Hambach Open Pit Mine
The Tagebau Hambach is a large open-pit coal mine () in Niederzier and Elsdorf, North Rhine-Westphalia, Germany. It is operated by RWE and used for mining lignite. The mine is on the site of the ancient Hambach Forest, which was purchased by RWE in 1978. The company then cut most of the forest down and cleared it to mine. Only 10% of the forest area remains. RWE planned to clear half of the remaining area between 2018 and 2020. This plan was met with massive protests in the autumn of 2018 and was temporarily stopped in October 2018 by the supreme administrative court of North Rhine-Westphalia (Oberverwaltungsgericht für das Land Nordrhein-Westfalen). Having begun in 1978, the mine's operation area currently (as of end of 2017) has a size of 43.8 km2, with the total area designated for mining having a size of 85 km2. It is the deepest open pit mine in relation to sea level: the bottom of the pit, with up to from the surface, is below sea level, the deepest artifici ...

Neurath Power Station
Neurath Power Station is a lignite-fired power station near Neurath in Grevenbroich, North Rhine-Westphalia, Germany. It is located to the south of Grevenbroich, and it borders the municipalities of Rommerskirchen and Bedburg. The power station consists of seven units, of which two are currently operating, and it is owned by RWE. It was named the second biggest single emitter of carbon dioxide emissions in the European Union in 2019 by the EU's Transport and Environment Group, as well as the 102nd biggest polluting asset globally by Climate TRACE. Description The Neurath Power Station serves mainly as a base load power station. It consists of seven units (3 x 300 MW, 2 x 600 MW, and 2 x 1,100 MW nominally). The five older units were built between 1972 and 1976, and together had a gross electrical generation capacity of 2,200 MW. These units were decommissioned on 31 March 2024.

RWE Power AG
RWE AG is a German multinational energy company headquartered in Essen. It generates and trades electricity in the Asia-Pacific region, Europe and the United States. In July 2020, RWE completed a far-reaching asset swap deal with E.ON first announced in 2018, whereby the international renewable generation portfolio of E.ON and Innogy were transferred to RWE. History Pre-World War I The company was founded in Essen in 1898, as Rheinisch-Westfälisches Elektrizitätswerk Aktiengesellschaft (Rhenish-Westphalian Power Plant) by Elektrizitäts-Actien-Gesellschaft vorm. W. Lahmeyer & Company (EAG) and others. The full name was used until 1990 when it was renamed to RWE AG. Its first power station started operating in Essen in 1900. In 1902, EAG sold its shares to a consortium formed by Ruhr industrialists Hugo Stinnes and August Thyssen. In 1906, it expanded its operations beyond Essen by acquiring Elektrizitätswerk Berggeist AG in Brühl, and Bergische Elektrizitätswerke ...

Uwe Rau
Uwe Rau is a German physicist who made important contributions to the physics of the photovoltaic device, notably on explaining energy losses in thin-film solar cells and on the use of the reciprocity principle to characterize solar cells by electroluminescence techniques. This led to the development of this technique as a standard in research and industry. Career Rau studied physics at the University of Tübingen, Germany and the Université Claude Bernard, Lyon. Both his diploma thesis (1987) and his doctoral thesis (1991) were obtained for work performed in the group of Huebener, at the University of Tübingen, on the breakdown of Germanium under high magnetic fields, and for non-linear charge transport in semiconductors. He worked at the Max Planck Institute for Solid State Research in Stuttgart, where he worked on crystalline silicon solar cells. In 1995, he moved to Bayreuth where he predominantly worked on the device physics of solar cells. In 1997, he moved back to Stuttg ...

Gigawatts
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one newton, the rate at which 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 potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). \mat ...

Photovoltaic Power Station
A photovoltaic power station, also known as a solar park, solar farm, or solar power plant, is a large-scale grid-connected photovoltaic power system (PV system) designed for the supply of merchant power. They are different from most building-mounted and other decentralized solar power because they supply power at the utility level, rather than to a local user or users. Utility-scale solar is sometimes used to describe this type of project. This approach differs from concentrated solar power, the other major large-scale solar generation technology, which uses heat to drive a variety of conventional generator systems. Both approaches have their own advantages and disadvantages, but to date, for a variety of reasons, photovoltaic technology has seen much wider use. , about 97% of utility-scale solar power capacity was PV. In some countries, the nameplate capacity of photovoltaic power stations is rated in megawatt-peak (MWp), which refers to the solar array's theoretical maxim ...

Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing (electrical power), load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through water turbine, turbines to produce electric power. Pumped-storage hydroelectricity allows energy from Intermittent energy source, intermittent sources (such as solar power, solar, Wind power, wind, and other renewables) or excess electricity from continuous base-load sources (such as coal or nuclear) to be saved for periods of higher demand. The reservoirs used with pumped storage can be quite small, when contrasted with the lakes of conventional hydroelectric plants of ...

Sophienhöhe
The Sophienhöhe (301.8 m AMSL) is the largest artificial hill worldwide, created by surface mining at the open cast lignite mine Tagebau Hambach operated by RWE Power AG in Düren (district), North Rhine-Westphalia, Germany. Location Sophienhöhe is about 6 km east of the city centre of Jülich bordering Niederzier and Titz at the north-end of the open pit Tagebau Hambach. The distance (in respect to sea-level) between the top of Sophienhöhe and the lowest point of the pit is 594.8 meters. Tagebau Hambach is the lowest surface point in Europe, lying 293 meters below sea level. The CIA still maintains that Neuendorf bei Wilster is Germany's lowest point. The highest points of Sophienhöhe are Höller Horn (291.5 m AMSL), Jülicher Kopf (285.8 m AMSL) and the Roman Tower (301.8 m AMSL).
