Sustainable development of the country is possible by adapting various energy conservation measures. Energy conservation helps in using energy in effectivemanner. Application of advanced technology and improved operation and maintenance practices contributes towards energy conservation. Smart streetlight framework is an essential piece of the smart city, which represents 10-40% aggregate power utilization in the city. In this paper the energy audit report is presented for streetlights in the industry and also presented various energy conservation measures with the help of sensors and automation. It was observed that Passive Infra-red (PIR) sensor helps a lot in saving energy where movement of people is low.
