The energy problems of our country including CO₂ reduction and the procurement of energy resources etc. are difficult to solve by the improvement of the conventional supply and demand systems. As a method to solve these problems, it is necessary to build the new systems that are combined with energy conservation and expansion of the renewable energy. Specifically, we are researching to construct novel future energy systems which are integrated with energy creation and two-way systems. In this study, our aim is the optimization (energy and economic efficiency) from generation to consumption, through the use of theory of constraints based on the each energy conversion between various energy forms such as heat, electricity, mechanical power, etc.

Energy creation: Consumption of the fossil fuels can be reduced by achieving effective utilization of energy at factories or the power plants and expanding of renewable energy.

Two-way systems: Procurement of energy resources, management of supply & demand (adjustment and leveling of load fluctuations), and storage and transportation of energy are performed through the use of vehicles.

As past results of research, it is clarified that CO₂ emissions (fossil fuel) from a steel-works and a home (house including privately-owned cars) are reduced economically more than 30% and more than 75% each.
