“…For instance, at plant level, the Energy Performance Index (EPI) is an indicator used for benchmarking energy usage per unit area, from which the energy consumption of TBS can be properly considered. Thus, due to the complexity of the industrial processes and different applications of energy efficiency indicators, Schmidt et al [48] propose a classification and a generalized calculation methodology by using templates for measuring the energy efficiency of manufacturing activities, and considering from factory level to process and product levels.…”

Since the depletion of fossil energy sources, rising energy prices, and governmental regulation restrictions, the current manufacturing industry is shifting towards more efficient and sustainable systems. This transformation has promoted the identification of energy saving opportunities and the development of new technologies and strategies oriented to improve the energy efficiency of such systems. This paper outlines and discusses most of the research reported during the last decade regarding energy efficiency in manufacturing systems, the current technologies and strategies to improve that efficiency, identifying and remarking those related to the design of management/control strategies. Based on this fact, this paper aims to provide a review of strategies for reducing energy consumption and optimizing the use of resources within a plant into the context of discrete manufacturing. The review performed concerning the current context of manufacturing systems, control systems implemented, and their transformation towards Industry 4.0 might be useful in both the academic and industrial dimension to identify trends and critical points and suggest further research lines.

“…The amount of energy produced on-site needs to be recorded and examined in order to be balanced with the power acquired from the grid. "Electricity used from On-site Generation (EOSG)" calculates the electricity produced by RES to the electricity produced on-site plus the electricity from the grid network [45]. Energy production measurements, technical specifications of the system and grid, legislative framework issues are required for its definition.…”

During the last years a variety of numerical tools and algorithms have been developed aiming at quantifying and measuring the environmental impact of multiple types of energy systems, as those based on Renewable Energy Sources. Plenty of studies have proposed the use of a Life Cycle Assessment methodology, to determine the environmental impact of renewable installations when coupled with storage solutions, based on a pre-selected repository of Key Performance Indicators. The main scope of this paper is to propose a limited number of best fitting, and at the same time easily adaptable to various configurations, list of KPIs for the case of renewable energy systems. This is done by capitalizing on the environmental and energy performance KPIs tracked in the open literature (e.g. "Global Warming Potential", "Energy Payback Time", "Battery Total Degradation", "Energy Stored on Invested", "Cumulative Energy Demand") and/or other proposing new simple, scalable and adaptable ones, (e.g. "Embodied Energy for Infrastructure of Materials and for the building system", "Life Cycle CO2 Emissions", "Reduction of the Direct CO2 emissions", "Avoided CO2 Emissions", "CO2 equivalent Payback Time"). Moreover, the proposed KPIs are distributed according to the individual phases of the entire life-cycle of a related component of a renewable energy system, each time the environmental impact refers to, i.e. manufacturing, operational and end-of-life. Apart from that, the current paper presents a necessary base grounded approach, which can be followed for a holistic approach in environmental point of view of renewable-based technologies, by addressing the potential competing interests of the relevant stakeholders (e.g. profit for the market operator in contrast to low-cost services for the consumer). All in all, the scalar quantification of the environmental impact of multiple energy systems, through a list of proposed assessment criteria, being evaluated in terms of the selected repository of KPIs, enables the comparison on a fair basis of the available energy systems, irrespective if they are fossil-fuel or RES based ones. As a typical example, a simple standard model of a photovoltaic integrated with an electric battery is selected, for which indicative indicators are provided.

“…The same study showed that around 36% of the energy input to the textile industry is lost on site (e.g. in boilers, motor system, etc) [17][18][19].Energy audit of an industry is a systematic procedure which aims to evaluate that existing energy consumption and also it is a method to evaluate the existing pattern of energy consumption, according to the BEE norms, we can compare the existing measurement with the standard one to find out the energy conservation opportunities in it, this will improve energy efficiency and reduce production cost [4][5][6][7]. Normally, an energy audit is carried out by certified energy auditors / certified energy manager .…”

Electrical Energy has become a one of the vital factor in deciding the total production cost and maintenance cost . Day by day, energy demand keeps rising in the industrial sectors because of this reason it is essential to reduce energy consumption for that energy conservation is must needed action. Energy Audit is the prime tool for finding the energy conservation oppourtunities. It helps us to make attempts to balance the total energy inputs with its use and serves to identify all the energy flow in a facility. Energy auditing will not only save money but it also improves the quality of electrical energy supply. Energy Conservation and Energy efficiency in industry has to be improved, this is the prime motive for Government of India. This paper shares the experiences of the authors on Electrical Energy Conservation Projects carried out in a Textile Industry situated in Tamilnadu State. We have used Load Manager for the observation of electrical datas during normal working load condition itself. These datas helps us to gain the electrical energy audting experience in the industry
