Fossil fuel power station - Wikipedia

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.

Particulates - Wikipedia

Sources of atmospheric particulate matter. Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation and sea spray.Human activities, such as the burning of fossil fuels in vehicles, stubble burning, power plants, road dust, wet cooling towers in cooling systems and various industrial processes, also generate significant amounts of

Energy policy of the United States - Wikipedia

Natural gas. The United States is a net importer of natural gas, most of it by pipeline from Canada, with a smaller amount of LNG from other sources. Net gas imports into the US peaked in 2007, when the country imported 16.4 percent of the natural gas it consumed, and was the world's largest net importer of natural gas.

Central heating - Wikipedia

In much of the temperate climate zone, most detached housing has had central heating installed since before the Second World War. Where coal was readily available (i.e. the anthracite coal region in northeast Pennsylvania) coal-fired steam or hot water systems were common. Later in the 20th century, these were updated to burn fuel oil or gas, eliminating the need for a large coal storage bin

Natural gas - Wikipedia

Natural gas (also called fossil gas; sometimes just gas) is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and

Climate change mitigation - Wikipedia

Climate change mitigation consists of actions to limit global warming and its related effects.This involves reductions in human emissions of greenhouse gases (GHGs) as well as activities that reduce their concentration in the atmosphere.. Fossil fuel combustion accounts for 89% of all CO 2 emissions and 68% of all GHG emissions. The most important challenge is to eliminate the use of coal, oil
