How to farm charcoal efficiently for fuel

Charcoal as a renewable fuel source

Unlike coal, charcoal is renewable—you can produce it by smelting wood in a furnace. This makes it ideal for long-term fuel sustainability.

Creating a charcoal supply

Smelt wood logs in a furnace to produce charcoal. Once you have charcoal, you can craft it into tiny charcoal for single-item smelting or combine nine pieces into a charcoal block for bulk operations.

Scaling production

Set up multiple furnaces dedicated to charcoal production. Feed them wood and fuel them with your existing coal or charcoal reserves. As your charcoal stockpile grows, you'll have a self-sustaining fuel cycle.

Optimization tips

Use charcoal blocks when you've accumulated nine or more pieces—the 10% efficiency bonus makes them worthwhile for sustained smelting. Keep tiny charcoal available for small jobs so you never waste a full piece of fuel. With renewable charcoal production, you can smelt indefinitely without relying on limited coal deposits.
