste. This was achieved by coupling farming models to the biogas industry in a partial equilibrium framework. This allows for a comprehensive investigation of alternative measures in technology, size, spatial distribution and land use change. The integrated model was implemented in Lubelskie for the previous policy (green certificates) and the current policy (auction market). In both cases, the bottom-up profit driven optimization resulted in approximately 40 MWel, which shows a robust economic potential more than four times the biogas sector’s actual capacity in the region, also providing the detailed structure of the sector. When focusing on the industry structure, both scenarios give similar results regarding 1–2 MWel plant size close to the observed situation. The model also suggests a large number of new facilities <250 kWel, twice as important under scenario 2, indicating that other conditions beyond economy profitability should be fulfilled for further sector development.
The phenomenon of increasing tuition fees is one of the factors which reinforce the increasingly consumerist attitudes among students towards the product (understood as a whole process of university education) they receive from universities. The aim of the study is to characterise the difference between the expectations of students and the extent to which those expectations are met by universities. This analysis also focuses on the conditions that determine this perception of what universities offer and discusses selected issues concerning the relations between universities and industry. The findings demonstrate why creativity, apart from practical knowledge, is one of the most important aspects in the process of education, where a student’s graduation work is aimed at solving specific problems in companies and institutions. In the empirical part of the paper, students’ opinions about the importance of selected aspects of the education process are compared with the level of support provided by universities. The research covered 505 students of economics from 10 different countries. Their expectations of the educational process with regard to the majority of its aspects (apart from theoretical knowledge) proved to be higher than those of their universities. The findings of this research may thus be useful in formulating optimal study plans.
The agricultural biogas sector is now facing the opportunity to become a significant actor in the new energy deal as a low-carbon source of electricity. Given the current prospects for rapid growth in the industry, the authors developed an economic model of a medium-sized agricultural biogas plant to assess the rate of return on such an investment. The analysis comprises energy prices, substrates, and other costs reported by the plants already in operation, as well as the electricity sales support system, the actual biogas and electricity yield from the substrates, and the digestate utilisation. It shows that a biogas plant capable of delivering ca. 2000 MWe generates a profit in a much shorter timeframe than 20 years, even under quite uncertain economic conditions. In the model scenario, the breakeven point is reached at slightly below 5000 MWh of power output or at ca. 5800 MWh including financing costs, with a planned annual output of approx. 8000 MWh. The profitability of the model biogas plant was also demonstrated by calculations made for other scenarios which differ in substrate composition and financing structure. The parameters of the econometric model are based on the data collected from a group of 41 units that use only organic plant matter for biogas production.
