Further, raw biomass (for instance wood chips) can have higher moisture content than coal (especially if the coal has been dried). When this is the case, more of the wood's inherent energy must be spent solely on evaporating moisture, compared to the drier coal, which means that the amount of CO 2 emitted per unit produced heat will be higher.
The moisture is decided by the handling of the raw material. If the trees are taken down in the winter and left to dry for the summer (with teas in the bark and covered so rain can't reach to them), and is then chipped in the fall, the woodchips' moisture content will be approximately 20–25%.

One of the age old techniques for food preservation, to avoid mold and fungus growth, is the process of drying out the food or dehydrating it.
