A study completed in 1945 suggested that a block of six turbines similar to the prototype, producing 9 MW, could be installed in Vermont for around US$190 per kilowatt. However, the economic value to the power utility was only $125 per kilowatt, and the wind turbine was not considered economically viable by a factor of 1.5. [10]
Wind Power Density (WPD) is a quantitative measure of wind energy available at any location. It is the mean annual power available per square meter of swept area of a turbine, and is calculated for different heights above ground. Calculation of wind power density includes the effect of wind velocity and air density. [25]
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.
Wind power is considered a sustainable, renewable energy source, and has a much smaller impact on the environment compared to burning fossil fuels. Wind power is variable, so it needs energy storage or other dispatchable generation energy sources to attain a reliable supply of electricity. Land-based (onshore) wind farms have a greater visual ...

India has the fifth largest installed wind power capacity in the world. [96] As of 31 March 2014, the installed capacity of wind power was 21136.3 MW mainly spread across Tamil Nadu state (7253 MW). [97] [98] Wind power accounts nearly 8.5% of India's total installed power generation capacity, and it generates 1.6% of the country's power.
The Block Island Wind Farm was conceived as a larger project extending into neighboring Massachusetts [13] to build a $1.5-billion, 385-megawatt wind farm in federal waters. The 100-turbine project could provide 1.3 terawatt-hours (TW·h) of electricity per year – 15 percent of all electricity used in the state. [ 14 ]
Installed wind power capacity in Washington has seen strong growth in recent years and Washington now ranks among the top ten states with the most wind power installed. Wind power accounted for 5.3% of total electricity generated in Washington during 2011. [13] The table below shows the growth in wind power installed nameplate capacity in MW ...
