See page 92 of David MacKay's wonderful "Sustainable Energy Without the Hot Air" [1]. Figure 15.8 compares the energy intensity of different transport methods in kilo Watt hours per net ton kilometer. Shipping and rail are basically 1/10 to 1/20 of roadfreight. His conclusion is "Transporting freight by ship is surprisingly energy efficient". [1] https://www.withouthotair.com/c15/page_92.shtml Anyone with rational concerns about transportation costs for materiel should be advocating to dismantle and depopulate Denver. Moving mass a short distance up by truck costs more than moving it half way around the planet by ship. Inland navigation is similarly negligible, which is why the whole Minnesota-Ohio-Pennsylvania steel complex works so well. reply Ok, done!
