Fossil Fuels Fossil Fuels Fission Hydroelectric Biomass ... Fusion Coal Contents Acid Rain Clean Coal Technology Availability of Coal Coal History About 300 million years ago, enormous ferns and other prehistoric plants were common on the swamp-like earth. When those plants died and fell to the ground, they were covered with water and they slowly decomposed. As decomposition took place in the absence of oxygen, much of the hydrogen content of the matter was eroded away, leaving a material rich in carbon. The material was compressed over the years by sand and dirt, leaving the form of carbon known as coal. Types The nature of coal is such that the higher the carbon content, the more cleanly and brilliantly the coal burns. Thus "peat", which is the state of the decomposing plants before being compressed, is a weak, impure substance. The other states of coal, from lowest carbon content to highest, are "lignite," bituminous coal, and anthracite coal. If the coal is heated and compressed even more, the result is "graphite," almost completely pure carbon. Nearly all the different forms of coal are used in some way or another. For instance, peat has been used for burning in furnaces, whereas bituminous coal is used extensively for the generation of electricity. "Coke," a very pure form of coal with a high heat content is used primarily in the steel industry, where high temperatures are required.

Fossil fuels are relatively easy to use to generate energy because they only require a simple direct combustion. However, a problem with fossil fuels is their environmental impact. Not only does their excavation from the ground significantly alter the environment, but their combustion leads to a great deal of air pollution Follow the link to learn more about how fossil fuels can create energy.

Fossil Fuels Conventional power stations burn coal, oil or gas to produce electricity. Coal, oil and gas are called fossil fuels because they form over millions of years through the decay, burial and compaction of rotting vegetation on land (coal), and marine organisms on the sea floor (oil and gas). Burning fossil fuels in this way releases large quantities of sulphur dioxide and nitrogen oxides which can cause acid rain. Coal is a solid fuel formed over millions of years by the decay of land vegetation. Over time, successive layers become buried, compacted and heated, a process through which the deposits are turned into coal. Coal is widely used in the generation of electricity because it is a highly concentrated energy source. However, it is not a particularly "clean" fuel, releasing more acidic pollution than either oil or gas. Coal was the first fossil fuel to be exploited on a large scale during the 19 th century with the beginning of the Industrial Revolution. Before the commercial introduction of electricity, coal was primarily used in industrial boilers to create steam energy to power machinery. Oil is formed from the remains of marine microorganisms (microscopic animals and plants) deposited on the sea floor. As they accumulate over millions of years they gradually infiltrate the microscopic cavities of the sea floor sediment and rock where they decay. The resulting oil remains trapped in these spaces, forming oil reserves which can be extracted through large drilling platforms. The use of oil increased significantly after the Second World War. In the early 1970s, approximately 40% of global fossil fuel use came from oil, but during the 1990s this figure has decreased. Improved energy efficiency has caused oil consumption to decline in many developed, industrialised countries, as well as shifts to other fuels such as natural gas and nuclear energy. Decreasing use of oil is also resulting from tougher environmental restrictions concerning its use in some regions.

FOSSILS INTO FUELS Crude oil, natural gas and coal are fossil fuels. Fossil fuels are very precious resources because they are non-renewable (once they're used, that's it!). We can also make lots of organic chemicals from them, needed to make products such as paints, detergents, polymers (including plastics), cosmetics and some medicines. Fossil fuels were formed from the fossillized remains of dead plants and animals that once lived millions of years ago. Oil and natural gas are the products of the deep burial and decomposition of dead plants and animals. Heat and pressure, in the absence of oxygen, transform the decomposed material into tiny pockets of gas and crude oil. The oil and gas then migrates through the pores in the rocks to eventually collect in reservoirs. Coal comes mainly from dead plants which have been buried and compacted beneath sediments. Most coal originated as peat in ancient swamps created many millions of years ago. What is crude oil? Crude oil is a complex mixture of hydrocarbons with small amounts of other chemicals such as sulphur. The crude oil is useless as a mixture and must be sent to an

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.

33. Energy Information Sheets - Nuclear Power Generation Nuclear Power Generation. Electricity has been generated by burning fossil fuels(coal, oil, and gas) since before the turn of the twentieth century. http://www.eia.doe.gov/neic/infosheets/nuclear.htm

Nuclear Power Generation Electricity has been generated by burning fossil fuels (coal, oil, and gas) since before the turn of the twentieth century. For over three decades, however, a nonfossil fuel, uranium, also has been used to produce electricity. The first U.S. nuclear power plant went into commercial operation in 1957 at Shippingport, Pennsylvania. Since then, the use of nuclear-generated electricity has grown substantially in the United States. The U.S. nuclear power industry achieved its third straight year of record power generation levels during 2000 Total power generated was 754 billion kilowatthours, 3.5 percent above the previous record of 728.1 billion kilowatthours set in 1999. This represents continued growth in power production for the nuclear power industry that had produced only 577.0 billion kilowatthours as recently as 1990. The record year 2000 output was achieved despite the fact that the industry had only 104 operating reactors compared to 111 operating reactors as recently as 1990. Record output was attained through an annual net capacity factor of 88.1 percent during 2000 compared to 85.3 percent in 1999 and 66 percent in 1990. Nuclear generation surpassed 700 billion kilowatthours for the second consecutive year. For eight of the first nine months of 2000, nuclear generation was higher than in the same months during 1999. The nuclear industry generated 69.2 billion kilowatthours in July 2000, the highest level for the U.S. nuclear power industry ever.

previous next title page contents 6. Conclusions - The Carbon Logic A number of conclusions can be drawn from the present analysis in relation to the use of fossil fuels and indeed of greenhouse gas emissions over the next century. With action on deforestation a budget for fossil fuels over the next century of around 225 GtC may enable long term warming to be limited to around 1 o C. The present findings are consistent with earlier work, taking into account both the improvements in scientific knowledge over the past decade and the changes in the international policy context. The conclusion that there must be an ecological limit to burning fossil fuels is robust to a wide range of assumptions. Even if the climate is less sensitive to human interference than the current evidence suggests, or governments fail to take a precautionary approach to setting limits, a `carbon budget' is will still result which is less than current fossil fuel reserves. This has several implications: * Coal use needs to be phased out as rapidly as possible. Only a small fraction of the economically recoverable reserves can ever be used. Coal has the highest carbon intensity of the conventional fossil fuels. Coal is subsidised in many parts of the world and these subsidies should be moved, where necessary, to renewable energy systems. * There should be no further exploration and development of unconventional oil and gas reserves. Estimated economically recoverable volumes of gas and oil in this category are sufficient alone to breach the `carbon budget'. These resources should not be allowed onto the market as doing so will inevitably lead to cost reductions through production scale effects. This can only make it more difficult to phase out fossil fuels.

This report shows the implications for overall fossil fuel use, in the form of a `carbon budget', over the next century if the global community is to prevent dangerous climate change. It is demonstrated that it is only possible to burn a small fraction of the total oil, coal and gas that has already been discovered, if such dangerous changes are to be avoided. Even the reserves of fossil fuels that are considered economic to recover now, with no advances in technology, are far greater than the total allowable `carbon budget'. This conclusion is shown to be robust to a wide range of assumptions about how sensitive the climate is to human interference, and the levels of change that might be considered unacceptable or dangerous.

Home Up Aerial Photos Global Positioning Systems (GPS) [ Energy Generation (Chapter 7): Fossil Fuels and Nuclear Power ] Energy Generation: Energy From Renewable Resources Biomes Biogeography Biodiversity ... 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.

37. SEEN coal. Of all of the fossil fuels, coal is the cheapest, and so, despite the warningsof Rio, it remains the fuel of choice for many countries in the South. http://www.seen.org/pages/energy.shtml

An Introduction to Fossil Fuels Coal Oil Natural gas Coal Between 1973 and 1993, coal use increased by 36 percent, growing fastest in South America (360 percent) and Asia (162 percent) and slowest in Europe (6 percent) . The world now burns more than 3.5 billion tons of coal a year. Countries like China, India, and Brazil, which have their own substantial coal reserves, are expected to burn coal most rapidly. China alone releases 650 million metric tons of carbon from coal-burning per year (about 27 percent of the world total from coal burning)and is projected to double its coal consumption by 2010. At a shadow price of about $20 per ton of carbon , China is now externalizing at least $13 billion in carbon emissions per year from coal burning alone . Global energy use projections suggest that, in large part because of their high coal consumption, China and India will account for more than 20 percent of all carbon dioxide emissions from the global South by 2010. Oil The world now consumes 65 million barrels of oil a day. Oil burned by cars alone produces nearly a fifth of global carbon dioxide; other noxious byproducts include carbon monoxide and nitrogen oxides. Our addiction to oil is directly proportional to our universal addiction to the automobile: Every second, an additional car takes to the road.

Merit Badge Trail Introduction Plate Tectonics Time Scale and History Formation of the Ouachitas ... Careers Geology and Sources of Energy by Steve Sharp, P.E. S ome of our mineral resources can be taken out of the ground and used for fuel. Raw materials have two sources: they can be grown or they can be mined. Coal, oil and gas are collectively called fossil fuels, because they formed from organic (living) matter. Uranium is also a source of energy that is taken out of the ground. These fuels that are mined are called non-renewable resources, because we can't replace them. That's why wise use of our raw materials is important. The ways that electricity was generated in Arkansas in 1997. This data is from the Energy Information Agency. There are several naturally occurring sources of energy that are used in Arkansas to generate electricity. Electricity is perhaps the most readily available form of energy that we all use everyday in our homes, schools, offices, businesses and factories. Coal, natural gas, fuel oil, uranium and falling or flowing water are all used to generate large amounts of electricity in Arkansas. Wind and solar energy are also used by some, but the amount of electricity they generate is very small. Coal, natural gas and the crude oil from which fuel oil can be refined are all present in Arkansas. No minable amount of uranium occurs here.

Fossil Fuels Fossil fuels - coal, oil and natural gas - that we've come to rely on for convenience and prosperity, are destabilizing our climate and polluting our air. Large-scale fossil fuel use began with the industrial revolution. From firewood to natural gas, humans have always sought new energy sources to add light, warmth or power to our lives. For millions of years, we used firewood. Then, around the year 1200 in Europe, firewood began to run out, and we turned to coal - a "fossil fuel", having formed from the slow accumulation of dead plants millions of years ago. The technologies spawned in the industrial era which followed made it possible for us to drill, refine and burn other fossil fuels - oil and natural gas Modern industrial societies burn huge quantities of fossil fuels. We now consume petroleum products, which slowly accumulated over millions of years, at a tremendous rate. The combustion of fuel in our cars, factories and power plants has pumped billions of tonnes of microscopic particules and greenhouse gases into our atmosphere, fundamentally changing its composition. Renewable energy provides an alternative to fossil fuels.
