What causes white smoke?

Smoke is the biproduct of the fuels it is burning. The color of the smoke indicates to firefighters the type and density of the fuels involved, all of which gives hints as to what the fire might do next. White smoke can often mean material is off-gassing moisture and water vapor, meaning the fire is just starting to consume material.
