It's more likely that it involves Ruby and Sapphire's thermokinetic powers. Ruby's exothermic ability can be interpreted as the release of energy, while Sapphire's endothermic ability can be interpreted as the absorption of energy. Garnet would be combining them in various proportions at will to regulate an electrical reaction.
