Cruise ships are often powered by diesel engines, which consume a significant amount of fuel. The amount of fuel used by a cruise ship depends on a number of factors, including the size of the ship, the speed at which it is traveling, and the weather conditions. A large cruise ship can use up to 250,000 gallons of fuel per day. The fuel consumption of a cruise ship is a major expense for cruise lines, and it is one of the factors that contributes to the cost of a cruise.
There are a number of ways to reduce the fuel consumption of cruise ships. One way is to use more efficient engines. Another way is to reduce the speed of the ship. Cruise lines are also exploring the use of alternative fuels, such as liquefied natural gas (LNG).
