Concern about global warming calls for an advanced approach for designing an energy system to reduce carbon emissions as
well as to secure energy security for each country. Conventional energy systems tend to introduce different technologies with
high conversion efficiency, leading to a higher average efficiency. Advanced energy systems can be achieved not by an aggre-
gate form of conversion technologies but by an innovative system design itself. The concept of LCS (low carbon society) is a
unique approach having multi-dimensional considerations such as social, economic and environmental dimensions. The LCS
aims at an extensive restructuring of worldwide energy supply/work system by not only replacing the conventional
parts with the new ones, but also integrating all the ponents and designing absolutely different works.
As a core tool for the LCS design, energy-economic models are applied to show fe
