"1 barrel in 7 out" I bet if you look that ios tearms of kwh in and kwh out you get better with a nuclure plant and cedrtainley will with some of the future tech nucler.
I would be prepered to bet if we bit the bullet and went for a full on nucler stratergy we could easley out produce our current socirys energy needs but we would then have the problem of converting it inot the form we want
in short as peek oil aporces pepol will convert things to other forms of energy use (we are allready seeing that with the rise albit it slow of the electric car). or things like man made oil (using nucleur power as a feed) will become econopmicley viable the laws of supply and demand in operation
