We proposed "Energy chain" methodology as an effective evaluation tool for total energy system using electricity form grid and Co-generations. The energy chain concept is defined as energy flow from source to energy consumption to final end use energy benefit in terms of heating, cooling, lighting and other benefits of energy. Two indices are proposed to measure the effectiveness of this process. The first of these is the Energy chain joule index (ECJI) which expresses the extent of energy conservation. The second is the Energy chain carbon index (ECCI) which expresses the extent of greenhouse abatement. In future, this concept and evaluation methodology is made public both internationally and domestically. And, an analysis tool using this methodology will be developed and a lot of evaluations examples will be accumulate by using the tool.
