Instead,I calculated we need 3500 GWe of nuclear power (x 10 times

(it's reasonable,but I'm not very sure of this share).Of course I
supposed
all current 200 milions of vehicle are electric or plug-in hybrids,all
current electricity is nuclear and heating needs are 2/3 by high

electric pump (COP >4) and 1/3 by district heating from same nuclear
plants

See what I mean? it's a big number, but it just isn't THAT big.
it's attainable.

Yes I agree to you but the number we need is 3500 not 10'000 1 GWe
reactors.It's worthwhile to note that only Chineses have a 1500 GWe
nuclear
program for the middle of this century (and maybe India has a similar
plane). Anyway thanx for the links

On the global warming side, every new nuclear plant used to take
coal plants offline reduces world co2 emissions by 8,760,000 Mtons/
year. World total co2 emisions today are somewhere in the
neighborhood of 7,000,000,000 mtons/year, so every reactor equals a .
1% reduction in WORLD co2. Show me where it's possible to get a
bigger bang for the buck anywhere than that!

well, I was anticipating a doubling of primary energy demand in
the 20 year construction time frame. With asia coming online, that's
probably low. so we're probably looking at more like 5000 total

That's true,too


Basically, we're both doing the lazy engineer thing and speccing
for the absolute worst case plus a safety factor. Your analysis was
slightly more detailed than mine, so naturally, in the way of all
engineering, more detail means a smaller requirement. More
examination of the energy requirement of PHEVS would undoubtedly
decrease your 3500 number, as would a proper consideration of the 20%
of electrical generation that's renewable *today* (hydro, wind, GT,
etc.) as would consideration of the fact that it's nonsensical to
cease using ALL fossil fuels, and many other factors. I think
700-1000 new reactors worldwide would go an IMMENSE distance toward
alleviating the problems.
