Energy
To answer a common question about energy APIs: If you just search the API that is most commonly used because you want to support most other energy-using mods, your best bet is TechReborn. However, this will lead to balancing issues because different mods use different approaches on how much energy something costs. So if you care about balancing, or if you want to protect your energy system from other mods, or if you simply do not care about inter-mod operability, have a look at the other options and choose the one that fits your needs.
