Abstract
As the global population grows, the demand for energy rises, leading to increased reliance on fossil fuels that harm the environment through COx and NOx emissions. These emissions contribute to accelerated climate change, acid rain, and global warming. This paper presents a comprehensive bibliometric analysis of renewable energy harnessed from ocean waves, utilizing data from the Scopus database, spanning 1979 to 2021, covering 619 papers. The analysis, conducted with bibliometric methods and visualized using VOSviewer and Tableau, provides insights into the development of ocean wave energy as a renewable resource. The analysis reveals a significant increase in publications on ocean wave energy over the last decade, peaking with 82 publications in 2021 and 1596 citations in 2011. A keyword co-occurrence network illustrates the evolution of key research topics, primarily focused on developing efficient and flexible technologies for utilizing ocean waves as a renewable energy source. The UK leads in international collaboration, while the USA ranks as the most prolific publisher of research on ocean wave energy. This paper serves as a guide for researchers to understand the evolution of ocean wave energy research from a bibliometric perspective, encouraging the development of environmentally friendly, waste-free, and cost-effective technologies.
