Do you understand how corruption works in SouthEast Asia? Do you understand the threat of China simply “stealing” / “destroying” other countries infrastructure? Imagine if China could cripple Singapore by cutting undersea cables etc, what would happen to WindFarms that are on the ocean surface.

Singapore PHYSICALLY CANNOT run WindFarms of the size and scale you are talking about. Not on their own territories and definitively not in other surrounding countries territories. Singapore depends on Water from Malaysia already( even then Singapore is installing Desalination plants in attempts to reduce the dependencies as we speak ) And If Singapore decides to depend so much on their neighbours, there is a real and imminent threat of corruption/sabotage/malfeasance/crimes that can seriously affect Singapore.
