The European Union has set targets for renewable energy utilization. Poland is a member of the EU, and its authorities support an increase in renewable energy use. The background of this study is based on the role of renewable energy sources in improving energy security and mitigation of climate change. Agricultural waste is of a significant role in bioenergy. However, there is a lack of integrated methodology for the measurement of its potential. The possibility of developing an integrated evaluation methodology for renewable energy potential and its spatial distribution was assumed as the hypothesis. The novelty of this study is the integration of two renewable energy sources: crop residues and animal husbandry waste (for biogas). To determine agricultural waste energy potential, we took into account straw requirements for stock-raising and soil conservation. The total energy potential of agricultural waste was estimated at 279.94 PJ. It can cover up to 15% of national power generation. The spatial distribution of the agricultural residue energy potential was examined. This information can be used to predict appropriate locations for biomass-based power generation facilities. The potential reduction in carbon dioxide emissions ranges from 25.7 to 33.5 Mt per year.

It is well known that the utilization of renewable energy sources is inevitable for a sustainable future. Besides the fact that other energy sources such as coal, gas or nuclear power have limited reserves the proper use of increasingly higher shares of renewable energy sources may lower negative impacts of traditional energy sources on the ecosystems. This is especially important in naturally protected areas located in remote Earth locations. Such areas are still almost untouched by mankind, e.g. Antarctica. The research activities in the area of renewable energy sources have increased rapidly within the last few decades. It is of a global interest to carry out the research in an ecologically sensitive way, i.e. balance the outputs and the effects of infrastructure on environment. In this paper, a project of installation of a photovoltaic system on the Czech Antarctic Station (Johann Gregor Mendel) on the James Ross Island is described and the first experience from the system run is reported. The contribution of this system to the overall energy production on this station shortly after commissioning of the system is presented as well. In discussion, a possible future development of the system is suggested.

Energy Structure

Biomass energy is one of the most important renewable energy sources. Full utilization of this energy helps to optimize agricultural development, improve our living environment, and replace some non-renewable energy sources, thereby promoting the eco-environment across the country. However, biomass energy has not been extensively utilized in rural areas of China. Many farmers are not very enthusiastic about the use of biomass energy. Many scholars have tried to boost the willingness of farmers to utilize biomass energy. Therefore, this paper collects the relevant data from six aspects, namely, environmental factor, cost factor, income factor, behavior factor, policy factor, and personal factor, and constructs a binary logistic regression model. On this basis, the driving and influencing factors of biomass energy utilization were empirically analyzed from the perspective of farmers. The results show that the development of biomass energy is mainly affected by the farmers’ awareness of national energy strategy, the relevant costs of biomass utilization, and the attitude of family members and village committee. The research provides an important reference for further promotion of biomass energy, elevation of its utilization efficiency, and optimization of energy structure in rural China.

Environmental Consequences

Every type of energy utilization for electricity generation has environmental consequences. The main consequences of burning fossil fuels and of nuclear power are well-known. Renewable energy sources (wind, solar, biomass, hydroelectric, geothermal, etc.) are generally thought of as harmless, but this doesn’t mean they have no environmental consequences at all. Most of them have a significant aesthetic impact and require large areas of land. Some also have a significant impact on the eco-system (birds, fishes, etc.). This paper summarizes the environmental issues caused by all kinds of renewable energy sources.

The main focus of the paper is the investigation of the social potential of local renewable energy utilization in a rural peripheral region in Hungary. Public acceptance of biomass-based renewable energy sources can be crucial for rural communities in realization of their sustainable development strategy. The research area was Koppany Valley Natur Park 2000, a microregion of 10 settlements located in the South Transdanubian region. This microregion is characterized by poor and depressive socioeconomic and demographical conditions, despite its significant natural resources. The microregion’s complex development strategy includes the utilization of local resources of renewable energy. Local population survey (n = 310) was conducted (in May 2018) on local biomass potential, knowledge, and attitudes of the local stakeholders in the microregion. Multinomial logistic regression model estimates the acceptance of population, explanatory variables are categorical demographical (personal) factors and specific factors (based on answers of respondents). Trust in local authorities, knowledge on biomass in general and on specific technologies, as well as the education level of rural inhabitants are significant factors in supporting biomass plant establishment. Further, the group and characteristics of acceptance groups that the local development strategy may consider were defined.
