Outline of Final Research Achievements

The purpose of this study was to analyze the effects of introducing next-generation energy systems on the energy efficiency of the society, using exergy indices that take energy "quality" into account. Specifically, in this study, exergy was defined in an input-output table; an exergy consumption database, which corresponded to the input-output table, was constructed; and a case study, which targeted renewable energy power generation, was conducted. Hence, the exergy consumptions that were directly and indirectly generated in each industry were estimated, and the exergy balance of the renewable energy power generation throughout the lifecycle was shown. This quantitatively demonstrated the effectiveness of using renewable energy in low "quality" energy demand and next-generation technologies with high power consumption.

Academic Significance and Societal Importance of the Research Achievements

本研究は、産業のエネルギー需要別(冷暖房、給湯、動力など)、エネルギー供給別(電力、ガス、化石燃料など)にエネルギーの需給量を推計し、エネルギーの「質」を考慮することが可能なエクセルギー消費量に変換することで、産業間のエクセルギーフローを体系的に整理した。また、このエクセルギー指標を産業連関表と組み合わせることで、サプライチェーン全体で直接間接的に消費されるエクセルギー消費量の分析評価が可能となった。この成果は、エクセルギー消費量が大きい産業部門の特定につながり、産業の電化や再生可能エネルギー技術の導入など技術選択に資する情報となりうる。
