In the contemporary industrial landscape, energy efficiency has evolved from being a discretionary objective to an imperative for both competitiveness and sustainability in manufacturing. Excessive energy consumption is increasingly becoming the "eighth waste" in lean manufacturing. As such, policymakers and industrial leaders are prioritizing strategies to optimize energy use across sectors. The integration of lean manufacturing principles with energy management practices has emerged as a critical strategy for achieving sustainable industrial efficiency. This study introduces a unique methodology that quantifies the energy consumption associated with each component within a given manufacturing process. Beyond direct energy consumption, the research also explores opportunities for measuring and reducing indirect energy use. These strategies contribute to a comprehensive, energy-efficient manufacturing ecosystem. By combining Value Stream Mapping (VSM) with specific energy consumption (SEC) metrics, the proposed approach facilitates systematic identification, measurement, and rectification of energy inefficiencies. This framework provides a structured pathway toward enhancing energy efficiency, thus advancing sustainable manufacturing practices. Ultimately, this paper presents a scalable and adaptable framework that manufacturing firms can implement to align operational productivity with sustainability objectives, thereby promoting a more energy-conscious and resource-efficient industrial environment.
