Possum Point
Possum Point is a small peninsula in Northern Virginia that juts out into Quantico Creek and separates it from the Potomac River. It lies in a suburban area of Washington D.C. Dominion Virginia Power operates a power plant on the point. The area is rich in Civil War History, and a nearby peak, Possum Nose, was the site of a Confederate fort. Possum Point Power Station Possum Point Power Station is a power plant owned by Dominion Virginia Power (A division of Dominion Resources). The plant supplies some of the electricity for the Northern Virginia suburbs of Washington D.C. It burns natural gas and oil, however it used to burn coal, and was converted in 2003. Unit 6, a combined cycle unit, was also installed in 2003. Unit 5 was scheduled for retirement by June 1, 2021. Units 3 & 4, previously converted from coal to natural gas, have been identified for retirement in a move away from steam generation. Generating Units {, class="wikitable" , - ! Unit Number ! Fuel !

Peninsula
A peninsula (; ) is a landform that extends from a mainland and is surrounded by water on most, but not all of its borders. A peninsula is also sometimes defined as a piece of land bordered by water on three of its sides. Peninsulas exist on all continents. The size of a peninsula can range from tiny to very large. The largest peninsula in the world is the Arabian Peninsula. Peninsulas form due to a variety of causes. Etymology Peninsula derives , which is translated as 'peninsula'. itself was derived , or together, 'almost an island'. The word entered English in the 16th century. Definitions A peninsula is usually defined as a piece of land surrounded on most, but not all sides, but is sometimes instead defined as a piece of land bordered by water on three of its sides. A peninsula may be bordered by more than one body of water, and the body of water does not have to be an ocean or a sea. A piece of land on a very tight river bend or one between two rivers is sometimes s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantico Creek
Quantico Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 partially tidal tributary of the Potomac River in eastern Prince William County, Virginia. Quantico Creek rises southeast of Independent Hill, flows through Prince William Forest Park and Dumfries and empties into the Potomac at Possum Point. History John Smith in 1608 reported the existence of a Doeg community called ''Pamacocack'' on the banks of this creek, as well as on the directly opposite (Maryland) side of the Potomac. This is thought to be a likely candidate for the place Henry Spelman was found living among the natives, which he reported was named "Nacottawtanke, but by our english cald icCamocacocke". Early land patents spell the name of the creek variously as ''Quancico'' (1654), ''Quanticotte'' (1654, 1658), ''Quantecot'' (1657), ''Quanticoke'' (1664), ''Quonticutt'' (1665), and ''Quanticutt'' (1665).Nugent, ''Cavalier ...

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Confederate States Of America
The Confederate States of America (CSA), commonly referred to as the Confederate States or the Confederacy was an unrecognized breakaway republic in the Southern United States that existed from February 8, 1861, to May 9, 1865. The Confederacy comprised U.S. states that declared secession and warred against the United States during the American Civil War: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee, and North Carolina. Kentucky and Missouri also declared secession and had full representation in the Confederate Congress, though their territory was largely controlled by Union forces. The Confederacy was formed on February 8, 1861, by seven slave states: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas. All seven were in the Deep South region of the United States, whose economy was heavily dependent upon agriculture—particularly cotton—and a plantation system that relied upon enslaved ...

Combined Cycle
A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant. The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant. Combining two or more thermodynamic cycles improves overall efficiency, which reduces fuel costs. The principle is that after completing its cycle in the first engine, the working fluid (the exhaust) is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. Usually the heat passes through a heat exchanger so that the two engines can use different working fluids. By generating power from multiple streams of work, the overall efficiency can be increased by 50–60%. That is, from an overall efficiency of the system of say 34% for a simple cycle, to as much as 64% ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Gas
Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Natural gas is colorless and odorless, so odorizers such as mercaptan (which smells like sulfur or rotten eggs) are commonly added to natural gas supplies for safety so that leaks can be readily detected. Natural gas is a fossil fuel and non-renewable resource that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...
