I agree with btlim999 that we should not rule out the nuclear option, certainly not without careful study. Anyone wonder why only rich developed countries have nuclear power stations, if they are so unsafe?
What exactly is the established international norm for a nuclear power station? It is generally accepted that greenhouse emissions contribute to rising sea levels, and we rank quite high in terms of emissions per capita.

Faced with the certainty of rising sea levels and the uncertainty of rising sea levels, which will flood substantial portions of Singapore, we need to convince the world to reduce emisions. Granted, we are a small country, so we acting alone will have no meaningful impact. But consider what will be our moral position when we go ask major carbon emitters to cut back on emissions? "Yeah, but you are a major emitter yourselves. On a per-head basis, you emit more carbon than we do."
And given the way our economy is structured, does anyone think we can cut realistically power consumption by 20%? If not, we have to find ways of generating that power with less carbon footprint. And at present, nuclear appears to be the only realistic option.
