Wind Turbine Research Map: An Overview of Renewable Energy Technology Innovation Trends

The purpose of this study is to identify current research trends in wind turbine technology and explore emerging innovations in the field of renewable energy based on the wind turbine research map. The research method of this study is the Bibliometric-Systematic Literature Review (B-SLR) which includes a 10-step process. The B-SLR framework emphasizes critical analysis, timeliness, comprehensive coverage, methodological rigor, coherence, and originality of contributions, with a focus on creating new and relevant theoretical insights. Bibliometric analysis is obtained using Vosviewer software to determine the mapping of trends, patterns, and gaps for further research related to wind turbines. Based on the Google Scholar database through data collection using POP (Publish or Perish). This study systematically reviews 730 scientific articles related to wind turbine innovation from 2015–2025, producing a wind turbine research map obtained by five main research clusters, namely energy production, industrial policy, turbine component design, control innovation, and future trends. The dominant topics are wind turbine blades, China, and power generation. The research progresses from a policy focus (2016–2018) to technical innovation and sustainability (2020–2022). The analysis reveals wind turbine research areas are blade design, offshore operations, and new materials, while themes such as alternative energy and emerging markets remain under-explored. These results reveal significant opportunities for technological innovation and cross-disciplinary exploration in renewable energy.
