I was trying to estimate the mining footprints of solar and nuclear, and came up
with some very tentative rough estimates that ore input for solar energy might have an energy density (per unit mass) ~ 5 to 80 times coal, while nuclear (convential US fuel cycle) may be ~ 20 times coal — on the solar side, this doesn't include some balance of system components, and on the nuclear side, it only includes the U, but on the solar side, the actual energy density could get much higher
with recycling of the same material into multiple successive
generations of solar energy devices, and on the nuclear side, breeder
reactors.
To my mind, the Fukushima failure also builds the case for the kind of push under way in China, which is moving forward

When San Onofre closed its last
reactor in 2012,
with no formal replacement plan in place, there was a short - term spike in natural gas consumption (worsened by the simultaneous arrival of a multi-year drought, which cut hydroelectricity
generation) and an increase in California's greenhouse gas emissions.
Nuclear defenders are calling for keeping things in perspective — fossil fuels, they point out, have many more costs and risks associated
with them than nuclear power; and newer
