Electricity Sector In Armenia
The electricity sector of Armenia includes several companies engaged in electricity generation and distribution. Generation is carried out by multiple companies both state-owned and private. As of 2016, the majority of the electricity sector is privatized and foreign-owned (by Russian and American companies), which is the result of a law passed in 1998 allowing for the privatization of electricity generation and distribution in the country. Administration, government legislation, and policy of the sector is conducted by the Ministry of Energy Infrastructures and Natural Resources (Armenia), Ministry of Energy Infrastructures and Natural Resources of Armenia. Regulation of the sector is performed by the Public Services Regulatory Commission of Armenia. Armenia does not have any fossil-fuel reserves, so it relies on gas imports from Russia and Iran, and nuclear fuel imports from Russia, which, together, result in approximately 66% of electricity production. Armenia is a net-produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt
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 after 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. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre 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). : ...

Walkabout Travel Gear
Walkabout Travel Gear was an online retailer of travel accessories that was, at the time, one of few companies to begin selling on the Internet. The company went online in November 1995. The first capture by archive.org was on December 23, 1996. The domain name "walkabouttravelgear.com" was not secured until early 1996. The internet address upon startup was xmission.com/~walkgear/walk.htm. A printout of the website dated June 29, 1996, is available. Founding Walkabout Travel Gear was founded by Gia and Bradford Grant Boyle. Their original inspiration came on March 3, 1995, on the island of Malta. While on a European backpacking trip, the couple noticed there was a lack of travel gear companies targeting independent travellers on a budget. They cut their journey short, returning home to Salt Lake City, Utah. They used their remaining savings to research, purchase inventory, and produce a print catalog. The catalog was designed to capture the practicality as well as the cost consci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Power Station
A thermal power station is a type of power station in which heat energy is converted to electrical energy. In a steam-generating cycle heat is used to boil water in a large pressure vessel to produce high-pressure steam, which drives a steam turbine connected to an electrical generator. The low-pressure exhaust from the turbine enters a steam condenser where it is cooled to produce hot condensate which is recycled to the heating process to generate more high pressure steam. This is known as a Rankine cycle. The design of thermal power stations depends on the intended energy source: fossil fuel, nuclear and geothermal power, solar energy, biofuels, and waste incineration are all used. Certain thermal power stations are also designed to produce heat for industrial purposes; for district heating; or desalination of water, in addition to generating electrical power. Fuels such as natural gas or oil can also be burnt directly in gas turbines (internal combustion). These pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydro Power Plant
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.

Armenian Nuclear Power Plant
The Armenian Nuclear Power Plant (ANPP) (), also known as the Metsamor Nuclear Power Plant, (Armenian: Մեծամորի ատոմային էլեկտրակայան) is the only nuclear power plant in the South Caucasus, located 36 kilometers west of Yerevan in Armenia. The ANPP complex consists of two VVER-440 Model V270 nuclear reactors, each capable of generating 407.5 megawatts (MW) of power, for a total of 815 MW. The plant supplied approximately 40 percent of Armenia's electricity in 2015. As with other early VVER-440 plants, and unlike Western pressurized water reactors (PWR), the ANPP lacks a secondary containment building. History The ANPP complex consists of two units. The first unit was activated on 22 December 1976, and the second on 5 January 1980. Following public pressure after the Spitak Earthquake in 1988, the Council of Ministers of the Soviet Union decided to shut down the existing two units. After the fall of the USSR, Armenia had a period of energy s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wind Energy
Wind power or wind energy is mostly the use of wind turbines to electricity generation, generate electricity. Wind power is a popular, sustainable energy, sustainable, renewable energy source that has a much smaller Environmental impact of wind power, impact on the environment than burning fossil fuels. Historically, wind power has been used in sails, windmills and windpumps but today it is mostly used to generate electricity. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission Electrical grid, network. New Onshore wind farm, onshore (on-land) wind farms are cheaper than new Coal-fired power station, coal or Gas-fired power plant, gas plants, but expansion of wind power is being hindered by fossil fuel subsidies.

Solar Energy
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air. The large magnitude of solar energy available makes it a highly appealing source of electricity. In 2020 solar energy has been the cheapest source of Electricity.

Hydro Power
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. International institutions such as the World Bank view hydropower as a low-carbon means for economic development. Since ancient times, ...
