Renewable energy is one of the key drivers for reducing CO2 emissions in the future. In order to support effective policy-making relating to renewable energy; estimation of available potentials mixed with all energy resources including fossil fuels is needed. However; previous research has sometimes focused on only one particular approach. Therefore; a diversified analysis of potential renewable energy contributions to energy supply in Asian regions was carried out in this paper. In order to estimate physical potential; a grid cell approach using geographical information system (GIS) data was adopted. Once the physical and technical potential had been estimated; the economic potential was then calculated. Socio-economic potential was analyzed using energy outlook data collected and reviewed from various publications in order to assess trends in energy demand and supply. The results indicate that almost all Asian countries will continue to develop and that the demand for energy will grow. With the aspect from potential amount; renewable energy supply is effective even though fossil fuels will continue to dominate totally energy mixes for the foreseeable future. In renewable energy supply; potential of solar is dominated and bears on wide implication compared with that of wind and biomass. To ensure the best possible results; further research should be carried out on the optimal schedule for the multiphased introduction of renewable energy in long-term policy.
