I'm from the netherlands and I always learned that those cute windmills were to grind grains for flow, spices, oil and water. Not only water. You should look inside one, it has a big round grinder and that's why wind is needed.
There are over 30 types of windmills for over 30 purposes. The most common ones are/were used for grains and spices.
