Since the present hierarchical grid structure and AC interface are so mature and too rigid, a new electric power system architecture is proposed here to save the Earth with renewable energy sources.The architecture consists of a new concept and a historical technology. That is network of many “electric power clusters” with DC interface. The cluster includes dispersed electric power generations, electric appliances, electric storage and “electric power router”. The router is equipment to resourcefully route electrical energy between such neighboring clusters and to manage electrical energy in the cluster. The transactions of electrical energy (inter clusters and/or intra cluster) and electric generations from renewal energy sources (like sun shine, wind, tide and bio gas) are intermittent and have very wide dynamic range, so, the interface must be by DC. When we achieve the energy society with the architecture, we will be able to reduce energy consumption, greenhouse gas and materials.
