There’s more than enough energy in the wind, and modern sailing technology has come a long ways. Some modern recreational sailboats can cross an ocean as fast as a cargo ship on just wind power, and speed isn’t even much of a factor for a lot of shipping. With the right tech I think fuel free shipping can disrupt fossil fuel shipping just by being cheaper.
Back when engines first replaced sailing fuel was nearly free, and sailboats were incredibly slow, dangerous, unreliable, and didn’t sail upwind well, and all that has changed- time to take another look.
