Fabric Energy API
A API that provides a simple and standardized way to handle energy in Fabric.
About this Mod
Fabric Energy API
Why?
Very annoying that every modpack for Fabric uses its own library and reimplementation of a energy system, meanwhile forge has a standardized API that makes most (if not all) mods cross compatible, while Fabric is stuck with energy mods that need specific compatibility mods, and its just a general mess.
This project wants to solve that. By creating a simple, fast, and modern energy API to hopefully one day become the gold standard for fabric, making energy a standard and cross compatible spec.
How it works.
We have a unit called Fabric energy (Or just FE for short), which is calculated every single tick, similar to how Forge energy works. (FE/t)
For the API spec visit the github repo.
Notes
Users, this mod adds no actual content, its a API for developers.
For mod developers, this api is on both Modrinth and Curseforge, so no need to worry about platform exclusivity.

Server lagging with Fabric Energy API – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Fabric Energy API consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
