Electricity Sector In Iceland
The electricity sector in Iceland is 99.98% reliant on renewable energy: hydro power, geothermal energy and wind energy. Iceland's consumption of electricity per capita was seven times higher than EU 15 average in 2008. The majority of the electricity is sold to industrial users, mainly aluminium smelters and producers of ferroalloy. The aluminum industry in Iceland used 71% of produced electricity in 2011. Landsvirkjun is the country's largest electricity producer. The largest companies in the retail market are RARIK, Orkuveita Reykjavíkur and Hitaveita Suðurnesja. Electricity production increased significantly between 2005 and 2008 with the completion of Iceland's largest hydroelectric dam, Kárahnjúkar Hydropower Plant (690MW).Energy in Sweden, Facts and figures Energiläget i siffror ,The Swedish Energy Agency, Specific electricity production per inhabitant with breakdown by power source, (kWh/person) Source: IEA/OEC2006 T23 2007 T25 2008 T262009 T25 an2010 T49 Iceland's ...

Wind Power
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. Onshore wind farms have a greater visual #Impact on environment and landscape, impact on the landscape than some other power stations.

HVDC Europe Annotated
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages between 100 kV and 800 kV. However, a 1,100 kV link in China was completed in 2019 over a distance of with a power capacity of 12 GW. With this dimension, intercontinental connections become possible which could help to deal with the fluctuations of wind power and photovoltaics. HVDC allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows the transfer of power between grid systems running at different frequencies, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Substation
A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. They are a common component of the infrastructure, for instance there are 55,000 substations in the United States. Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control. The word ''substation'' comes from the days before the distribution system became a grid. As central generation stations became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the same rela ...

Diesel Generator
A diesel generator (DG) (also known as a diesel Genset) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. This is a specific case of engine generator. A diesel compression-ignition engine is usually designed to run on diesel fuel, but some types are adapted for other liquid fuels or natural gas. Diesel generating sets are used in places without connection to a power grid, or as an emergency power supply if the grid fails, as well as for more complex applications such as peak-lopping, grid support, and export to the power grid. Diesel generator size is crucial to minimize low load or power shortages. Sizing is complicated by the characteristics of modern electronics, specifically non-linear loads. In size ranges around 50 MW and above, an open cycle gas turbine is more efficient at full load than an array of diesel engines, and far more compact, with comparable capital costs; but for regular part-loading, ...

Iceland Electricity Production
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first permane ...

Flatey, Breiðafjörður
Flatey () is an island of the western islands, a cluster of about forty large and small islands and islets located in Breiðafjörður on the northwestern part of Iceland. Flatey and its surrounding islands are, as a creation, believed to have forged from under the weight of a great glacier during the previous Ice age. In terms of size, Flatey is some two kilometers long and about one kilometer wide, of which most is flat land (hence its name, meaning "flat island" in Icelandic), with scarcely any hills to be found. The island has a seasonal habitation; most houses there are occupied only during summer. In winter, the island's total population is five people. In spite of this, Flatey used to be one of the main cultural centres of Iceland, with its no-longer existing monastery (founded in 1172) standing on the highest point of the island as its beacon of knowledge. In the middle of the 19th century, Flatey was still a cultural and artistic centre but doubled as a hub of commerc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grímsey
Grímsey () is a small Icelandic island, off the north coast of the main island of Iceland, straddling the Arctic Circle. In January 2018 Grímsey had 61 inhabitants. Before 2009, Grimsey constituted the ''hreppur'' (municipality) of Grímseyjarhreppur . In that year, island residents voted to join the municipality with Akureyri. The island's only settlement is Sandvík. Geography Grímsey is the northernmost inhabited Icelandic territory; the rapidly disappearing islet of Kolbeinsey lies some farther north, but is uninhabitable. The closest land is the island of Flatey, Skjálfandi, to the south. The Arctic Circle currently runs through the island, a feature of interest to many visitors, while the entirety of mainland Iceland lies south of the Arctic Circle. Due to long-term oscillations in the Earth's axis, the Arctic Circle currently Circle of latitude#Movement of the Tropical and Polar circles, shifts northward by about per year, though varying substantially from ...
