Abstract: Renewable energy systems have much lower environmental impact than conventional energy technologies. Tidal energy is one of the most important forms of renewables which carry the electricity production capacity within its height differences and current flow. In this paper, a time-dependent mathematical model for green energy generation from a single-pool tidal system is developed. Using current model with available tidal data, the extracted energy from this system can be calculated. Model results have shown that such system has the capacity of producing 40.6 Megawatts electricity from tidal energy for a specific area.
