Composite index for energy efficiency evaluation of industrial sector: sub-sectoral comparison

Abstract The study investigates energy efficiency performance across 18 main industrial sub-sectors of Latvia in 2017. A composite index methodology was applied to develop energy efficiency index (EEI) that consists of 12 different explanatory indicators grouped in three main dimensions of energy efficiency – economic, technical, and environmental. The obtained results highlighted various opportunities for energy efficiency improvement in all the sectors of Latvian manufacturing industry. The results indicate that there is large potential for energy efficiency improvements in energy intensive sectors such as wood and non-metallic mineral manufacturing. The fundamental issues for each sector could be recognized and addressed to the policy makers.
