The terms wind energy, or wind power, describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical

The concept of using wind energy for grinding grain spread rapidly through the Middle East and was in wide use long before the first windmill appeared in Europe. Starting in the 11th century A.D., European Crusaders brought the concept home with them, and the Dutch-type windmill most of us are familiar with was born. ... Instead of a tower, it ...

Wind turbine designs have evolved over time to increase in size and efficiency, ultimately leading to greater generating capacity. The principle design of commercial turbines today are horizontal axis wind turbines consisting of a rotor with three fiberglass blades attached to a hub, which is itself attached to a central piece (the nacelle) that is mounted on a steel tower.

People used wind energy to propel boats along the Nile River as early as 5,000 BC. By 200 BC, simple wind-powered water pumps were used in China, and windmills with woven-reed blades were grinding grain in Persia and the Middle East. New ways to use wind energy eventually spread around the world.

A tower mill is a type of vertical windmill consisting of a brick or stone tower, on which sits a wooden 'cap' or roof, which can rotate to bring the sails into the wind.. This rotating cap on a firm masonry base gave tower mills great advantages over earlier post mills, as they could stand much higher, bear larger sails, and thus afford greater reach into the wind.
