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 ...
Nashtifan wind turbines in Sistan, Iran. The windwheel of Hero of Alexandria (10–70 CE) marks one of the first recorded instances of wind powering a machine. [5] However, the first known practical wind power plants were built in Sistan, an Eastern province of Persia (now Iran), from the 7th century.
Wind power is now one of the main sources of renewable energy, and its use is growing rapidly, driven by innovation and falling prices. [98] Most of the installed capacity in wind power is onshore, but offshore wind power offers a large potential as wind speeds are typically higher and more constant away from the coast. [99]
Wind power in Russia – Russia has a long history of small-scale wind power use, but the country has not yet developed large-scale commercial wind energy production. Wind power in Scotland – wind power is Scotland's fastest growing renewable energy technology, with 2,574 MW of installed capacity as of April 2011. Wind power in Serbia
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. Today, wind power is generated almost completely with wind turbines, generally grouped into wind farms and connected to the electrical grid.
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.
Danish toymaker Lego said in October that it will spend about $1.4 billion to build a wind farm off the coast of Germany. With the energy produced there, the company will be completely powered by renewable energy in under five years.
Wind power showed potential for replacing natural gas in electricity generation on a cost basis. By 2021 wind energy produced 4872 terawatts-hour, 2.8% of the total primary energy production [51] and 6.6% of the total electricity production. [52] Technological innovations continue to drive new developments in the application of wind power.
