In addition, there is currently no competitive market for wind energy (though there may be in the future), because wind is a freely available natural resource, most of which is untapped. [116] The main cost of small wind turbines is the purchase and installation process, which averages between $48,000 and $65,000 per installation.
The Mod-1 was the first wind turbine in the world to produce 2 megawatts and also General Electric's first wind turbine. The Danish da:Vindkraftværket Tvindkraft with a hub height of 46 meters above the ground, a larger rotor and a rating at a higher wind speed, had a capacity of 2000 kW but never achieved 2 MW power output of the Mod-1.
An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, [1] thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, [2] or the need for slip rings or yaw mechanism. An electrical generator may be on the ground ...
The wind energy sector can also produce jobs during the construction and operating phase. [102] Jobs include the manufacturing of wind turbines and the construction process, which includes transporting, installing, and then maintaining the turbines. An estimated 1.25 million people were employed in wind power in 2020. [103]
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.

All four use General Electric 1.5SLE wind turbines. [6] The 112.5 MW Sheldon Wind Project in Wyoming County also came on line in 2009. In 2010, the Hardscrabble Wind Farm located in Herkimer County was constructed in the Towns of Farfield, Norway, and Little Falls, NY. The wind farm has 37 Gamesa G90 2.0 MW wind turbines and came online in 2011.
