Singapore's pathways to a net-zero power sector in 2050
by Shuyue Yan
Ms. Shuyue Yan is a PhD student in the Department of Civil and Environmental Engineering under the College of Design and Engineering (CDE).
Synopsis:
Behind the world's ambitious net-zero pledges, a significant gap exists in providing actionable plans and addressing the uncertainties in such transitions. In this study, we present Singapore, an urbanised city-nation with limited natural resources, as a case study to explore viable pathways towards a net-zero power sector by 2050. We employ an energy expansion model known as the Pathways for Renewable Energy Planning coupling Short-term Hydropower Operation (PREP-SHOT) to analyse 3,600 different scenarios based on three distinct outlooks, namely "Diversified Mix", "Dominated by Hydrogen", and "Reliant on Import".
Our study highlights the impact of policy, technology, and resource constraints on carbon emissions and economic costs throughout the transition. The findings could also provide insights for nations with similar challenges.

Human Health and Potential in a Warming World
by Assoc. Prof. Jason Lee (Director, Heat Resilience and Performance Centre, and Co-PI, Climate Resilience Project)
Synopsis:
Feeling hot especially in the tropics is often perceived as normal, but most are unaware of how heat can be detrimental to our overall health, well-being and performance. While heat stress is the effect of the environment on the individual, heat strain is the resultant thermal load the body experiences predominantly from the weather, workload and clothing. The three pillars of human health and performance are diet, exercise and sleep, and each of these can be hindered by heat stress. Heat stress not only increases the risk of heat injury but can also degrade with work productivity. In addition, heat stress can compromise decision making, thereby increasing the risk of accidents. The ageing population, which includes those suffering from chronic diseases, can also be compromised by heat stress. A multidisciplinary approach is therefore required to tackle this multifaceted whole of society public health problem.
