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.
In the United Kingdom, a project will trial cutting blades into strips for use as rebar in concrete, with the aim of reducing emissions in the construction of High Speed 2. [111] Used wind turbine blades have been recycled by incorporating them as part of the support structures within pedestrian bridges in Poland [112] and Ireland. [113]
In this nation more than others, "windmill" is often used to refer to what are properly termed windpumps bringing up water for agriculture. This is at least partly due to usage by windpump builders Eclipse Windmill Company (1873) and Aermotor Windmill Company (1888, the sole surviving US "windmill" manufacturer [ 1 ] ).

Wind turbines small enough to be held by a single steel pipe are often secured with scaffold base plate mounted to a concrete foundation. A hinged design allows easy lowering for maintenance. Small wind turbines must reach a certain wind speed, called the cut-in speed, to start generating electricity.
The broken windmill isn’t turning, which means that Sunny Field Farm has no power. The broken windmill needs to turn again so Zee can launch his rocket. The Mechas need to fix the broken windmill blade to get it working again. The Mechas help out Izzy and Timmy with their Rube Goldberg-inspired bird caller for Grandma.
A diagram of a panemone whose wind-catching panels are arranged to turn edge-on to the wind when moving against the wind's thrust, and side-on when moving downwind to harness the wind's motion. A panemone windmill is a type of vertical-axis wind turbine. It has a rotating axis positioned vertically, while the wind-catching blades move parallel ...
