Mining and shipping is required for all forms of energy.
Of course it's gonna be per twh because that is the only way to measure that makes any sense.
Kurzgesagt has a great video explaining everything here:

- JoeAltmaier 6y agoMining and shipping are very, very different by source - every watt of coal is shipped. Only the machinery for solar is shipped. Nuclear fuel is shipped in pounds not megatons, but they are fantastically dangerous pounds. Etc. Utterly different in effect on risk. The linked chart seemed to list totals. Did it have per TWHr? I missed that.
- Mrdarknezz 6y agoIf you want to talkt about emissions instead here is a great summary from the Swedish Life cycle analysis by energy source: Nuclear: 6g CO2/kwh Hydro: 9g CO2/kwh Wind: 13g CO2/kwh Solar: 24g CO2/kwh This includes everything from construction to mining. The data comes from Swedens state run energy company Vattenfall LCA report https://www.vattenfall.se/foretag/miljo/epd/ https://www.vattenfall.se/foretag/miljo/epd/ and here is a an article that summarizes it https://blog.karnfull.se/blog/kaernkraftslogik-1-klimatsmart https://blog.karnfull.se/blog/kaernkraftslogik-1-klimatsmart
