Energy security has emerged to be one of the top priorities in a nation’s policy. Energy is an essential foundation for economic development of nations, as countries with high economic development are seeing an increase in energy in demand. Thailand meets the criteria stated and the nation’s energy policy goal is “to satisfy the energy needs of the country while achieving sustainable energy security” (National Science and Technology Development Agency, 2011). Policies focus on energy from domestic sources in order to balance the high importation of fossil fuels. In the roadmap to energy security, Thailand plans to expand the utilization of domestic renewable energy.
