Energy In Bulgaria
About 200 TWh of energy in Bulgaria is consumed each year which is about 28 MWh per person, somewhat over the world average of 20 MWh. The largest sources are coal and oil, followed by nuclear. Bulgaria does not produce much coal, oil and gas. Nuclear power produces 36% of Bulgaria's power, with the remaining 64% produced from fossil fuels, and without a domestic supply, the country is heavily dependent on imports for crude oil. Economics To improve the corporate management and supervision of the energy sector, on 13 February 2008 the Government of Bulgaria decided to set up a state-owned energy holding company Bulgarian Energy Holding, a successor of the state-owned 'Neft i Gas' (Oil and Gas) established in 1973. The holding company's business composes of subsidiaries operating in different energy sectors: electricity: Kozloduy nuclear power plant, Maritsa East 2 thermal power plant, NEK EAD and Elektroenergien sistemen operator (ESO); natural gas: Bulgargaz and Bulgartransgaz ...

Hydraulic Fracturing
Fracking (also known as hydraulic fracturing, hydrofracturing, or hydrofracking) is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open. Hydraulic fracturing began as an experiment in 1947, and the first commercially successful application followed in 1950. As of 2012, 2.5 million "frac jobs" had been performed worldwide on oil and gas wells, over one million of those within the U.S. Such treatment is generally necessary to achieve adequate flow rates in shale gas, tight gas, tig ...

Fossil Fuel Subsidies
Fossil fuel subsidies are energy subsidies on fossil fuels. They may be tax breaks on consumption, such as a lower sales tax on natural gas for residential heating; or subsidies on production, such as tax breaks on exploration for oil. Or they may be free or cheap negative externalities; such as air pollution or climate change due to burning gasoline, diesel and jet fuel. Some fossil fuel subsidies are via electricity generation, such as subsidies for coal-fired power stations. One downside to subsidizing any industry is that competition and innovation are lessened or lost completely. Subsidizing can make a product be cheaper for buyers, but in the long run, innovation and lower prices come from a competitive free market. Despite the G20 countries having pledged to phase-out inefficient fossil fuel subsidies, they may be continued because of voter demand or for energy security. Global fossil fuel consumption subsidies in 2021 have been estimated at 440 billion dollars; a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VVER
The water-water energetic reactor (WWER), or VVER (from russian: водо-водяной энергетический реактор; transliterates as ; ''water-water power reactor'') is a series of pressurized water reactor designs originally developed in the Soviet Union, and now Russia, by OKB Gidropress. The idea of such a reactor was proposed at the Kurchatov Institute by Savely Moiseevich Feinberg. VVER were originally developed before the 1970s, and have been continually updated. As a result, the name VVER is associated with a wide variety of reactor designs spanning from generation I reactors to modern generation III+ reactor designs. Power output ranges from 70 to 1300 MWe, with designs of up to 1700 MWe in development. The first prototype VVER-210 was built at the Novovoronezh Nuclear Power Plant. VVER power stations have mostly been installed in Russia and the former Soviet Union, but also in China, the Czech Republic, Finland, Germany, Hungary, Slovakia, Bulgaria, Indi ...

Pressurized Water Reactor
A pressurized water reactor (PWR) is a type of light-water reactor, light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan and Canada). In a PWR, the primary nuclear reactor coolant, coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the Nuclear fission, fission of atoms. The heated, high pressure water then flows to a Water-tube boiler, steam generator, where it transfers its thermal energy to lower pressure water of a secondary system where steam is generated. The steam then drives turbines, which spin an electric generator. In contrast to a boiling water reactor (BWR), pressure in the primary coolant loop prevents the water from boiling within the reactor. All light-water reactors use ordinary water as both coolant and neutron moderator. Most use anywhere from two to four vertically mounted steam generators; VVER reactors use horizo ...

Liquefied Natural Gas
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure). LNG is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately ; maximum transport pressure is set at around (gauge pressure), which is about one-fourth times atmospheric pressure at sea level. The gas extracted from underground hydrocarbon deposits contains a varying mix of hy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deputy Prime Minister
A deputy prime minister or vice prime minister is, in some countries, a government minister who can take the position of acting prime minister when the prime minister is temporarily absent. The position is often likened to that of a vice president, as both positions are "number two" offices, but there are some differences. The states of Australia and provinces of Canada each have the analogous office of deputy premier. In the devolved administrations of the United Kingdom, an analogous position is that of the deputy First Minister, albeit the position in Northern Ireland has equivalent powers to the First Minister differing only in the titles of the offices. In Canada, the position of deputy prime minister should not be confused with the Canadian deputy minister of the prime minister of Canada, a nonpolitical civil servant position. In Austria and Germany, the officeholder is known as vice-chancellor. A deputy prime minister traditionally serves as acting prime minister when the ...

2022 Russian Invasion Of Ukraine
On 24 February 2022, in a major escalation of the Russo-Ukrainian War, which began in 2014. The invasion has resulted in tens of thousands of deaths on both sides. It has caused Europe's largest refugee crisis since World War II. An estimated 8 million Ukrainians were displaced within their country by late May and 7.8 million fled the country by 8 November 2022, while Russia, within five weeks of the invasion, experienced its greatest emigration since the 1917 October Revolution. Following the 2014 Ukrainian Revolution, Russia annexed Crimea, and Russian-backed paramilitaries seized part of the Donbas region of south-eastern Ukraine, which consists of Luhansk and Donetsk oblasts, sparking a regional war. In March 2021, Russia began a large military build-up along its border with Ukraine, eventually amassing up to 190,000 troops and their equipment. Despite the build-up, denials of plans to invade or attack Ukraine were issued by various Russian gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reuters
Reuters ( ) is a news agency owned by Thomson Reuters Corporation. It employs around 2,500 journalists and 600 photojournalists in about 200 locations worldwide. Reuters is one of the largest news agencies in the world. The agency was established in London in 1851 by the German-born Paul Reuter. It was acquired by the Thomson Corporation of Canada in 2008 and now makes up the media division of Thomson Reuters. History 19th century Paul Reuter worked at a book-publishing firm in Berlin and was involved in distributing radical pamphlets at the beginning of the Revolutions in 1848. These publications brought much attention to Reuter, who in 1850 developed a prototype news service in Aachen using homing pigeons and electric telegraphy from 1851 on, in order to transmit messages between Brussels and Aachen, in what today is Aachen's Reuters House. Reuter moved to London in 1851 and established a news wire agency at the London Royal Exchange. Headquartered in London, Reuter' ...

Turk Stream
TurkStream ( tr, TürkAkım or ''Türk Akımı'', russian: Турецкий поток; former name: Turkish Stream) is a natural gas pipeline running from Russia to Turkey. It starts from Russkaya compressor station near Anapa in Russia's Krasnodar Region, crossing the Black Sea to the receiving terminal at Kıyıköy. Some gas flows onwards to the European Union. History The first direct gas pipeline between Russia and Turkey under the Black Sea was Blue Stream, which was commissioned in 2005. In 2009, Russia′s prime minister Vladimir Putin proposed the Blue Stream II line parallel to the original pipeline. The Blue Stream II project never took off and the South Stream project took the lead, until it was abandoned in 2014. The TurkStream (then named Turkish Stream) project was announced by Russia′s president Vladimir Putin on 1 December 2014 during his state visit to Turkey, when a memorandum of understanding was signed between Gazprom and BOTAŞ.
