I view renewables as energy farming, and city-states like Singapoure, lixemburg, etc. Are not very suitable for either form of farming :) for most countries the calculus is very different. UK has been developing sea based wind turbines quite succesfully, thats something that could work for singapore.

I view nuclear as a bit of a lost cause to be honest, they take long time to build, cost a lot upfront, you need a lot of expertise around them, and they would require a miracle of PR. It does not appear likely that countries that do not have an established nuclear industry will suddenly become nuclear powered. Thats just the way things appear to be heading, and its a shame.

Besides, don't underestimate the infrastructure needed to refine fuel, manufacture fuel rods, deal with waste, etc. If you outsource all of that, you are not terribly energy independent.

I think the only hope for nuclear industry is small modular reactors, and that's only if a massive amount investment comes through.

What I meant is ofcourse de-carbonise economy, Singapore can't be energy independent in meaningful sense as it does not have fuel sources of any kind. And solar/wind do not count as there could totally be still nights.

I frankly dont understand how an energy source that can shift from 100% to 5% capacity on its own whim, independent of its user's needs could get so much attention and considered viable replacement for something predictable..

There was not a single economy decarbonized on solar\wind, even for those that tried really, really hard (see Germany). And we have example where it worked, in short 10 years.

There are countries still that can build nuclear on time and on budget - see South korea for example. Wonder why they don't get all the orders for urgent decarbonisation needs.
