Abstract
Ocean energy represents a vast and untapped resource with the potential to play a pivotal role in the transition to a sustainable energy future. This chapter examines the advancements in harnessing tidal currents and wave dynamics as renewable energy sources, supported by real-life data and case studies. Cutting-edge technologies such as tidal stream turbines and wave energy converters are showcased, alongside their transformative impact on energy generation. Drawing from operational projects and research initiatives, we provide empirical evidence of the feasibility and scalability of ocean energy. Case studies demonstrate the successful deployment of tidal energy systems and the promising performance of wave energy converters in diverse marine environments. These real-life examples underscore the growing momentum and practicality of ocean energy solutions. Furthermore, we analyze the socioeconomic and environmental implications of ocean energy exploitation, offering a balanced perspective on its opportunities and challenges. Data-driven insights inform discussions on job creation, energy security, and emissions reduction potential, as well as considerations related to technology optimization and regulatory frameworks. By presenting a comprehensive overview of ocean energy advancements supported by empirical evidence, this chapter aims to inform policymakers, researchers, and industry stakeholders seeking to accelerate the adoption of sustainable energy solutions. Our vision is one of a future where the vast potential of ocean energy is fully realized, contributing significantly to global efforts to combat climate change and achieve energy sustainability.
