182-737: A greenhouse gas . According to the World Commission on Dams report, where the reservoir is large compared to the generating capacity (less than 100 watts per square metre of surface area) and no clearing of the forests in the area was undertaken prior to impoundment of the reservoir, greenhouse gas emissions from the reservoir may be higher than those of a conventional oil-fired thermal generation plant. In boreal reservoirs of Canada and Northern Europe, however, greenhouse gas emissions are typically only 2% to 8% of any kind of conventional fossil-fuel thermal generation. A new class of underwater logging operation that targets drowned forests can mitigate
273-463: A low-head hydro power plant with hydrostatic head of few meters to few tens of meters can be classified either as an SHP or an LHP. The other distinction between SHP and LHP is the degree of the water flow regulation: a typical SHP primarily uses the natural water discharge with very little regulation in comparison to an LHP. Therefore, the term SHP is frequently used as a synonym for the run-of-the-river power plant . The largest power producers in
364-426: 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. However, when constructed in lowland rainforest areas, where part of
455-457: A diverse physical geography. It is low and flat near the North Sea coast and increasingly mountainous towards the northwest. Being in the far north of England, above 55° latitude , and having many areas of high land, Northumberland is one of the coldest areas of the country. But as the county lies on the east coast, it has relatively low rainfall, with the highest amounts falling on the high land in
546-421: A flood and fail. Changes in the amount of river flow will correlate with the amount of energy produced by a dam. Lower river flows will reduce the amount of live storage in a reservoir therefore reducing the amount of water that can be used for hydroelectricity. The result of diminished river flow can be power shortages in areas that depend heavily on hydroelectric power. The risk of flow shortage may increase as
637-520: A key role in the Industrial Revolution from the 18th century on. Many coal mines operated in Northumberland until the widespread closures in the 1970s and 1980s. Collieries operated at Ashington , Bedlington, Blyth , Choppington, Netherton, Ellington , and Pegswood . The region's coalfields fuelled industrial expansion in other areas of Britain, and the need to transport the coal from
728-809: A large natural height difference between two waterways, such as a waterfall or mountain lake. A tunnel is constructed to take water from the high reservoir to the generating hall built in a cavern near the lowest point of the water tunnel and a horizontal tailrace taking water away to the lower outlet waterway. A simple formula for approximating electric power production at a hydroelectric station is: P = − η ( m ˙ g Δ h ) = − η ( ( ρ V ˙ ) g Δ h ) {\displaystyle P=-\eta \ ({\dot {m}}g\ \Delta h)=-\eta \ ((\rho {\dot {V}})\ g\ \Delta h)} where Efficiency

Managing dams which are also used for other purposes, such as irrigation , is complicated. In 2021 the IEA called for "robust sustainability standards for all hydropower development with streamlined rules and regulations". Large reservoirs associated with traditional hydroelectric power stations result in submersion of extensive areas upstream of

A Pico-hydro setup is typically run-of-the-river , meaning that dams are not used, but rather pipes divert some of the flow, drop this down a gradient, and through the turbine before returning it to the stream. An underground power station is generally used at large facilities and makes use of
1547-455: A source of low-cost renewable energy. Alternatively, small hydro projects may be built in isolated areas that would be uneconomic to serve from a grid, or in areas where there is no national electrical distribution network. Since small hydro projects usually have minimal reservoirs and civil construction work, they are seen as having a relatively low environmental impact compared to large hydro. This decreased environmental impact depends strongly on
1638-414: A start-up time of the order of a few minutes. Although battery power is quicker its capacity is tiny compared to hydro. It takes less than 10 minutes to bring most hydro units from cold start-up to full load; this is quicker than nuclear and almost all fossil fuel power. Power generation can also be decreased quickly when there is a surplus power generation. Hence the limited capacity of hydropower units

Where a dam serves multiple purposes, a hydroelectric station may be added with relatively low construction cost, providing a useful revenue stream to offset the costs of dam operation. It has been calculated that the sale of electricity from the Three Gorges Dam will cover the construction costs after 5 to 8 years of full generation. However, some data shows that in most countries large hydropower dams will be too costly and take too long to build to deliver

The low greenhouse gas impact of hydroelectricity is found especially in temperate climates . Greater greenhouse gas emission impacts are found in the tropical regions because the reservoirs of power stations in tropical regions produce
3094-462: Is not an energy source, and appears as a negative number in listings. Run-of-the-river hydroelectric stations are those with small or no reservoir capacity, so that only the water coming from upstream is available for generation at that moment, and any oversupply must pass unused. A constant supply of water from a lake or existing reservoir upstream is a significant advantage in choosing sites for run-of-the-river. A tidal power station makes use of
3185-452: Is not generally used to produce base power except for vacating the flood pool or meeting downstream needs. Instead, it can serve as backup for non-hydro generators. The major advantage of conventional hydroelectric dams with reservoirs is their ability to store water at low cost for dispatch later as high value clean electricity. In 2021, the IEA estimated that the "reservoirs of all existing conventional hydropower plants combined can store

Hydroelectricity would eventually supply some countries, including Norway , Democratic Republic of the Congo , Paraguay and Brazil , with over 85% of their electricity. In 2021 the International Energy Agency (IEA) said that more efforts are needed to help limit climate change . Some countries have highly developed their hydropower potential and have very little room for growth: Switzerland produces 88% of its potential and Mexico 80%. In 2022,
6734-594: The leading academic institutions nearby. The local industry includes commercial or academic activity in pre-clinical research and development, clinical research and development, pilot-scale manufacturing, full-scale active pharmaceutical ingredient/intermediate manufacturing, formulation, packaging, and distribution. Having no large population centres, the county's mainstream media outlets are served from nearby Tyne and Wear , including radio stations and television channels (such as BBC Look North , BBC Radio Newcastle , ITV Tyne Tees and Hits Radio North East ), along with
6825-447: The majority of daily newspapers covering the area ( The Journal , Evening Chronicle ). It is worth remembering however that although Northumberland, like many administrative areas in England, has been shorn of its geographical regional centre, that centre—Newcastle upon Tyne—remains an essential element within the entity we know as Northumberland. Newcastle's newspapers are as widely read in its Northumbrian hinterland as any of those of
6916-521: The northwest of the county, consist mainly of resistant Devonian granite and andesite lava . A second area of igneous rock underlies the Whin Sill (on which Hadrian's Wall runs), an intrusion of Carboniferous dolerite . Both ridges support a rather bare moorland landscape. Either side of the Whin Sill the county lies on Carboniferous Limestone , giving some areas of karst landscape . Lying off
7007-633: The plant site. Generation of hydroelectric power changes the downstream river environment. Water exiting a turbine usually contains very little suspended sediment, which can lead to scouring of river beds and loss of riverbanks. The turbines also will kill large portions of the fauna passing through, for instance 70% of the eel passing a turbine will perish immediately. Since turbine gates are often opened intermittently, rapid or even daily fluctuations in river flow are observed. Drought and seasonal changes in rainfall can severely limit hydropower. Water may also be lost by evaporation. When water flows it has
7098-450: The rainfall regime, could reduce total energy production by 7% annually by the end of the century. Lower positive impacts are found in the tropical regions. In lowland rainforest areas, where inundation of a part of the forest is necessary, it has been noted that the reservoirs of power plants produce substantial amounts of methane . This is due to plant material in flooded areas decaying in an anaerobic environment and forming methane,
7189-546: The region. Tourism is a major source of employment and income in Northumberland. In the early 2000s the county annually received 1.1 million British visitors and 50,000 foreign tourists, who spent a total of £162 million. Coal mining in the county goes back to Tudor times . Coal mines continue to operate today; many of them are open-cast mines. Planning approval was given in January 2014 for an open-cast mine at Halton Lea Gate near Lambley . A major employer in Northumberland
7280-571: The source of the River North Tyne and much of the South Tyne; near Hexham they combine to form the Tyne, which exits into Tyne and Wear shortly downstream. The other major rivers in Northumberland are, from south to north, the Blyth , Coquet , Aln , Wansbeck and Tweed , the last of which forms part of the Scottish border. The county contains Northumberland National Park and two national landscapes :
7371-669: The success and history of their respective clubs. They both became permanent fixtures in Alf Ramsey's 1966 England World Cup winning team. Malcolm Macdonald was a successful Newcastle player of the 1970s. Great national players who played at Northumberland clubs in the 1980s and 1990s include Peter Beardsley , Paul Gascoigne , Chris Waddle and Alan Shearer . Shearer remains the highest scoring player in Premier League history with 260 goals in 441 appearances. Early races were held at Newcastle's Killingworth Moor from 1632 before moving to
7462-507: The west. About a quarter of the county forms the Northumberland National Park , an area of outstanding landscape that has largely been protected from development and agriculture. The park stretches south from the Scottish border and includes Hadrian's Wall . Most of the park is over 240 metres (790 feet) above sea level. The Northumberland Coast is also a designated Area of Outstanding Natural Beauty (AONB). A small part of
7553-926: The wider county: the Northumberland Gazette , Morpeth Herald , Berwick Advertiser , Hexham Courant and the News Post Leader . Lionheart Radio , a community radio station based in Alnwick , has recently been awarded a five-year community broadcasting licence by Ofcom . Ashington has the former Alcan Lynemouth Aluminium Smelter , next to the Lynemouth Power Station . Hammerite and Cuprinol are made in Prudhoe by ICI Paints . A Procter & Gamble factory in Seaton Delaval makes Hugo Boss aftershave and Clairol and Nice 'n Easy hair dye at
7644-524: The world are hydroelectric power stations, with some hydroelectric facilities capable of generating more than double the installed capacities of the current largest nuclear power stations . Although no official definition exists for the capacity range of large hydroelectric power stations, facilities from over a few hundred megawatts are generally considered large hydroelectric facilities. Currently, only seven facilities over 10 GW ( 10,000 MW ) are in operation worldwide, see table below. Small hydro
7735-539: The world. The classification of hydropower plants starts with two top-level categories: The classification of a plant as an SHP or LHP is primarily based on its nameplate capacity , the threshold varies by the country, but in any case a plant with the capacity of 50 MW or more is considered an LHP. As an example, for China, SHP power is below 25 MW, for India - below 15 MW, most of Europe - below 10 MW. The SHP and LHP categories are further subdivided into many subcategories that are not mutually exclusive. For example,
7826-421: Was Hexham . At the 2001 UK Census Northumberland registered a population of 307,190, estimated to be 309,237 in 2003, The 2011 UK Census gave a population of 316,028. In 2001 there were 130,780 households, 10% of the population were retired, and one-third rented their homes. Northumberland has an ethnic minority population at 0.985% of the population, far lower compared to the average of 9.1% for England as
7917-573: Was allowed to provide irrigation and power to citizens (in addition to aluminium power) after the war. In Suriname , the Brokopondo Reservoir was constructed to provide electricity for the Alcoa aluminium industry. New Zealand 's Manapouri Power Station was constructed to supply electricity to the aluminium smelter at Tiwai Point . Since hydroelectric dams do not use fuel, power generation does not produce carbon dioxide . While carbon dioxide
8008-503: Was first drawn up in the 1950s. The historic county town was Alnwick ; assizes were mainly held in Newcastle , with the county gaol in Morpeth . Newcastle became a city in 1400, with county corporate status, with both areas having joint assizes. From the county council 's formation in 1889 until 1981 Newcastle was the county town , being briefly the county town of two counties when
8099-482: Was killed playing football when David Le Keu's knife went into Henry's belly and killed him. Organised football teams as we know today did not appear until the 1870s. Newcastle United Football Club was formed in 1892 by uniting Newcastle West End FC with Newcastle East End. Newcastle United were first division champions three times in the early 20th century, reaching the FA Cup Final three times before winning it at
8190-581: Was produced as a blank page. Notable players after the Second World War included Joe Harvey , Jackie Milburn , Brian Clough and Newcastle's Bobby Moncur who led his team to win the Inter City Fairs Cup in 1969. Two of Jackie Milburn's nephews from Ashington , Bobby Charlton and Jackie Charlton are perhaps the two most significant players for England . Bobby joined Manchester United and Jackie Leeds United both contributing much to
8281-617: Was united with Deira (south of the River Tees ) to form the kingdom of Northumbria in the 7th century. The boundaries of Northumbria under King Edwin (reigned 616–633) stretched from the Humber in the south to the Forth in the north. Northumberland is often called the "cradle of Christianity" in England because Christianity flourished on Lindisfarne —a tidal island north of Bamburgh , also called Holy Island—after King Oswald of Northumbria (r. 634–642) invited monks from Iona to come to convert
