Clean Energy Initiatives and Global Sustainability: A Bibliometric Study

Abstract

In the pursuit of global sustainability in energy production, green projects centered on clean energy have emerged as an international priority. These initiatives aim to address the pressing challenges of climate change, environmental degradation, and the depletion of finite energy resources. By focusing on renewable and clean energy sources such as solar, wind, hydro, and sustainable biomass, these projects seek to reduce greenhouse gas emissions, enhance energy efficiency, and promote long-term environmental and economic sustainability. The global emphasis on clean energy reflects a collective commitment to transitioning from fossil fuel dependency to greener, more sustainable energy systems. This transition not only helps mitigate the adverse effects of climate change but also fosters innovation, creates green jobs, and supports energy independence. As governments, international organizations, and private sectors increasingly align their efforts, clean energy projects are becoming key drivers in the global move toward sustainable development. To understand the current trends in the field of sustainable energy, this bibliometric study was conducted. By analysing scientific publications, the study identifies key lines of research in green projects focused on clean energy. Using data from the Scopus database, the study examines trends spanning the period from 2002 to 2022. The bibliometric analysis provides insights into the evolution of research priorities, highlighting the growing global interest in clean energy as a critical area of focus for achieving sustainability goals. This period captures the gradual shift from conventional energy systems to innovative green solutions, reflecting advancements in technology, policy changes, and increasing environmental awareness. The findings from this analysis offer a comprehensive understanding of the research landscape, guiding future studies and policy directions in sustainable energy development. The bibliometric analysis reveals that China leads in scientific productivity in the field of sustainable energy during the period analysed, followed by India and the United States. Among the most prolific journals contributing to this discourse are the Journal of Cleaner Production and Resources Policy, while prominent institutions such as IBN Tofail University and WSB University have emerged as key contributors. Additionally, the analysis identifies Taghizadeh-Hesary and Yoshino as leading authors in this area of research. Key themes dominating the discourse include keywords like “sustainable development,” “renewable energy,” “green projects,” “renewable energy resources,” “global warming,” and “landfill.” These keywords reflect a global emphasis on addressing environmental challenges through sustainable energy solutions and innovative green technologies. The findings highlight the pivotal role of academic and scientific contributions in shaping the transition to cleaner energy systems. This research serves as a valuable resource for stakeholders, including researchers, policymakers, green technology investors, and project managers. By identifying leading contributors, trends, and focus areas, the study provides a roadmap for future initiatives aimed at fostering an effective energy transition on a global scale. These insights can guide the formulation of strategies that support sustainability, innovation, and collaborative efforts in the field of renewable energy.
