Sri Lanka is an island country in the Indian Ocean with roughly 1,340 km-long coastlines. The nation has considerable potential for ocean energy production due to its geographic location. By analyzing the many forms of ocean energy sources accessible, such as wave, tidal, and ocean current energy, this article seeks to offer an overview of the ocean energy potential in Sri Lanka. According to the report, Sri Lanka has enormous potential for developing ocean energy, notably in wave and tidal energy. High upfront expenditures and the absence of supporting laws and regulatory frameworks, however, provide serious obstacles to the sector’s expansion. Nevertheless, the country’s commitment to renewable energy and its efforts to establish a conducive policy environment is expected to facilitate ocean energy development in the coming years.
