Abstract for: Impact of Singapore Green Plan 2030 Initiatives on Electricity Consumption and Generation – a System Dynamics Approach

As an important movement in advancing towards sustainable development in Singapore, the Singapore Green Plan 2030 outlines initiatives and targets for reducing household electricity consumption, adopting cleaner-energy vehicles, growing Singapore’s solar capacity and improving the efficiency of natural gas electricity generation. In this paper, the energy system in Singapore – involving household and transport-related electricity consumption subsystems, solar PV and natural gas electricity generation subsystems and CO2 emissions subsystem – are modelled using a system dynamics approach, so that the impact and projected outcomes of the Green Plan’s initiatives can be assessed. Then, household efficiency improvement and the target for solar capacity are chosen as parameters for sensitivity analysis, with the results suggesting efficiency improvements and solar PV electricity generation can lead to significantly greater CO2 emissions savings.
