I was wondering how much of worldwide shipping is oil. Just moving crude and products around the world. I was expecting a significant number, but was surprised to learn it is almost one third of all shipping by weight. Not only does it take energy to move all of this oil around, but this also produces pollution. I wonder how this all compounds when you consider nearly all renewable energy is locally produced and requires no transport, at least not in the traditional sense. From Statistia.
In terms of tonnage, oil tankers accounted for around 29 percent of global seaborne trade that year.
