Extractions: 1998 by Thomas J Brown "To the writers of books upon meteorites, it would be as wickedby which we mean departure from the characters of an established speciesquasi-established, of courseto say that coal has fallen from the sky, as would be to something in a barnyard, a temptation that it climb a tree and catch a bird. Domestic things in a barnyard: and how wild things from forests outside seem to them. Or the homeopathistbut we shall shovel data of coal." Charles Fort, The Book of the Damned The End With a title like The End of Fossil Fuels you may think that this is an article about alternative energy or "free" energy, but alas, it is not. It is an attempt to describe the inadequacy of the term "fossil fuel" and to prevent its further usage in the English language through education in the mysteries of the hydrocarbon structures in the earth. I can't blame people for having used this misleading phrase, being guilty myself. We are regularly taught such misconceptions in school. But one should always be ready to learn new ideas and concepts, especially once the evidence is investigated. The term "fossil fuel" is a standard phrase used in reference to hydrocarbons in their various permutations as petroleum, coals, and natural gas. The argument to be presented here is that hydrocarbon deposits are not "fossilized carbon" at all in the sense implied in the modern usage of that term, that there is a larger "carbon dynamic" eventuating in the earth process. The standard response to this is "well, they FIND fossils in the deposits". This is scientific fact and will not be disputed, fossils certainly are found in SOME deposits, many of them being quite curiouscoal balls and roof ballsand will be discussed in turn as they will further our argument. There are also serious fossil anomalies, evidences of human intelligence which crop up in various coal beds supposedly laid down hundreds of millions of years before humans are supposed to have existed. But we will first look at the hydrocarbon structures themselves.

Extractions: Petroleum, natural gas, and coal are the main sources of energy for modern use. All of these fuels are classified as fossil fuels . The reason they are called fossil fuels is because they are all made from decayed plants and animals that have been preserved in the earth's crust by pressure, bacterial processes and heat. It takes millions of years for these organisms to chemically change into fossil fuels. Liquid fossil fuels, like petroleum , is formed in areas that geologists believe were once covered by oceans or seas. These fuels were formed when dead plants and animals sank to the bottom of the ocean and were covered by sediments. Over long periods of time (millions of years), pressure, bacterial processes, and heat changed the sediments into sedimentary rocks and the plant and animal remains into oil. Eventually underground pools of oil formed when oil migrated through the pores and cracks of rocks and eventually filled these empty spaces. Geolgists search in areas which may contain oil traps. Oil traps include fault lines where porous rock is aligned next to non-porous rock. These traps are also found among folded rock layers. This is an example of a folded-rock-layer oil trap being drilled for petroleum. Oil drills are known as a oil derricks in the petroleum industry.
Fossil Fuels And Their Utilization

http://members.aol.com/profchm/fossil.html

Extractions: It so happens that this is one of my favorite topics. Fossil fuels are fuels that result from the fossilization process of living tissue after millions of years. Coal and crude petroleum are the fossil fuel sources. Evolutionary Stages of Coal Development Coal comes in several developmental stages , peat, lignite, bituminous and anthracite forms of coal. The first two stages are very inefficient producing a small amount of energy per mass of fuel. Lignite can be gasified to natural gas which is a particularly clean burning fuel in itself. Lignite has also been liquefied to produce liquid petroleum fractions. But the gasification and liquefaction process are very expensive and are not cost effective unless the cost of crude petroleum reaches 60.00 a barrel or more. Bituminous (soft coal) and Anthracite (hard coal) are the stages of coal most often mined, processed , and used as fuel. Disadvantages In The Utilization of Coal There are problems with the use of this form of fossil fuel. First, the extraction of the coal from the ground can be very expensive. Most coal deposits lie well below the surface of the earth which means that special drilling , the creation of mine shafts, and the shoring up of these shafts must be paid for. In addition, there is the danger of mine explosions when deposits of natural gas or finely powered coal dust undergoes combustion resulting in an explosion. Breathing of coal dust by the miners leads to a condition known as "black lung". This adds to the cost of the

The crude oil is refined at the two refineries on Oahu, which produce most of the oil products used in Hawaii. They obtained 30.7% of their crude oil from U.S. sources, principally Alaska, in 2000. The rest (approximately 70%) came mostly from Asia. The refined oil products brought into Hawaii also came from a variety of sources about 40% from the U.S. and the remainder (about 60%) principally from Asia. Coal met about 5% of Hawaiis energy needs in 2000. Most of the imported coal was used by AES Hawaii on Oahu. AES Hawaii brings its coal in from Indonesia under a long-term contract. Hilo Coast Power Company on Hawaii, and Hawaiian Commercial and Sugar on Maui import smaller amounts from Australia. The table shows amounts used in 2000. As you can see, only a small amount of the refined product came from the volatile Middle East. However, Indonesia, a prime supplier of both oil and coal, has had recent internal political instability.

Petroleum leads with a share of about 40 percent of total world energy consumption, followed by coal (24 percent) and natural gas (22 percent). Fossil fuels are currently the most economically exploitable sources of power for both personal and commercial use. There are environmental problems associated with extracting, transporting, and using fossil fuels. In particular, in the process of burning fossil fuels, carbon dioxide, a greenhouse gas, is emitted, which raises concerns about the potential of human-induced global warming.

Extractions: SaveClimate.net Source: James J. MacKenzie . March 1996, Updated March 2000. Oil as a finite resource: When is global production likely to peak? Oil makes the single largest contribution to world energy supply, at 40 percent. In 1998, fossil fuels were used to meet about 90 percent of global commercial-energy demand. (See World commercial energy supply In energy terms, oil makes the single largest contribution to world energy supply, at 40 percent, followed by coal at 26 percent and natural gas at about 24 percent. Non-renewable, fossil fuels take millions of years to form, so for all intents and purposes they are finite and, ultimately, exhaustible energy resources. While few would deny that the consumption of fossil fuels will eventually lead to their exhaustion, how and when the various fuels will decline remain uncertain. The debate over conventional crude oil is of especially great interest because of its dominant role in global energy supply. (a) World crude oil prices shows the trend, in constant dollars, in global crude oil prices between 1970 and 1999. The 20-year gradual price decline beginning in 1980 was at least partly the cause of OPEC's cut in oil production with a subsequent rise in the price of crude oil that began in 1999 and led to major jumps in the prices of US petroleum products including gasoline, diesel fuel, and jet fuel.
Beyond Fossil Fuels: The Evolution Of Energy

http://www.pwcglobal.com/extweb/newcolth.nsf/docid/0D7A58A9CC7AB24685256C3100624

Extractions: According to Roy McAlister, a research professor at Arizona State University, since the Industrial Revolution humanity has annually consumed about a million years' worth of fossil fuel resources, from reserves that took 100 million years to accumulate. Such levels of demand on a finite supply of fossilized organisms are unsustainable in the long-term. Fossil fuels will run out later rather than sooner, but it is "greenery" ( The Economist 's new term for green issues), not scarcity, that is unsettling the petroleum industry today. Erratic weather patterns, volatile business climate: the scramble is on to develop new energy sources and economies. But technology offers wildcard after wildcard as a possible solution. How are petroleum companies adapting during this boom-or-bust transitional period? Prophets of doom have been predicting that existing reserves will become inadequate to fuel the world's energy needs since the 1970s. But advances in exploration and production technology have in fact increased the amount of petroleum available to such a degree that even squeezing petroleum out of previously unattractive tar sands has become reasonably economic.

ENERGY FACTS: PETROLEUM
Crude oil, also called petroleum, is a complex mixture of carbon and hydrogen FIGURE3 Economically recoverable fossil fuels are not distributed evenly.
http://www.iclei.org/efacts/petro.htm

Extractions: Since "rock oil" was discovered near Titusville, Pennsylvania, in 1859, by a man drilling for water, crude oil, also called Petroleum, has become the world's foremost source of energy, and the backbone of our industrial society. Oil accounts for 38% of energy use worldwide. Oil's liquid form, high energy density, and relatively clean burning nature make it the most versatile of all fuels. When oil was first discovered, it was primarily used in the form of kerosene for lamps and stoves. Since that time, inventors have developed hundreds of new uses for oil, with the most prominent being the internal combustion engine. Oil was plentiful and cheap throughout most of the twentieth century, resulting in patterns of transportation and land use based upon the private automobile. Oil was also extensively used for heating homes and generating electricity; and since oil was so cheap, it was not used very efficiently. The world's romance with oil came to a crashing halt in 1973, when OPEC (Organization of Petroleum Exporting Countries) unilaterally raised prices and cut production. Oil prices skyrocketed, there were huge lineups for gasoline in the U.S., and oil suddenly became a political issue. More recently, dwindling supplies in the industrial world and concerns over global warming are also beginning to change the world's oil consumption patterns. Crude oil, also called petroleum, is a complex mixture of carbon and hydrogen (hydrocarbons), which exist as a liquid in the earth's crust. On average, crude oil is made up of 83% carbon (C) and 12% hydrogen (H), with the remainder being sulfur, oxygen and nitrogen. Crude oil found in different locations is never exactly the same. Some is black, thick and tar like, while other crude oils are lighter in colour, thinner and more volatile. The carbon and hydrogen in crude oil are thought to have originated from the remains of microscopic marine organisms that were deposited at the bottom of seas and oceans. After having been buried under huge layers of other sediments, the organic material is transformed at high temperature and pressure into crude oil and natural gas. The oil and gas are then squeezed out of the marine shales in which they were deposited, and make their way into porous sedimentary rocks such as sandstones and limestones.

Managing the Environment Energy Generation This topic can be divided up into three sections: fossil fuels and nuclear power "alternative" energy energy conservation Start off with some important points 1) Even though chapter seven in your book is called "Energy Generation," we can't in fact generate energy. We can only harvest it, and transform it from a less useable to a more useable form. This image shows this transformation for crude oil and coal, two kinds of fossil fuel. 2) Where does our energy come from? The main source, by far, is the sun. Minor sources include geothermal energy, nuclear fission, energy from volcanos. 3) When we harvest and use energy, much is lost during the process. Our efficiency of transformation is not great. Energy is lost during the harvesting process, refinement, transportation, and when it is actually used. At each step, we lose energy. 4) The use of energy is critical for our well-being and to maintain our standard of living. Therefore, energy production is tightly linked to economics and to our national security. Protection of our sources of energy is critical.
12.05.2002 - Researchers Say Fossil Fuels For Cooking And Heating May Be Best Fo

http://www.berkeley.edu/news/media/releases/2002/12/05_fuels.html

Extractions: 05 December 2002 By Sarah Yang, Media Relations Berkeley - Contrary to conventional wisdom, the use of fossil fuels for household cooking and heating may make more environmental sense for the estimated 2 billion rural poor in the world, according to a researcher from the University of California, Berkeley. Because they contribute to greenhouse gas emissions, fossil fuels have been largely dismissed as a viable alternative for the one-third of the world's population who now use coal and local biomass - including wood, crop residues and dung - for cooking and heating, said Kirk R. Smith, professor and chair of environmental health sciences at UC Berkeley's School of Public Health. Efforts have been focused on equipping the rural poor with renewable energy sources, such as solar and wind power. But in an editorial appearing this week in the journal Science, Smith argues that switching all 2 billion of the world's poor to liquefied petroleum gas for household use would add a scant 2 percent to the global greenhouse gas emissions of fossil fuels. At the same time, using gas fuel would decrease the environmental impact on local biomass resources.

Extractions: Northeast Energy Education NetCenter Fossil Fuels Fossil fuels have been produced over millions of years by the breakdown of mono-carbons. Fossil fuels include oil, coal, petroleum, and natural gas. All of these fuels are found by drilling wells deep into the ground. When a deposit of the fuels is found, the natural gas is extracted first, followed by the crude oil. From refining this oil we derive all the gasoline and oils used in everyday use. Coal, which once was widely used as a fuel, has now been virtually eliminated as a heating fuel in the U.S. because of the toxic smog it produces. It is, however, still used to produce electricity. New technology, including "scrubbers," makes the smoke less toxic. Recent concerns about pollutants produced by the combustion of heating oil and automobile gas has prompted the industry to produce much safer, cleaner fuels. As a result, the amount of toxins in the air has dropped.
