Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built by ...

Renewable Energy
Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and Renewable energy in developing countries, developing countries, where energy is often crucial in Human development (humanity), human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can heat pump, move heat or objects efficiently, and is clean at the point of consumption.

Thomas Edison
Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida, ...

Edison Electric Light Station
Holborn Viaduct power station, named the Edison Electric Light Station, was the world's first coal-fired power station generating electricity for public use. It was built at number 57 Holborn Viaduct in central London, by Thomas Edison's Edison Electric Light Company. The plant began running on 12 January 1882 , three years after the invention of the carbon-filament incandescent light bulb. It burnt coal to drive a steam turbine which drove a , generator which produced direct current (DC) at 110 volts. It initially lit 968 16-candle incandescent lamps to provide street lighting from Holborn Circus to St. Martin's Le Grand, which was later expanded to 3,000 lamps. The power station also provided electricity for private residences, which may have included nearby Ely Place. Having run at a significant loss the station closed in September 1886, and the lamps were converted back to gas. Edison opened a second coal-fired power station in September 1882 in the United States, at Pe ...

Coal-fired Power Station
A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity. Worldwide, there are about 8,500 coal-fired power stations totaling over 2,000 gigawatts capacity. They generate about a third of the world's electricity, but cause many illnesses and early deaths, mainly from air pollution. A coal-fired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coal-fired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators. Thus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy. Coal-fired power stations emit over 10 Gt of carbon dioxide each year, about one fifth of world greenhouse gas emissions, so are the single largest cause of climate change. More than half of all the coal-fired electricity in the world is generated in ...

Dynamo
"Dynamo Electric Machine" (end view, partly section, ) A dynamo is an electrical generator that creates direct current using a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a mechanical commutator. Also, converting alternating to direct current using rectifiers (such as vacuum tubes or more recently via solid state technology) is effective and usually economical. History Induction with permanent magnets The Faraday disk was the first electric generator. The horseshoe-shaped magnet ''(A)'' created a magnetic field through the disk ''(D)''. When the disk was turned, this induced an elec ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and English la ...

Cragside
Cragside is a Victorian country house near the town of Rothbury in Northumberland, England. It was the home of William Armstrong, 1st Baron Armstrong, founder of the Armstrong Whitworth armaments firm. An industrial magnate, scientist, philanthropist and inventor of the hydraulic crane and the Armstrong gun, Armstrong also displayed his inventiveness in the domestic sphere, making Cragside the first house in the world to be lit using hydroelectric power. The estate was technologically advanced; the architect of the house, Richard Norman Shaw, wrote that it was equipped with "wonderful hydraulic machines that do all sorts of things". In the grounds, Armstrong built dams and lakes to power a sawmill, a water-powered laundry, early versions of a dishwasher and a dumb waiter, a hydraulic lift and a hydroelectric rotisserie. In 1887, Armstrong was raised to the peerage, the first engineer or scientist to be ennobled, and became Baron Armstrong of Cragside. The original building co ...

William Armstrong, 1st Baron Armstrong
William George Armstrong, 1st Baron Armstrong, (26 November 1810 – 27 December 1900) was an English engineer and industrialist who founded the Armstrong Whitworth manufacturing concern on Tyneside. He was also an eminent scientist, inventor and philanthropist. In collaboration with the architect Richard Norman Shaw, he built Cragside in Northumberland, the first house in the world to be lit by hydroelectricity. He is regarded as the inventor of modern artillery. Armstrong was knighted in 1859 after giving his gun patents to the government. In 1887, in Queen Victoria's golden jubilee year, he was raised to the peerage as Baron Armstrong of Cragside. Early life Armstrong was born in Newcastle upon Tyne at 9 Pleasant Row, Shieldfield, about a mile from the city centre. Although the house in which he was born no longer exists, an inscribed granite tablet marks the site where it stood. At that time the area, next to thPandon Dene was rural. His father, also called William, was ...

Zénobe Gramme
Zénobe Théophile Gramme (4 April 1826 – 20 January 1901) was a Belgian electrical engineer. He was born at Jehay-Bodegnée on 4 April 1826, the sixth child of Mathieu-Joseph Gramme, and died at Bois-Colombes on 20 January 1901. He invented the Gramme machine, a type of direct current dynamo capable of generating smoother (less AC) and much higher voltages than the dynamos known to that point. Career Gramme was poorly educated and semi-literate throughout his life. His talent was in handicraft and when he left school he became a joiner. After moving to Paris he took a job as a model maker at a company that manufactured electrical equipment and there became interested in technology. Having built an improved dynamo, Gramme, in association with Hippolyte Fontaine, opened a factory to develop the device. The business, called Société des Machines Magnéto-Électriques Gramme, manufactured the Gramme dynamo, Gramme ring, Gramme armature and other devices. In 1873 a Gramme ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.
