Developing and evaluating the sustainable energy security index and its performance in Malaysia

There is an increasing interest in understanding the crucial factors of sustainable development in terms of security of supply, conservation, and environmental impacts. Based on the current energy perspectives, there are serious challenges in achieving energy security and sustainability. Sustainable energy security (SES) must not only consider the security of energy supply-demand in the long-term and short-term, but also emphasise the balance between energy, economy, social, and environmental factors. Based on the five dimensions of energy security (availability, accessibility, affordability, acceptability, and develop-ability), this study aims to develop and evaluate SES index for Malaysia. The weight of energy security indexes was determined using the entropy weight method.
