With the global demand for virtually zero greenhouse gas emissions by 2050, science and technology are facing major challenges as to how to tackle this challenge. Even under these circumstances, building a bright future while achieving sustainable growth can be said to be the greatest challenge required for future science and technology.

In order to realize such a society, research and development within the academic system that has been vertically divided up to now cannot cope with it. In other words, it is essential to establish an innovative theoretical system that can cross different energy conversion engineering systems of electrical system, mechanical dynamical system, and thermal energy system. For more than 50 years, our research group has been the first in the world to show that energy system analysis can be unified with circuit theory as a common analysis structure even between different engineering systems.

So far, by applying this theory and conducting a lot of basic research that is the basis of equipment development, we have developed concrete heat energy systems such as heat pumps and have obtained many results. .. In the future, the scope of application will be further expanded to optimize the energy supply network consisting of various energy forms such as "hydrogen energy supply chain", "local energy", and "renewable energy", and to realize decarbonization. Our research on the future energy society by realizing the optimization of energy consumption in "living space", "production technology", and "agricultural food management" as the demand side and developing a concrete system. I will present it to the world from the room.

By 2050, there are only 30 years left. It is an era when you are the center of society. It is up to you to create a bright future society.
