A wind turbine , or wind energy converter , is a device that converts the wind's kinetic energy into electrical energy. Wind turbines are manufactured in a wide range of sizes, with either horizontal or vertical axes. There are Gigawatt in hundreds of thousands of large turbines , known as wind farms , with 60 GW added per year. One assessment claimed that, as of [update] , wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and Larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. The windwheel of Hero of Alexandria 10 AD — 70 AD marks one of the first recorded instances of wind powering a machine in history.

Ditkovich, A. Three approaches to calculating capacity factor of fixed speed wind turbines are reviewed and compared using a case study. The latter approach, while being an approximation, can be solved analytically thus providing a valuable insight into aspects, affecting the capacity factor. Moreover, several other merits of wind turbine performance may be derived based on the analytical approach. It is shown that the results obtained by employing the three approaches are very close, enforcing the validity of the analytically derived approximations, which may be used for wind turbine performance evaluation.
Wind power as a source of green and abundant energy is proposed as one of the main new world power sources and has acquired a great momentum across the world. In the last few decades, wind turbines with different generators have been developed to increase the maximum power capture, minimize the cost, and expand the use of the wind turbines in both onshore and offshore applications. This paper reviews the development of different types of wind turbine generator technologies and discusses advantages and disadvantages of each type. In addition, a comparison of different generator designs based on the technical data and market trends is provided. To better understand the development of generator concepts on the market, the market trends of current large generators with a capacity of 2. In recent years, implementing renewable energies has moderate to strong support across the world.
In recent years, Brazilian wind energy has been growing on a fast trajectory, with the prospect of being the second main source of energy in the year after hydroelectricity. It should be reaching an installed capacity of more than 20 GW by In this context, this work presents the evolution and the current scenario of wind energy in Brazil, bringing a discussion on the issues surrounding wind energy and the environmental, social and economic pillars of the sustainability. Rotor-blade manufacturing methods and composite materials recycling after the turbine lifetime are considered. Construction, operation and maintenance aspects of wind turbines are also discussed.
Компания Ай-би-эм предоставила ему визу и предложила работу в Техасе. Танкадо ухватился за это предложение.
Он сказал, что выгравированные буквы выглядят так, будто кошка прошлась по клавишам пишущей машинки. - Коммандер, не думаете же вы… - Сьюзан расхохоталась. Но Стратмор не дал ей договорить. - Сьюзан, это же абсолютно ясно.
За дверью. - Да, конечно… сэр. - Сьюзан не знала, как. Бросила взгляд на монитор, потом посмотрела на Грега Хейла.
Она сомневалась, что Танкадо мог передать ключ какому-то человеку, который не приходился ему близким другом, и вспомнила, что в Штатах у него практически не было друзей. - Северная Дакота, - вслух произнесла она, пытаясь своим умом криптографа проникнуть в скрытый смысл этого имени.
