Freight can also mean shipping, I’m not sure electric ships are a thing yet.

yes. And if you look at costs:

- $0.005 to $0.01 per ton-mile (for ocean ships)

- $0.05 to $0.08 per ton-mile (for diesel trucks)

- $0.015 – $0.025 per ton-mile (for electric trucks)

- $0.007 per ton-mile (for diesel trains)

- $0.002 per ton-mile (for electric trains)

- $0.002 – $0.004 per ton-mile (electric ships, not widely deployed yet due to battery weight)
