The windmills at Kinderdijk in the village of Kinderdijk, Netherlands is a UNESCO World Heritage Site. A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, by tradition specifically to mill grain (), but in some parts of the English-speaking world, the term has also been extended to encompass windpumps, wind turbines, and other applications.
Windmills in general had been known to civilization for centuries, but the tower mill represented an improvement on traditional western-style windmills. The tower mill was an important source of power for Europe for nearly 600 years from 1300 to 1900, contributing to 25 percent of the industrial power of all wind machines before the advent of ...
Offshore Horizontal Axis Wind Turbines (HAWTs) at Scroby Sands Wind Farm, England Onshore Horizontal Axis Wind Turbines in Zhangjiakou, Hebei, China. Large three-bladed horizontal-axis wind turbines (HAWT) with the blades upwind of the tower (i.e. blades facing the incoming wind) produce the overwhelming majority of wind power in the world ...
During the nineteenth and twentieth centuries, Dutch millwrights developed the windmill sail to make it more efficient aerodynamically and operation easier in an effort to keep the traditional windmill economically viable in competition with factories and electric pumping stations.
Brill windmill, a 17th-century post mill in Buckinghamshire. The post mill is the earliest type of European windmill. Its defining feature is that the whole body of the mill that houses the machinery is mounted on a single central vertical post. The vertical post is supported by four quarter bars. These are struts that steady the central post.
The smock mill is a type of windmill that consists of a sloping, horizontally weatherboarded, thatched, or shingled tower, usually with six or eight sides. It is topped with a roof or cap that rotates to bring the sails into the wind. This type of windmill got its name from its resemblance to smocks worn by farmers in an earlier period. [1]
Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails , windmills and windpumps , but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation.
This is a list of "traditional" windmills in the United States, which usually are gristmills. In this nation more than others, "windmill" is often used to refer to what are properly termed windpumps bringing up water for agriculture.
