holy guacamole said..Depends on how you measure reliability and performance. We're not talking about going 100% solar, wind and hydro tomorrow. These technologies are very reliable. If you mean reliable as in 100% power 100% of the time then no, that kind to dumb argument is not the issue.
Efficiency? Pfft. We have so much sun we could power the entire planet. Who gives a toss about 20% efficiency in a solar PV cell? How about hydro and wind? They are very efficient. Convenient to forget those...
How efficient is nuclear power anyway? How much of the energy in the atom actually goes into boiling water? Probably much less than 20%.
When are you going to address the toxic chemicals pouring out of current reactor core melt downs in Japan?
What is the true death toll from those exposed to the radiation from Chernobyl's reactor melt down?

Use it as seasoning on your steak...
Id' say someone is wearing deep rose coloured glasses....

Reliability and performance. Yes it really is about getting 100% of the power output 100% of the time. On demand. Scalable.
So you're happy to over-build your installation by 300% or more? You have 120 hydroelectric power stations, producing 8.8Gw. 120 versus what could be 8 nuclear. Someone do the math on costs there.
You design a 1Gw nuclear power station, you get up to 1Gw, scalable to demand . That's what we're talking about. Your 11Gw "renewable" station in the link there won't be producing 11Gw even when the sun is shining and the wind is blowing. And you still have to "store" it. Are you factoring that into your pricing?
About the time you address the toxic chemicals involved in producing and using PV

You can look up what's "pouring out" of ****ushima and please, pay attention to what the actual levels mean. The damage is in the dose.

Simply flying commercial will nail you with four times background radiation. OH MY GOD!!!
Exceeding annual doses won't kill you; in fact, case studies of the Chernobyl "Liquidators" have found no increases in cancers or tumors in the surviving cleanup workers, and some sources attribute as few as 50 deaths to the actual incident. The "liquidators" biggest complaints seem to be ever decreasing benefits...
en.wikipedia.org/wiki/Chernobyl_liquidatorsNobody died from radiation sickness at ****ushima. ALL the casualties were due to the earthquake and tsunami.
Radiation Is radiation and toxicity is not radiation. Uranium is about as chemically toxic as lead. You can handle yellow cake with as little protection as surgical gloves and mask. Just ... don't eat the yellow cake. The toxicity will kill you -- not the radiation.
You really need to learn the basics about the science involved. From actual scientists, not The Guardian op eds or Greenpeace freak-out brochures.
