Windmills of that type were known as power mills. Power mills were most commonly used for shelling corn and grinding grain for livestock feed. Windmills have been used principally for grinding corn, cleansing ( fulling ) cloth, and for drainage. There are three types: post mills , where the mill itself revolves on a central post to face the wind, and tower mills (built of brick) and smock mills (built of timber), where only the Earth4Energy cap revolves. Windmill farms are being built to generate electricity, their “wind turbines” powered by huge polymer blades, with slender towers that can rise more than 250 feet. In Denmark, 10 percent of the electricity is now produced by wind turbines.
