Energy
Energy is used for several items and vehicles and is needed for them to operate. When energy runs out, the player can use a Battery or Power Cell (default R) to refill the energy. As of March 13, 2015 energy is implemented for the SeaGlide, Seamoth, Welder, Stasis Rifle, and Flashlight. The Cyclops and Base modules have energy requirements but do not drain energy from their Power Cells.
