This paper describes on new solutions for energy issues and town development. The new social system instead of the conventional energy supply system has been discussed. The renewable energy is eagerly expected but the electrical output is too unstable to use. In this situation, the new system with three functions was proposed in 2004. The first is to provide the best circumference to use the renewable energy. The electricity is exchanged between grid and demand-side with distributed generation, heat storage and electric battery. The second is to provide the visualization tool to cooperate with citizens. The advanced demand-side control promotes the energy saving and accepts the fluctuating output of renewable energy. The third is to provide the electricity from ships or EV at the emergency. The system contributes to the early recovery in the case of anticipated disaster. With these, a strong town based on the renewable energy can be realized. In addition, it has a possibility that visualization of electricity demand can be used to detect the abnormal condition or sudden illness of elderly person who lives alone in a house. These technologies, with combined information and mobility, are important to develop the future safety and saving energy town.
