Fossil fuels, also known as mineral fuels, are hydrocarbon-containing natural resources such as coal, oil and natural gas. The utilization of fossil fuels has fueled industrial development and largely supplanted water driven mills, as well as the combustion of wood or peat for heat.

Railyard in the port of Ashtabula Ashtabula is a city located in Ashtabula County, Ohio, and the center of the Ashtabula Micropolitan Statistical Area (as defined by the United States Census Bureau in 2003). ... Hydrocarbons are refined at oil refineries and chemical plants In chemistry, a hydrocarbon is any chemical compound that consists only of the elements carbon (C) and hydrogen (H). ... Media:Example. ... Pumpjack pumping an oil well near Sarnia, Ontario Petroleum (from Greek petra â€“ rock and elaion â€“ oil or Latin oleum â€“ oil ), crude oil, sometimes colloquially called black gold or Texas Tea, is a thick, dark brown or greenish liquid. ... Many stoves use natural gas. ... A tree trunk as found at the Veluwe, The Netherlands Wood derives from woody plants, notably trees but also shrubs. ... Peat in Lewis, Scotland Peat is an accumulation of partially decayed vegetable matter. ...

When generating electricity, energy from the combustion of fossil fuels is often used to power a turbine. Older generators often used steam generated by the burning of the fuel to turn the turbine, but in newer power plants the gases produced by burning of the fuel turn a gas turbine directly. Lightning strikes during a night-time thunderstorm. ... This article is about the chemical process. ... WWII era steam turbine used for ship propulsion. ... This machine has a single-stage radial compressor and turbine, a recuperator, and foil bearings. ...

With global modernization in the 20th and 21st centuries, the thirst for energy from fossil fuels, especially gasoline derived from oil, is one of the causes of major regional and global conflicts. A global movement toward the generation of renewable energy is therefore underway to help meet the increased global energy needs. Renewable energy (sources) or RES capture their energy from existing flows of energy, from on-going natural processes, such as sunshine, wind, flowing water, biological processes, and geothermal heat flows. ...

The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming. A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere. Carbon dioxide is an atmospheric gas comprised of one carbon and two oxygen atoms. ... Top: Increasing atmospheric CO2 levels as measured in the atmosphere and ice cores. ... The generalised concept of radiative forcing in climate science is any change in the radiation (heat) entering the climate system or changes in radiatively active gases. ... Global mean surface temperatures 1856 to 2005 Mean temperature anomalies during the period 1995 to 2004 with respect to the average temperatures from 1940 to 1980 Global warming is an observed increase in the average temperature of the Earths atmosphere and oceans. ... Biofuel is any fuel that derives from biomass â€” recently living organisms or their metabolic byproducts, such as manure from cows. ...

A limited resource

Oil is believed to be a finite resource. Significant usage of renewable energy sources such as hydroelectricity and nonrenewable nuclear power and scientific advances have reduced the dependency on fossil fuels, of which household usage has increased nonetheless. Petroleum is also important because it is a source of petrochemicals, for which there are a vast variety of uses.

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. The supply and demand model describes how prices vary as a result of a balance between product availability at each price (supply) and the desires of those with purchasing power at each price (demand). ...
