The overall cost of nuclear (fission) including uranium extraction, concrete useage (and the CO2 it emits) and waste product storage, is something i have seen. Thorfi mentions the time it takes to bring new plants online... I don't recall the figures - other than being much safer than coal (due to death from ling related illnesses which coal plants and coal mining contribute to)
To do a proper analysis, you can include solar death due to installers falling off roofs... And nuclear seems pretty damn safe, even compared to solar; but battery technology may be the winner here, on all things. For transport, if we replace a system of gas stations with electricity supply points and huge amounts of battery storage, we're likely to get to a point where countries like ireland are powered entirely by wind (while more southerly climates shift to predominantly solar) Solar needs a lot of work, though Spain's Solar Power Towers look amazing ( and have the momentum of a turbine )
I can see a lot of new renewable technologies coming online, but witout storage they will not be fit for purpose for our current economy. Like really massive amounts of storage. Having a transport network which symergizes with the power supply network could amount to massive savings and efficiencies (even with current generation nuclear/gas - you have to leave the plants on at 70% at night - having cars charging their batteries all night to store all this excess production would make a pretty massive efficiency gain - so i suspect we will see battery tech making some advances, basically everyone benefits; especially whoever makes the big breakthrough!)
Some people did listen to Malthus, an ~1 million Irish died in a famine, while the island was a net exporter of food; an the government said, based on Malthus, sure they'll be better off in the long run...
