The invention provides a novel energy island system, and belongs to the technical field of green energy application. The novel energy island system comprises renewable energy resources, a power system, a heat supply system, a cooling system and a pollutant purification and waste centralized disposal system. The geothermal energy passes through a heat pump and then enters the heat supply system. The power system converts the renewable energy resources into the electric energy and the heat energy. One part of the electric energy which is formed by conversion is used for achieving power supply inthe region, and the rest of the electric energy enters an energy grading device. The energy which is graded by the energy grading device is used for being provided for the cooling system and the heatsupply system. Sludge and the waste in the region are conveyed to the pollutant purification and waste centralized disposal system to be purified, and the pollutant purification and waste centralizeddisposal system generates the electric energy and the heat energy in the purifying process. The electric energy and the waste heat generated in the purifying process enter the energy grading device.The novel energy island system solves the problems that the existing urban energy utilization rate is low, and the waste is difficult to dispose, and can be applied to large industrial parks and urbanenergy utilization.
