摘要：The greatest source of GHG emission from energy sector comes from fossil fuel combustion. According to PLN, 63.75% of electricity distribution in South Sumatra is derived from coal combustion. Coal is a non-renewable energy source and will deplete in a few decades. The research objective is solving problems related to energy efficiency and GHG emission reduction by reducing electricity consumption in street lighting sector. The research method was carried out through SPSS statistical analysis and LEAP analysis which had been justified based on observation on the survey results of 1,619 street lighting unit at four distribution areas of Palembang. The implementation of electrical energy efficiency is carried out by replacing Son T 250 W lamps into LED lamps with different power. The SPSS statistical analysis determines that 1,000-unit street lightstreet lighting require light intensity quality of 1,570 lux with correlation coefficient of 0.214. GHG mitigation was conducted in accordance with convenience and safety standards for road users in which energy efficiency from the replacement of 3,741-unit energy-saving lamps can reduce GHG emissions by 1,650.9138 tons of CO2e with benefit economic 2,911,481,740 rupiahs. In addition, based on LEAP analysis, if 8000 units of LED lamps replace Son T lamps, the electricity consumption of Street Lighting in 2030 will decrease with a projected efficiency of 17.48%.
