An exploitation of the energy use of fossil fuels

Over geological time this organic mattermixed with mudbecame buried under further heavy layers of inorganic sediment.

The resulting high levels of heat and pressure caused the organic matter to chemically alterfirst into a waxy material known as kerogen which is found in oil shalesand 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 matterthe embedded energy is still photosynthetic in origin.

Terrestrial plants also form type III kerogena 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.

Fossil fuel power plant Fossil fuels are of great importance because they can be burned oxidized to carbon dioxide and waterproducing significant amounts of energy per unit mass. 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 ancient times, [11] but these materials were mostly used for waterproofing and embalming. Heavy crude oilwhich is much more viscous than conventional crude oil, and tar sandswhere bitumen is found mixed with sand and clay, began to become more important as sources of fossil fuel as of the early s.

These materials had yet to be fully exploited commercially. More recently, there has been disinvestment from exploitation of such resources due to their high carbon costrelative to more easily processed reserves.

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 oilboth made from fossil fuels.

Other forms of transportation, railways and aircraftalso required fossil fuels. The other major use for fossil fuels is in generating electricity and as feedstock for the petrochemical industry. Tara leftover of petroleum extraction, is used in construction of roads.

Oil reserves Levels of primary energy sources are the reserves in the ground. 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 Levels proved reserves during — Coal: Peak oilHubbert peak theoryRenewable energyand Energy development P. 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 that the world oil production, a main resource of fossil fuel, is expected to peak in ten years and thereafter fall.

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 reservesbut may become economically viable in the near future.

Different alternative sources of energy include nuclearhydroelectricsolarwindand 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. 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, — According to Environment Canada: 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 dioxidewhich 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. 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 thoriumwhich are released into the atmosphere.Exploitation of Fossil Fuels Fossil fuel is a term for a non-renewable energy source. Once a fossil fuel is extracted, it does not replenish itself. Fossil fuels like oil, natural gas and coal are all believed by scientists to have formed more than million years ago.

There is an urgent need to stop subsidizing the fossil fuel industry, dramatically reduce wasted energy, and significantly shift our power supplies from oil, coal, and natural gas to wind, solar, geothermal, and other renewable energy sources.

Nowadays, we still use fossil fuels as the main source of energy while some countries have tried the implementation of renewable energy. There had long been debated the effects of renewable energy vs fossil fuels, discussing the .

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. The use of coal as a fuel predates recorded history.

Total U.S. primary energy consumption in was about quads, with fossil fuels—natural gas, petroleum, and coal—supplying about 85 percent, as shown in Table (EIA, a). 1 Liquid fuels (derived primarily from petroleum) were the main contributors, accounting for 40 percent of total.

Fossil Fuel. Definition. Fossil fuel is a hydrocarbon deposit, such as petroleum, coal, or natural gas, derived from the accumulated remains of ancient plants and animals and used as age of the organisms and their resulting fossil fuels is typically millions of .
