A Mini Review on Energy System Modelling for Enhancing Energy Efficiency in Malaysia

Abstract Energy efficiency is an important energy consumption parameter to indicate the efficient use of energy. Through enhancing energy efficiency, the harvested energy (fossil or non-fossil) could be used in the most impactful manner, which reduces the energy wastage and carbon emission. This study performs a critical review of energy system modelling, which involves the modelling studies of renewable energy and energy efficiency measures for the national energy sector. The energy value chain is typically related to the national energy policies. Thus, this study continues with a review of the national energy policies from several countries. This study concludes with comprehensive comments and analysis on the feasibility of the national energy system modelling perspective for Malaysia to achieve the 8% of energy efficiency savings by 2025 for sustainable energy development.
