NASA Wind Turbines
Starting in 1975, NASA managed a program for the United States Department of Energy and the United States Department of Interior to develop utility-scale wind turbines for electric power, in response to the increase in oil prices. A number of the world's largest wind turbines were developed and tested under this pioneering program. The program was an attempt to leap well beyond the then-current state of the art of wind turbine generators, and developed a number of technologies later adopted by the wind turbine industry. The development of the commercial industry however was delayed by a significant decrease in competing energy prices during the 1980s. Program origin In 1974, partially in response to the increase in oil price after the 1973 oil crisis, the Energy Research and Development Administration (ERDA), later part of United States Department of Energy, appointed a department under the direction of Louis Divone to fund research into utility-scale wind turbines.

Wind Generator Comparison
Wind is the natural movement of atmosphere of Earth, air or other gases relative to a planetary surface, planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption (electromagnetic radiation), absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their scale (spatial), spatial scale, their speed and direction, the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Farm
A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used Wind power, to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore. Many of the largest operational onshore wind farms are located in China, India, and the United States. For example, the List of onshore wind farms, largest wind farm in the world, Gansu Wind Farm in China had a capacity of over 6,000 megawatt, MW by 2012,Watts, Jonathan & Huang, CecilyWinds Of Change Blow Through China As Spending On Renewable Energy Soars ''The Guardian'', 19 March 2012, revised on 20 March 2012.

American Wind Energy Association
The American Wind Energy Association (AWEA) is a Washington, D.C.–based national trade association formed in 1974, representing wind power project developers, equipment suppliers, service providers, parts manufacturers, utilities, researchers, and others involved in the wind industry. AWEA promotes wind energy as a clean source of electricity for consumers in the U.S. and around the world and has around 1,000 member organizations. The group was succeeded in January 2021 by the American Clean Power Association. Legislative efforts AWEA staff lobby the U.S. Congress to promote policies encouraging investment in wind energy and provide statistics and data on the wind industry. Additionally, they make policy recommendations and testify on various issues. AWEA supports policies which it asserts will generate investment in the U.S. economy, improve U.S. energy security, and slow climate change, including extension of the federal Production Tax Credit (PTC) and Investment Tax Cre ...

EDF Energies Nouvelles
EDF Renewables (formerly ''EDF Renouvelables'') is a wholly owned subsidiary of the French utility EDF Group, specializing in renewable energy production. As an integrated operator, the Group develops and finances the construction of renewable energy facilities, and manages operations and maintenance for its own account and for third parties. According to its own figures, the company is active in 22 countries with an installed global capacity of 12,468 MW (as of June 2019), with wind being the largest sector, followed by solar and energy storage. The company is also involved in marine energy. The company was formerly known as EDF Energies Nouvelles until it was rebranded in April 2018 to its current name, EDF Renewables. History In 1990, the Société Internationale d'Investissements Financiers – Énergies (SIIF Énergies) was created by Pâris Mouratoglou, a thermal and hydroelectric power plant development company. The firm in 1999 positioned itself in the renewable ener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

REpower
Senvion S.A. (called REpower Systems SE until 2014) was a German wind turbine manufacturer founded in 2001 in Germany, majority owned by a private equity firm. Senvion as REpower Systems, as it was initially called, was established in 2001 through the merger of German wind companies: HSW (Husumer Schiffswerft), the engineering consultancy Pro+Pro (a subsidery of Denker&Wulf and aerodyn Energiesysteme GmbH), the wind turbine manufacturer BWU and Jacobs Energie; and since April 2015 Centerbridge Partners. It was under the ownership of Suzlon, an India wind turbine manufacturer, from 2007 to 2015. With equipment pricing under pressure due to auctions, Senvion filed for insolvency in German courts in early April 2019. Senvion sold its 9 GW European service fleet to Siemens Gamesa in October 2019. A Saudi Arabia company acquired the India division of Senvion in 2021.

Groundbreaking
Groundbreaking, also known as cutting, sod-cutting, turning the first sod, or a sod-turning ceremony, is a traditional ceremony in many cultures that celebrates the first day of construction for a building or other project. Such ceremonies are often attended by dignitaries such as politicians and businesspeople. The actual shovel used during the groundbreaking is often a special ceremonial shovel, sometimes colored gold, meant to be saved for subsequent display and may be engraved. In other groundbreaking ceremonies, a bulldozer is used instead of a shovel to mark the first day of construction. In some groundbreaking ceremonies, the shovel and the bulldozer mark the first day of construction. Meaning When used as an adjective, the term groundbreaking may mean being or making something that has never been done, seen, or made before; "stylistically innovative works". History Groundbreaking ceremonies have been celebrated for centuries in an attempt to begin the construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
