There are two main forms of energy that are consumed by industries, namely, oil and electricity. Globally, industrial electrical energy usage accounts for 40% of total usage and is a major contributor to CO2 emissions. There are several different uses of electrical energy in a factory, such as lighting, cooling, heating and supplying power to machineries. The electrical energy saving potential of industry systems largely remains unrealized because it is deeply embedded in industrial management and operational practices. Lighting is an essential part of any industrial load, and hence, it plays a vital role in reducing inflated energy bills. This paper describes two practical measures that have been implemented in a railway workshop and the energy saving achieved in lighting. Energy savings in lighting not only reduces the energy bill but also reduces CO2 emissions.
