Energy Conservation Measures (ECMs) are technologies and practices which conserve energy for core mission functions. The Great Green Fleet will feature the use of ECMs on ships and aircraft, and ashore. Some examples of ECMs include the following:
Shipboard Energy Dashboard: Provides real-time situational awareness of energy demand associated with equipment. This allows the crew to minimize a ship’s energy consumption and increase its efficiency while meeting system performance and reliability requirements.
Stern Flaps: Modifies the flow field under the ship’s hull to reduce drag and turbulence, thereby reducing overall hull resistance and saving fuel.
Short-Cycle Mission and Recovery Tanking (SMART): This in-flight refueling practice provides more efficient use of resources when operationally feasible, which allows a more effective use of resources directed toward training for the high end fight. Specifically, SMART reduces fuel dumping.
Solid State Lighting: Uses light-emitting diodes (LEDs) to save energy, especially when replacing incandescent fixtures or in colored lighting applications. LEDs also last longer than incandescent or fluorescent fixtures, reducing maintenance.
Thermal Management Control System (TMCS): Uses a centralized control system and smart programmable thermostats to provide appropriate heating and cooling for each compartment throughout a ship, reducing energy waste.
