In this research, aligned with global policies aimed at reducing CO2 emissions from traditional power plants, we developed a holistic energy system utilizing solar, wind, and ocean thermal sources, tailored to regions optimal for conversion (OTEC). The selected site, characterized by favorable wind solar conditions close areas high OTEC potential, is designed meet the electricity needs of coastal community. system's core components include an Organic Rankine Cycle, turbines, thermoelectric elements, pumps, heat exchanger, turbine, collector. A detailed analysis thermodynamic evaluation based on principles were carried out using Engineering Equation Solver (EES) software. Key factors such as speed, radiation, collector area critical in determining performance. To enhance effectiveness, conducted comprehensive comparison optimization algorithms, incorporating Non-dominated Sorting Genetic Algorithm-II (NSGA-II) Pareto front value optimization. This approach significantly outperformed other algorithms Particle Swarm Optimization (PSO), Algorithm (GA), Simulated Annealing (SA) terms efficiency cost-effectiveness. achieved exergy 14.46 % cost rate $74.98 per hour, demonstrating its suitability intended functions. Moreover, exergoenvironmental was proposed plant. findings revealed that key component HEX has factor due their use hot water, which zero unit impact. Additionally, pumps demonstrated impact factor, indicating negligible component-related environmental impacts. Sensitivity further evaluated performance parameters, revealing increases irradiation lead decreased total rates, while higher turbine temperatures resulted remarkable 14.08 reduction rate. These results underscore economic viability operating strengthen argument adoption financial perspective.
