This paper concentrates on the study of Dongtan Eco-city in Shanghai, aiming to put forward improvement suggestions about the renewable electricity application system. The study includes the calculation of the total energy consumption from the buildings, and the amount of energy generated from potential renewable energy technologies that might be applied in the near future. For the calculation of the total energy consumption, the assumption of a typical 3-storey attached dwelling with the total area of 102 m2 is made. TAS simulation software is applied to estimate the heating and cooling load of the dwelling. All of the 27,000 dwellings in the city have the total load of 4560.7 MWh/year. Based on the monitoring results of BedZED project, the total energy demand in all types of buildings of 236 GWh is figured out. Generally, it is suggested that renewable energy contributes to generating 291 GWh based on the proposed design. The total area of 1,452,600 m2 thin- film BIPV using new technology with high efficiency of 20% creates solar energy of 70,995 MWh, covering 30.1% of the energy demand the twenty- four 1.5 MW wind turbines produce wind energy of 36,792 MWh which offsets 14.5% of the demand and a biomass-CHP plant with the peak load of 30 MW heat energy and 8 MW electricity generate heat energy of 147,000 MWh and the electricity of 39,200 MWh, covering 55.4% of the demand in total, and meanwhile selling the remaining 55,500 MWh of energy to the national grid, providing the benefits of £3,330,000. Carbon Savings is one of the benefits from using renewable energy. Solar energy, wind energy and biomass energy contributes to reducing 32,658 tC02, 17,007 tC02, and 62,132 tC02 per year respectively.
