Realistic Energy Industrial
Realistic Energy Industrial, published as REI, is a medium-sized Forge industrial mod for Minecraft 1.20.1 that mostly reuses the vanilla equipment and blocks.
What it does
Most of the content is built on existing vanilla equipment and pre-built blocks. Refined Iron, Refined Iron Ingot and Reinforced Ingot form the base of the progression, and crafting tools are made from Reinforced Ingot.
The mod changes parts of Minecraft's crafting and smelting behaviour. Smelting iron ore no longer produces an Iron Ingot straight away; it yields pig iron first, and smelting that again gives the Iron Ingot. The author notes describe much more content beyond these basics.
The mod is for Forge only and is published for 1.20.1 alone, with the latest file being 1.0.2 from 2026-02-22 on the beta channel. A server running it needs every connecting player to have it too. The source code is public, but the mod is licensed as All rights reserved and is not open source.
Key features
Refined iron materials
Refined Iron and Refined Iron Ingot are added as basic industrial materials for building further equipment.
Reinforced ingot tools
Crafting tools are made from Reinforced Ingot, placing a sturdier material early in the progression.
Altered iron smelting
Smelting iron ore yields pig iron first, and a second smelt turns it into an Iron Ingot.
Vanilla-based equipment
Most machines and blocks reuse vanilla equipment, so the mod extends existing parts instead of replacing them.
