166-675: Peabody Energy is a coal mining company headquartered in St. Louis , Missouri . Its primary business consists of the mining, sale, and distribution of coal, which is purchased for use in electricity generation and steelmaking. Peabody also markets, brokers, and trades coal through offices in China , Australia , and the United States . In 2022, Peabody recorded sales of 124 million tons of coal. Peabody markets coal to electricity generating and industrial customers in more than 26 nations. As of December 31, 2022,

332-530: A library service was instituted for this area. The professional staff at headquarters were generally composed of experts from outside the region. By 1934, TVA employed more than 9,000 people. The workers were classified by the usual racial and gender lines of the region, which limited opportunities for minorities and women. TVA hired a few African Americans , generally restricted for janitorial or other low-level positions. TVA recognized labor unions ; its skilled and semi-skilled blue collar employees were unionized,

498-415: A " pit head ". In Australia , "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging, and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines , trucks, conveyors , hydraulic jacks , and shearers. The coal mining industry has

664-499: A "hidden loss" by preventing the creation of "factories and jobs that would have come into existence if the government had allowed the taxpayers to spend their money as they wished". Defenders note that TVA remains overwhelmingly popular in Tennessee among conservatives and liberals alike. Business historian Thomas McCraw concludes that Roosevelt "rescued the [power] industry from its own abuses" but "he might have done this much with

830-697: A 70% increase over the 20 years since 1999. In 2018, the world production of brown coal (lignite) was 803.2 Mt, with Germany the world's largest producer at 166.3 Mt. China is most likely the second largest producer and consumer of lignite globally although specific lignite production data is not made available. Coal production has grown fastest in Asia, while Europe has declined. Since 2011, world coal production has been stable, with decreases in Europe and US offset by increases from China, Indonesia and Australia. The top coal mining nations are: Energy production from coal mining

996-405: A breakthrough in an area known for corporations hostile to miners' and textile workers' unions. Women were excluded from construction work. Many local landowners were suspicious of government agencies, but TVA successfully introduced new agricultural methods into traditional farming communities by blending in and finding local champions. Tennessee farmers often rejected advice from TVA officials, so

1162-467: A coal seam occurring near the top of a ridge or hill, the entire top is removed in a series of parallel cuts. Overburden is deposited in nearby valleys and hollows. This method usually leaves the ridge and hilltops as flattened plateaus. The process is highly controversial for the drastic changes in topography, the practice of creating head-of-hollow-fills , or filling in valleys with mining debris, and for covering streams and disrupting ecosystems. Spoil

1328-721: A consortium of companies controlled Peabody-Holding. Because of a federal contract with the Tennessee Valley Authority , the company was among 153 named in 1978 discrimination complaint with the Department of Labor Office of Federal Contract Compliance Program. The complaint, filed by the Coal Employment Project , a women’s advocacy organization, was based upon Executive Order 11246 signed in 1965 by U.S. President Lyndon Johnson , which bars sex discrimination by companies with federal contracts. The complaint called for

1494-589: A consortium of municipal electric cooperatives began construction on the 1600-megawatt Prairie State Energy Campus clean coal project in Lively Grove, Illinois . The company retained a five percent equity stake in the project, which was expected to begin generating power for customers in 2011. Peabody sold its stake in the Prairie State project to the Wabash Valley Power Association in 2016. At

1660-547: A diverse portfolio that includes nuclear , coal-fired , natural gas -fired, hydroelectric , and renewable generation. TVA sells its power to 153 local power utilities, 58 direct-serve industrial and institutional customers, 7 federal installations, and 12 area utilities. In addition to power generation, TVA provides flood control with its 29 hydroelectric dams. Resulting lakes and other areas also allow for recreational activities. The TVA also provides navigation and land management along rivers within its region of operation, which

1826-405: A fourth of the world's energy. Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called an open cast) mine. Additionally, coal seam thickness and geology are factors in the selection of a mining method. The most economical method of coal extraction for surface mines is the electric shovel or drag line. The most economical form of underground mining

1992-618: A great deal less agitation and ill will". New Dealers hoped to build numerous other federal utility corporations around the country but were defeated by lobbyist and 1940 Republican presidential nominee Wendell Willkie and the conservative coalition in Congress. The valley authority model did not replace the limited-purpose water programs of the Bureau of Reclamation and the Army Corps of Engineers . However, it has been shown that in river policy,

2158-403: A greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which operate by removing the overburden, power shovels, large trucks in which transport overburden and coal, bucket wheel excavators, and conveyors. In this mining method, explosives are first used in order to break through

2324-449: A judge ruled that Peabody Energy's bankruptcy protected it from "global-warming lawsuits brought by California coastal communities [in July 2017] against fossil-fuel companies." In 2018, Peabody announced it plans to invest $ 10 million in a partnership with London-based Arq, a company that is advancing technology to convert coal into oil products. On December 3 Peabody completed its purchase of

2490-440: A land use condition is not equal to the original use. Existing land uses (such as livestock grazing, crop and timber production) are temporarily eliminated in mining areas. High-value, intensive-land-use areas like urban and transportation systems are not usually affected by mining operations. If mineral values are sufficient, these improvements may be removed to an adjacent area. Strip mining eliminates existing vegetation, destroys

2656-440: A large dining-room table, but with hydraulic jacks for legs. After the large pillars of coal have been mined away, the mobile roof support's legs shorten and it is withdrawn to a safe area. The mine roof typically collapses once the mobile roof supports leave an area. There are six principal methods of underground mining: Coal is mined commercially in over 50 countries. 7,921 million metric tons (Mt) of coal were produced in 2019,

2822-559: A long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to the global environmental crises, such as poor air quality and climate change . For these reasons, coal has been one of the first fossil fuels to be phased out of various parts of the global energy economy . The major coal producing countries, though, such as China , Indonesia, India and Australia , have not reached peak production, with production increases replacing falls in Europe and

2988-447: A method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof. Once room and pillar mines have been developed to a stopping point limited by geology, ventilation, or economics, a supplementary version of room and pillar mining, termed second mining or retreat mining ,

3154-440: A new coal mine. 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

3320-466: A number of coal-to-liquids and coal-to-gas projects to reduce emissions during the decade. On August 30, 2007, Ernie Fletcher , the governor of the U.S. state of Kentucky signed into state law a bill that will provide approximately $ 300 million in incentives to Peabody to build a coal gasification plant in that state. The resulting incentives were provisioned in the form of breaks on sales taxes, incentive taxes and coal severance taxes. In 2007, Peabody and

3486-635: A plan to meet the energy needs of the Tennessee Valley through 2020. In 1992 work resumed on Watts Bar Unit 1 , and the reactor began operation in May 1996. This was the last commercial nuclear reactor in the United States to begin operation in the 20th century. In 2002, TVA began work to restart Browns Ferry Unit 1 , the last of TVA's reactors that had been mothballed in 1985. This unit returned to service in 2007. In 2004, TVA implemented recommendations from

3652-473: A potential future Ebola vaccine. Peabody's claim was criticized by three public health academics as "an insult", and an "opportunistic attempt and somewhat desperate to relate corporate self-interest to a massive public health crisis". In Newsweek 's 2012 Green Rankings—comparisons of the environmental footprint, management, and transparency of the largest public companies in America—Peabody Energy

3818-486: 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

3984-422: A projected future increase in electrical consumption, TVA began constructing 500 kilovolt (kV) transmission lines, the first of which was placed into service on May 15, 1965. Electric rates were among the nation's lowest during this time and stayed low as TVA brought larger, more efficient generating units into service. Plants completed during this time included Paradise , Bull Run , and Nickajack Dam . Expecting

4150-823: A projection of further rapid increase in power demand. However, in the 1980s, it became increasingly evident that the agency had vastly overestimated the Valley's future energy needs, and rapid increases in construction costs and new regulations following the Three Mile Island accident posed additional obstacles to this undertaking. In 1981, the board voted to defer the Phipps Bend plant, as well as to slow down construction on all other projects. The Hartsville and Yellow Creek plants were cancelled in 1984 and Bellefonte in 1988. Citing safety concerns, all of TVAs five operating nuclear reactors were indefinitely shut down in 1985 with

4316-564: A proposal from industrialist Henry Ford to build a private dam and create a utility to modernize the Tennessee Valley. In 1930, Norris sponsored the Muscle Shoals Bill , which would have built a federal dam in the valley, but it was vetoed by President Herbert Hoover , who believed it to be socialistic . The idea behind the Muscle Shoals project became a core part of President Franklin D. Roosevelt 's New Deal program that created

4482-574: A result of occupational exposures is coined occupational hearing loss . To protect miners' hearing, the US Mine Safety and Health Administration 's (MSHA) guidelines for noise place a Permissible Exposure Limit (PEL) for noise at 90 dBA time-weighted over 8 hours. A lower cutoff, 85 dBA, is set for a worker to fall into the MSHA Action Level which dictates that workers be placed into hearing conservation programs. Noise exposures vary depending on

4648-743: A series of lease agreements with the Navajo tribe and two years later with the Hopi tribe for mineral rights as well as the use of a water source on the Black Mesa , a 2.1-million-acre highland in Northeast Arizona. The company's contracts with the Navajo Nation and Hopi Tribe were approved despite opposition from those who disputed the authority of the official tribal councils. They were also negotiated by natural resources attorney John Sterling Boyden, who represented

4814-708: A severe decline in potable water. Peabody contends that operations consumed only one percent of the aquifer's water. Peabody developed and operated two strip mines on the Black Mesa reservation: the Black Mesa Mine and the Kayenta Mine. The Black Mesa Mine suspended operations in 2006 after the mine's sole customer, the Mohave Station, was retired. The site was fully decommissioned in January 2010. In 2015, an investigation by

4980-922: A small number of 115kV and 230kV lines in Alabama and Georgia that connect to Southern Company lines of the same voltage. TVA has conveyed approximately 485,420 acres (1,964.4 km ) of property for recreation and preservation purposes including public parks, public access areas and roadside parks, wildlife refuges, national parks and forests, and other camps and recreation areas, comprising approximately 759 different sites. Currently, TVA manages approximately 293,000 acres (1,190 km ) of Federally-owned land for public use. These lands are managed as either TVA Natural Areas or TVA Day-Use Recreation Areas. Natural Areas are smaller, ecologically or historically significant areas set aside for conservation, with some areas including hiking and walking trails. Day-Use Recreation Areas comprise approximately 80 different locations throughout

5146-725: A threat and emitting carbon dioxide is beneficial instead of being dangerous. The company also funded at least two dozen climate change denial organizations and front groups such as the George C. Marshall Institute , the Institute for Energy Research , Committee for a Constructive Tomorrow , and the Center for the Study of Carbon Dioxide and Global Change as well as scientists being famous for their contrarian opinions, among them Willie Soon , Richard Lindzen and Roy Spencer . Nick Surgey, director of research for

5312-472: A ticker symbol BTU. It also changed the company logo from Peabody Energy to just Peabody. The Peabody Energy company was founded as Peabody, Daniels & Company in 1883 by Francis Peabody , the son of a prominent Chicago lawyer, and a partner. The company bought coal from established mines and sold it to homes and businesses in the Chicago area. In the late 1880s, Francis Peabody bought out his partner's share of

5478-575: Is accomplished by drilling holes into the overburden, filling the holes with explosives, and detonating the explosive. The overburden is then removed, using large earth-moving equipment, such as draglines , shovel and trucks, excavator and trucks, or bucket-wheels and conveyors. This overburden is put into the previously mined (and now empty) strip. When all the overburden is removed, the underlying coal seam will be exposed (a 'block' of coal). This block of coal may be drilled and blasted (if hard) or otherwise loaded onto trucks or conveyors for transport to

5644-427: Is commonly started. Miners remove the coal in the pillars, thereby recovering as much coal from the coal seam as possible. A work area involved in pillar extraction is called a pillar section. Modern pillar sections use remote-controlled equipment, including large hydraulic mobile roof-supports, which can prevent cave-ins until the miners and their equipment have left a work area. The mobile roof supports are similar to

5810-418: Is dedicated to mining activities until it can be reshaped and reclaimed. If mining is allowed, resident human populations must be resettled off the mine site; economic activities, such as agriculture or hunting and gathering food and medicinal plants are interrupted. What becomes of the land surface after mining is determined by the manner in which the mining is conducted. Usually reclamation of disturbed lands to

5976-575: Is governed by a nine-member part-time board of directors, nominated by the president of the United States and confirmed by the Senate . A minimum of seven of the directors are required to be residents of TVA's service area. The members select the chair from their number, and serve five-year terms. They receive annual stipends of $ 45,000 ($ 50,000 for the chair). The board members choose the TVA's chief executive officer . When their terms expire, directors may remain on

6142-516: Is highly concentrated in certain jurisdictions, which also concentrates much of the social and economic impacts of the industry to these regions. The industry directly employs over seven million workers worldwide, which, in turn, creates millions of indirect jobs. In several parts of the world, producers have reached peak coal as some economies shift away from fossil fuels to address climate change. A 2020 study found that renewables jobs could feasibly be created in these geographies to replace many of

6308-479: Is mostly used to generate electricity, and 75% of annual coal production is exported, mostly to eastern Asia. In 2007, 428 million tonnes of coal was mined in Australia. In 2007, coal provided about 85% of Australia's electricity production. In the fiscal year 2008/09, 487 million tonnes of coal was mined, and 261 million tonnes was exported. In the fiscal year 2013/14, 430.9 million tonnes of coal

6474-417: Is partially economically recoverable. Coal refuse is distinct from the byproducts of burning coal, such as fly ash . Piles of coal refuse can have significant negative environmental consequences, including the leaching of iron, manganese, and aluminum residues into waterways and acid mine drainage . The runoff can create both surface and groundwater contamination. The piles also create a fire hazard, with

6640-593: Is placed at the head of a narrow, steep-sided valley or hollow. In preparation for filling this area, vegetation and soil are removed and a rock drain constructed down the middle of the area to be filled, where a natural drainage course previously existed. When the fill is completed, this underdrain will form a continuous water runoff system from the upper end of the valley to the lower end of the fill. Typical head-of-hollow fills are graded and terraced to create permanently stable slopes. Most coal seams are too deep underground for opencast mining and require underground mining,

6806-608: Is primarily concerned with the brokering of coal sales, trading coal, and freight or freight-related contracts. A smaller division of Peabody Energy deals with mining, export, and transportation joint ventures, energy-related commercial activities, and the management of Peabody's operations and holdings. With a growing demand for coal across Asian markets, especially in China, Indonesia, and India, Peabody has expanded its presence in Asia through offices in China, Indonesia, and Singapore. In 1964 Peabody Energy subsidiary Peabody Western Coal signed

6972-436: Is referred to as 'overburden' and is removed in long strips. The overburden from the first strip is deposited in an area outside the planned mining area and referred to as out-of-pit dumping. Overburden from subsequent strips is deposited in the void left from mining the coal and overburden from the previous strip. This is referred to as in-pit dumping. It is often necessary to fragment the overburden by use of explosives. This

7138-515: Is removed and overburden dumped to the side. Dust, vibration, and diesel exhaust odors are created (affecting sight, sound, and smell). Residents of local communities often find such impacts disturbing or unpleasant. In case of mountaintop removal , tops are removed from mountains or hills to expose thick coal seams underneath. The soil and rock removed is deposited in nearby valleys, hollows and depressions, resulting in blocked (and contaminated) waterways. Removal of soil and rock overburden covering

7304-502: Is staffed 24 hours a day to spot any threats to TVA's 16,000 miles of transmission lines. Given continued economic pressure on the coal industry, the TVA board defied President Donald Trump and voted in February 2019 to close two aging coal plants, Paradise Unit 3 and Bull Run. TVA chief executive Bill Johnson said the decision was not about coal, per se, but rather "about keeping rates as low as feasible". They stated that decommissioning

7470-653: Is still common, with 4,000 new cases of black lung every year in the US (4 percent of workers annually) and 10,000 new cases every year in China (0.2 percent of workers). The use of water sprays in mining equipment reduces the risk to miners' lungs. Build-ups of a hazardous gas are known as damps, possibly from the German word Dampf which means steam or vapor: Noise is also a contributing factor to potential adverse effects on coal miners' health. Exposure to excessive noise can lead to noise-induced hearing loss . Hearing loss developed as

7636-552: Is the fifth-largest river system in the United States, and assists governments and private companies on economic development projects. TVA's headquarters are located in Downtown Knoxville , with large administrative offices in Chattanooga (training/development; supplier relations; power generation and transmission) and Nashville (economic development) in Tennessee and Muscle Shoals, Alabama . TVA's headquarters were housed in

7802-464: Is the long wall, which involves using two spinning drums with carbide bits that runs along sections of the coal seam. Many coals extracted from both surface and underground mines require washing in a coal preparation plant . Technical and economic feasibility are evaluated based on the following: regional geological conditions; overburden characteristics; coal seam continuity, thickness, structure, quality, and depth; strength of materials above and below

7968-505: Is under the jurisdiction of the SERC Reliability Corporation . Like most North American utilities, TVA uses a maximum transmission voltage of 500 kilovolts (kV), with lines carrying this voltage using bundled conductors with three conductors per phase. The vast majority of TVA's transmission lines carry 161 kV, with the company also operating a number of sub-transmission lines with voltages of 69 kV and 46kV. They also operate

8134-649: Is used by the National Nuclear Security Administration for nuclear weapons , where it is used to supercharge and boost the explosive yield of the U.S. nuclear arsenal . TVA owns and operates its own electric grid , which consists of approximately 16,200 miles (26,100 km) of lines, one of the largest grids in the United States. This grid is part of the Eastern Interconnection of the North American power transmission grid , and

8300-435: Is used for both thermal and metallurgical coals . In New South Wales open casting for steam coal and anthracite is practiced. Surface mining accounts for around 80 percent of production in Australia, while in the US it is used for about 67 percent of production. Globally, about 40 percent of coal production involves surface mining. Strip mining exposes coal by removing earth above each coal seam. This earth to be removed

8466-527: The Environmental Protection Agency (EPA), four state governments, and three environmental groups to drastically reduce pollution and carbon emissions. Under the terms of the agreement, TVA was required to retire at least 18 of its 59 coal-fired units by the end of 2018, and install scrubbers in several others or convert them to make them cleaner, at a cost of $ 25 billion, by 2021. As a result, TVA closed several of its coal-fired power plants in

Coal remains an important energy source. Coal is also mined today on a large scale by open pit methods wherever the coal strata strike the surface or are relatively shallow. Britain developed the main techniques of underground coal mining from

8798-912: The North Antelope Rochelle Mine located in Campbell County, Wyoming , which mined more than 60 million tons of coal in 2022. Peabody spun off coal mining operations in West Virginia and Kentucky into Patriot Coal Corporation in October 2007. In October 2011, Peabody acquired a majority ownership stake in Queensland -based Macarthur Coal Ltd, which specializes in the production of metallurgical coal , primarily seaborne pulverized injection coal. The company filed for Chapter 11 bankruptcy protection on April 13, 2016. The company emerged from bankruptcy on April 3, 2017, and started trading on NYSE with

Roosevelt expressed his belief that private utilities had "selfish purposes" and said, "Never shall the federal government part with its sovereignty or with its control of its power resources while I'm President of the United States." U.S. Senator George W. Norris of Nebraska also distrusted private utility companies, and in 1920 blocked

9296-700: The Tennessee Electric Power Company (TEPCO), Jo Conn Guild , was vehemently opposed to the creation of TVA, and with the help of attorney Wendell Willkie , challenged the constitutionality of the TVA Act in federal court. The U.S. Supreme Court again upheld the TVA Act, however, in its 1939 decision Tennessee Electric Power Company v. TVA . On August 16, 1939, TEPCO was forced to sell its assets, including Hales Bar Dam , Ocoee Dams 1 and 2 , Blue Ridge Dam and Great Falls Dam to TVA for $ 78 million (equivalent to $ 1.34 billion in 2023 ).

The Natural Resources Defense Council has been critical of Peabody's advocacy for expanding coal generated electricity in the U.S., specifically on account of the environmental impacts of surface mining operations. The environmental impact of Peabody's surface mining operations in Muhlenberg County, Kentucky

10624-831: The Eastern District of Tennessee . The initial spill resulted in no injuries or deaths, but several of the employees of an engineering firm hired by TVA to clean up the spill developed illnesses, some of which were fatal, and in November 2018, a federal jury ruled that the contractor did not properly inform the workers about the dangers of exposure to coal ash and had failed to provide them with necessary personal protective equipment. In 2009, to gain more access to sustainable, green energy, TVA signed 20-year power purchase agreements with Maryland-based CVP Renewable Energy Co. and Chicago-based Invenergy Wind LLC for electricity generated by wind farms. In April 2011, TVA reached an agreement with

The following year, the company announced its intention to construct an Advanced Pressurized Water Reactor at its Bellefonte site in Alabama, filing the necessary applications in November 2007. This proposal was gradually trimmed over the following years, and essentially voided by 2016. In October 2007, construction resumed on Watts Bar Unit 2 . which began commercial operation in October 2016. Watts Bar Unit 2

11952-544: The Shoal Creek Seaborne metallurgical coal mine from private coal producer Drummond Company, Inc. for $ 387 million. In 2021, U.S. coal industry veteran Jim Grech was appointed the new president and CEO of Peabody effective June 1. Peabody Energy's world headquarters is in St. Louis , and, as of 2014, it also maintains offices in London , Beijing , Singapore , Brisbane , Sydney , Essen , Balikpapan , and Jakarta . In

12118-628: The TVA Board of Directors broke with previous tradition and took a hard line against white-collar unions during contract negotiations. As a result, a class action suit was filed in 1984 in U.S. District Court charging the agency with sex discrimination under Title VII of the Civil Rights Act of 1964 based on the large number of women in one of the pay grades negatively impacted by the new contract. TVA reached an out-of-court settlement in 1987, in which they agreed to contract modifications and paid

12284-689: The TVA Board voted to approve an advanced approach of nuclear energy technology with an estimated $ 200 million investment, known as the New Nuclear Program (NNP) in February 2022. This would promote the construction of new nuclear power facilities, particularly small modular reactors , with the first facility being constructed in partnership with Oak Ridge National Laboratory at the Clinch River Nuclear Site in Oak Ridge . On December 23, 2022, TVA had several hours of rolling blackouts due to

12450-419: The TVA chairman and another board member, saying they were overpaid and had outsourced 200 high-tech jobs. The move came after U.S. Tech Workers, a nonprofit that works to limit visas given to foreign technology workers, criticized the TVA for laying off its own workers and replacing them with contractors using foreign workers with H-1B visas . Citing its aspiration to reach net-zero carbon emissions in 2050,

12616-477: The TVA forced residents to sell their property at values less than the fair market value , and indirectly destabilized the real estate market for farmland. Some displaced residents committed suicide, unable to bear the events. On some occasions, land that TVA had acquired through eminent domain that was expected to be flooded by reservoirs was not flooded, and was instead given away to private developers. The 1960 film Wild River , directed by Elia Kazan , tells

12782-533: The TVA was controversial early on, as some believed its creation was an overreach by the federal government. Supporters of TVA note that the agency's management of the Tennessee River system without appropriated federal funding saves federal taxpayers millions of dollars annually. Opponents, such as Dean Russell in The TVA Idea, in addition to condemning the project as being socialistic , argued that TVA created

12948-492: The TVA. The agency was initially tasked with modernizing the region, using experts and electricity to combat human and economic problems. TVA developed fertilizers, and taught farmers ways to improve crop yields. In addition, it helped replant forests, control forest fires , and improve habitats for fish and wildlife. The Authority hired many of the area's unemployed for a variety of jobs: they conducted conservation , economic development , and social programs . For instance,

13114-714: The Tennessee River for electricity generation and navigation improvements. The National Defense Act of 1916 , signed into law by President Woodrow Wilson , authorized the construction of a hydroelectric dam on the Tennessee River in Muscle Shoals, Alabama , for the purpose of producing nitrates for ammunition. During the 1920s and the 1930s, Americans began to support the idea of public ownership of utilities , particularly hydroelectric power facilities. Many believed privately owned power companies were charging too much for power, did not employ fair operating practices, and were subject to abuse by their owners, utility holding companies, at

13280-435: The Tennessee Valley Authority. Even by Depression standards, the Tennessee Valley was in dire economic straits in 1933. Thirty percent of the population was affected by malaria . The average income in the rural areas was $ 639 per year (equivalent to $ 11,947 in 2024), with some families surviving on as little as $ 100 per year (equivalent to $ 1,870 in 2023). Much of the land had been exhausted by poor farming practices, and

13446-609: The Tennessee Valley largely concentrated on or near TVA reservoirs that include water access points, campgrounds, hiking trails, fishing piers, and equestrian facilities. TVA operates an economic development organization that works with companies and economic development agencies throughout the Tennessee Valley to create jobs via private investments. They also work with businesses to help them choose locations for facilities and expand existing facilities. Services provided include assistance with site selection, employee recruitment and training, and research. A total of seven sites throughout

13612-896: The U.S. West, Peabody operates Powder River Basin operations in Wyoming as well as other mining operations in Arizona and New Mexico. Operations in the U.S. Midwest consist of mines in Indiana and Illinois. Peabody also operates a single underground mine in Colorado. All of these assets are occupied with the mining, preparation, and selling of coal to utility companies or steelmakers. Peabody's Australian operations consist of metallurgical and thermal coal mining operations in Queensland and New South Wales. Purchasers of its coal product include Australian utility companies or steel producers. The Trading and Brokerage function

13778-402: The U.S. federal government, and remains the largest. Under the leadership of David E. Lilienthal , the TVA also became the global model for the United States' later efforts to help modernize agrarian societies in the developing world . The TVA historically has been documented as a success in its efforts to modernize the Tennessee Valley and helping to recruit new employment opportunities to

13944-787: The U.S., Examples include the Sago Mine disaster of 2006, and the 2007 mine accident in Utah 's Crandall Canyon Mine , where nine miners were killed and six entombed. In the decade 2005–2014, US coal mining fatalities averaged 28 per year. The most fatalities during the 2005–2014 decade were 48 in 2010, the year of the Upper Big Branch Mine disaster in West Virginia, which killed 29 miners. Chronic lung diseases, such as pneumoconiosis (black lung) were once common in miners, leading to reduced life expectancy . In some mining countries black lung

14110-560: The US Department of Labor's Mine Safety and Health Administration (MSHA) show that between 1990 and 2004, the industry cut the rate of injuries by more than half and fatalities by two-thirds. But according to the Bureau of Labor Statistics , even in 2006, mining remained the second most dangerous occupation in America, when measured by fatality rate . These numbers, however, include all mining activities, and oil and gas mining contribute to

14276-604: The United States and proposed mines under development. The coal mining industry employs almost 2.7 million workers. The History of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today, but has begun to decline due to

14442-535: The United States Department of the Interior, for their reclamation efforts. In response to federal legislation, such as the 1970 Clean Air Act and the 1990 Clean Air Act amendments, and environmental criticism of its mining operations, Peabody has directed investments in technologies and equipment that serve to mitigate adverse environmental effects of their coal mining operations. In 2007, the company became

14608-563: The United States and the third largest nuclear power fleet, with seven units at three sites . In addition, they also operate four coal-fired power plants , 29 hydroelectric dams, nine simple-cycle natural gas combustion turbine plants, nine combined cycle gas plants, 1 pumped storage hydroelectric plant, 1 wind energy site, and 14 solar energy sites. In fiscal year 2020, nuclear generation made up about 41% of TVA's total energy production, natural gas 26%, coal 14%, hydroelectric 13%, and wind and solar 3%. TVA purchases about 15% of

14774-408: The Valley are certified by TVA as megasites , which contain a minimum of 1,000 acres (4.0 km ), and have access to an Interstate Highway and the potential for rail service, and environmental impact study, and contain or have the potential to contain direct-serve industrial customers. In the late 19th century, the Army Corps of Engineers first recognized a number of potential dam sites along

14940-401: The Valley's electric power needs to continue to grow, TVA began building nuclear power plants in 1966 as a new source of power. The following year, TVA began work on the construction of Tellico Dam , which had been initially conceived in the 1930s and would later become its most controversial project. During the 1970s significant changes occurred in the economy of the Tennessee Valley and

15106-400: The agency's five nuclear reactors return to service, and the institution of a rate freeze that continued for ten years. As the electric-utility industry moved toward restructuring and deregulation , TVA began preparing for competition. It cut operating costs by nearly $ 800 million a year, reduced its workforce by more than half, increased the generating capacity of its plants, and developed

15272-496: The board until the end of the current congressional session (typically in December) or until their successors take office, whichever comes first. The current board members as of January 4, 2023: President Biden has nominated the following to fill a seat on the board. They await Senate confirmation. With a generating capacity of approximately 35 gigawatts (GW), TVA has the sixth highest generation capacity of any utility company in

15438-546: The business and the company was incorporated in the state of Illinois under the name Peabody Coal Company in 1890. In 1895, it began operations of its first mine in Williamson County, Illinois and later expanded its operations in Illinois. In 1913, the company won its first long-term contract to supply Chicago Edison Company, the predecessor to utility Commonwealth Edison . The company's growth continued after World War I and

15604-581: The coal mining jobs as part of a just transition ; however, renewable energy was not suitable in some of the geographies with high concentrations of miners, such as in China, which is far and away the leading coal-mining nation. Coal refuse (also described as coal waste, rock, slag, coal tailings, waste material, rock bank, culm, boney, or gob ) is the material left over from coal mining, usually as tailings piles or spoil tips . For every tonne of hard coal generated by mining, 400 kg (880 lb) of waste material remains, which includes some lost coal that

15770-497: The coal preparation (or wash) plant. Once this strip is empty of coal, the process is repeated with a new strip being created next to it. This method is most suitable for areas with flat terrain. Equipment to be used depends on geological conditions. For example, to remove overburden that is loose or unconsolidated, a bucket wheel excavator might be the most productive. The life of some area mines may be more than 50 years. The contour mining method consists of removing overburden from

15936-804: The coal resource may cause burial and loss of topsoil, exposes parent material, and creates large infertile wastelands. Soil disturbance and associated compaction result in conditions conducive to erosion. Soil removal from the area to be surface-mined alters or destroys many natural soil characteristics, and reduces its biodiversity and productivity for agriculture. Soil structure may be disturbed by pulverization or aggregate breakdown. Top 10 hard and brown coal producers in 2012 were (in million metric tons): China 3,621, United States 922, India 629, Australia 432, Indonesia 410, Russia 351, South Africa 261, Germany 196, Poland 144, and Kazakhstan 122. Coal has been mined in every state of Australia, but mainly in Queensland, New South Wales and Victoria. It

16102-448: The company had approximately 2.4 billion tons of proven and probable coal reserves. Peabody maintains ownership or majority interests in 17 surface and underground mining operations located throughout the United States and Australia. In the United States, company-owned mines are located in Alabama , Colorado , Illinois , Indiana , New Mexico , and Wyoming . Peabody's largest operation is

16268-553: The company reiterated that "the coal supercycle is just getting underway." Peabody reported net losses in excess of $ 500 million annually for each calendar year during 2012 through 2014, and a net loss of nearly $ 2 billion for 2015. For the quarter ended March 31, 2016, Peabody reported a net loss of $ 165 million. Sales revenue decreased by $ 539 million compared to the same period in the prior year, reflecting lower coal prices and reduced demand for steel. The company filed for Chapter 11 bankruptcy on April 13, 2016. In November 2016,

16434-550: The company would be severely impacted. The settlement of the case required the company to revise its financial disclosures with the Securities and Exchange Commission . The settlement did not require any financial penalties or admission of legal wrongdoing. The practice of extracting coal from the earth for energy production purposes has been the subject of controversy for an extended duration of time. The Sierra Club has expressed concern regarding Peabody Energy's initial opposition to

16600-641: The company's nuclear reactor fleet. This includes fuel for the Browns Ferry Nuclear Plant , fuel handling equipment upgrades across the fleet and steam generator replacements at the Watts Bar Nuclear Plant . Framatome will provide its state-of-the-art ATRIUM 11 fuel for the three boiling water reactors at Browns Ferry . This contract makes TVA the third U.S. utility to switch to the ATRIUM 11 fuel design. On August 3, 2020, President Trump fired

16766-575: The corporation went public for the first time in 1929 with a listing on the Midwest Stock Exchange , and in 1949 was listed on the New York Stock Exchange . Despite being ranked eighth among the country's top coal producers in the mid-1950s, Peabody began to lose market share to companies operating cost-efficient surface mining operations. To address the situation, it entered into merger talks with Sinclair Coal Company. A merger between

16932-506: The day after Donald Trump won the US presidential election, shares of Peabody Energy surged more than 50 percent. On April 3, 2017 it emerged from bankruptcy and started trading on the NYSE with a ticker symbol of BTU. All figures in the following "Net Income (Loss)" table were obtained from Peabody's Form 10-K for periods ended December 31, 2014, and December 31, 2019, as filed with the U.S. Securities and Exchange Commission . In October 2017,

17098-429: The developed world. Modern coal mining in the US has an average 23 deaths per year due to mine accidents (2001–2020). However, in lesser developed countries and some developing countries, many miners continue to die annually, either through direct accidents in coal mines or through adverse health consequences from working under poor conditions. China , in particular, has the highest number of coal mining related deaths in

17264-455: The disruptive activities of blasting, ripping, and excavating coal. Stripping of overburden eliminates and destroys archeological and historic features, unless they are removed beforehand. The removal of vegetative cover and activities associated with the construction of haul roads, stockpiling of topsoil, displacement of overburden and hauling of soil and coal increase the quantity of dust around mining operations. Dust degrades air quality in

17430-402: The expense of consumers. The concept of government-owned generation facilities selling to publicly owned distribution utilities was controversial, and remains so today. The private sector practice of forming utility holding companies had resulted in them controlling 94 percent of generation by 1921, and they were essentially unregulated. In an effort to change this, Congress and Roosevelt enacted

17596-571: The fatalities occurring in the first half of the 20th century. 3,242 died in 1907, the worst year ever; in 2020 there were five. Open cut hazards are principally mine wall failures and vehicle collisions; underground mining hazards include suffocation, gas poisoning, roof collapse, rock burst , outbursts , and gas explosions. Firedamp explosions can trigger the far more dangerous coal dust explosions, which can engulf an entire mine. Most of these risks are greatly reduced in modern mines, and multiple fatality incidents are now rare in most parts of

17762-409: The federal Office of Surface Mining that Peabody Energy's self-bonding remained adequate. Before Peabody Energy declared bankruptcy it held $ 1.47 billion in self-bonding liabilities, including $ 900.5 million in Wyoming alone. In 2016, Peabody reached settlement agreements with Illinois, Wyoming, New Mexico, and Indiana related to its self-bonding obligations. Kelly Mader represented Peabody Energy on

17928-457: The genetic soil profile, displaces or destroys wildlife and habitat, alters current land uses, and to some extent permanently changes the general topography of the area mined. Adverse impacts on geological features of human interest may occur in a coal strip mine. Geomorphic and geophysical features and outstanding scenic resources may be sacrificed by indiscriminate mining. Paleontological, cultural, and other historic values may be endangered due to

18094-483: The ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa , a coal mine and its structures are a colliery , a coal mine is called a "pit", and above-ground mining structures are referred to as

18260-690: The group $ 5 million (equivalent to $ 11.5 million in 2023 ), but denied wrongdoing. TVA has received criticism throughout its entire history for what some have perceived as excessive use of its authority of eminent domain and an unwillingness to compromise with landowners. All of TVA's hydroelectric projects were made possible through the use of eminent domain, and displaced more than 125,000 Tennessee Valley residents. Residents who initially refused to sell their land were often forced to do so via court orders and lawsuits. Many of these projects also inundated historic Native American sites and early Colonial -era settlements. Historians have claimed that

18426-495: The hiring of one woman for every three inexperienced men until women constituted 20 percent of the workforce. This legal strategy was successful. Almost 3,000 women were hired by the close of 1979 as underground miners. In the 1980s, Peabody expanded its operations in the Eastern United States, acquiring the West Virginia coal mines of Armco in 1984. The company sought to broaden its metallurgical coal portfolio through

18592-450: The immediate area, has an adverse impact on vegetative life, and constitutes health and safety hazards for mine workers and nearby residents. Surface mining disrupts virtually all aesthetic elements of the landscape. Alteration of land forms often imposes unfamiliar and discontinuous configurations. New linear patterns appear as material is extracted and waste piles are developed. Different colors and textures are exposed as vegetative cover

18758-455: The implementation of new equipment and procedures that reduced sulfur dioxide emissions. Stricter requirements outlined in Phase II of the legislation also prompted Peabody to invest in emissions-reducing technologies. In 1990, the U.K.-based conglomerate Hanson , one of the owners of Peabody Holding at the time, bought out the rest of the owners. In 1993, Peabody Energy expanded their holdings in

18924-468: The intent of also controlling floods, greatly improved the lives of farmers and rural residents, making their lives easier and farms in the Tennessee Valley more productive. They also provided new employment opportunities to the poverty-stricken regions in the Valley. At the same time, however, they required the displacement of more than 125,000 valley residents or roughly 15,000 families, as well as some cemeteries and small towns, which caused some to oppose

19090-570: The investigation. In 1963, U.S. Senator and Republican presidential candidate Barry Goldwater was quoted in a Saturday Evening Post article by Stewart Alsop as saying, "You know, I think we ought to sell TVA." He had called for the sale to private companies of particular parts of the Authority, including its fertilizer production and steam-generation facilities, because "it would be better operated and would be of more benefit for more people if it were part of private industry." Goldwater's quotation

19256-460: The late 18th century onward, with further progress being driven by 19th-century and early 20th-century progress. However, oil and gas were increasingly used as alternatives from the 1860s onward. By the late 20th century, coal was, for the most part, replaced in domestic as well as industrial and transportation usage by oil , natural gas or electricity produced from oil, gas, nuclear power or renewable energy sources. By 2010, coal produced over

19422-522: The late 1940s and early 1950s, however. TVA was one of the first federal hydropower agencies, and was quickly hailed as a success. While most of the nation's major hydropower systems are federally managed today, other attempts to create similar regional corporate agencies have failed. The most notable was the proposed Columbia Valley Authority for the Columbia River in the Pacific Northwest , which

19588-404: The majority of fatalities. Coal mining resulted in 47 fatalities that year. One study, though, has suggested that hazards of modern mining are now more accretive with workers facing long-term health impacts, such as sleep deprivation, that build up over time. Strip mining severely alters the landscape, which reduces the value of the natural environment in the surrounding land. The land surface

19754-461: The method of extraction. For example, a study has found that among surface coal mine operations, dragline equipment produced the loudest sound at a range of 88–112 dBA. Within longwall sections, stageloaders used to transport coal from the mining face and shearers used for extraction represent some of the highest noise exposures. Auxiliary fans (up to 120 dBA), continuous mining machines (up to 109 dBA), and roof bolters (up to 103 dBA) represent some of

19920-465: The mining workforce. in 2015 US coal mines had 65,971 employees, the lowest figure since EIA began collecting data in 1978. However, a 2016 study reported that a relatively minor investment would allow most coal workers to retrain for the solar energy industry. Coal mining has been a very dangerous activity and the list of historical coal mining disasters is long. In the U.S., 104,895 coal miners were killed in mine accidents since 1900, 90 percent of

20086-501: The name The Energy Group . When TXU acquired The Energy Group, Peabody was sold to Lehman Brothers Merchant Banking Partners . The company filed an initial public offering (IPO) in May 2001, and since this time it has operated as a publicly traded company. In 2002, Peabody launched its Peabody Energy Australia Coal Co. following the acquisition of the Wilkie Creek Mine in Queensland's Surat Basin . The North Goonyella coal mine

20252-501: The nation's largest electricity supplier. Even so, the demand for electricity was outstripping TVA's capacity to produce power from hydroelectric dams, and so TVA began to construct additional coal-fired plants. Political interference kept TVA from securing additional federal appropriations to do so, so it sought the authority to issue bonds. Several of TVA's coal-fired plants, including Johnsonville , Widows Creek , Shawnee , Kingston , Gallatin , and John Sevier , began operations in

20418-411: The nation, prompted by energy crises in 1973 and 1979 and accelerating fuel costs throughout the decade. The average cost of electricity in the Tennessee Valley increased fivefold from the early 1970s to the early 1980s. TVA's first nuclear reactor, Browns Ferry Unit 1 , began commercial operation on August 1, 1974. Between 1970 and 1974, TVA set out to construct a total of 17 nuclear reactors, due to

20584-469: The noisiest equipment within continuous mining sections. Exposures to noise exceeding 90 dBA can lead to adverse effects on workers' hearing. The use of administrative controls and engineering controls can be used to reduce noise exposures. Improvements in mining methods (e.g. longwall mining), hazardous gas monitoring (such as safety-lamps or more modern electronic gas monitors), gas drainage, electrical equipment , and ventilation have reduced many of

20750-426: The officials had to find leaders in the communities and convince them that crop rotation and the judicious application of fertilizers could restore soil fertility. Once they had convinced the leaders, the rest followed. TVA immediately embarked on the construction of several hydroelectric dams, with the first, Norris Dam in upper East Tennessee , breaking ground on October 1, 1933. These facilities, designed with

20916-512: The only non-Chinese equity partner in the 650-megawatt near-zero emissions GreenGen clean-coal project in Tianjin , China. Peabody has also invested in the development of carbon capture technologies and coal-to-gas and coal-to-hydrogen projects. In 2014, Peabody Energy's CEO told a coal industry conference that coal-fired electricity generation would bring public health benefits in developing nations, specifically improving cold-chain refrigeration of

21082-585: The open pit methods, due to thickness of the seam 20–25 metres (60–90 feet). Coals occurring below 90 m (300 ft) are usually deep mined. However, there are open pit mining operations working on coal seams up to 300–460 metres (1,000–1,500 feet) below ground level, for instance Tagebau Hambach in Germany. When coal seams are near the surface, it may be economical to extract the coal using open-cut , also referred to as open-cast, open-pit, mountaintop removal or strip, mining methods. Opencast coal mining recovers

21248-421: The operation reaches a predetermined stripping ratio (tons of overburden/tons of coal), it is not profitable to continue. Depending on the equipment available, it may not be technically feasible to exceed a certain height of highwall. At this point, it is possible to produce more coal with the augering method in which spiral drills bore tunnels into a highwall laterally from the bench to extract coal without removing

21414-408: The overburden. Mountaintop coal mining is a surface mining practice involving removal of mountaintops to expose coal seams, and disposing of associated mining overburden in adjacent "valley fills." Valley fills occur in steep terrain where there are limited disposal alternatives. Mountaintop removal mining combines area and contour strip mining methods. In areas with rolling or steep terrain with

21580-835: The planned nuclear plants put the agency in deep financial trouble. In an effort to restructure and improve efficiency and financial stability, TVA began shifting towards a more corporate environment in the latter 1980s. Marvin Travis Runyon , a former corporate executive in the automotive industry , became chairman of the TVA in January 1988, and pledged to stabilize the agency financially. During his four-year term he worked to reduce management layers, and reduced overhead costs by more than 30%, which required thousands of workers to be laid off and many operations transferred to private contractors. These moves resulted in cumulative savings and efficiency improvements of $ 1.8 billion (equivalent to $ 3.51 billion in 2023 ). His tenure also saw three of

21746-425: The potential to spontaneously ignite. Because most coal refuse harbors toxic components, it is not easily reclaimed by replanting with plants like beach grasses. The use of sophisticated sensing equipment to monitor air quality is common and has replaced the use of small animals such as canaries, often referred to as " miner's canaries ". In the United States, the increase in technology has significantly decreased

21912-453: The power it sells from other power producers, which includes power from combined cycle natural gas plants, coal plants, and wind installations, and other renewables. The cost of Purchased Power is part of the "Fuel Cost Adjustment" (FCA) charge that is separate from the TVA Rate. In addition, the Watts Bar Nuclear Plant is the only facility in the country to industrially produce tritium , which

22078-642: The program was used as the basis for modernization programs in various parts of the third world during the Cold War , such as in the Mekong Delta in Vietnam , its failure brought a backlash of cynicism toward modernization programs that has persisted. In 1953, President Dwight D. Eisenhower referred to the TVA as an example of "creeping socialism". The following year, then-film actor and later 40th President Ronald Reagan began hosting General Electric Theater , which

22244-434: The projects, especially in rural areas. The projects also inundated several Native American archaeological sites, and graves were reinterred at new locations, along with new tombstones. The available electricity attracted new industries to the region, including textile mills , providing desperately needed jobs, many of which were filled by women. A few regions of the Tennessee Valley did not receive electricity until

22410-565: The purchase of Eastern Gas and Fuel Associates' seven West Virginia mines in 1987. Peabody also expanded westward, opening the North Antelope and Rochelle mines in the low sulfur Wyodak seam in the heart of Wyoming 's Powder River Basin in 1983 and 1984, respectively. The passage of the Clean Air Act amendments in 1990 prompted the closure of some Peabody mines. However, other mines under its ownership were able to remain in operation due to

22576-526: The region through power generation, flood control, navigation assistance, fertilizer manufacturing, and agricultural development. Since the Depression years, it has developed primarily into a power utility. Despite its shares being owned by the federal government, TVA operates like a private corporation, and receives no taxpayer funding. The TVA Act authorizes the company to use eminent domain . TVA provides electricity to approximately ten million people through

22742-497: The region. Historians have criticized its use of eminent domain and the displacement of over 125,000 Tennessee Valley residents to build the agency's infrastructure projects. The Tennessee Valley Authority is a government-owned corporation created by U.S. Code Title 16 , Chapter 12A, the Tennessee Valley Authority Act of 1933. It was initially founded as an agency to provide general economic development to

22908-399: The risks of rock falls, explosions, and unhealthy air quality. Gases released during the mining process can be recovered to generate electricity and improve worker safety with gas engines . Another innovation in recent years is the use of closed circuit escape respirators , respirators that contain oxygen for situations where mine ventilation is compromised. Statistical analyses performed by

23074-459: The same time, and design and construction employment reached a total of 28,000. In its first eleven years, TVA constructed a total of 16 hydroelectric dams. During the war, the agency also provided 60% of the elemental phosphorus used in munitions, produced maps of approximately 500,000 square miles (1,300,000 km ) of foreign territory using aerial reconnaissance , and provided mobile housing for war workers. The largest project of this period

23240-418: The seam for roof and floor conditions; topography, especially altitude and slope; climate; land ownership as it affects the availability of land for mining and access; surface drainage patterns; groundwater conditions; availability of labor and materials; coal purchaser requirements in terms of tonnage, quality, and destination; and capital investment requirements. Surface mining and deep underground mining are

23406-565: The seam in a pattern following the contours along a ridge or around the hillside. This method is most commonly used in areas with rolling to steep terrain. It was once common to deposit the spoil on the downslope side of the bench thus created, but this method of spoil disposal consumed much additional land and created severe landslide and erosion problems. To alleviate these problems, a variety of methods were devised to use freshly cut overburden to refill mined-out areas. These haul-back or lateral movement methods generally consist of an initial cut with

23572-545: The soil was eroded and depleted. Crop yields had fallen, reducing farm incomes. The best timber had been cut, and 10% of forests were lost to fires each year. President Franklin Delano Roosevelt signed the Tennessee Valley Authority Act (ch. 32, Pub. L.   73–17 , 48  Stat.   58 , enacted May 18, 1933 , codified as amended at 16 U.S.C.   § 831 , et seq.), creating

23738-432: The spoil deposited downslope or at some other site and spoil from the second cut refilling the first. A ridge of undisturbed natural material 15 to 20 ft (5 to 6 m) wide is often intentionally left at the outer edge of the mined area. This barrier adds stability to the reclaimed slope by preventing spoil from slumping or sliding downhill. The limitations of contour strip mining are both economic and technical. When

23904-543: The states includes regulation of streams and that controlling floods is required for keeping streams navigable; it also upheld the constitutionality of the TVA under the War Powers Clause , seeing its activities as a means of assuring the electric supply for the manufacture of munitions in the event of war. The argument before the court was that electricity generation was a by-product of navigation and flood control and therefore could be considered constitutional. The CEO of

24070-414: The strength of opposing interest groups also mattered. The TVA bill was able to attain passage because reformers like Norris skillfully coordinated action at potential choke points and weakened the already disorganized opponents among the electric power industry lobbyists. In 1936, after regrouping, opposing river lobbyists and members of congress who were part of the conservative coalition took advantage of

24236-556: The strong contribution coal plays in global warming and environmental issues, which result in decreasing demand and in some geographies, peak coal . Compared to wood fuels , coal yields a higher amount of energy per unit mass, specific energy or massic energy, and can often be obtained in areas where wood is not readily available. Though it was used historically as a domestic fuel, coal is now used mostly in industry, especially in smelting and alloy production, as well as electricity generation . Large-scale coal mining developed during

24402-476: The surface or overburden, of the mining area. The overburden is then removed by draglines or by shovel and truck. Once the coal seam is exposed, it is drilled, fractured and thoroughly mined in strips. The coal is then loaded onto large trucks or conveyors for transport to either the coal preparation plant or directly to where it will be used. Most open cast mines in the United States extract bituminous coal . In Canada, Australia, and South Africa, open cast mining

24568-523: The two at Sequoyah coming back online three years later and Browns Ferry's three reactors coming back online in 1991, 1995 and 2007. Construction of the Tellico Dam raised political and environmental concerns, as laws had changed since early development in the valley. Scientists and other researchers had become more aware of the massive environmental effects of the dams and new lakes, and worried about preserving habitats and species. The Tellico Dam project

24734-524: The two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden, and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 55 m (180 ft), are usually surface mined. Coal that occurs at depths of 55 to 90 m (180 to 300 ft) are usually deep mined, but in some cases surface mining techniques can be used. For example, some western U.S. coal that occur at depths in excess of 60 m (200 ft) are mined by

24900-477: The two companies occurred in 1955, resulting in the transfer of Peabody's headquarters to St. Louis, Missouri . The merged company retained the Peabody name. Under the leadership of chairman Russell Kelce, the company expanded production and sales. In 1962, Peabody expanded into the Pacific with the opening of mining operations in Queensland , Australia. During this period Peabody also forged an equity partnership with

25066-633: The two plants would reduce its carbon output by about 4.4% annually. TVA announced in April 2021 plans to completely phase out coal power by 2035. The following month, the board voted to consider replacing almost all of their operating coal facilities with combined-cycle gas plants. Such plants considered for gas plant redevelopment include the Cumberland, Gallatin, Shawnee, and Kingston facilities. In early February 2020, TVA awarded an outside company, Framatome , several multi-million-dollar contracts for work across

25232-512: The underground Navajo Aquifer (N-aquifer) to supply the slurry pipeline, a solution that generated controversy. The Navajo Aquifer is a main source of potable water for the Navajo and Hopi tribes, who use the water for farming and livestock maintenance as well as drinking and other domestic uses. Members of the tribes as well as outside environmental groups have alleged that the pumping of water by Peabody Energy has caused contamination of water sources and

25398-488: The war effort. However, the abundance of TVA power was one of the major factors in the decision by the U.S. Army to locate uranium enrichment facilities in Oak Ridge, Tennessee , for the world's first atomic bombs . This was part of an effort codenamed the Manhattan Project . By the end of World War II, TVA had completed a 650-mile (1,050 km) navigation channel the length of the Tennessee River and had become

25564-441: The world, with official statistics claiming that 6,027 deaths occurred in 2004. To compare, 28 deaths were reported in the U.S. in the same year. Coal production in China is twice that in the US, while the number of coal miners is around 50 times that of the US, making deaths in coal mines in China 4 times as common per worker (108 times as common per unit output) as in the US. Mine disasters have still occurred in recent years in

25730-442: Was acquired by Peabody in 2004. In October 2006, Peabody completed an acquisition of Excel Coal Limited, an independent coal company in Australia. Peabody paid $ 1.52 billion for Excel and also assumed $ 227 million of Excel's debt. At the time, Excel owned three operating mines and three development-stage mines in Australia. Additionally, Excel had an estimated 500 million tons of proven and probable coal reserves. The company advanced

25896-781: Was also the subject of criticism in John Prine 's 1971 song " Paradise ." In Newsweek 's 2011 rankings of the least eco-friendly companies in the US, Peabody Energy was ranked #9 out of the top 500 largest US companies based on their environmental impact. Peabody launched its first land reclamation program, Operation Green Earth, in 1954. Since then, Peabody's activities in regards to the pursuit of its mission, specifically concerning environmental sustainability practices, have been recognized by regulators and industry groups, but have raised concerns among its critics, primarily environmental advocacy organizations. The company has taken steps to enact environmental restoration and has been recognized by

26062-462: Was completed in 2015 at a cost of more than $ 1 billion, was the largest industrial spill in United States history, and considered one of the worst environmental disasters of all time. A 2009 report by engineering firm AECOM found a number of inadequate design factors of the ash pond were responsible for the spill, and in August 2012, TVA was found liable for the disaster by the U.S. District Court for

26228-615: Was initially delayed because of concern over the snail darter , a small ray-finned fish which had been discovered in the Little Tennessee River in 1973 and listed as an endangered species two years later. A lawsuit was filed under the Endangered Species Act and the U.S. Supreme Court ruled in favor of protecting the snail darter in Tennessee Valley Authority v. Hill in 1978. The project's main motive

26394-531: Was mined, and 375.1 million tonnes was exported. In 2013/14, coal provided about 69% of Australia's electricity production. In 2013, Australia was the world's fifth-largest coal producer, after China, the United States, India, and Indonesia. However, in terms of proportion of production exported, Australia is the world's second largest coal exporter, as it exports roughly 73% of its coal production. Indonesia exports about 87% of its coal production. A court in Australia has cited climate change in ruling against

26560-477: Was modeled off of TVA, but did not gain approval. In order to provide the power for essential industries during World War II , TVA engaged in one of the largest hydropower construction programs ever undertaken in the U.S. This was especially important for the energy-intensive aluminum industry, which was used in airplanes and munitions. By early 1942, when the effort reached its peak, 12 hydroelectric plants and one coal-fired steam plant were under construction at

26726-528: Was ranked 493rd out of 500 in all industries and 29th out of 31 in the energy industry. The company received the worst possible Environmental Impact score. Peabody Energy often used "self-bonding" to guarantee it could pay for its mine reclamation obligations under the Surface Mining Control and Reclamation Act of 1977 . On March 28, 2016 the Wyoming Department of Environmental Quality assured

26892-461: Was sponsored by General Electric (GE). He was fired in 1962 after publicly referring to the TVA, which was a major customer for GE turbines, as one of the problems of "big government". Some claim that Reagan was instead fired due to a criminal antitrust investigation involving him and the Screen Actors Guild . However, Reagan was only interviewed; nobody was actually charged with anything in

27058-467: Was the Fontana Dam . After negotiations led by then-Vice President Harry Truman , TVA purchased the land from Nantahala Power and Light, a wholly owned subsidiary of Alcoa , and built Fontana Dam. Also in 1942, TVA's first coal-fired plant, the 267-megawatt Watts Bar Steam Plant , began operation. The government originally intended the electricity generated from Fontana to be used by Alcoa factories for

27224-401: Was the first new nuclear reactor to enter service in the United States in the 21st century. On December 22, 2008, an earthen dike impounding a coal ash pond at TVA's Kingston Fossil Plant failed, releasing 1.1 billion US gallons (4,200,000 m ) of coal ash slurry across 300 acres (1.2 km ) of land and into two tributaries of the Tennessee River. The spill, of which cleanup

27390-471: Was to support recreational and tourism development, unlike earlier dams constructed by TVA. Land acquired by eminent domain for the Tellico Dam and its reservoir that encountered minimal inundation was sold to private developers for the construction of present-day Tellico Village , a planned retirement community . The inflation crises of the 1970s and early 1980s, combined with the cancellation of several of

27556-502: Was used against him in a TV ad by Doyle Dane Bernbach for then-President Lyndon B. Johnson 's 1964 campaign , which depicted an auction taking place atop a dam and promised that Johnson would not sell TVA. The TVA has faced multiple constitutional challenges. The United States Supreme Court ruled TVA to be constitutional in Ashwander v. Tennessee Valley Authority (297 U.S. 288) in 1936. The Court noted that regulating commerce among
