Examine the role of gas fossil

advantages of fossil fuels

The specific mixture of hydrocarbons gives a fuel its characteristic properties, such as boiling point, melting point, density, viscosity, etc. Thus, the substantial CO2 increase in the atmosphere is a major contributing factor to human-induced global warming.

All fossil fuels can be burned in air or with oxygen derived from air to provide heat. That is probably the most compelling reason to conserve fossil fuels.

The other major use for fossil fuels is in generating electricity and as feedstock for the petrochemical industry. The main source of coal is decomposed plant matter, and oil comes from decayed plankton, a microscopic sea creature.

natural gas

Advances in technology —such as hydraulic fracturing frackingrotary drilling, and directional drilling—have made it possible to extract smaller and difficult-to-obtain deposits of fossil fuels at a reasonable cost, thereby increasing the amount of recoverable material.

More recently, there has been disinvestment from exploitation of such resources due to their high carbon costrelative to more easily processed reserves.

Types of fossil fuels

Fossil fuels also contain radioactive materials, mainly uranium and thorium , which are released into the atmosphere. The most important part of primary energy sources are the carbon based fossil energy sources. The other major use for fossil fuels is in generating electricity and as feedstock for the petrochemical industry. All contain carbon and were formed as a result of geologic processes acting on the remains of organic matter produced by photosynthesis , a process that began in the Archean Eon 4. Car engines also burn fossil fuels, as do many home furnaces and water heaters. Burning petroleum, coal and natural gas fills the air with harmful pollutants, including nitrogen oxides, sulfur dioxide, carbon dioxide, ozone and a host of hydrocarbons. However, there is a more important reason to conserve fossil fuels, and that's to help heal the environment. The use of coal as a fuel predates recorded history. Despite these heat driven transformations which may increase the energy density compared to typical organic matter , the embedded energy is still photosynthetic in origin. Coal mining methods, particularly mountaintop removal and strip mining , have negative environmental impacts, and offshore oil drilling poses a hazard to aquatic organisms. The amounts of fossil fuels that can be recovered economically are difficult to estimate, largely because of changing rates of consumption and future value as well as technological developments. Environmental effects Global fossil carbon emission by fuel type, — Therefore, higher prices will lead to increased alternative, renewable energy supplies as previously uneconomic sources become sufficiently economical to exploit. Different alternative sources of energy include nuclear , hydroelectric , solar , wind , and geothermal.

Griffin, "The burning of coal and oil have saved inestimable amounts of time and labor while substantially raising living standards around the world".
