Marine renewable energy harnessing for sustainable development in Bangladesh: A technological review

A strategy for promoting ethical use of ocean resources while preserving the marine environment is known as the blue economy. The Blue Econ- omy's foundational element, marine renewable energy (MRE), has enormous potential to generate clean energy, spur economic growth, and slow global warming. Bangladesh has a lot of potential for the development of MRE due to its wide coastline and maritime resources. From a Blue Economy viewpoint, this review article offers a thorough examination of the present trends, opportunities, and difficulties associated with MRE implementation in Bangladesh's coastal region. The potential of MRE technologies, such as tidal energy, wave energy, wind energy, and ocean thermal energy conversion (OTEC), to deliver clean, dependable, and affordable energy while generat- ing new business opportunities for coastal towns has been examined in this article. The paper also evaluates Bangladesh's legal and policy frameworks for MRE development, as well as the funding alternatives, investment op- portunities, and socioeconomic and environmental effects of MRE projects. The paper emphasizes the importance of employing sustainable and ethical development methods to guarantee that MRE development adheres to the objectives of the Blue Economy. Overall, this review paper offers a road map for Bangladesh's MRE sector's sustainable and inclusive growth, addressing several Sustainable Development Goals (SDGs) in Bangladesh, ranging from clean energy access to climate action, economic growth, and environmental sustainability. It is hoped that it will add to the ongoing discussion on the nation's sustainable energy development.
