Energy Chain - A New Concept in Evaluating Future Energy Conservation and Greenhouse Abatement Alternatives and Effectiveness -

概要 （図表や脚注は「報告書全文」に掲載しております）

どのようなエネルギーシステムが省エネや省CO2になるのか、関係する業界・技術・学会が多岐にわたっているため、混乱が生じている。そこで、エネルギー資源の採掘から「最終エネルギー負荷」までのエネルギーの流れを「エネルギーチェーン」と捉え、民生用を中心に、系統電力システムや分散型エネルギーシステムなどのエネルギーチェーンに関し、「最終エネルギー負荷」に基づいて、システムの違いに関わらず、客観的に評価できる手法の提案を行う。

概要 （英文）

Throughout the world, the need for both energy conservation and greenhouse abatement is becoming more important. Japan is a major contributor to research and development for these energy saving technologies.Critical review is always necessary to ensure that prospective technologies are really energy saving and contribute to greenhouse abatement over the whole spectrum from producing the energy through transmission, utilization and end use. The "Energy Chain" methodology is proposed as an effective evaluation tool for this purpose.The energy chain concept is defined as energy flow from source to "end use energy benefit" in terms of heating/cooling, hot water, lighting and other benefits of energy through final energy consumption.Two indices are proposed to measure the effectiveness of this process. The first of these is the Energy Chain Joule Index (ECJI) that expresses the extent of energy conservation. The second is the Energy Chain Carbon Index (ECCI) that expresses the extent of greenhouse abatement. The inputs and outputs from prospective technologies are subjected to these indices to result in measures of energy conservation and greenhouse abatement for comparison with other processes. The paper will explain these concepts in some detail and provide examples of their use in comparing the relative effectiveness of different energy saving and greenhouse abatement technologies.The "Energy Chain" concept can be used to ensure effective energy conservation and greenhouse abatement using appropriate technologies developed from active research and development.
