67 Phoenix Reisen says it has already done a great deal to reduce energy consumption on ships. “The continuous renewal of air conditioning systems and the replacement of conventional lamps with modern, energy-efficient LED lamps with different switching options are just as much a part of this as the successive installation of a central light/power shutdown system in all passenger cabins (sockets, refrigerators and TV programming systems remain unaffected, of course). The replacement of the refrigerators in the cabins with appliances with improved energy efficiency class has also provided great energy-saving potential.” On luxury vessel The World, energy-saving interventions include “the replacement of refrigerator compressors with more efficient machines, upgrading to new dishwashers that use less water, installing LED lighting, implementing ‘smart’ HVAC controls, and capturing and repurposing waste heat from engine cooling water systems.” TUI Cruises lists among the technologies it invests in for its fleet: “Efficient air conditioning, Innovative lighting controls, comprehensive LED concept.”
