| Energy | The standard Energy API created and used by Team Reborn | Team Reborn, modmuss50 |
| LibPow | Flavoured energy API designed for flexibility | enderger |
To answer a common question about the Energy API: If you are just looking for the API that is most commonly used because you want to support most other energy-using mods, you should use TechReborn Energy. However, this can lead to balancing problems because different mods take different approaches to how much power something costs. So if you care about balancing, or if you want to protect your energy system from other mods, or if you just don't care about working capacity between mods, take a look at the other options and choose the one that suits your needs.
