Abstract
Marine renewable energy (MRE), including offshore wind, tidal, wave, thermal, and biomass resources, can support decarbonization while advancing blue economy objectives, but its deployment requires coordinated ecological, technical, and social strategies. This study synthesizes the interdisciplinary nexus among marine science, blue economy, energy analytics, and sustainability education, and maps the research development using a PRISMA-guided bibliometric review of Scopus-indexed literature. Bibliometric indicators (publications, cita tions, and collaboration networks) were analysed in order to map research development trends. Findings indicate a rapid growth in MRE research with strong international collaborations, mainly led by offshore wind and tidal technologies, together with persistent concerns related to habitat disturbance, biodiversity impacts, and spatial conflicts. Energy analytics (forecasting, optimization, and grid integration) emerges as key enabler for managing variability and improving system reliability, while sustainability education supports the public understanding, social acceptance, and development of workforce capacity. Accelerating sustainable MRE adoption requires marine spatial planning, robust environmental safeguards, and data-driven grid and system management aligned with equitable governance of blue economy.
