Also you're basically comparing sales when margin should be the metric. 8.968GWh of "sales" , but how much of that is spent mining it? And cleaning up after it

Also you're basically comparing sales when margin should be the metric. 8.968GWh of "sales" , but how much of that is spent mining it? And cleaning up after it w/ the pollution from burning, the damage to the environment etc etc? Same story for Solar too, i know there is impact, but I would venture that the "costs" are much less, so to speak.

You're not making sense. The proper metric is net delivered energy. Generation is a reasonable proxy for that, though EROEI would give you a better measure. The EROEI of coal is typically very high -- 1:100 to 1:200 or better, vs. 1:6 to 1:20 for solar PV (estimates vary, and are dependent on specifics). Regardless, if you're looking at delivered energy and divide by labor, you end up with the values I've shown. I haven't seen the case presented this way previously and feel it helps illuminate the situation.
