Fossil Fuels
Energy, whether it was sunlight or heat from a wood fire, has always been important to society. However, with the onset of the industrial revolution over 200 years ago, wood alone could no longer support the increasing energy demand. The world quickly turned to coal to satisfy its energy needs, and it has been reliant on fossil fuels ever since. Despite the inroads renewable and nuclear energies have made in recent decades, the vast majority of energy used by society still comes from the three main fossil fuels: petroleum, natural gas, and coal. As a result, it is important to know how these fuels were formed, the rates at which they are produced and consumed, and how much is economically recoverable for future use.

However, when temperatures exceed 160¢ªC, all of the oil in the sources rock burns off to form natural gas. So source rock that is exposed to these high temperatures accounts for the formation of natural gas wells in which there is no oil.
The source rock is often times buried beneath a layer of porous sedimentary rock. The pores in this rock are filled with water, so it is called the reservoir rock. Since oil and gas float on water, the hydrocarbons in the source rock rise through the reservoir rock. They continued to rise until they encountered an impermeable layer of rock, where they stop and form a reserve. The natural gas, since it is lighter, will always rest on top of any oil in the reserve(Marshak 433-4).
Oil has become the most widely used energy source in the world. This is because oil is both easy to transport and flexible in its uses, unlike natural gas, which is costly to transport, and coal, which currently has limited applications. The result is that thirty-eight percent of energy used in the United States comes from the burning of oil(Ristinen 17). Transportation, which gets almost ninety-eight percent of its energy from oil, accounts for most of the oil use in the US(Ristinen 20). This is due to the fact that the price of oil in the US does not reflect its true cost. With the combination of high subsidies and low taxes on oil, the US government has produced a market in which gasoline is cheap and abundant. When compared to other
Thomas Edison once said, “I have not failed 10,000 times. I have succeeded in proving that those 10,000 ways will not work,” he said of his method of experimentation. “When I have eliminated the ways that will not work, I will find the ways that will work.” Up until the late 1830’s electricity was derived from many non-renewable sources such as coal, oil, and natural gases. These are also known as fossil fuels. Fossil fuels are the major energy sources that are being used in the world today. The production of fossil fuels account for more than one-third of U.S global emissions, which trap heat, steadily drive up the plant’s temperature, and create harmful impacts on our health, our environment, and our climate. Their sources are limited and depleting at a faster
In this paper, we focus on using fossil fuels causing climate change. Fossil fuels are fuels formed natural resources such as coal, petroleum and natural gas, which are the most widely used fuel and industrial chemicals in the world. Since industrial revolution, fossil fuels bring a very great quantity convenience and technological products. So we can use cars, planes and all modern products. But fossil fuels cause climate change at the same time. Greenhouse gas, nitrous oxides and a great deal of harmful gas which are from fossil fuels are causing serious environmental problems. Therefore we need to be concerned about the problems caused by fossil fuels and the solutions.
When people hear the word oil it is commonly interpreted as gas, but the oil that we drill is not what goes into our cars. The oil that is retrieved from the ground is called crude oil, Oil in its raw natural form and when it becomes refined it is used in plastics, rubber, and gasoline. ”Gasoline is a volatile, flammable liquid obtained from the refinement of petroleum, or crude oil. It was originally discarded as a byproduct of kerosene production.” The first oil well was found and harvested in Titusville, Pennsylvania by a man named Edwin L. Drake, in 1859. The well was about 70 feet deep (How gas). It pumped between 20-40 barrels a day
The most important of these is the Permian Basin. In the latter half of the Paleozoic era, sediments rich in organic matter accumulated here when a shallow sea got cut off from the main oceans and evaporated off, leaving lots of dead critters and evaporites. These sediments eventually got buried and compressed, causing the oil and gas to form "pockets in permeable rock, surrounded by impermeable rocks so that they couldn't escape. There the fluid sits until someone pokes a hole (well) into the area and the contents rush out as the tremendous pressure is released. Other areas of Texas with notable petroleum sources include East Texas's Woodbine Formation (formed in the Late Cretaceous), much of the Gulf Coast and the Gulf itself, and various smaller pockets in South and South Central Texas.
Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the buried remains of plants and animals that lived millions of years ago.
After scientists have tested the oil and the rocks, oil companies will begin drilling in the wells and rock samples will be brought to the surface. After the scientists have studied the rock samples from above ground and are convinced that they have found the right type of rock, companies begin drilling production wells. “When the wells first hit the reservoir, some of the oil begins coming to the surface immediately” (“Fossil Energy: How Fossil Fuels Were Formed,” n.d.). However, with today’s technology, oil companies are able to install special equipment to help the oil from spurting hundreds and hundreds of feet from the ground.
They then pump fluid through pipelines into the drilled areas in order to extract materials that would further indicate the presence of oil. Once a company is certain that there is a sufficient amount of oil at a given location to make drilling worthwhile, it sets up a more permanent structure, or platform, from which to extract it. The oil that is pumped out is sent through pipelines back to shore. An offshore facility can pump oil from a field for decades.
Gas and oil is usually formed over thousands and thousands of years under large bodies of water, where organic materials have died. The organic material of plants and animals settle to the bottom of the waters floor and
Besides the ideal physical structure for oil and gas reservoirs formed in the Gulf of Mexico, the nature also prepared all of other necessary conditions to form and accumulate oil and gas, such as organic source, pressure and temperature. According to the chemical and biological description, Oil is basically a mix of naturally occurring organic compounds from within the earth that contain primarily hydrogen, carbon and oxygen. Dead animals, algae and bacteria, which are considered as the fundamental source to form oil and gas, were absolutely abundant at the early Jurassic era, when the Gulf of Mexico basin was just well formed. After the death of living creatures such as animal and plants, most of their bodies are destroyed by bacteria. Some of these organic material settled down to the bottom of the seafloor, where there was no oxygen at all, being protected from the bacterial actions. Through certain chemical reaction, the leftover organic material mixed with sediments turned into a substance named Kerogen .
Natural gas is made up of just the two elements, Carbon and Hydrogen. All of the natural gas we use today began as microscopic plants and animals living in the ocean. As they become buried ever deeper, heat and pressure begin to rise. Natural gas deposits migrated until they were caught under impermeable layers of rock or clay, where they were trapped.

Abstract – The world can’t be imagined without IC Engines ,as their applications are wider in various fields. And mainly used input for this engines are fossil fuels. But the challenge in this is decreasing rate of resources. The fossil fuels may not be available after some years if they used in the same way .Not only the fossil but also the electric power is the non renewable energy, This paper concentrates to run the engine without fossil fuels or electricity.
The formation of the other two fossil fuels (crude oil and natural gas) took millions of years just like coal. Oil and gas come from the remains of small animals and plants. Long ago, when the animals and plants died, they sank to the bottom of the sea. The dead matter formed a large mass, which over time was covered by layers of sand, silt, and mud. As the weight of the sediment increased, the mass became more and more compressed. Then, the heat and pressure of the Earth eventually turned the mass into oil and gas. If the heat applied during the formation was low, then more oil was produced than gas. If the temperature was
Fossil fuels are essential to life on earth as we know it today. Our world would certainly be much different if it weren’t for such seemingly simple things such as coal, oil, and natural gas. These basic elements of life on earth may not seem like a major concern to some people until we put into perspective how they have shaped our world today. Civilizations have been built, economies have risen and crumbled, and even wars have been fought over these precious fossil fuels. However, these fossil fuels serve us in ways we may never truly appreciate, as long as we use them as recklessly as we do now. The major entity about fossil fuels is concerning their longevity and permanence in our world, and we all know, they will be around forever.
The US consumed 142 billion gallons of gasoline in 2007 and the tax applied on it is 18. 4 cents on one gallon. All around the US, there are around 162,000 retail gasoline outlets. With the price of crude oil hovering around $100 a barrel, it is no wonder that concern is growing about the gas prices being so high. After all, modern economies are kept moving by this lifeblood. For instance, in the United States alone personal vehicles consume more than 140 billion gallons of diesel fuel and gasoline per year.However, there are several factors that contribute to the gas prices being so high. Given below are a few of them. Increasing Demand for Oil One of the main catalysts for the incessant rise in gas prices has been one of the most
Finding energy sources is an issue that polarizes scientists, politicians and citizens alike. The most critical points of this debate are at fossil fuels and renewable energy. Energy efficiency is arguably the most dire concern facing the planet, because it significantly impacts all areas of everyday life. Common ground can be found in this controversy because both parties do agree that humans have a responsibility to future generations. That responsibility is to preserve the resources of the Earth, while offering this generation energy that is affordable and accessible.
