Abstract
Marine fuels and renewable energy sources are critical in lowering carbon emissions and encouraging sustainable maritime practices. Their implementation promotes a more environmentally friendly and cleaner future for marine transportation. Effective decision-making is critical in the context of marine fuels and green energy for attaining sustainable energy management and progressing towards a greener and more ecologically friendly future. This research article emphasizes the importance of thoroughly assessing various energy options and their potential impacts on the atmosphere, economy, and society. It acknowledges the significance of incorporating renewable energy bases, energy efficiency processes, and greenhouse gas emission reductions into decision-making processes. This article presents optimal decision-making methodologies to meet the complexity of decision-making in this domain, which contains uncertainty and trade-offs. It investigates diverse decision-making frameworks, approaches for uncertainty analysis, and techniques for multi-objective optimization, stakeholder engagement strategies, and policy development concerns in sustainable energy management. Case studies from the real world are investigated to discover both effective and bad decision-making practices. These evaluations produce valuable insights for policymakers, energy managers, as well as stakeholders, allowing them to make successful decisions. We can expedite the adoption of clean energy solutions, reduce dependency on fossil fuels, alleviate the impacts of climate change as well as support the creation of a sustainable as well as strong energy system for present and future generations by incorporating the findings into decision-making processes.
