Analyses of Energy use and CO2 Emission in Residential Sector: Case Studies in Thailand and Vietnam

This paper presents the energy consumption and CO2 emissions in the residential sector for both Thailand and Vietnam. The Long-range Energy Alternatives Planning (LEAP) model is employed for analysis of energy consumption and CO2 emissions under three scenarios. The business-as-usual (BAU) scenario, which represents the residential sector without any climate policy intervention. The energy system in the base year 2010 is modeled using the secondary data and then existing energy consumption trends will be projected to the end of the planning period, that is 2030. The demand side management (DSM) scenario focussed on the efficiency improvement of four electric appliances: lighting, air-conditioners, cooking, and refrigerators to reduce the energy intensity in the residential sector. In the renewable energy (RE) scenario, the renewable energy utilization is used to analyze the energy consumption and CO2 emissions in the residential sector in both countries. Results are compared for both countries to find out which scenario is suitable for energy savings and CO2 emission reduction.
