A new path of economic development among emerging and developing nations has a distinct impact on the environment than seen in the past. The current study attempts to examine how these growth patterns in the developing world have impacted the degradation of the environment. This study contends that merely considering GDP per capita and the proportion of manufacturing in GDP fails to encapsulate the complete growth dynamics of developing and emerging countries. Consequently, such an approach does not adequately reflect the impacts of environmental degradation. As a result, the economic complexity index (ECI) is introduced to the model to reflect the full effects of new growth trajectories on CO2 emissions by using the Panel Fully Modified OLS (PFMOLS) model of 67 emerging and developing countries during 1996–2020. The results indicate that the complexity of developing and emerging economies, on the one hand, raises CO2 emissions, likely through expanding economic activities (the scale effect). Moreover, ECI reduces CO2 emissions by moving the economy toward more high-tech and environmentally friendly technologies and industries and favorable changes in the energy mix (the efficiency effect). Overall, the empirical outcomes emphasize that the final impact of ECI on the environment was negative in most samples, indicating an improving impact of economic complexity on environmental degradation, reflecting that the “efficiency effect” outweighed the “scale effect.” The findings imply that technology and knowledge transfer are essential for energy efficiency and sustainability.

In light of global challenges such as the war in Ukraine and the depletion of fossil fuel resources, it is essential to explore sustainable energy solutions. Hybrid energy systems represent a potential solution, offering energy independence to urban housing estates and reducing CO2 emissions. This article aims to explore the feasibility of integrating photovoltaic systems (utilizing vacuum collectors) and combined utilities (system heat and electricity) in a hybrid setup, leveraging existing technical infrastructure with necessary modifications. A key aspect is to perform calculations on the amount of heat and electricity generated from these systems. The study analyzes the demand for heat and electricity among consumers compared to the estimated production from renewable sources. Calculations also include the potential energy savings and CO2 emission reductions achievable through the proposed solutions. The findings indicate that hybrid photovoltaic systems with heat storage could effectively address energy issues in urban housing estates, given adequate support and community involvement. The innovative methodology employed in this study encompasses both analytical and experimental research approaches. The analysis employs advanced statistical techniques and data integration to enhance understanding of the phenomena studied, while the experimental research provides robust results through controlled variable manipulation and precise measurement tools, thereby verifying the study’s objectives.

The current challenges in the energy crisis, triggered primarily by the Russo-Ukrainian conflict, have had an unprecedented impact on investment in the energy market [...]

Security and competitiveness are two very important aspects of the economic and political development of every country. In the 21st century, one of the key drivers of most economies in countries throughout the world is energy. Different countries adopt different measures so as to ensure their security and competitiveness through the effective energy policies that make traditional and renewable resources adequately available hence eliminating the possibilities of shortages. Our paper takes up the case study of Germany as one of the wealthiest and most developed economies in the European Union which also occupies the first positions in the charts of energy uptake and consumption. German policy-makers realize its vulnerability when it comes to energy security and attempt to diversify its energy competitiveness using the renewable sources of energy (for instance via the adoption of the Erneuerbare-Energien-Gesetz or the "Renewable Energy Act" (EEG)). We analyze the issues of energy security and competitiveness of a country using an example of Germany. Moreover, we describe what challenges the renewable energy sources (RES) might bring into the conventional game and how this might influence the competitiveness and security.

In autumn 2021, the world faced the first round of energy crisis [...]

AbstractThe study examines the long‐run relationship between renewable energy consumption and economic growth within the framework of the traditional production function in 29 European countries from 1995 to 2016. The study was based on the panel unit root tests, panel cointegration test—the Kao (1999), Pedroni (1999, 2004), Westerlund (2005) and fully modified ordinary least squares estimator and dynamic ordinary least squares estimator. The study found that there is a long‐term equilibrium relationship between economic growth and renewable energy consumption and that renewable energy consumption has a positive impact on economic growth. The results suggest that the use of renewable energy as a global commodity in the process of economic growth is highly significant. Therefore, policies to promote renewables can provide for economic growth, an increase in renewables and the reduction of greenhouse gas (GHG) emissions, and ensure important sustainable development goals.

The constantly growing demand for energy, the need to ensure the security of its supply, and the progressing climate changes related to the emission of carbon dioxide and other pollutants have caused, in recent years, an increase in interest in offshore wind energy. This paper presents all the work that needs to be done to build a wind farm in the Baltic Sea. The work focuses on the description of the equipment and the necessary tests to perform in order to analyze the obtained data. The data will allow for unambiguous interpretation and the selection of a convenient location for the construction of a wind farm. The final product of the work is a cost estimate, in which the costs of undertaking such an undertaking are shown.

Successful achievement of the 17 Sustainable Development Goals (SDGs), including SDG 7: Affordable and Clean Energy, is impossible without proper financial support, especially after the devastating impact of the COVID-19 pandemic. Despite more than million academic papers related to SDG 7, only very few of them address the financial aspects of achieving SDG 7. To test the hypothesis, “SDG 7 related academic studies ignore the issue of investment in general and responsible investment in particular”, a meta-analysis is performed that includes a number of specific instruments and technics such as SciVal by Elsevier, VosViewer, Google trends, Google Books Ngram Viewer and Google Data. The results show a lack of appropriate academic support (methodology, empirical results, econometric models etc.) for practitioners to fill the existing financial gap and successfully achieve SDG 7. Among 1.2 million SDG 7 related papers, less than 100 deal with the financial gap problem measured by trillions of dollars in achieving SDG 7. This paper identifies the most promising and relevant topics for study related to SDG 7 and investment: the impact of the pandemic on decisions in the energy sector; efficiency of SDG 7 investment support and methodology for its assessment; green bonds, green loans, sovereign green bonds as responsible investment tools to advance SDG 7.

The article aims to identify the latest trends in research on renewable energy, sustainability and the environment. A total of 92,873 publications from 123 Scopus sources for 2020–2021 are compared using the scoping review method. The results show that the most cited works in this sample are those by authors from the Asian region. The research of these authors focuses on the security, efficiency and reliability of separate elements in energy systems. Besides, the paper considers the problems regarding COVID disease along with the renewable energy sources, perovskite and organic solar panels, nanostructured materials and high energy density. Finally, the paper analyses applications of computer science methods in research on renewable energy, sustainability and the environment. The findings evidently show that recent advancements in computer science methods were not extensively used in the discussed research domain and give a great room for novel strategies of prognosing, simulation and processes optimisation.
