Abstract. A targeted energy analysis was carried out in a textile industry focusing on lighting system. It is observed from the study that the industry can replace the existing TL-D 36 W/54 fluorescent tube lights with energy efficient TL-5 28 W/865 fluorescent tube lights with electronic ballast. This has resulted in energy saving of 206388 kWh per annum. The corresponding CO 2 mitigation is estimated at 167.174 t CO 2 /annum. An experiment was conducted to identify the exact light intensity of the proposed lighting system. The result shows that the light intensity has reduced by 11.1 % which is insignificant compared to energy saving and CO 2 mitigation. The investment for the new lighting fixtures is estimated at INR 0.468 million with cost saving of INR 1.65 million which has return on investment of just 3.3 months. Introduction Energy is one of the major inputs for the economic development of any country. Industrial sector is the largest user of energy in India and many parts of the world [1]. Lighting systems are often the second greatest user of electric power next to heating and cooling systems [2]. The results of the energy audit in the Malaysian rubber and rubber producing industries showed that lighting is one of the major fractions of total energy consumption [3]. Lighting is an area, which provides a major scope to achieve energy efficiency [4].The level of reduction in Specific energy consumption depends on the amount of investment and the use of modern technology [5]. The energy auditing is a key strategy to successful running of an industry with energy saving [6]. A saving of 15 to 20 watts per tube light can be achieved with electronic ballast. [7]. Previous studies have reported that implementing a few select options at little or no cost in the industrial sector could reduce energy related green house gas emissions by 10-30% [8]. Reducing energy consumption through a detailed energy audit is a cost effective methodology in any energy optimization program [9]. Energy audit is the starting point of an energy management plan to reduce the overall cost of production [10]. As a result of the impressive growth attained by the Indian Power Sector, the installed capacity is predominantly coal based and therefore, is a major source of carbon dioxide emissions in India. Hence, there exists significant scope for reducing the CO 2 emissions in the country [11]. In this view, an energy analysis was carried out in a textile industry focusing on lighting. The lux level of the existing luminaries and proposed luminaries was compared. An estimation of energy saving potential and energy related CO 2 emission is also made with economic analysis. The findings of the analysis are presented in this article.
