Efficiency module
Note that minimal energy usage is 20% of base energy usage, so 3 efficiency modules would satisfy that. However, using more than 80% worth of efficiency modules makes sense if other modules are used, as they increase power usage and that effect is additive with the decrease from efficiency modules.
