Abstract: In this study, the energy planning with four selected renewable energy technologies(RETs); namely, improved cooking stove (ICS), small biogas digester (SBD), large biogas digester (LBD), and rice husk utility (RHU), are considered as alternative options in the residential and industrial sectors to reduce fossil fuel consumption and the corresponding emissions. The Long-range Energy Alternative Planning System (LEAP) model, based on the end-use modeling, is used in the analyses of energy used in the residential sector in the period 2002-2030. In the analyses of ICS, results show that the fuel wood has been reduced around 11,500 ktoe and the emissions have been reduced around 206 million tonnes of COz equivalents during the study period. The emission reduction cost per tonne per year is US$ 1.60 per unit of stove for the fuel wood cooking stove and US$ 0.55 per unit of stove for the charcoal cooking stove. The benefithost ratio in the base year of the fuel wood cooking stove is 2.03 and 10.06 for the charcoal cooking stove For the SBD and the LBD, it was found that the benefits of the SBD are decreasing of LPG consumption and the corresponding emission, decreasing of imported chemical fertilizer, saving exported currency, and increasing income of the farmers. The digester with the size of 100 m3 is recommended to implement first, followed by digesters with the sizes of 50 rn3, 30 m3, 16 m3, and 12 m3, respectiveiy. The benefits from the LBD investment are the reduction of the use of electricity generated by EGAT, the reduction of lignite and LPG, and the corresponding emissions. From the farm's point of view, monetary savings are due to the decreasing of electricity and LPG expenditures. The analyses of RHU show that Thailand has rice husk power plants with total installed capacity of 70.9 MW while the potential is 188.8 MW in 2005 and is projected to increase to 255.6 MW in 2030. Results show that the cumulative lignite saving from electricity generation has been 12.5 million tonnes and 5,756 miiiion litres of imported fuel oil during the study period, respectively. In the analyses of identification and ranking of RETs barriers it was found that the three most important barriers to the adoption of the selected RETs in Thailand are (i) the high cost of investment, (ii) lack of financial sources, and (iii) lack of experts and skilled manpower. Finally, the strategies to introduce and implement the ICS technology are 1) training the stove producers on the ICS production, 2) supporting some money for the stove producers in order to reduce the investment cost of the ICS, and 3) describing the benefit of the use of the ICS and teaching the users to use the ICS. The Sustainable Energy Triangle Strategy (SETS) and the Biogas Pool Project are also proposed for sustainable energy- development in Thailand. In addition, the power generation from the LBD and RHU could be used as options under the Renewable Portfoiio Standard (RPS) framework.
