Welcome to Survival Essentials Pack: Renewables!
This pack adds or changes various aspects of Survival gameplay that I felt were lacking or underutilized. These changes have been made with balanced gameplay in mind while also keeping everything as "vanilla" as feasible.

SEP: Renewables focuses on correcting the existing blocks and items that are finite or unnecessarily difficult to obtain.

Versions

The main download is for 1.21 -> 1.21.4. See the Github link for versions before this.
The current version is designed for Singleplayer. Multiplayer is untested, but should work.
