What consumes more gas planes or ships?

Question

I prefer travelling with ships, but I'm still wondering which is more greener for the environment.

Answer 1

planes are greener

Answer 2

Ships are far more "green" than planes.

Yes, the fuel consumed by a ship is more than a plane, but you have to figure in weight per gallon used.

How much fuel would be used by a plane to carry the same amount of cargo that a large ship transports?

A motorcycle is way more green than a big truck, but what would be more green if you had to move a lot of stuff?  Would you make 100 trips on a motorcycle or one trip in a U-Haul truck?

Answer 3

Ships are not very green.
