Minecraft wiki entry for Survival_in_an_infinite_desert, associated text: A small amount of wood for fuel can be obtained by breaking the furniture inside village houses. It's not advisable to burn doors, but the functions of fences (which the furniture drops when it breaks, along with oak pressure plates or jungle button) can be replaced by other much more plentiful blocks (sand walls for example, or sandstone walls with sandstone slabs for "windows"). The pressure plates might be worth hanging on to in case you want to automate some doors or traps. The highest priority on fuel is definitely to smelt iron ore. Be careful to exactly calculate the burning time of each precious wooden item, and feed the next type of item into the furnace as soon as the fuel slot is empty.
