Abstract: Energy is the essence of existence and prime mover of economic development. The reliable and efficient energy services can be underpinned by efficient utilization of the existing resources.
This research presents an overview of the status of consumption of fuels by different subsector of manufacturing industries along with its end uses and their associated emissions. The end-use methodology of the Long Range Energy Alternative Programming (LEAP) framework has been used to calculate the base year energy consumption of different sub-sector as well as project the future energy demands and global warming potential for planning horizon of 38 years, taking the base year 2012.The scenarios namely business as usual (BAU), Low growth (LG) medium growth (MG), higher growth (HG) and BAU equivalent respectively includes different economic growth rate scenarios and the combined policy intervention scenarios. This includes the efficient technology and penetration of renewable energy technology which helps in reducing the global warming potential. The manufacturing value added by manufacturing industry is calculated as 51650.2 Billion Nepalese Rupees and energy consumption is 27.
56 Million GJ at the base year 2012. Compared to Business As Usual (BAU) case, the energy demand is decreased by 38.3% in low economic growth were increased by 17.7% and 32.3% compared to medium and high economic growth rate. Since BAU-Equivalent is time variance, the energy demand is increased by 12.
89% in the year 2030 whereas decreased by 20.04% and 1.84% following 2040 and 2050.The energy demand is decreased by 5.
8%, 2.5%, 0.1%, and 32.4% with respective efficient motive power, efficient boiler, efficient lighting and efficient process heat compared to business as usual.
Development of efficient scenarios like efficient lighting, efficient motive power, efficient process heat, efficient boiler and combined efficient technology result shows that huge amount of energy can be saved with reduction of Green House Gases. Apart from efficient technology, introduction to renewable energy technology and fuel switching to efficient and sustainable fuel will significantly reduce the global warming potential (emission) significantly compared to other scenarios.
