For the purpose of developing the future innovative energy technology, the paper described a strategic point of view. Effects of the energy issue are remarkable on the next generation and thereafter as seen in the finite of energy resource, global-scale environmental changes, the increasing energy demand, natural/social influences of large-scale technology development. If the technological development is going on in the same way as until now, there will appear limits. Relating to the strategies, to seek what energy should be among the strategies, it is necessary to consider not only global-scale problems but particular conditions in Japan (self-sufficiency, international cooperation, creativity, etc.) Also, wisdom and technique are necessary to attain it. Technological development in a wide sense plays a major role in the energy strategy. Technology innovation must be advanced according to the energy strategy. Integrating ideology into the development of energy technology and selecting therefrom developmental subjects which meet the purpose, required is the construction of the energy system with high flexibility and functionality. Looking at the conventional way of thinking from a different angle and posing a future pull plan, Japan should show leadership to the world. 20 refs., 25 figs., 8 tabs.
