Table 1 shows the energy efficiency of different modes of transport by kilojoules of energy used to carry one ton of cargo a kilometer (KJ\/tkm). As you can see, water and rail are literally tons and tons\u2014orders of magnitude\u2014more energy efficient than trucks and air transportation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Table 1 Energy efficiency of transportation in kilojoules\/ton\/kilometer (Smil 2013), Ashby 2015)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(A) \u2026\u2026\u2026\u2026\u2026Transportation mode<br>50\u2026\u2026\u2026\u2026\u2026.

So an 8,000 TEU container ship consumes 225 tons of bunker fuel per day at 24 knots, but at 21 knots\u00a0 consumption drops to 150 tons per day, a 33% decline. While shipping lines would prefer consuming the least amount of fuel by adopting lower speeds, this advantage must be mitigated with longer shipping times as well as assigning more ships on a pendulum service to maintain the same port call frequency. The main ship speed classes are (Notteboom 2009):<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2026click on the above link to read the rest of the article\u2026<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Oil consumption of containerships Preface.&nbsp; Since 90% of international goods move by ships, I was curious about how much fuel they burned.&nbsp; It\u2019s a lot: The very large container ship CMA CGM Benjamin Franklin above, which can carry 18,000 20-foot containers, carries approximately 4.5 million gallons of fuel oil, which takes up 16,000 cubic meters [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[3],"tags":[11859,588,1039],"class_list":["post-53536","post","type-post","status-publish","format-standard","hentry","category-energy-2","tag-energy-skeptic","tag-oil","tag-oil-consumption"],"_links":{"self":[{"href":"https:\/\/olduvai.ca\/index.php?rest_route=\/wp\/v2\/posts\/53536","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/olduvai.ca\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/olduvai.ca\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/olduvai.ca\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/olduvai.ca\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=53536"}],"version-history":[{"count":1,"href":"https:\/\/olduvai.ca\/index.php?rest_route=\/wp\/v2\/posts\/53536\/revisions"}],"predecessor-version":[{"id":53537,"href":"https:\/\/olduvai.ca\/index.php?rest_route=\/wp\/v2\/posts\/53536\/revisions\/53537"}],"wp:attachment":[{"href":"https:\/\/olduvai.ca\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=53536"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/olduvai.ca\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=53536"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/olduvai.ca\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=53536"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
