Rhea County, Tennessee
Rhea County (pronounced ) is a county located in the U.S. state of Tennessee. As of the 2020 census, the population was 32,870. Its county seat is Dayton. Rhea County comprises the Dayton, TN Micropolitan Statistical Area, which is also included in the Chattanooga-Cleveland-Dalton, TN- GA- AL Combined Statistical Area. History Rhea County is named for the Tennessee politician and Revolutionary War veteran John Rhea. A portion of the Trail of Tears ran through the county as part of the United States government's removal of the Cherokee in the 1830s. During the American Civil War, Rhea County was one of the few counties in East Tennessee that was heavily sympathetic to the cause of the Confederate States of America. It was the only East Tennessee county that did not send a delegate to the pro-Union East Tennessee Convention in 1861. The county voted in favor of Tennessee's June 1861 Ordinance of Secession, 360 votes to 202. Rhea raised seven companies for the Confederate Ar ...

Tennessee Valley Authority
The Tennessee Valley Authority (TVA) is a federally owned electric utility corporation in the United States. TVA's service area covers all of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small areas of Georgia, North Carolina, and Virginia. While owned by the federal government, TVA receives no taxpayer funding and operates similarly to a private for-profit company. It is headquartered in Knoxville, Tennessee, and is the sixth largest power supplier and largest public utility in the country. The TVA was created by Congress in 1933 as part of President Franklin D. Roosevelt's New Deal. Its initial purpose was to provide navigation, flood control, electricity generation, fertilizer manufacturing, regional planning, and economic development to the Tennessee Valley, a region that had suffered from lack of infrastructure and poverty during the Great Depression, relative to the rest of the nation. TVA was envisioned both as a power supplier and a regional economi ... [...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] |
Tennessee River
The Tennessee River is the largest tributary of the Ohio River. It is approximately long and is located in the southeastern United States in the Tennessee Valley. The river was once popularly known as the Cherokee River, among other names, as the Cherokee people had their homelands along its banks, especially in what are now East Tennessee and northern Alabama. Additionally, its tributary, the Little Tennessee River, flows into it from Western North Carolina and northeastern Georgia, where the river also was bordered by numerous Cherokee towns. Its current name is derived from the Cherokee town, ''Tanasi'', which was located on the Tennessee side of the Appalachian Mountains. Course The Tennessee River is formed at the confluence of the Holston and French Broad rivers in present-day Knoxville, Tennessee. From Knoxville, it flows southwest through East Tennessee into Chattanooga before crossing into Alabama. It travels through the Huntsville and Decatur area before rea ...

Fossil Fuel Power Station
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat. Fossil fuel power stations provide most of the electrical energy used in the world. Some fossil-fired power stations are designed for continuous operation as baseload power plants, while others are used as peaker plants. However, starting from the 2010s, in many countries plants designed for baseload supply ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Watts Bar Dam
Watts Bar Dam is a hydroelectric dam on the Tennessee River in Meigs and Rhea counties in Tennessee, United States. The dam is one of nine dams on the main Tennessee River channel operated by the Tennessee Valley Authority, which built the dam in the early 1940s to provide flood control and electricity and to help create a continuous navigable channel along the entire length of the river. The dam is the technical boundary between the Watts Bar Lake— which it impounds— and Chickamauga Lake, which stretches from the dam's tailwaters southward to Chattanooga. Watts Bar Dam is named for Watt Island, a sandbar located at the dam site prior to the dam's construction.Tennessee Valley Authority, ''The Watts Bar Project: A Comprehensive Report on the Planning, Design, Construction, and Initial Operations of the Watts Bar Project'', Technical Report No. 9 (Washington, D.C.: U.S. Government Printing Office, 1949), 1-11, 39-47.

List Of Power Stations In Tennessee
The U.S. state of Tennessee receives its power from a variety of sources. The Tennessee Valley Authority (TVA) is the primary utility in Tennessee which generates electricity and sells it to hundreds of local utilities and industrial customers. Like most of the US, the sources used to generate power in Tennessee have changed substantially in the last decade. Coal's share of power has declined from nearly 60% in 2008 to about 25% in 2018, while natural gas has increased significantly. Tennessee is home to the two newest nuclear reactors in the US at Watts Bar Nuclear Plant, unit 2 being the first to begin operation in the 21st century. After Watts Bar Unit 2 began operation in late 2016, nuclear power passed coal as the top source of electricity. In November 2018 natural gas produced more power than coal for the first time in Tennessee. Tennessee is home to the third largest pumped-storage hydroelectric facility in the US, and has the third highest net generation of hydroelectric pow ...

Energy Infrastructure Completed In 1942
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...
