A renewed discussion surrounding nuclear energy is emerging in Singapore and throughout ASEAN, driven by a complex interplay of factors. Geopolitical instability is prompting nations to seek energy independence and diversify their sources, lessening reliance on potentially volatile suppliers. Simultaneously, the urgent need for decarbonization to combat climate change is pushing countries to explore all available low-carbon energy options, including nuclear. Technological advancements, specifically in small modular reactors (SMRs), are making nuclear power more feasible for smaller grids and offering enhanced safety features compared to traditional large-scale plants. These SMRs present a potentially attractive solution for nations like Singapore with limited land area. The reassessment reflects a broader global trend, as countries grapple with balancing energy security, climate goals, and economic development. This shift could lead to significant changes in the energy landscape of Singapore and the wider ASEAN region.
