Renewable energy source selection for a green port with AHP

Abstract

In view of the need to reduce the greenhouse gas emission causing global climate change coupled with the necessity to protect the environment around port vicinities, the green port concept receives considerable attention. This concept's motivation is to balance environmental challenges with economic demands such that seaports improve their financial, commercial, and operational performances. In this regard, the use of renewable energy is one of the viable solutions. Based on the analytical hierarchy process (AHP) method, this paper presents a systematic approach for selecting the most suitable alternative of renewable energy sources. The results show that for the case of Kuala Tanjung Port, solar energy is the most favored alternative, followed by wind energy, biomass, and wave energy. It is hoped that this paper provides a starting point to plan for a long-term renewable energy strategy in the context of a green port.
