Those glowing accounts of nuclear are industry reports. Objective reports show the opposite. Saying extremely low is, well, extremely POV. You can say "low", but in fact, when you add in the CO2 emissions involved in mining Uranium and making concrete, you are about as bad as burning coal - which is pure carbon. The only reason that nuclear even needs to be mentioned is that M. King Hubbert suggested replacing oil with nuclear when oil ran out, but here we are in 2009 and all nuclear has caused is problems. It currently provides less than 2% of all energy, and at that rate of consumption will run out in 70 years. Let's do the math, up it to 20% and you run out in 7 years - unless you make U-238 into plutonium, and no one wants that - it's bad enough to have enriched Uranium around. So lose the glowing accounts and be objective.
