There has been a significant increase in electricity consumption per cï»¿apita amongst ASEAN Countries in the last two decades. This consumption will most likely continue to increase in the future, indicating the importance of a reliable provision for electricity supplies in the region. ASEAN Countries, however, are concerned that continuing to utilise fossil fuels to generate electricity will increase their carbon emission contributions. Therefore, ASEAN Countries are considering to invest in renewable energy for the generation of electricity. However, few studies have been conducted on the socio-economic and environmental impacts of renewable electricity development in this region. Using an inter-country social accounting matrix analysis for the East Asia Region, this paper compares the socio-economic and environmental impacts of increasing electricity generated from fossil fuels with electricity generated from renewable resources, namely wind, hydro and solar. The results indicate developing renewable electricity can lead to a higher GDP, higher positive spillover to non-energy sectors and lower carbon emissions than developing electricity based on fossil fuels. However, the incidence of poverty in several ASEAN Countries developing renewable electricity can be relatively higher than if they continue utilising fossil fuel electricity.
