# What is the most efficient wood based fuel?

Which form of wood is actually the most efficient in furnaces? I would appreciate if there is a descending list of efficiency.

This includes any thing that can be made from wood, including charcoal though if it requires another unit of fuel to make it, do subtract from its efficiency.

I am aware of the similar question that is the fuel ranking. However, this question is specifically asking for a least-input greatest-output analysis for wood-only materials, to minimize the resource cost of getting efficient furnace fuel.

Its also to resolve a common argument of sticks vs planks and sticks vs crafted alternative.

So as mentioned by Schism, this is a input vs output question.

• minecraft.wikia.com/wiki/Furnace_Fuel contains a table with this info, does that help? Commented Apr 13, 2015 at 15:36
• @KevinvanderVelden I can't agree; this question asks something different (I think). I'll try to make it clearer in my answer. Commented Apr 13, 2015 at 15:39
• Yeah, I'm looking for a better fit, I'm sure it's been posted somewhere around here.

• I think with a little bit of editing, this could be a different question entirely - rather than asking for an order of least-resources to most-output, it's asking for greatest output vs. least initial resources used. Though mathematically they are similar. Commented Apr 13, 2015 at 16:57
• I can see the difference clearly now, but I couldn't at first. I urge future close voters to read both questions twice before casting their vote. The other question asks "How long will each item burn?" Answers to the other question are measured in seconds. This question asks "What is the most efficient item to burn?" Answers to this question are measured in seconds per unit of wood. If the two questions are the same, then why do the answers use different units? Commented Apr 13, 2015 at 19:41

The cost is calculated by assuming one Wood costs 24 (to avoid bad decimals). Planks therefore cost 6 (since one Wood makes four Planks), and Sticks cost 3 (since we make four sticks from two planks, or half a Wood per four-stack, making an eighth of a Wood per individual stick).

Charcoal is the most efficient, but it's kind of special. We need to kick off charcoal by first burning something else. This is in the table as `Charcoal*`. (See discussion in A word on Sticks vs Planks.) After that, we just use 1/8th of a Charcoal to make the rest of our Charcoal. This follows the progression cn+1 = 24 + cn/8. As n approaches infinity, the cost approaches `192/7`, which is in the table as `Charcoal (∞th)`.

Time is the time in seconds that an item will burn for. (It takes 10 seconds to smelt a single item.) Cost is as described above. Value is `Time / Cost * 24 / 10`, or the number of items you can expect to smelt using 1 Wood's worth of that item.

Note: Fences are crafted with 6 sticks for 2 fences on Console. On PC, we craft 4 planks and 2 sticks to make 3 fences. The Console recipe is slightly more efficient, causing a split in the table.

### A word on Sticks vs Planks

From the table, using Wooden Planks is clearly more efficient than using Sticks. However, this is not true if we're interested in bulk-smelting Charcoal.

In theory, it would be superior to use Planks -- after all, they are more efficient than Sticks. However, in practice, there's no point to crafting the other two Charcoal at reduced value. This means that in practice, the Plank we use for the first Charcoal is really only worth 10 seconds of smelting time, giving it the same efficiency as that of Sticks.

We can calculate this: using Planks to make 3 Charcoal gives us a value of `6.857(3) + 7(n - 3)`, where `n` is the amount of Charcoal we'll end up using. By making only one Charcoal, we get a cost of 30 for the first Charcoal, giving us `6.4 + 7(n - 1)`, whether we use Sticks or Planks. However, for any positive, integer value of `n` (which comprise all valid values), the second expression is greater than the first. It is always better to craft only one Charcoal. Therefore, when crafting Charcoal, it doesn't matter whether you use Sticks or Planks.

tl;dr Planks are better than Sticks if you're directly using them as fuel. However, if you're making Charcoal, then they're equally good.

• @DarkDestry The answer already clearly illustrates that sticks are worse off than planks. Sticks have a value of 4 while planks have a value of 6. Commented Apr 13, 2015 at 17:12
• @Rainbolt I can see that. However to facilitate easier reading, a final conclusion can be stated or perhaps tl;dr. Either way, It works for me. Just making a suggestion so i can arrow people that make the mistake to this answer. Commented Apr 13, 2015 at 17:14
• @Rainbolt It could be perhaps due to me being used to writing reports. The conclusion of this table with regards to one of the objective which is planks vs sticks should be shown clearly. Commented Apr 13, 2015 at 17:18
• @DarkDestry For the old fence recipe (6 sticks = 2 fence), you'd be right. The new recipe for fence is 4 planks + 2 sticks = 3 fence. Commented Apr 13, 2015 at 17:27
