Natural energy utilization was discussed for Sustainable Marine City (SuMaC) which is a fictitious island (800-900 ha) on Osaka bay coastal zone. In SuMaC, electricity demand is presumed 59.8 × 10^6 kWh/year. Potentials of natural energy such as photovoltaic power, wind power, tidal power, and wave activated power and recycle energy such as biogas power and refuse-burning power were evaluated considering weather conditions and the land use plan of SuMaC. The results suggest that electricity are supplied at 150% for the demands. However, in nature of natural energy, it was also suggested that the energy supply showed considerable time-lag against the demand. To solve the problem, establishment of total and zonal energy control centers was proposed for efficient energy storage and conversion in SuMaC.
