Simple answer. Any transference of energy is going to have losses. How would you create steam? By burning fossil fuels of course. So now you burn the fuel, create stream, use steam to generate electricity, use electricity to power ship. That’s two extra steps and potential loss of energy as opposed to just directly powering the ship by burning fuel. More energy lost means less efficient. Less efficient means more fuel burnt. Burning more fuel costs more money.

Your last sentence is spot on.

Fossil fuels are way cheaper. And what does the planets and humanitys survival matter opposed to some cruise liners revenue.

Aircraft carriers are powered by nuclear reactors so it's very much possiblebtw
