I'm sure there's political manoeuvring involved, but are you asserting that this will not be economically advantageous to both parties involved in the trade?
> Any engineer would take one look at this and go yep, let's put a nuclear reactor on one or more of Singapore's 64 surrounding islands.
Some engineers might, but it sounds like a very expensive and high risk proposition.
Hmm, trying to think of some recent accidents that involved nuclear fission power plants built close to sea level.
> Singapore could get oodles of solar from Malaysia but they obviously aren't interested in doing that.
Apart from the political complexities, you may find the air pollution and frequency of storms in that region would significantly impact on the oodle volume.
Parts of far north Australia certainly have a wet season, but I suspect if you compared hours of sunlight per year, it'd be well ahead of Malaysia. Latitude seasonal advantages might also be a consideration.
