Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Hi DoDo

I did a little google-driftnetting and found conflicting numbers, but all of them higher than the 2:1 number which I, as well as you, read sometime back from some fairly reputable source (which is why it stuck in my mind).  I see numbers as high as 20:1 (obviously from industry sources) and others in the 12-16:1 ballpark, obviously far superior to the 2:1 ratio.  OTOH wind turbines were rated in one paper at 37:1 (!) which is food for thought indeed.

I had better stop citing that 2:1 number and do some more homework.  will try to rediscover where that number came from.  I wonder if it was the result of factoring in decommissioning costs, i.e. they are not decoupled from this number as I had thought.  

I did come across the interesting tidbit that "The wet storage at Yankee Rowe costs $5 million a year" -- a tidy annual payment on those hot spent rods... well I have a spare-time hobby for the next couple of days I guess, sourcing and attributing EROEI figures for various generations of nuke plant :-)

To be honest, during my Googling, I found one source stating a high ratio (I don't remember anymore, maybe just 1:2), but I discounted it. It was a rough indirect estimate of the total energy input, calculating backwards from GDP numbers and various energy sector statistics.

At any rate, I'm glad you saw that about wind turbines, for I am a big wind power advocate.

(A fond memory of mine is when an American wrote me that there is a wind farm near him that kills many birds, I could impress him by telling him where he lives: near the infamous Altamont Pass.)

(btw way, I googled 'jerome EROEI' and Google came back with the post, but alos asked "wouldn't you want to try "Jerome Heroes"?...)

Heh, Jerôme, now I remember, seeing that post of yours at MoA triggered my Google search!

you needn't even use "jerome", I rediscovered that thread using "nuclear plant eroei"...  :-)

am collecting some links (lunch break!)...

One point in regards to repaying decommisioning costs: If you set the environmental purity barriers high enough then nothing is possible. If there were a few permanent disposal sites and some reasonable rules about getting the waste to the sites, decommisioning would not be as expensive.

France seems to be running her atomic plants profitably...
