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,
