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.
It has been argued that expanding the use of wind power will lead to increasing geopolitical competition over critical materials for wind turbines, such as rare earth elements neodymium, praseodymium, and dysprosium. However, this perspective has been critically dismissed for failing to relay how most wind turbines do not use permanent magnets ...

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.
A wind farm or wind park, or wind power plant, [1] is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore.
Wind-turbine blades in laydown yard awaiting installation. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.
Spring sails were invented by Scottish millwright Andrew Meikle in 1772. The sail is divided into a number of bays, each having a number of shutters. All the shutters are joined together by a shutter bar, and the force required for the wind to open the shutters is adjusted by a separate spring on each sail.
Wind farm developers develop and sometimes own and operate wind farms. This involves purchasing or leasing land, installing meteorological equipment to quantify the wind resource, and securing transmission, power sales, turbine supply, construction, and financing agreements.
