Why is that, in every discussion about renewable sources (hydro, wind, solar), the pro nuclear crowd has to bring the coal, only to try to make nuclear look better? Those pushing for renewable sources also don't like coal, so don't hide the nuclear problems with the coal problems.
The point is that by pushing for renewables at the exclusion of nuclear, the tree huggers have successfully kept coal firmly entrenched. Renewables are expensive, and they don't have the energy density of coal, much less Uranium. Without the political and emotional baggage, nuclear could have completely replaced coal decades ago, not "hopefully some time in the next 20 or 30 years, if we're lucky."
