The Energy Controllers are devices created by the Luminoth during their Golden Age on Aether. Their main purpose is to regulate the planetary energy of Aether; this is necessary because Aether is a planet without a sun. They also control energy-related phenomena (such as weather) on the unstable planet. There are 4 Energy Controllers on Aether, each stored within the depths of a Luminoth Temple. Energy Controllers hold a reservoir of stored energy above the control unit that appears as a large sphere of light. 3 of the Energy Controllers in the lesser Luminoth Temples direct a portion of this energy in the form of beams of light to the Controller in the Great Temple.
When a Phazon-bearing asteroid crashed into the planet and created Dark Aether, the energy was split between the two worlds, and both became unstable. During the war between the Luminoth and the Ing, most of the planetary energy was stolen by the Ing in an attempt to destroy Light Aether. However, when Samus became bonded with the Energy Transfer Module, she successfully returned all the energy to Light Aether, resulting in the dark planet's destruction.
