This study aims to design energy supply systems from various energy sources for transportation sectors and comparatively analyze the life cycle cost of different scenario-based systems. For components of the proposed energy supply system, we consider a typical oil refinery, byproduct hydrogen system, renewable energy source (RES)-based electric generation system and existing electricity grid. We also include three types of vehicles in transportation sector such as internal combustion engine vehicle (ICEV), electric vehicle (EV), fuel cell vehicle (FCV). We then develop various energy supply scenarios which consist of such components and evaluate the economic performance of different systems from the viewpoint of life cycle cost. Finally we illustrate the applicability of the proposed framework by conducting the design problem of energy supply systems of Jeju, Korea. As the results of life cycle cost analysis, EV fueled by electricity from grid is the most economically feasible. In addition, we identify key parameters to contribute the total life cycle cost such as fuel cost, vehicle cost, infra cost and maintenance cost using sensitivity analysis.

Regarding climate change, the most significant challenge the world faces is achieving the goal of stabilizing the global concentration of greenhouse gases. However, this cannot be accomplished by greenhouse gas reduction efforts of developed countries alone. In this context, a "sectoral approach" has been brought up as a way to overcome the limit of the Kyoto Protocol and induce the participation of developing countries. This paper focuses on the different types of sectoral approaches that have been suggested so far, and their criteria, scope and effectiveness. It therefore explores the potential each approach has as a policy alternative under the post-2012 scheme. On top of that, with the possibility of these sectoral approaches becoming strong future policy alternatives in mind, this paper also analyzes their applicability to the Korean industry. For the steel, petrochemical and oil industries - in which energy efficiency exceeds the world average- a technology-based approach is proposed as an alternative. For the cement, paper and power generation industries - in which energy efficiency is about the same as the global average - a sectoral crediting mechanism or an index-based approach or a sector-wide transnational approach are proposed as alternatives. Lastly, this paper suggests a future research direction for their adoption and implementation.

지구 온난화 대책의 일환으로 추진되고 있는 전통조명의 LED화 교체정책은 엄청난 비즈니스 기회를 몰고 왔다. 이는 에너지 수요 측면에서 유일하게 주목받고 있는 분야가 바로 LED조명이기 때문이다. LED사업을 육성하기 위해서는 기본적으로 LED제품의 부가가치별 기술청사진을 통해 개발할 부문과 당장 활용해야 할 부문을 구분하여, 과감한 투자를 단행해야 한다. 시급히 추진해야 할 과제를 살펴본다.
