Trend Assessment and Comparison of Primary Renewable Energy Consumption in the European Union and India: Possibilities after Covid-19 and War Rani Bhagat, Priya; Naz, Farheen; Magda, Robert This paper is an attempt to bring attention to the ways in which global renewable energy consumption has been transforming, by the recent shocks in the energy markets caused by the covid-19 pandemic and the war in Ukraine. Evaluating global trends would require a much more extensive study, yet this article attempts to make empirical conclusions, by observing the trend in percentage changes in unconventional energy consumption time series data, collected over the span of 10 years from the European Union and India. A trend analysis of these characteristics can be useful in making informed predictions for formulating renewable energy policies, to reduce interdependency on other countries, supply chains and political instabilities. The comparison between the European Union and India is justified on the grounds of size and their similar dependency on neighboring superpowers for fulfilling domestic energy needs. In conclusion, this study proposes to focus on the untapped potential of the EU-India relationship and to mutually strengthen their position in Europe and Asia. India has an abundance of non-renewables and the potential for generating renewable energy, which the EU can tap into, via new energy trade agreements. In exchange, the EU has the expertise and technical resources to provide backing to the energy initiatives of India.

Investigating the “Resource Curse” in China: Is it Sufficient to use the Usual Methods? Heimné Rácz, Éva; Bolla, Szilárd; Kovács, Norbert; Kazinczy, Eszter; Völgyi, Katalin; Hossain, Kamal; Hu, Jim; Lukács, Eszter Our article on the study of the “Resource Curse” in Chinese provinces, was written with two objectives. First, by reviewing the international and Chinese literature and analyzing the economic development of the relevant Chinese provinces, we sought to explore whether the resource curse phenomenon exists or can be demonstrated. And second, we want to draw the reader's attention to the fact that Chinese and Asian economies in general have central planning models, the main purpose of which is to define and focus on national economic development priorities. The sub-divisions of the central development plans include development targets for each region, which naturally take into account the economic performance of each province and the factors that determine it. It follows from the latter line of thinking that the economic development of the four Chinese provinces concerned (Gansu, Guizhou, Qinghai and Shanxi) cannot be interpreted in a 'piecemeal' way, based solely on the existence or otherwise of the resource curse phenomenon. In writing this article, we also wish to draw attention to this holistic, comprehensive Chinese (Asian) way of thinking.

Energy Transition in Power, Heating and Transport Sectors, based on the Majority of RES and Energy Storage Azzopardi, Brian; Pinczynski, Marcin; Kasperowicz, Rafał; Bilan, Yuriy The world is facing problems that are related to climate change and pollution, which are partially caused by the emission of toxic compounds and CO2, from the combustion of fossil fuels. The natural resource of fossil fuels, have been exploited for many years, such resources have also been depleted dramatically. The above-mentioned facts determine the need to conduct research that will demonstrate the technological and socio-economical possibilities of transforming energy systems and parts of transport systems from fossil fuels to renewable energy. This paper presents the idea of supplying a selected region, 100% with RES, accounting for costs and environmental efficiencies, for the entire energy system. Further, the analysis of the subject indicated a need to conduct research on correlations derived from integrating collective heating, transport systems with high V2G energy storage capacity and power systems, in order to optimize the functioning of the entire energy market. Furthermore, the above considerations suggest that there is a need to propose a new model for electrical systems, different than the one based on the classical concept of producer- recipient. This research was carried out through a combination of quantitative and qualitative methods. The quantitative analysis applied agent-based modelling; A method supported by extensive qualitative research. The conducted research indicates that renewable energy systems demonstrate greater cost and environmental competitiveness, than conventional energy systems. Furthermore, it has been shown that the integration of collective heating and transport systems, with the energy system has a positive impact on the efficiency of the entire system, by reducing primary energy demand and decreasing carbon dioxide emissions. Finally, the conducted research revealed that the reduction of energy demand, has a positive effect on the transformation of a conventional energy system, into a RES system.

Food Security of Tunisia: Comprehensive Analysis of a Composite Index Abdallah, Marwa Ben; Fekete Farkas, Maria; Vasa, László; Lakner, Zoltán For decades, food security has been the main concern of a large number of researchers. With the emerging of the COVID-19 pandemic, growing research that try to measure the food security status. Different studies have attempted various measurement methods aiming to quantify the level of food insecurity for some countries. Seventeen indicators have been selected to build a unique food security index. Principal Component Analysis (PCA) method has been employed to determine a comprehensive evaluation of index. 2 factors have been resulted to comprehend the food security index movement based on yearly indicators. Furthermore, the econometric model, Vector Error Correction Model (VECM) has been employed to detect the relationship between the built food security index and macroeconomic indicators. a long run causality relationship has been identified between the food security index, exchange rate, GDP, and global food price index. The resulted food security index is positively affected by the food price and there is an adjustment of 42.7% annually of the food security disequilibrium.
