Non-renewable resource

A non-renewable resource (as opposed to a renewable resource) is a resource that cannot be obtained in indefinite quantities in Survival without exploring more terrain or using certain glitches, commands or Creative mode to create more of them. While running out of resources other than the unique dragon egg is not likely to be a factor in normal gameplay due to massive size of a Minecraft map, in principle there is a finite quantity of these resources available in each Minecraft world.

Obtaining
Non-renewable resources can be obtained through crafting recipes that consume other non-renewable items, found as naturally generated blocks, obtained from structure loot chests or as drops from certain enemies that do not respawn (elder guardians and piglin brutes).

Some resources are non-renewable or even unobtainable if playing on Peaceful difficulty, as monsters do not spawn.

The degree of impact the non-renewability of a resource has on normal gameplay generally depends on how limited the resource is, but on custom maps these relationships may be changed; for example, on many Skyblock-style maps, any diamonds provided are extremely valuable, as no more can be obtained.

All status effects and enchantment-item combinations that cannot be obtained in Survival are non-renewable.

Generated structures
These non-renewable resources are found only as loot from generated structures, the blocks the structures are composed of, or as non-renewable drops from mobs which generate with the structures, and cannot be obtained in other ways unless using certain glitches, commands or Creative mode. This renders most of them unavailable in worlds with the "Generate Structures" option disabled. These resources are generally the most finite resources in the game, though some like cobwebs are relatively common.

Enchantments on items without prior-work anvil penalty
While all enchantments obtainable in Survival are renewable, for treasure enchantments the only renewable way to get them on most items is by using an anvil to combine the item with a renewable enchanted book. Using an anvil in this way causes the item to gain prior work penalty, increasing the cost of future anvil use. Similar limitations apply to some high level enchantments, which cannot be renewably obtained on items with insufficient enchantability without using an anvil.

This renders most types of items that have at least one of these enchantments without having any prior-work penalty non-renewable. Many of these item variants are unobtainable in Survival, but some of them can be found in the loot chests of various generated structures.

Items in bastion remnant, ruined portal and shipwreck loot chests are limited to one enchantment, while items from end city chests often have multiple.

Other
These non-renewable resources can be obtained from the world outside generated structures, they are generally more abundant, but some may be hidden under other blocks, making them harder to find. Since they generate outside structures, they can be found even in worlds with the generate structures option disabled.

Not obtainable in Survival
These resources are not obtainable as items in Survival. However, they can be encountered as blocks and some even created or manipulated in Survival.

Not encountered in Survival
These resources cannot be accessed, even as blocks, without using Creative mode or commands.

Bedrock Edition
These resources are not renewable in, even though they are in.

These items are non renewable in, and are not items at all in.

Java Edition
These resources are not renewable in, even though they are in the.

These items are non renewable in, and are not items at all in.

Peaceful difficulty
These resources are not renewable while playing in Peaceful difficulty as their renewable methods of obtaining require the spawning of hostile mobs. (Previously mentioned non-renewable resources are removed from the products list).

$$, Piglins still spawn in Peaceful difficulty. By killing piglins, the player can sometimes obtain golden swords, then smelt them into gold nuggets. This makes gold renewable, along with all items obtainable via bartering.

Going to the End almost always requires the use of eyes of ender, which are unobtainable in Peaceful difficulty, to activate the end portal, with the chances of requiring none being only 1 in a trillion for each end portal. Therefore, resources exclusive to the End can also be considered unobtainable and therefore non-renewable in Peaceful difficulty.
