Fossil fuels are fuels formed from the remains of ancient organisms through decomposition over millions of years. The three main types are coal, oil, and natural gas. Coal forms from decomposed plant matter and is the most abundant fossil fuel in the United States. Oil forms from the remains of marine organisms and diatoms, and is a valuable resource extracted in many countries like Russia and Saudi Arabia. Natural gas forms from methane and is colorless, odorless, and usually found near oil deposits underground.
Introduction by Hira Khan; Overview of fossil fuels formed from anaerobic decomposition and their energy significance.
Fossil fuels categorized into coal, oil, and natural gas, highlighting their fundamental differences.
Coal described as the most abundant fossil fuel in the U.S.; a nonrenewable energy source from ancient plants.
Oil's formation linked to ancient diatoms; main production countries listed; uses of oil examined. Details about natural gas, its formation processes, and its constituents, including methane. Coal, oil, and natural gas applications in power generation, manufacturing, and consumer products.
Role of refineries in converting crude oil into valuable petroleum products essential for the economy.
Crisis reports on the Exxon Valdez and Deep Water Horizon oil spills, detailing their environmental impacts.
Additional images or information not elaborated in the previous slides.
Fossil fuels arefuels formed by natural resources such as anaerobic decomposition of buried dead organisms.Fossil fuels are of great importance because they can be burned, producing significant amounts of energy (http://en.wikipedia.org/wiki/Fossil_fuel)What are fossil fuels?
HardBlackRock-likeMost abundant fossilfuel produced in the United StatesA nonrenewable energy source because it takes millions of years to create.Energy in coal comes from the energy stored by plants that lived hundreds of millions of years ago(http://www.eia.doe.gov/kids/energy.cfm?page=coal_home-basics)Coal Facts

Formed more than300 million years ago.Scientists say that tiny diatoms (diatoms- sea creatures the size of a pin head and can convert sunlight directly into stored energy) are the source of oil.Oil has been used for more than 5,000-6,000 years.Is produced in;Russia, Saudi Arabia, United States, Iran, and China(http://www.eia.doe.gov/kids/energy.cfm?page=oil_home-basics)(http://web.me.com/davgen1/ILS_12-22/Fossil_Fuels.html)Oil Facts

Is lighter thanairFirst discoveries of natural gas seeps were made in Iran.Mostly made up of a gas called methane.(methane-simple chemical compound that is made up of carbon and hydrogen atoms.)Usually found near petroleum underground.Pumped from below ground and travels in pipelines to storage areas.No odorCan’t see it(http://web.me.com/davgen1/ILS_12-22/Fossil_Fuels.html)Natural Gas Facts

Formedwhen peat isaltered physically and chemically.Formedfrom the remains of vegetation that grew as long as 400 million years ago.Process is called "coalification." (http://www.ket.org/trips/coal/agsmm/agsmmhow.html)How Coal is Formed

Main types ofcoal - anthracite, bituminous and lignite. Anthracite-hardest, more carbon, higher energy contentBituminous-In betweenLignite-softest, low in carbon, high in oxygen content and hydrogenPeat-precursor (a substance from which another substance is formed) to coal (http://web.me.com/davgen1/ILS_12-22/Fossil_Fuels.html)Different Stages of Coal Formation
9.
Almost 93% ofthe coal used in the United States is used for generating electricity.Separated ingredients of coal (such as methanol and ethylene) are used in making; Tar, Fertilizers, Plastic, Medicins, Coke, Steel(http://www.eia.doe.gov/kids/energy.cfm?page=coal_home-basics)How Coal is used as a Fossil Fuel

Oil was formedfrom the remains of animals and plants (diatoms) that lived millions of years ago in a marine (water) environment before the dinosaurs.(http://www.eia.doe.gov/kids/energy.cfm?page=oil_home-basics)(http://web.me.com/davgen1/ILS_12-22/Fossil_Fuels.html)How Oil is Formed

Methane, a gasor compound that has one carbon atom and four hydrogen atoms.(http://www.eia.doe.gov/kids/energy.cfm?page=natural_gas_home-basics)How Natural Gas is Formed

Produce; Steel, Glass,Paper, Clothing, Brick, Electricity Some products that use natural gas as a raw material are: Paints, Fertilizer, Plastics, Antifreeze, Dyes, Photographic film, Medicines, and Explosives.

A refineryis afactory that takes a raw material (crude oil) and transforms it into petrol and hundreds of other useful products.It is important because many products like gasoline wouldn’t be made without refineries.(http://www.moorlandschool.co.uk/earth/oilrefinery.htm)Refineries and Why They are Important to the Production of Fossil Fuels

unprecedented underwater leakspreads oil across the northern Gulf of Mexico between the mouth of the Mississippi River and Florida.Coast Guard says remote underwater cameras detect the well is leaking 1,000 barrels of crude oil per day .The Interior Department orders safety inspections of all 30 deepwater drilling rigs and 47 deepwater production platforms.The Coast Guard says the leak will affect the Gulf shore.U.S. officials close areas affected by the spill to fishing for an initial period of 10 day .Exxon Valdez Oil

Deep Water Horizonoil rig exploded in the Gulf of MexicoThere is some progress cleaning it up Last update showed that it was getting closer to the coast of Louisiana.reached more than the half the size of the Valdez disaster.more than 1 million gallons of water has been cleaned from oil and 367881 feet of oil booms have been deployed.BP has been trying all sorts of engineering efforts to stop the leak, which includes the four story high containment dome which was to be placed over the leakage.Deep Water Horizon
