The scoop: by tonnage, 40% of what is transported by sea is oil, coal, and LNG.
By switching to local sources of energy (renewables mostly), humanity can seriously lower the impact of ships on the oceans, and stop burning as much fuel to move them, too.
I'd like to add that all these fuels are very energy-dense. Producing as much energy locally would not be an easy or inexpensive enterprise.
