The total final energy consumption in Thailand rised up from 47,806 ktoe to 60,260 ktoe during 2000 to 2004, with an
annual average growth rate of 5.96 %, while the annual growth rate of gross domestic product (GDP) equaled to 5.16% in the same period. During 1985-2001, the elasticity of energy demand was found to be 1.4:1. In 2005, Ministry of Energy set a target to promote renewable energy and energy efficiency in the Renewable Portfolio Standard (RPS) and increase usage of renewable energy from 0.5% to 8% within year 2011, and reduce energy elasticity to 1:1. To achieve the target, Thai government has to overcome barriers in 2 major areas, which are renewable energy and energy efficiency. Thus, the development in energy policy measures is required in order to promote the renewable energy utilization and increase energy efficiency in the consumption sectors. Since non-electricity is the main form of energy that consumed in the residential sector, therefore, the efficiency improvement of cooking stove results in the largest amount of energy savings. The total energy saving in the residential sector is 7,291.6 ktoe, accounting for 29.42% of total residential final energy consumption in 2020. This scenario also helps in the reduction in the largest amount of carbon dioxide emission.
