I mean, the literal meaning of efficiency would be the capacity factor (how much energy is actually extracted out of the inputs over how much energy the input contains) which is very measurable. I'll concede that that is unfair, but even then there's the extremely accepted measurement of land use per unit of energy:
(Solar is represented as CSP, concentrated, and PV, photovoltaic)
Edit: energy over land use→land use per unit of energy
Yes, so nuclear uses 100 times less land for the same energy. The unit is hectares per TWh.
The United States could meet its entire electricity demand just by putting solar panels on the land we currently waste growing corn ethanol.
The land argument is beyond grasping at straws. The last refuge of the incompetent.
this is true. I'm not saying that we should stop efforts to install solar to install nuclear instead. as you say replacing the 12 million ha of corn ethanol with solar would produce nearly three times the US demand of 4200 TWh/y (with the averages from the chart above, you have 12 million/1000=12000) i'm for solar. however, i'm also saying that the us could meet nearly 300 times its entire electricity demand just by putting nuclear reactors on the land we currently waste growing corn ethanol. we don't have to debase nuclear for solar
Do you just burn piles of money for fun? Is that your hobby?
Who gives a crap what the maximal power output per land area is? It's utterly irrelevant.
for one thing, it's exactly what your argument about corn ethanol is
what is your standard of evidence? you've moved the goalposts three times now. first it was "define efficiency", then "by the definition solar is better", and now this which i still don't understand
I have been searching and providing you with sources. Give me a source that compares any of these other definitions of energy I haven't yet covered between nuclear and solar. Per land is the only one widely accepted and what an expert will assume the title says.
what does this even mean
