Fossil fuels or mineral fuels are hydrocarbons found within the top layer of the earth’s Crust (geology). They range from very volatile materials with low carbon:hydrogen ratios like methane, to liquid petroleum to nonvolatile materials composed of almost pure carbon, like anthracite coal. It is generally accepted that they formed from the fossil of dead plants and animals by exposure to heat and pressure in the Earth's crust over hundreds of millions of years. This is known as the Petroleum#Biogenic theory and was first introduced by Mikhail Lomonosov in 1757. There is an opposing theory that the more volatile hydrocarbons, especially natural gas, are formed by Abiogenic petroleum origin processes, that is no living material was involved in their formation.

It was estimated that in 2004 86% of human-produced energy came from burning fossil fuels.

Fossil fuels are non-renewable resources because they take millions of years to form and reserves are being depleted much faster than new ones are being formed. Concern about fossil fuel supplies is one of the causes of regional and global conflicts. The production and use of fossil fuels raise environmental concerns. A global movement toward the generation of renewable energy is therefore under way to help meet increased energy needs.

The burning of fossil fuels produces around 6.3 billion metric tons (= 6.3 gigatons) of carbon dioxide per year, but it is estimated that natural processes can only absorb about half of that amount so there is a net increase of 3.2 billion tonnes of atmospheric carbon dioxide per year. Carbon dioxide is one of the greenhouse gases that enhances radiative forcing and contributes to global warming raising concerns that solar heat will be trapped and the average surface temperature of the Earth will rise in response. Origin According to the biogenic theory, oil is formed from the preserved remains of prehistory zooplankton and algae which have been settled to the sea (or lake) bottom in large quantities under anoxic sea water. Over geologic time scale this organic compound matter, mixed with mud, is buried under heavy layers of sediment. The resulting high levels of heat and pressure cause the organic matter to chemically change during diagenesis, first into a waxy material known as kerogen which is found in various oil shales around the world, and then with more heat into liquid and gaseous hydrocarbons in a process known as catagenesis (geology). Terrestrial plants, on the other hand, tend to form coal. Many of the coal fields date to the carboniferous period.

Importance Fossil fuels are of great importance because they can be burned (oxidized to carbon dioxide and water), producing significant amounts of energy. The use of coal as a fuel predates recorded history. Semisolid hydrocarbons from seeps were also burned in ancient times, but these materials were mostly used for waterproofing and embalming. {{Citation| last = Bilkadi | first = Zayn | year =1994 | title = BULLS FROM THE SEA : Ancient Oil Industries | publisher = Aramco World | url = http://www.gr8dubai.com/oil2.htm | accessdate =2007-09-09 --> Commercial exploitation of petroleum, largely as a replacement for oils from animal sources (notably whale oil) for use in oil lamps began in the nineteenth century.

Prior to the latter half of the eighteenth century windmills or watermills provided the energy needed for industry such as milling flour, sawmill or pumping water, and burning wood or peat provided domestic heat. The wide scale use on fossil fuels, coal at first and petroleum later, to fire steam engines enabled the Industrial Revolution. At the same time Gas lighting using natural gas or coal gas were coming into wide use. The invention of the internal combustion engine and its use in automobiles and trucks greatly increased the demand for gasoline and diesel, both made from fossil fuels. Other forms of transportation, rail transport and aircraft also required fossil fuels. The other major use for fossil fuels is in Electrical power industry.

Fossil fuels are also the main source of raw materials for the petrochemical industry.

Limits and alternatives emission by fuel type, 1800-2000 AD.The principle of supply and demand suggests that as hydrocarbon supplies diminish, prices will rise. Therefore higher prices will lead to increased alternative, renewable energy supplies as previously uneconomic sources become sufficiently economical to exploit. Artificial gasolines and other renewable energy sources currently require more expensive production and processing technologies than conventional petroleum reserves, but may become economically viable in the near future. See Future energy development.Different alternative sources of energy include alcohols, hydrogen, Nuclear power, hydroelectric, solar, wind, and Geothermal power.

Levels and flows Levels of primary energy sources are the reserves in the ground. Flows are production. The most important part of primary energy sources are the carbon based fossil energy sources. Oil, coal, and gas stood for 79.6% of primary energy production during 2002 (in million tonnes of oil equivalent (mtoe)) (34.9+23.5+21.2).

Levels (reserves) ( EIA oil, gas, coal estimates, EIA oil, gas estimates)



Flows (daily production) during 2002 (7.9 is a ratio to convert tonnes of oil equivalent to barrels of oil equivalent)

Years of production left in the ground with the most optimistic reserve estimates (Oil & Gas Journal, World Oil)

Note that this calculation assumes that the product could be produced at a constant level for that number of years and that all of the reserves could be recovered. In reality, consumption of all three resources has been increasing. While this suggests that the resource will be used up more quickly, in reality, the production curve is much more akin to a bell curve. At some point in time, the production of each resource within an area, country, or globally will reach a maximum value, after which, the production will decline until it reaches a point where is no longer economically feasible or physically possible to produce. See Hubbert peak theory for detail on this decline curve with regard to petroleum.

The above discussion emphasizes worldwide energy balance. It is also valuable to understand the ratio of reserves to annual consumption (R/C) by region or country. For example, energy policy of the United Kingdom recognizes that Europe's R/C value is 3.0, very low by world standards, and exposes that region to energy vulnerability. Specific alternatives to fossil fuels are a subject of intense debate worldwide.

Environmental effects In the United States, more than 90% of greenhouse gas emissions come from the combustion of fossil fuels.US EPA.2000. Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-1998, Rep. EPA 236-R-00-01. US EPA, Washington, DC, http://www.epa.gov/globalwarming Combustion of fossil fuels also produces other air pollutants, such as nitrogen oxides, sulphur dioxide, volatile organic compounds and heavy metals.

According to Environment Canada:"The electricity sector is unique among industrial sectors in its very large contribution to emissions associated with nearly all air issues. Electricity generation produces a large share of Canadian nitrogen oxides and sulphur dioxide emissions, which contribute to smog and acid rain and the formation of fine particulate matter. It is the largest uncontrolled industrial source of mercury emissions in Canada. Fossil fuel-fired electric power plants also emit carbon dioxide, which may contribute to climate change. In addition, the sector has significant impacts on water and habitat and species. In particular, hydro dams and transmission lines have significant effects on water and biodiversity."

Combustion of fossil fuels generates sulphuric, carbonic, and nitric acids, which fall to Earth as acid rain, impacting both natural areas and the built environment. Monuments and sculptures made from marble and limestone are particularly vulnerable, as the acids dissolve calcium carbonate.

Fossil fuels also contain radioactive materials, mainly uranium and thorium, that are released into the atmosphere. In 2000, about 12,000 metric tons of thorium and 5,000 metric tons of uranium were released worldwide from burning coal. Coal Combustion: Nuclear Resource or Danger - Alex Gabbard It is estimated that during 1982, US coal burning released 155 times as much radioactivity into the atmosphere as the Three Mile Island incident. Nuclear proliferation through coal burning - Gordon J. Aubrecht, II, Ohio State University

Burning coal also generates large amounts of bottom ash and fly ash. These materials are used in a wide variety of Fly ash#Fly ash reuse, utilizing, for example, about 40% of the US production.

Harvesting, processing, and distributing fossil fuels can also create environmental problems. Coal mining methods, particularly mountaintop removal and strip mining, have extremely negative environmental impacts, and offshore oil drilling poses a hazard to aquatic organisms. Oil refinery also have negative environmental impacts, including air and water polluition. Transportation of coal requires the use of diesel-powered locomotives, while crude oil is typically transported by tanker ships, each of which requires the combustion of additional fossil fuels.

Environmental regulation uses a variety of approaches to limit these emissions, such as command-and-control (which mandates the amount of pollution or the technology used), economic incentives, or voluntary programs.

An example of such regulation in the USA is the "EPA is implementing policies to reduce airborne mercury emissions. Under regulations issued in 2005, coal-fired power plants will need to reduce their emissions by 70 percent by 2018.".

In economic terms, pollution from fossil fuels is regarded as a negative externality. Taxation is considered one way to make societal costs explicit, in order to 'internalize' the cost of pollution. This aims to make fossil fuels more expensive, thereby reducing their use and the amount of pollution associated with them, along with raising the funds necessary to counteract these factors. Although European nations impose some pollution taxes, they also give billions of subsidies to the fossil fuel industry, offsetting the taxes.

Many in America believe that a move away from an economy that is solely dependent on fossil fuels will allow a more even-handed approach to foreign policy. Former CIA Director James Woolsey recently outlined the national security arguments in favor of moving away from fossil fuels. Video of Woolsey speech
