A nuclear plant costs about $2000 per kilowatt of generating capacity.
Meaning a one gigawatt plant would cost $2 billion.
Adding in other random factors and that goes up to, say, $4 billion.
World energy consumption is 15TW.
Or, 15,000 gigwatts.
The cost of this energy, if we built nuclear plants to suddenly replace all of our current use, would be $60,000 billion or roughly equal to global GDP.
Now obviously some of the world is already powered by nuclear power but I'll ignore that fraction for now.
We do not need to build all 15,000 nuclear plants in one year. We have decades to do it.
Spread out the costs over a third of a century and suddenly the figure drops to 3% of GDP.
Now that is a far more manageable number, no?
As for Coal-to-Liquid...I prefer keeping the planet as clean as possible. CTL is a distraction and an ecological disaster (much like corn ethanol). God willing this won't be tried on a large scale and based on the poor profitability of these projects, it probably won't be tried.
But I'm still worried about the possibility that China might decide to subsidize its liquid transport fuel market by converting its dirty coal reserves...
If that happens, I expect China's population to contract rather sharply do to air pollution, water pollution, food shortages, etc.
