GROWIAN
Growian or GROWIAN (short for German "Große Windenergieanlage" - "Large wind turbine") was a publicly funded wind turbine built in the Kaiser-Wilhelm-Koog near Marne for purposes of technology testing in the 1980s. It was a two-bladed "lee runner" (the rotor was situated on the downwind side of the tower) with a hub height of about . For a long time Growian was the world's largest wind turbine. Many features of the installation were novel and had not previously been trialled at this scale. Due to manufacturing faults in the casing, the turbine could not be run at full performance, and various issues with materials and construction prevented continuous testing. Consequently, the installation was idle for the greater part of the period between the first test run on 6 July 1983 (official start of operations was 4 October 1983) and end of operations in August 1987. Growian was decommissioned over the course of 1987, and dismantled in summer 1988. Technical data left, GROWIAN with ...

Schleswig-Holstein
Schleswig-Holstein (; da, Slesvig-Holsten; nds, Sleswig-Holsteen; frr, Slaswik-Holstiinj) is the northernmost of the 16 states of Germany, comprising most of the historical duchy of Holstein and the southern part of the former Duchy of Schleswig. Its capital city is Kiel; other notable cities are Lübeck and Flensburg. The region is called ''Slesvig-Holsten'' in Danish and pronounced . The Low German name is ''Sleswig-Holsteen'', and the North Frisian name is ''Slaswik-Holstiinj''. In more dated English, it is also known as ''Sleswick-Holsatia''. Historically, the name can also refer to a larger region, containing both present-day Schleswig-Holstein and the former South Jutland County (Northern Schleswig; now part of the Region of Southern Denmark) in Denmark. It covers an area of , making it the 5th smallest German federal state by area (including the city-states). Schleswig was under Danish control during the Viking Age, but in the 12th century it escaped full control ...

MAN SE
MAN SE (abbreviation of ''Maschinenfabrik Augsburg-Nürnberg'', ) was a manufacturing and engineering company based in Munich, Germany. Its primary output was commercial vehicles and diesel engines through its MAN Truck & Bus and MAN Latin America divisions, and participation in the manufacturer Sinotruk. MAN SE was majority-owned by Traton, the heavy commercial vehicle subsidiary of automaker Volkswagen AG, until August 2021 when Traton completed a squeeze out of all remaining shareholders and formally merged MAN SE into Traton SE, meaning the former subsidiaries of MAN SE were now directly owned by Traton, and MAN SE ceased to exist. History Foundation MAN traces its origins back to 1758, when the "St. Antony" ironworks commenced operation in Oberhausen, as the first heavy-industry enterprise in the Ruhr region. In 1808, the three ironworks "St. Antony", "Gute Hoffnung" (English: "Good Hope"), and "Neue Essen" (English: "New Forges") merged, to form the Hüttengewerks ...

Wind Farms In Germany
Wind is the natural movement of air or other gases relative to a 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 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 spatial scale, their speed and direction, the forces that cause them, the regions in which they occur, and their effect. Winds have various asp ...

Small Wind Turbine
Small wind turbines, also known as micro wind turbines, are used for microgeneration of electricity, as opposed to large commercial wind turbines, such as those found in wind farms. Small wind turbines often have passive yaw systems as opposed to active ones. They use a direct drive generator and use a tail fin to point into the wind, whereas larger turbines have geared powertrains that are actively pointed into the wind. Small wind turbines typically produce between 500 W and 10 kW of power, although the smaller turbines may be as small as a 50 Watt auxiliary power generator for a boat, caravan, or miniature refrigeration unit, and the Canadian Wind Energy Association (CanWEA) defines "small wind" as high as 300 kW. The IEC 61400 Standard defines small wind turbines as wind turbines with a rotor swept area smaller than 200 m2, generating at a voltage below 1000 Va.c. or 1500 Vd.c. Design Blades Smaller scale turbine blades are usually in diameter and produce 0.5-10 ...

Repowering
Repowering is the process of replacing older power stations with newer ones that either have a greater nameplate capacity or more efficiency which results in a net increase of power generated. Repowering can happen in several different ways. It can be as small as switching out and replacing a boiler, to as large as replacing the entire system to create a more powerful system entirely. There are many upsides to repowering. The simple act of refurbishing the old with the new is in itself beneficial alongside the cost reduction for keeping the plant running. With less costs and a higher energy output, the process is excessively beneficial. Examples Wind power Repowering a wind farm means replacing older, generally smaller, wind turbines with newer, generally larger, and more efficient designs. New innovations in wind power technology have dramatically increased the power output of new turbines compared with older designs. By repowering old wind turbines with new upgrades, the incr ...

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.

Offshore Wind Power
Offshore wind power or offshore wind energy is the generation of electricity through wind farms in bodies of water, usually at sea. There are higher wind speeds offshore than on land, so offshore farms generate more electricity per amount of capacity installed.Madsen & KrogsgaardOffshore Wind Power 2010 ''BTM Consult'', 22 November 2010. Retrieved: 22 November 2010. Offshore wind farms are also less controversial than those on land, as they have less impact on people and the landscape. Unlike the typical use of the term "offshore" in the marine industry, offshore wind power includes inshore water areas such as lakes, fjords and sheltered coastal areas as well as deeper-water areas. Most offshore wind farms employ fixed-foundation wind turbines in relatively shallow water. As of 2020, floating wind turbines for deeper waters were in the early phase of development and deployment. As of 2020, the total worldwide offshore wind power nameplate capacity was 35.3 gigawatt (GW). Unite ...

History Of Wind Power
Wind power has been used as long as humans have put sailing ships, sails into the wind. For more than two millennia Windmill, wind-powered machines have ground grain and pumped water. Wind power was widely available and not confined to the banks of fast-flowing streams, or later, requiring sources of fuel. Wind-powered pumps drained the Polder#Polders and the Netherlands, polders of the Netherlands, and in arid regions such as the American mid-west or the Australian outback, wind pumps provided water for livestock and steam engines. With the development of electric power, wind power found new applications in lighting buildings remote from centrally-generated power. Throughout the 20th century parallel paths developed small wind plants suitable for farms or residences, and larger utility-scale wind generators that could be connected to electricity grids for remote use of power. Today wind-powered generators operate in every size range between tiny plants for battery charging at is ...

Gesellschaft Mit Beschränkter Haftung
A ''Gesellschaft mit beschränkter Haftung'' (, abbreviated GmbH and also GesmbH in Austria; ) is a type of legal entity common in Germany, Austria, Switzerland (where it is equivalent to a ''société à responsabilité limitée''), and Liechtenstein. It is an entity broadly equivalent to the private limited company in the United Kingdom and many Commonwealth countries, and the limited liability company (LLC) in the United States. The name of the GmbH form emphasizes the fact that the owners (''Gesellschafter'', also known as members) of the entity are not personally liable or credible for the company's debts. GmbHs are considered legal persons under German, Swiss, and Austrian law. Other variations include mbH (used when the term ''Gesellschaft'' is part of the company name itself), and gGmbH (''gemeinnützige'' GmbH) for non-profit companies. The GmbH has become the most common corporation form in Germany because the AG (''Aktiengesellschaft''), the other major company form ...
