Green cruises use eco-friendly vessels to reduce energy consumption and waste production. Cruise lines are refurbishing or building new, greener ships with features such as tinted windows, energy-efficient appliances, and alternative energy sources like solar panels and biodiesel. Some ships accept cargo to maximize utility and profit. New green cruise ships use lighter materials to reduce fuel consumption. Critics argue that even green cruise ships are still harmful to the environment.
A green cruise is a type of cruise that takes place on board a vessel equipped to reduce its impact on the environment, both in terms of the amount of energy it uses and the amount of waste it produces. In recent years, the cruise industry has come under fire for massive oil spills, dumping of sewage, and general non-environmental practices. Some critics say that even the greenest cruise ships are still pretty bad for the environment, but many of the cruise lines that are refurbishing their ships or even building new, greener ships seem to be proud of their progress.
There are a number of features that can be found on a green cruise ship that reduce the amount of energy the vessel consumes. Some green cruise ships have tinted windows that keep rooms inside the ship cooler and reduce the need to use air conditioning. Others may be fitted with more energy efficient appliances. There are even green cruise ships that have changed their speed at different points during the voyage to ensure better fuel efficiency.
The fuel that is consumed on a cruise is also a problem for environmentally conscious people. In addition to changing the cruising speed, some green cruise ships also use alternative energy sources. Some ships have been equipped with solar panels. Others are finding ways to use discarded cooking shortening as biodiesel. This not only recycles a product that otherwise becomes waste, but it’s also a cleaner fuel than regular diesel.
Some cruise ships are becoming more efficient by accepting cargo. When rooms on the ship are vacated by passengers, they are rented out as cargo holds. This helps maximize the utility of each trip and also helps cruise lines make some money on unsold rooms.
Some of the methods described above can be used to retrofit old cruise liners into more environmentally friendly vessels. There are other techniques, however, that are used when building all-new eco-friendly cruise ships. One of the key features of many new green cruise ships is the weight of the materials used to build them. By choosing lighter materials and reducing the overall weight of the boat, you reduce the amount of fuel needed to propel the boat.
