The gateway technology behind the tree.
Speeds all research by 2.5% per level and opens major propulsion, weapons and power branches.
Energy Technology is both a dependency hub and a permanent research-speed multiplier. Early levels open whole branches; later levels shorten every future project.
Combustion and Impulse Drives, Fusion Plant, laser and plasma chains, Hyperspace and Graviton research.
⚡ Prerequisite for advanced ships, defenses and research.
Research time depends on the Research Laboratory level, the Intergalactic Research Network and the universe speed.
Each level multiplies the previous cost by ×2, so each further level gets steadily more expensive the further you push it.
