The first windmills were used for grinding grain and pumping water. In ancient times, windmills were primarily used to grind grain into flour, providing an efficient method for food production. Later on, windmills were also used to pump water from wells and drain marshes.
Windmills can be used to pump water from a local river to the village where people live. Windmills can be used to generate electricity so people can see at night or keep warm in winter.
Windmills help people in many ways. In olden times they used it to grind wheat for bread. Now we mostly use it to harness the power of wind energy and converting that into electricity. In netherlands, they use windmills to pump water away thereby leaving land for urbanization. Even today, most of the netherlands is below sea level.
Irrigation systems such as irrigation ditches, channels and canals artificially supply dry land with water.A river is a system which supplies dry land with water naturally, not artificially.
I am sure some windmills were used to grind flour, however the majority were used a pumps to keep the land drained.
Mostly, to grind corn. In the Netherlands they were even then already used for water management and for turning swamp land into dry land.

Ummm . . . windmills use the wind to keep them turning. No biofuels are involved.
The Dutch put windmills all over the land to clear the water on the surface. Know they have lots of dyke's to keep the water out.

Traditionally windmills have been used to grind grain for flour. In some places they pump water, for instance to drain low lying land, which is why the Netherlands became famous for windmills.
Yes windmills take up to much land. it takes about 120 square meters per windmill, knowing that now, I believe we should stop windmills and start using solar panels. They are now making cheaper solar panels, so that more people can use solar panels and stop windmills.
They built windmills and plows
Holland (the Netherland) is a low country. Next to the Northsea and with lots of rivers the Netherlands has been dealing with water for centuries. Building dams to keep the water at bay for instance. The Netherlands has a windy climate and uses the wind through windmills to fight the water.
