Fossil fuel power plant in the context of "Fuel efficiency"

A cenosphere or kenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, typically produced as a coal combustion byproduct at thermal power plants. The color of cenospheres varies from gray to almost white and their density is about 0.4–0.8 g/cm (0.014–0.029 lb/cu in), which gives them a great buoyancy.

Cenospheres are hard and rigid, light, waterproof and insulative. This makes them highly useful in a variety of products, notably fillers.

The Kingston Fossil Plant Spill was an environmental and industrial disaster that occurred on December 22, 2008, when a dike ruptured at a coal ash pond at the Tennessee Valley Authority's Kingston Fossil Plant in Roane County, Tennessee, releasing 1.1 billion US gallons (4.2 million cubic metres) of coal fly ash slurry. The coal-fired power plant, located across the Clinch River from the city of Kingston, used a series of ponds to store and dewater the fly ash, a byproduct of coal combustion. The spill released a slurry of fly ash and water which traveled across the Emory River and its Swan Pond embayment onto the opposite shore, covering up to 300 acres (1.2 km) of the surrounding land. The spill damaged multiple homes and flowed into nearby waterways including the Emory River and Clinch River, both tributaries of the Tennessee River. It was the largest industrial spill in United States history.

The initial spill, which resulted in millions of dollars' worth of property damages and rendered many properties uninhabitable, cost TVA more than $1 billion to clean up and was declared complete in 2015. TVA was found liable for the spill in August 2012 by the U.S. District Court for 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, including brain cancer, lung cancer, and leukemia, as a result of exposure to the toxic coal ash, and more than 30 had died within 10 years of the spill. 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. After rejecting multiple offers, workers reached a settlement with the contractor in May 2023.

Battersea Power Station is a decommissioned coal-fired power station located on the south bank of the River Thames in Nine Elms, Battersea in the London Borough of Wandsworth. It was built by the London Power Company (LPC) to the design of Leonard Pearce, Engineer in Chief to the LPC, and CS Allott & Son Engineers. The architects were J. Theo Halliday and Giles Gilbert Scott. The station is one of the world's largest brick buildings and notable for its original, Art Deco interior fittings and decor.

The building comprises two power stations, built in two stages, in a single building. Battersea A Power Station was built between 1929 and 1935 and Battersea B Power Station, to its east, between 1937 and 1941, when construction was paused owing to the worsening effects of the Second World War. The building was completed in 1955. "Battersea B" was built to a design nearly identical to that of "Battersea A", creating the iconic four-chimney structure.

Kilroot power station is a fossil fuel power plant on the north shore of Belfast Lough at Kilroot near Carrickfergus in County Antrim, Northern Ireland. The plant currently has a 141 megawatt (MW) capacity from four standby gas turbines and a 10 MW battery energy storage capacity from the Kilroot Advancion Energy Storage Array.

When coal power generation stopped in September 2023, it was the only remaining coal-fired power station operating in Northern Ireland, and it had a 560 megawatt (MW) capacity from dual coal and oil fuelled generators. The station once produced a third of the country's electricity, and was also one of County Antrim's top 100 employers in 2010 (or before).
