Although the use of fossil fuels may seem beneficial to our lives, this act is playing a role on global warming and it is said to be dangerous for the future. Moreover, these environmental pollutions impacts on the human beings because its particles of the fossil fuel on the air cause negative health effects when inhaled by people. These health effects include premature death, acute respiratory illness, aggravated asthma, chronic bronchitis and decreased lung function. So, the poor, undernourished, very young and very old, and people with preexisting respiratory disease and other ill health, are more at risk. 34 Industry main articles: coal industry and petroleum industry further information: Fossil fuel exporters and Fossil fuels lobby Economic effects Europe spent 406 billion on importing fossil fuels in 2011 and 545 billion in 2012. This is around three times more than the cost of the Greek bailout up to 2013. In 2012 wind energy in Europe avoided.6 billion of fossil fuel costs. 35 A 2014 report by the International Energy Agency said that the fossil fuels industry collects 550 billion a year in global government fossil fuel subsidies.
Emissions reduction with new technology scania group
Coal mining methods, particularly mountaintop removal and strip mining, have negative environmental impacts, and offshore oil drilling poses a hazard to aquatic organisms. Oil refineries also have negative environmental impacts, including air and water pollution. 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 best 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.". 32 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. Citation needed According to rodman. Griffin, "The burning of coal and oil have saved inestimable amounts of time and labor while substantially raising living standards around the world".
28 Combustion of fossil fuels generates sulfuric, 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, which are released into the atmosphere. In 2000, about 12,000 tonnes of thorium and 5,000 tonnes of uranium were released worldwide from burning coal. 29 It is estimated that during 1982, us coal burning released 155 times as much radioactivity into the atmosphere as the Three mile Island accident. 30 Burning coal also generates large amounts of bottom ash and fly ash. These materials are used in a wide variety of applications, utilizing, for example, about 40 of the us production. 31 Harvesting, processing, and distributing fossil fuels can also create environmental concerns.
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, hydropower dams and transmission lines have significant effects on water and biodiversity." 27 Carbon dioxide variations over presentation the last 400,000 years, showing a rise since the industrial revolution According. Scientist Jerry mahlman and usa today: Mahlman, who crafted the ipcc language used to define levels of scientific certainty, says the new report will lay the blame at the feet of fossil fuels with "virtual certainty meaning 99 sure. That's a significant jump from "likely or 66 sure, in the group's last report in 2001, mahlman says. His role in this year's effort involved spending two months reviewing the more than 1,600 pages of research that went into the new assessment.
Biodiesels are being produced by several companies and source of great research at several universities. Some of the most common and promising processes of conversion of renewable lipids into usable fuels is through hydrotreating and decarboxylation. Environmental effects Global fossil carbon emission by fuel type, 18002007. Note: Carbon only represents 27 of the mass of CO2 main article: Environmental impact of the energy industry The United States holds less than 5 of the world's population, but due to large houses and private cars, uses more than 25 of the world's supply. 25 As the largest source. Greenhouse gas emissions, co2 from fossil fuel combustion, accounted for 80 percent of its weighted emissions in 1998. 26 Combustion of fossil fuels also produces other air pollutants, such as nitrogen oxides, sulfur dioxide, volatile organic compounds and heavy metals.

Flows are production of fossil fuels from these reserves. The most important part of primary energy sources are the carbon based fossil energy sources. Coal, oil, and natural gas provided.6 of primary energy production during 2002 (in million tonnes of oil equivalent (mtoe) (34.923.521.2). Levels (proved reserves) during coal: 997,748 million short tonnes (905 billion metric tonnes 19 4,416 billion barrels (702.1 km3) of oil equivalent Oil: 1,119 billion barrels (177.9 km3) to 1,317 billion barrels (209.4 km3) 20 Natural gas: 6,1836,381 trillion cubic feet (175181 trillion cubic metres 20 1,161 billion. Hodgson, a senior research fellow emeritus in physics at Corpus Christi college, oxford, expects the world energy use is doubling every fourteen years and the need is increasing faster still and he insisted in 2008 that the world oil production, a main resource of fossil.
24 The principle of supply and demand holds 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 leeds may become economically viable in the near future. Different alternative sources of energy include nuclear, hydroelectric, solar, wind, and geothermal. One of the more promising energy alternatives is the use of inedible feed stocks and biomass for carbon dioxide capture as well as biofuel. While these processes are not without problems, they are currently in practice around the world.
16 Oil shale and similar materials are sedimentary rocks containing kerogen, a complex mixture of high-molecular weight organic compounds, which yield synthetic crude oil when heated ( pyrolyzed ). These materials had yet to be fully exploited commercially. 17 With additional processing, they can be employed in lieu of other already established fossil fuel deposits. More recently, there has been disinvestment from exploitation of such resources due to their high carbon cost, relative to more easily processed reserves. 18 Prior to the latter half of the 18th century, windmills and watermills provided the energy needed for industry such as milling flour, sawing wood or pumping water, and burning wood or peat provided domestic heat. The widescale use of fossil fuels, coal at first and petroleum later, to fire steam engines enabled the Industrial revolution.
At the same time, gas lights 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 oil, both made from fossil fuels. Other forms of transportation, railways and aircraft, also required fossil fuels. The other major use for fossil fuels is in generating electricity and as feedstock for the petrochemical industry. Tar, a leftover of petroleum extraction, is used in construction of roads. Reserves see also: Oil reserves levels of primary energy sources are the reserves in the ground.

The use of coal as a fuel predates recorded history. Coal was used to run furnaces for the melting of metal ore. Semi-solid hydrocarbons from seeps were also burned in resume ancient times, 12 but these materials were mostly used for waterproofing and embalming. 13 Commercial exploitation of petroleum began in the 19th century, largely to replace oils from animal sources (notably whale oil ) for use in oil lamps. 14 Natural gas, once flared-off as an unneeded byproduct of petroleum production, is now considered a very valuable resource. 15 Natural gas deposits are also the main source of the element helium. Heavy crude oil, which is much more viscous than conventional crude oil, and tar sands, where bitumen is found mixed with sand and clay, began to become more important as sources of fossil fuel as of the early 2000s.
Many of television the coal fields date to the carboniferous period of Earth's history. Terrestrial plants also form type iii kerogen, a source of natural gas. There is a wide range of organic, or hydrocarbon, compounds in any given fuel mixture. The specific mixture of hydrocarbons gives a fuel its characteristic properties, such as boiling point, melting point, density, viscosity, etc. Some fuels like natural gas, for instance, contain only very low boiling, gaseous components. Others such as gasoline or diesel contain much higher boiling components. Importance see also: Fossil fuel power plant Fossil fuels are of great importance because they can be burned ( oxidized to carbon dioxide and water producing significant amounts of energy per unit mass.
atmospheric carbon dioxide per year. 10 Carbon dioxide is a greenhouse gas that increases radiative forcing and contributes to global warming. A global movement towards the generation of renewable energy is underway to help reduce global greenhouse gas emissions. Contents Origin Since oil fields are located only at certain places on earth, 11 only some countries are oil-independent; the other countries depend on the oil-production capacities of these countries Aquatic phytoplankton and zooplankton that died and sedimented in large quantities under anoxic conditions millions. Over geological time this organic matter, mixed with mud, became buried under further heavy layers of inorganic sediment. The resulting high levels of heat and pressure caused the organic matter to chemically alter, first into a waxy material known as kerogen which is found in oil shales, and then with more heat into liquid and gaseous hydrocarbons in a process known as catagenesis. Despite these heat driven transformations (which may increase the energy density compared to typical organic matter the embedded energy is still photosynthetic in origin. 1 Terrestrial plants, on the other hand, tended to form coal and methane.
Fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. Methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates. The theory that fossil fuels formed from the fossilized remains of dead plants 4 by exposure to heat and database pressure in the earth's crust over millions of years 5 was first introduced by georgius Agricola in 1556 and later by mikhail Lomonosov in the 18th. The United States Energy Information Administration estimates that in 2007 the primary sources of energy consisted of petroleum.0, coal.4, natural gas.0, amounting to.4 share for fossil fuels in primary energy consumption in the world. 6 Non-fossil sources in 2006 included nuclear.5, hydroelectric.3, and others ( geothermal, solar, tidal, wind, wood, waste ) amounting.9. 7 World energy consumption was growing about.3 per year. Although fossil fuels are continually being formed via natural processes, they are generally considered to be non-renewable resources because they take millions of years to form and the known viable reserves are being depleted much faster than new ones are being made. 8 9 The use of fossil fuels raises serious environmental concerns.
